Topic: Food intolerance, Malabsorption

1. Fact Sheet: Malabsorption

   119

   By: Nimish Vakil, MD, FACP, FACG; Carol Jorgensen-Vakil, MS, RD, CNSD, Registered Dietician

   The gastrointestinal tract and liver play key roles in the digestion, absorption and metabolism of nutrients. Diseases of the gastrointestinal tract and liver may profoundly disturb normal nutrition. Malabsorption refers to decreased intestinal absorption of carbohydrate, protein, fat, minerals or vitamins. There are many symptoms associated with malabsorption. Weight loss, diarrhea, greasy stools (due to high fat content), abdominal bloating and gas are suggestive of malabsorption.

2. Fact Sheet: Lactose Intolerance: Definition, Symptoms and Treatment

   122

   By: Eli D. Ehrenpreis, MD; Benjamin Z. Ehrenpreis

   The term lactose intolerance refers to the development of gastrointestinal symptoms following the ingestion of milk or dairy products. Lactose intolerance is caused by a shortage of a digestive enzyme called lactase, which is produced within the lining of the small intestine, although not all people with lactase deficiency develop symptoms. Lactose intolerance is an extremely common disorder and may have a prevalence of up to 100% in some populations. The following brief review of lactose intolerance will provide a summary of the populations most affected, symptoms, diagnosis, and treatment. Revised 2007.

   By: Kenneth W. Heaton, MD, FRCP

   The exact nature of the connection between what people eat and how their intestines behave is controversial, but there is certainly a connection. The effects of foods on the gut are reviewed.

5. Fact Sheet: Dietary Factors in Gastrointestinal Diseases

   148

   By: Jarol Boan, MD, MPH (formerly Knowles)

   The gastrointestinal (GI) complaints commonly associated with reactions to food include dyspepsia, heartburn, bloating, excessive gas, diarrhea, and constipation. The exact dietary factors that contribute to these symptoms in functional GI disorders, such as IBS, are poorly understood. Clearly, there is a need for more research to examine the relationship between food intake and functional GI symptoms. However, a substantial amount of research has been done to determine the relationship between food and other digestive diseases. This article will examine five such diseases that affect the GI system – gastroesophageal reflux disease (GERD), celiac disease, food allergies, lactose intolerance, and eosinophilic gastroenteritis.

7. Fact Sheet: Dietary Aspects of Irritable Bowel Syndrome (IBS)

   220

   By: Peter J. Whorwell, MD

   Many patients with irritable bowel syndrome (IBS) comment that their symptoms appear to deteriorate following a meal. In many individuals this is merely a nuisance but in others it can be much more of a problem. Fortunately, it is usually reasonably easy to tackle the dietary aspects of IBS as long as you understand a few basic principles. For those who suspect food is a factor in their symptoms, there are 4 foods that most often seem to be involved.
