0000011518 00000 n Most affected children are better able to tolerate sucrose and maltose as they get older. He has had a couple times of blood in his stool throughout all of this. The most common form of disaccharidase disorder is lactase deficiency, when . 0000024002 00000 n Genetic testing for the primary (adult-type) lactase deficiency is available in some commercial laboratories. 1571-6. I removed breads, flour products, sugars, and carbohydrates from my diet. The most definitive method of diagnosing deficiency in any of disaccharide enzymes is by measuring the activity of the enzyme in the epithelial cells of the small intestine.11 This technique involves taking an endoscopic biopsy of the epithelium and homogenizing the tissue. If you are able to confirm that the patient has disaccharidase deficiency, what treatment should be initiated? However, 80 to 85% of whites of Northwest European descent produce lactase throughout life and are thus able to digest milk and milk products. It occurs in the whey (liquid) part of milk. The human trehalase gene (TREH) is located on chromosome 11 at locus 11q23. Undigested disaccharides, such as lactose, create an osmotic load that causes diarrhea. Soft cheeses contain a higher percentage of whey, and consequently, a higher level of lactose and may not be tolerated by the lactase deficient person. vol. The amount of supplement that may be required will depend on individual tolerances to the disaccharide-containing food; some people will be able to tolerate a small amount of the food and so any deficiencies will be minimal. I wonder if they could still do the breath test for SIBO since he has already started Flagyl? Congenital lactase deficiency is a rare disease that is inherited in an autosomal recessive fashion. The parents of a child with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. CARBOHYDRATES provide a substantial proportion of the total caloric content of our diet. Disaccharidase deficiency was demonstrated in the intestinal mucosa of a variety of malabsorption states, especially adult celiac disease (nontropical sprue). Plain protein means foods that have been prepared with no sauce or seasonings. This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. Lactase, the enzyme that breaks down lactose, splits the lactose into two monosaccharides or single sugars: glucose and galactose. Author T M Bayless. What caused this disease to develop at this time? 0000009149 00000 n These common symptoms are frequently misdiagnosed as a food allergy or intolerance. Some individuals find that slowly-digestible carbohydrates, such as whole grains, are easier to tolerate. American cheese slices and Velveeta cheese products are examples of processed cheese products. 10. In cases where mucosal recovery is possible following treatment of the underlying cause (e.g., celiac disease) complete symptom resolution can be anticipated and eventually it should be possible to resume ingestion of all disaccharidases. You need to read labels carefully because some whole grain products contain added sugars, including sucrose. Secondary deficiency: If you have damage to the intestinal cells caused by infection, food allergy, or strong drugs, then it is usually temporary. Congenital sucrase-isomaltase deficiency occurs in about 0.2% in North Americans of European origin and about 10% in the Eskimos of Greenland. Once it starts, removal of all maldigested carbohydrate is needed to interrupt the cycle and allow the system to return to normal. Alternatively, supplementation of dairy products with lactase of microbiologic origin may be suggested. See Figure 1. Most individuals with CSID can eat dairy products such as cows milk, ricotta cheese, plain cottage cheese, sour cream, butter, cream, whipping cream, and hard cheeses like cheddar, Colby, mozzarella, Swiss, parmesan, and provolone. Small intestinal glucoamylase deficiency and starch malabsorption: a newly recognized alpha-glucosidase deficiency in children. Every individuals case of CSID is unique, so beneficial diets can vary considerably. If the baby is not allergic to milk, a milk-based formula that is free from lactose and sucrose is suitable. These individuals would probably show low levels of maltase and isomaltase (palatinase) activity. Gradual reintroduction of disaccharides, one by one, should determine exactly which disaccharide is not tolerated. Some rats of the ZD group . 0000010898 00000 n New Jersey: Rutgers University Maltase: Abnormal Range is less than 100 U* She said that she has never had someone have all 4 levels low. Most individuals with CSID can tolerate tofu. startxref A plain abdominal x-ray demonstrating gaseous distension of the large intestine can be seen in disaccharide malabsorption. Gasbarrini A, Corazza GR, Gasbarrini G, et al: Methodology and indications of H2-breath testing in gastrointestinal diseases: The Rome Consensus Conference. Alternatively, the mother can pump her breastmilk and treat the milk with lactase drops (4 drops per 250 mL milk), and allow the enzyme to act for 24 hours in the fridge. Disaccharidases are enzymes that break down complex sugars, such as lactose, into simple sugars, like glucose, so the nutrients can be absorbed in the intestine. Infant formulas that are lactose free and sucrose free can be given to a disaccharidase-deficient infant. Poor weight gain (occasional and controversial). 1. You may also find sucrose hidden in your breakfast cereal or yogurt. It may be beneficial for you to keep a copy of your or your childs disaccharidases small bowel biopsy results. You can use the food composition tables on this website to determine the starch levels in food items. Increased intestinal gas may occur 30 minutes to hours after ingestion of the sugar, and the distension of bowel wall leads to crampy abdominal pain. Recovery from the underlying disease is followed by an increase in activity of the enzyme. 1972 Jun;60(6):478-82. Intestinal mucosal damage associated with many diseases results in secondary disaccharidase deficiencies. Curr Opin Gatroenterol. Disaccharide deficiency (usually of lactase) can be acquired or, rarely, congenital. Further collections of exhaled breath are obtained at 30 minute intervals for up to 3 hours. It is recommended that you avoid processed cheeses or cheese products since many of these food items contain sucrose or starch fillers. The increase in speed with which food passes through the digestive tract results in inadequate enzymatic breakdown (digestion) of the food, thus increasing the amount of substrate available for microbial fermentation in the large bowel. The prevalence of congenital sucrase-isomaltase deficiency is estimated to be 1 in 5,000 people of European descent. 0000040856 00000 n You should consult with your physician and registered dietitian to discuss how much starch you can tolerate. The disaccharides activity panel examines tissue samples, which have been taken as part of endoscopy, to gain quantitative values of lactase, sucrase, maltase, palatinase, and glucoamylase. Algorithm for the diagnosis of the most frequent disaccharidase deficiency: lactose malabsorption. Anyone have any experience with any of this? When starting a diet, it is recommended that you use few other spices or seasonings in order to more clearly determine your tolerance levels since many spices contain sugar or starch fillers. Torniainen S, Savilahti E, Jrvel I. Congenital lactase deficiencya more common dis- She can make recommendations for a diet plan that limits disaccharides while incorporating foods you love 3. Carbohydrate malabsorption. 0000010088 00000 n Sucrase deficiency in Green- Clin Chim Acta. They put him on prednisone for a 6 week run including the taper. Learn more about the Merck Manuals and our commitment to Global Medical Knowledge. Gastroenterology. Lactase levels are high in neonates, permitting digestion of milk; in most ethnic groups (80% of blacks and Hispanics, > 90% of Asians), the levels decrease in the post-weaning period rendering older children and adults unable to digest significant amounts of lactose. with failure to thrive, hypercalcemia, and nephrocalcinosis. Approximately 60% to 80% of starch digestion in the small intestine is regulated by the disaccharidase (enzyme), sucrase-isomaltase. Reintroduction. Begin with a complete diary elimination diet that will help you avoid lactose, the sugar and also whey and casein the proteins. Congenital (eg, rare deficiencies of lactase or sucrase-isomaltase), Acquired lactase deficiency (primary adult hypolactasia) is the most common form of carbohydrate intolerance. var g = "dases?cc=MASTER"; You are encouraged to report negative side effects of prescription drugs to the FDA. 1987;22:24-28. The LTT is rarely used since the introduction of breath tests. 1. Epidemiological data demonstrate this condition is more common in certain ethnic groups and geographic locations. Youve read {{metering-count}} of {{metering-total}} articles this month. What causes this disease and how frequent is it? PPTwordPPTwordwordword Congenital Lactase Deficiency Adaptation of intestinal lactase occurred between eight and ten weeks of age in young rats fed a 10% lactose diet. Disaccharidase deficiency: Deficiency of the enzymes in the small intestine that break down disaccharides such as lactose, sucrose and maltose (i.e. %%EOF Trehalase deficiency is less common and presents when mushrooms are ingested. Disaccharides are a type of carbohydrate 23. 0000013611 00000 n In adult onset lastose intolerance, lactase enzyme production starts to decrease as a person matures. We have an update with the doctor next Tuesday to see where we go from here. 1686-94.

Because the test is invasive, many people prefer to try to control the symptoms by dietary methods. <<06E783B5A772D64DBD765FF42D03F1F7>]/Prev 398468/XRefStm 1706>> High-throughput tissue homogenization method and tissue-based o [ pediatric abdominal pain ] Sucraid(sacrosidase) Oral Solution is an enzyme replacement therapy for the treatment of genetically determined sucrase deficiency, which is part of congenital sucrase-isomaltase deficiency (CSID). Most cases are infectious, although gastroenteritis may occur after ingestion of drugs and chemical read more ]). Breakfast cereals or grains that contain whole oats, barley, or bran are better options than more-processed, refined cereals. CSID is an inherited deficiency of the ability to hydrolyze sucrose, maltose, and starch. 2. I appreciate any information you find! The test is not very sensitive and a positive result merely indicates the presence of an unabsorbed sugar in the stool but cannot identify the specific sugar. Carbohydrate intolerance is a malabsorption syndrome Overview of Malabsorption Malabsorption is inadequate assimilation of dietary substances due to defects in digestion, absorption, or transport. Frequently the child is without complaints first thing in the morning, but 1 to 3 hours after ingesting milk or other dairy products develops distension and crampy abdominal pain that is relieved by passing flatus or upon defecation. Dietary restriction is usually adequate treatment. Journal of Pediatrics. Dietary treatment for Congenital Sucrase-Isomaltase Deficiency (CSID) is based on restricting the consumption of sucrose, isomaltose, and maltose. Usually the mother reports watery diarrhoea, generally after the first feeding of breastmilk, but at the latest by age 10 days7. Perman JA. Home Decision Support in Medicine Pediatrics. Also write down the timing of any gastrointestinal symptoms you experience, such as bloating, gas, diarrhea, or abdominal pain. 0000030173 00000 n and are summarized (See Table II.). 0000013437 00000 n Secondary deficiencies of lactase are common and present after depletion of mature enterocytes from an underlying disorder or disease process. 'vFc8L In addition to sugars and fibers, starch is a component of some carbohydrates. Disaccharide intolerance occurs when you don't produce the enzymes sucrase and isomaltase, which are essential for breaking down disaccharides 13. Disaccharidase deficiency Simple Sugars Food Intolerance Carbohydrates Nutrition Diet Health Low Health Care Banting Sucrose Intolerance | GI for Kids, PLLC Dieta Fodmap Ibs Diet Elimination Diet Hypothyroidism Diet Candida Diet Food List Ulcerative Colitis Diet Candida Diet Recipes Dieta Candida Candida Yeast In general, you can consume most fats and oils, such as butter, margarine, olive oil, and vegetable oil, without restriction. Pua Hopson, D.O., discusses Mayo Clinic Labs new disaccharidase activity panel, which measures levels of five digestive enzymes to identify deficiencies that cause carbohydrate maldigestion and can lead to chronic conditions like celiac disease or inflammatory bowel disease. Problems occur when the amount of disaccharide in the food exceeds the capacity of the enzymes to digest it. Incidence and genetic aspects. In some cases, the deficient enzyme can be provided as medication to be consumed with the food or as drops to be added to foods (e.g., lactase in the form of Lactaid or Lacteeze). A disaccharide-restricted diet should be followed for a minimum of 4 weeks to determine if disaccharidase deficiency is the cause of the gastrointestinal symptoms. Usually the intestinal cells are producing a limited amount of enzyme, so that small doses of disaccharides in foods can be processed. It usually presents after weaning from breast milk, when sucrose or starch intake increases. Diarrhoea, abdominal distention, pain, and flatulence (wind) are the usual symptoms of disaccharide intolerance.2 , These symptoms are the result of microbial fermention and a change in osmotic pressure in the large bowel. Started having severe diarrhea & a lot pain for a day (5-25 times in a 12 hour period) this would happen 1 month. It manifests during infancy after the introduction of sucrose in fruits and juices or glucose polymers in infant formula. Disaccharidase deficiency | Oxford Textbook of Medicine | Oxford Academic Skip to Main Content Subject Journals Books Oxford Textbook of Medicine (6 edn) John Firth (ed.) Once the intestinal cells start to heal, you will gradually resume production of the disaccharidase enzymes. However, protein sources such as meats may be cooked with butter, oils, salt, and pepper without triggering CSID-like symptoms. Disaccharidase deficiency J Am Diet Assoc. This material may not be published, broadcast, rewritten or redistributed in any form without prior authorization. Then he would go back to normal for the rest of the time. PMID: 4554577 No abstract available. Starch and sugar components for different varieties of nuts can be found in the food composition tables on this website. Will your som always be on a steroid or is something he starts when a flare up begins? When beginning a diet, you could start with the food items that most individuals with CSID can tolerate and then add other food items over time, as tolerated. If you have CSID, you should plan your diet in conjunction with your physician and registered dietitian. https://testdirectory.questdiagnostics.com/test/test-detail/19701/dis, Do Not Sell/Share My Personal Information. If the infant is allergic to cows milk proteins an extensively hydrolyzed sucrose-free casein formula such as Enfamil Nutramigen (Mead Johnson) and Enfamil Pregestimil (Mead-Johnson) is recommended.. A convenient way to manage disaccharide intolerances is to conduct the diet in three phases:3. Interested in more discussions like this? 1867 0 obj <> endobj Now I am 72 years old. Carbohydrate malabsorption is detected by testing a childs stool and finding a pH less than 5.5, which is caused by carbohydrate fermentation from malabsorption. In: Stanbury JB, Wybgaarden JB, Fredrickson DS, Goldstein JS, Brown MS eds. Structural and functional damage to the intestine and the potential beneficial effects of dexamethasone (Dex) and thyroxine (T4) were examined in zinc-deficient rats. Over time, you may be able to tolerate more dairy products than those listed above. In whites the CC genotype of the SNP -13910 T/C upstream of the lactase gene is associated with adult-type hypolactasia while the TC and TT genotypes are linked with lactase persistence. It is the result of a programmed reduction of lactase synthesis after three years of age and affects approximately half of the worlds population. The starch, which is composed of long chains of glucose molecules, is gradually split into smaller and smaller chains by amylase enzymes. Lactose intolerance is quite different from milk allergy, in which a persons immune system reacts to the protein in milk. For sucrose deficiency, Infants and Children =15 kg: 8500 international units (1 mL) per meal or snack; Children >15 kg and Adults: 17,000 international units (2 mL) per meal or snack. Below are some general dietary guidelines to discuss with your physician or registered dietitian. Any condition such cows milk, soy, fish protein enteropathy (sensitivity) that leads to inflammation in the small intestine and damage to the enzyme-producing cells No sponsor or advertiser has participated in, approved or paid for the content provided by Decision Support in Medicine LLC. But it appears not to be the same for diagnosing lactase deficiency. Tell your doctor if you have diabetes, as your blood glucose levels may change if you begin taking Sucraid. Connect with thousands of patients and caregivers for support and answers. This test can identify a specific unabsorbed sugar in the stool unless it has been fully fermented by the colonic bacterial flora. following a lactose-free diet in cases of lactase deficiency). 0000041425 00000 n The lactose tolerance test is less sensitive, about 75%, although specificity is > 95%. 0000044025 00000 n Avoid eating foods that list these specific types of disaccharides as ingredients 3. This restriction is necessary to determine your sucrose tolerance levels before introducing dietary starches. Processed cheeses and processed cheese products are made from normal cheese, but may include other unfermented dairy ingredients, emulsifiers, extra salt, food colorings, or whey. Nutrition for Special Needs New York: Marcel Dekker; 1985:145-157. Conditions that may trigger a disaccharide intolerance, Intolerance may occur as a result of any condition that causes a decrease in disaccharide enzyme activity:5. Some individuals with CSID are able to tolerate normal amounts of dietary starch, some can eat limited amounts of starch, and some cannot tolerate any dietary starch. (See Some starches are digested more slowly in the small intestine and will slow gastric emptying, the rate at which food moves from the stomach into the small intestine and the rest of the digestive tract. Lactase: Abnormal Range is less than 10 U*, *U, units; activity level may be reported as M/min/g, Nichols B, Adams B, Roach C, Ma C, Baker S. Frequency of sucrase deficiency in mucosal biopsies. 316. Since milk foods are rich in lactose, having milk or other dairy product, may aggravate your digestive tract. Treatment is removal of the causative disaccharide from the diet. His lactase is now zero, all of the other ones are very low as well. N Engl J Med. 0000019264 00000 n Disaccharidases are enzymes that break disaccharides down into monosaccharides for digestion. She said if it is it is an atypical presentation. You can buy all of Dr Joneja's books here or here in the US. The monosaccharides are then absorbed through the gut wall, into blood. Joneja JMV. The smallest carbohydrate units, the monosaccharides, are the building blocks for more complex sugars and starches. If the enzyme deficiency is a result of damage to the intestinal cells, caused by infection, food allergy, food protein enteropathy, or strong drugs, it is called a secondary deficiency and is usually temporary. 0000009875 00000 n Some types of beer are rich in maltose, a type of disaccharide, so you need to eliminate drinking beer. Treatment read more , acute intestinal infections [see Gastroenteritis Overview of Gastroenteritis Gastroenteritis is inflammation of the lining of the stomach and small and large intestines. How should you interpret the results? In experimentally induced diarrhea a fecal pH of <5.3 indicates carbohydrate malabsorption is the major cause of diarrhea. Disaccharidase Deficiency. In infants, temporary secondary disaccharidase deficiency may complicate enteric infections or abdominal surgery. Duodecim. CARBOHYDRATE DIGESTION AND ABSORPTION For dietary carbohydrates to be utilized by the body, they must be converted during digestion to monosaccharides. If there is a deficiency in the enzymes that split these linkages, free glucose molecules will not be released and absorbed, and the remaining undigested starch or sugar will be pass into the large bowel where bacteria ferment it. 0000053945 00000 n land. Lactase deficiency has been observed in 30% to 40% of patients with Crohn's disease. Enzyme supplements should be an adjunct to, not a substitute for, dietary restriction. Symptoms started in Aug 2015, working at a zoo. 0000045274 00000 n Visit www.FDA.gov/medwatch or call 1-800-FDA-1088. o [teenager OR adolescent ], , MD, The Medical City, Pasig City, Philippines. PIP: This review of the literature and current knowledge concerning a nutritional disorder of disaccharidase deficiency discusses the following topics: 1) a description of disorders of disaccharide digestion; 2) some historical perspective on the laboratory and bedside advances in the past 10 years that have helped define a group of these 2002;2:2-4. Coeliac disease that causes damage to the cells lining the small intestine, which include the cells that produce disaccharidase enzymes For lactase deficiency, 1-2 capsules taken with milk or dairy products; pre-treat milk with 1-2 capsules/quart of milk; Liquid: 5-15 drops/quart of milk; Tablet: 1-3 tablets with meals. Lactose and sucrose are the most common disaccharides in the diet. Thank you for any help you can provide. Here's what you can expect at your child's first visit. 1998. pp. In the case of lactose intolerance there are two types of primary deficiency: Congenital (discussed above) and adult onset lactose intolerance. This enzyme complex (sucrase-isomaltase) assists in the breakdown of a certain sugars (i.e., sucrose) and certain products of starch digestion (dextrins). patients. Nuts and nut butters can be a great source of calories for you. You should also avoid processed meats such as bacon, sausage, luncheon meat, deli meat, liverwurst, and pt since many of these food items are cured with sucrose or have starch fillers. 0000028403 00000 n Congenital or primary disaccharidase deficiencies require life-long management. o [ abdominal pain pediatric ] Gastroenterology. Meats and Other Sources of Protein In general, most individuals with CSID can eat plain sources of protein, including beef, pork, lamb, fish, turkey, chicken, and eggs. Congenital sucrase-isomaltase deficiency (CSID) is a rare inherited metabolic disorder characterized by the deficiency or absence of the enzymes sucrase and isomaltase. Lactose restricted: calcium and vitamin D If lactose is ingested with high fat meal the symptoms may be less severe due to slower gastric emptying. Lactose and other disaccharides intolerances - Dr Janice Joneja. Lloyd-Still JD, Listernick R, Buentello G. Complex carbohydrate intolerance: diagnostic Twenty to 40% is regulated by the disaccharidase (enzyme), maltase-glucoamylase. What complications might you expect from the disease or treatment of the disease? For this reason, it is recommended that you monitor consumption of these vegetables closely. et al. CCFA.org a lot of information is available. Faith. We are so ready for answers as this has pretty much taken over our lives. (Yogurt a well-tolerated source of milk for lactase-deficient persons. vol. This doesnt mean that will help your son but be aware that Crohns starts at 14 years old typically. Because the small intestine and large intestine are getting smaller amounts of starch at any given time, you may be better able to tolerate the dietary starch. 0000020664 00000 n A small number of individuals do not produce hydrogen or methane and hence will give a false negative result. However, this cure is not always possible as there are many hidden sources of these sugars in foods and medications. 0000001706 00000 n Sucrose tolerance is determined by consuming vegetables, fruits, nuts, seeds, and refined sugars and syrups. 1. The most frequent cause of mucosal damage is celiac disease that can affect 1% of the population. and response to an exclusion diet are the diagnostic procedures for lactase deficiency. // Leaf Group Lifestyle, Signs & Symptoms of Problems Digesting Sugar, Lactose Monohydrate & Lactose Intolerance, University of Massachusetts: Analysis of Carbohydrates, but they contain starch which is a type of polysaccharide. However, if there is a deficiency in the production of the enzymes, the disaccharides remain undigested and move into the large bowel intact where they are fermented by the resident microorganisms resulting in the common symptoms of gas production causing abdominal bloating, pressure, pain, wind and diarrhoea. However, this is a non specific finding and hence imaging studies have no role in the diagnosis of disaccharidase deficiencies. Similarly, maintenance of appropriate nutrition during and after infectious gastroenteritis has been shown to minimize prolonged mucosal damage. Starchy vegetables, such as: potatoes corn peas are high in carbohydrates Most affected patients have an increase in expired hydrogen of > 20 parts per million over baseline.

Unabsorbed sugars can be detected in the stool. After doing bit of research, heres what I found: Disaccharidases are enzymes that break down complex sugars (like lactose) into simple sugars (like glucose) so that the intestine can absorb the nutrients. A registered dietitian can assist you in using a food log and determining food tolerances. Thats a pretty standard dose of Prednisone for a flare, and the Apriso may help for maintaining some remission over time. 1984. pp. All Rights Reserved. Undigested disaccharides cause an osmotic load that attracts water and electrolytes into the bowel, causing watery diarrhea. "Hello @fa7100, I'm so sorry to hear about your son; it must be terrible to watch", "Yes I had similar problems when I was 14 years old and at 15 years old", "That's great news to hear. Most contain negligible amounts of lactose and are tolerated by most lactose-intolerant individuals. 1995-2023 Mayo Foundation for Medical Education and Research. An affected adult may have watery diarrhea, bloating, excessive flatus, nausea, borborygmi, and abdominal cramps after ingesting lactose. It has been noted that some individuals with CSID are able to increase their starch tolerance as they age and their digestive tract grows longer. vol. 0000037251 00000 n The disaccharides are then split into their two monosaccharide (single sugar) components by special disaccharidase enzymes in the cells lining the small intestine. Diet Diet Therapy Ethnic Groups Food Supply Galactosidases / metabolism* . Primary lactase deficiency is due to a genetically programmed gradual loss of intestinal lactase production that occurs after the early childhood in affected individuals. Philadelphia, PA 19104, Know My Rights About Surprise Medical Bills, Division of Gastroenterology, Hepatology and Nutrition, 2022 The Childrens Hospital of Philadelphia. Diagnosis read more ). All 5 disaccharides were low (like half of what they should be). In summary, most food items made with refined and processed flour may be difficult for you to consume without developing gastrointestinal symptoms. There was a good correlation between the C/C(-13910) genotype and low lactase activity (<10 U/g protein) in the majority of children tested at 8 years of age and in every child older than 12 years of age, giving a specificity of 100% and sensitivity of 93% for the genetic test. The diet should include salmon, baked beans, spinach, leafy vegetables, shrimp, green peas, oysters, broccoli and fresh fruits. Except in the case of a lactase deficiency, which improves dramatically when lactose is removed from the diet, it is often difficult to separate specific disaccharide intolerances from each other. The osmotic gap is best determined by measuring the stool electrolytes and using the calculation gap= 290- 2x(Stool Na. Childrens Hospital of Philadelphia is a charitable 501(c)(3) nonprofit organization. Sensitivity is 78% and specificity is > 95% (1 Diagnosis reference Carbohydrate intolerance is the inability to digest certain carbohydrates due to a lack of one or more intestinal enzymes. Tell your doctor if you are allergic to, have ever had a reaction to, or have ever had difficulty taking yeast, yeast products, papain, or glycerin (glycerol). This type of deficiency cannot be prevented. Yes I had similar problems when I was 14 years old and at 15 years old I was diagnosed with inflammation causing severe pain and they were going to remove part of my intestines. Sucrose is usually derived from sugar beet or sugar cane but is also found in many fruits and some grains and vegetables.
