Digestive health

Common digestive disorders


Gastritis is a term used to describe inflammation of the mucosa (lining) of the stomach.

Crohn's disease

Crohn's disease is a chronic disorder that causes inflammation of the gastrointestinal tract, resulting in diarrhoea, or frequent, loose, watery stools.

Celiac disease

Celiac disease, also called celiac sprue, is a digestive disorder that occurs when an individual's immune system overreacts to the protein gluten, or other proteins within gluten such as gliadin, found in grains including wheat, rye, barley, and to some degree, oats. When a patient with the disease eats food that contains gluten, the immune system's response damages the intestinal lining. This causes symptoms of abdominal pain and bloating after consuming gluten.

Gastrointestinal disorders

Gastroinestinal disorders occur when the digestive tract (gastrointestinal) does not function properly. As a result, patients may have difficulty digesting food, absorbing nutrients, or having normal bowel movements.
