What is malabsorption?
Malabsorption is a broad term used to describe the inability to absorb nutrients through the gut lining into the bloodstream. The impaired absorption by the intestines of nutrients from food. Malabsorption is not a disease by itself, but rather the result of some other condition that is present. The small intestine (also called the small bowel) is typically involved in
malabsorption, since the majority of nutrients are absorbed there. Malabsorption may affect one or more of the many nutrients present in the diet, including protein, fat, carbohydrate, vitamins, and minerals.
Malabsorption means the failure of the GI tract, usually the small intestine, to absorb one or more substances from the diet. This is generally the result of some defect or damage to the mucosal lining of the small intestine where most of our nutrient absorption takes place. The most common symptoms of malabsorption syndrome are diarrhea, bloating, flatulence, cramping and weight loss. Over time, one may become deficient in iron, proteins, various vitamins and minerals and this can lead to degrees of malnutrition and a variety of anemias.
The most common anemias that may occur are vitamin B12, folate, and iron deficiency. Vitamin K malabsorption causes the blood to thin out and could result in excess bleeding. Protein depletion can lead to impaired bone formation and osteoporosis, and calcium deficiency leads to weakening and demineralization of the bone, causing a condition called osteomalacia. Impaired absorption of vitamin A could result in poor vision and night blindness as well as dermatitis. Malabsorption of protein, fat and carbohydrate leads to loss of calories, generalized malnutrition and diarrhea.
Normally, foods are digested and nutrients are absorbed into the bloodstream mainly in the small intestine. Malabsorption may occur if a disorder interferes with the digestion of food or if a disorder interferes directly with the absorption of nutrients. Digestion can be affected by disorders that prevent adequate mixing of food with digestive enzymes and acid from the stomach. Inadequate mixing may occur in a person who has had part of the stomach surgically removed. In some disorders, the body produces inadequate amounts or types of digestive enzymes, which are necessary for the breakdown of food. For example, a common cause of malabsorption is insufficient production of digestive enzymes by the pancreas, as occurs with some pancreatic diseases, or by the small intestine, as occurs in lactase deficiency. Decreased production of bile, too much acid in the stomach, or too many of the wrong kinds of bacteria growing in the small intestine may also interfere with digestion.
More information on malabsorption (celiac disease, lactose intolerance, Whipple's disease)
What is malabsorption? - Malabsorption is the inability to absorb nutrients through the gut lining into the bloodstream. Malabsorption is the failure of the GI tract to absorb one or more substances from the diet.
What causes malabsorption? - The causes of malabsorption include cystic fibrosis, lactose intolerance, celiac disease, Whipple disease, acrodermatitis enteropathica, biliary atresia, pernicious anemia.
What are the symptoms of malabsorption? - The signs and symptoms of malabsorption may include failure to thrive, diarrhea, cramping, frequent bulky stools, bloating, flatulence, and abdominal distention.
How is malabsorption diagnosed? - The diagnosis of malabsorption syndrome and identification of the underlying cause can require extensive diagnostic testing.
What's the treatment for malabsorption? - Treatment of malabsorption is the treatment of the causing disease. Fluid and nutrient monitoring and replacement is essential for individual with malabsorption syndrome.
What is celiac disease? - Celiac disease is a sensitivity to gluten, a wheat protein. Individuals with this disease must avoid gluten-containing grains, which include all forms of wheat, oats, barley, and rye.
What is gluten? - Gluten is a protein in grains such as wheat, oats, rye, and barley. Gluten is responsible for the elasticity of kneaded dough which allows it to be leavened.
What causes celiac disease? - The exact cause of celiac disease is not known. The principal cause of the disorder is an immunologic reaction to components of certain dietary glutens.
What are the symptoms of celiac disease? - The symptoms of celiac disease (CD) vary so widely among patients that there is no such thing as a typical celiac. Symptoms may or may not occur in the digestive system.
How is celiac disease diagnosed? - Celiac disease may be diagnosed by observing the symptoms after an infant begins eating cereals. The diagnosis is suspected when a person has the above-mentioned symptoms.
What are the treatments for celiac disease? - Many of the effects of celiac disease can be treated and minimized with a special diet. People with celiac disease learn to avoid the proteins in cereal.
Celiac disease and gluten-free diet - A gluten-free diet is a diet completely free of ingredients derived from gluten containing cereals, wheat, oats, barley and rye.
What is lactose intolerance? - Lactose intolerance is a set of symptoms resulting from the body's inability to digest the milk sugar called lactose. Lactose is sugar occuring naturally in milk and is also called milk sugar.
What causes lactose intolerance? - Primary lactase deficiency is a genetically inherited. Secondary lactase deficiency is a transient state of lactase deficiency due to damage to the lining of the intestine.
What are the symptoms of lactose intolerance? - People with lactose intolerance usually cannot tolerate milk and other dairy products. The symptoms of lactose intolerance are dose-dependent.
How is lactose intolerance diagnosed? - Lactose intolerance is widely regarded as a medical condition. The most common test for lactose intolerance is the hydrogen breath test.
What's the treatment for lactose intolerance? - Lactose intolerance can be controlled and treated through diet by avoiding foods containing lactose, primarily dairy products.
Manage lactose intolerance with lactose-free diet - People who are very sensitive to lactose should be aware that lactose is widely used as an ingredient in many ready-made meals and other food products.
What is Whipple's disease? - Whipple's disease is a malabsorption disease. It interferes with the body's ability to absorb certain nutrients.
What causes Whipple's disease? - Whipple's disease is caused by the organism Tropheryma whippelii. The disease causes lesions on the wall of the small intestine and thickening of the tissue.
What are the symptoms of Whipple's disease? - Whipple's disease causes weight loss, irregular breakdown of carbohydrates and fats, resistance to insulin, and malfunctions of the immune system.
How is Whipple's disease diagnosed? - Whipple's disease is diagnosed through a tissue sample (biopsy) of the small intestine, or of an enlarged lymph node.
What is the treatment for Whipple's disease? - Whipple's disease is treated with antibiotics to destroy the bacteria that cause the disease, treatment may also include fluid and electrolyte replacement.
