[Irritable colon]

Irritable Bowel Syndrome (IBS) is a common functional gastrointestinal disorder, defined as a variable combination of chronic or recurrent gastrointestinal symptoms not explained by structural or biochemical abnormalities. It is attributable to the intestine with symptoms of abdominal pain, altered bowel habits and bloating. The diagnosis is primarily based on typical symptoms and prudent use of investigations to exclude organic disorders. The initial positive diagnosis is accurate and on a longterm follow-up its revision rarely required. A change in its clinical manifestation may imply the superimposition of another disorder. Treatment primarily rely on the confidence in the diagnosis and a strong physician-patient relationship. High fiber diets and bulking agents may be effective in alleviating symptoms. Though antispasmodic, antidiarrheal and psychotropic drugs are repeatedly used in patients with moderate to severe symptoms their effects remain uncertain. Psychotherapy, hypnosis and biofeedback may relief symptoms and may be considered for motivated patients with moderate to severe symptoms.
