Causes & Risk factors
It is exactly not known what the cause of the disease is. In this disorder, the intestines which normally are lined with a thin layer of muscle contract and relax through the intestinal tract to the rectum. The contractions in the syndrome may be stronger and lasting longer than normal. Sometimes, the food is forced through the intestines more quickly, causing gas, bloating and diarrhoea.
The trigger for the irritable bowel syndrome may be gas, pressure or certain foods, medications or emotions.
- Food- During intake of certain food, some people may have signs and symptoms may worsen. For example, chocolate, milk and alcohol may cause constipation and diarrhoea. Carbonated beverages, fruits and vegetables may be bloating and there may be discomfort in some people with IBS.
- Stress- The symptoms of the disease become worse or more frequent during stressful events such as the change in the daily routine. Stress may aggravate symptoms but doesn’t cause them.
