Coeliac disease – Signs and symptoms

Severe coeliac disease leads to the characteristic symptoms of pale, loose and greasy stool (steatorrhoea), weight loss or failure to gain weight (in young children). People with milder coeliac disease may have symptoms that are much more subtle and occur in other organs rather than the bowel itself. Finally, it is possible to have coeliac [...]

Irritable bowel syndrome – Diagnosis

There is no specific laboratory or imaging test that can be performed to diagnose irritable bowel syndrome. Diagnosis of IBS involves excluding conditions that produce IBS-like symptoms, and then following a procedure to categorize the patient’s symptoms. Ruling out parasitic infections, lactose intolerance, small intestinal bacterial overgrowth and celiac disease is recommended for all patients [...]

Coeliac disease – Pathophysiology

Coeliac disease appears to be polyfactorial, both in that more than one genetic factor can cause the disease and that more than one factor is necessary for the disease to manifest in a patient. Almost all coeliac patients have the variant HLA-DQ2 allele. However, about 20–30% of people without coeliac disease have inherited an HLA-DQ2 [...]

Food intolerance – Diagnosis

Diagnosis of food intolerance can include hydrogen breath testing for lactose intolerance and fructose malabsorption, professionally supervised elimination diets, and ELISA testing for IgG-mediated immune responses to specific foods. It is important to be able to distinguish between food allergy, food intolerance, and autoimmune disease in the management of these disorders. Non-IgE-mediated intolerance is more [...]

Diarrhea – Differential diagnosis

Ascites is the proper medical term for abdominal bloating caused by excessive accumulation of liquid inside the cavity.

Irritable bowel syndrome – Management

A number of treatments have been found to be better than placebo, including fiber, antispasmodics, and peppermint oil. Diet Some people with IBS are likely to have food intolerances. In 2007 the evidence base was not strong enough to recommend restrictive diets. Many different dietary modifications have been attempted to improve the symptoms of IBS. [...]

Oral allergy syndrome – Diagnosis

Elimination Diet

The patient typically already has a history of atopy and an atopic family history. Eczema, otolaryngeal symptoms of hay fever or asthma will often dominate leading to the food allergy being unsuspected. Often well-cooked, canned, pasteurized or frozen food offenders cause little to no reaction due to denaturation of the cross-reacting proteins, causing delay and [...]

Diarrhea – Definition

Diarrhea

Diarrhea is defined by the World Health Organization as having 3 or more loose or liquid stools per day, or as having more stools than is normal for that person. Secretory Secretory diarrhea means that there is an increase in the active secretion, or there is an inhibition of absorption. There is little to no [...]
