How to Medicate for IBS

Irritable bowel syndrome or IBS affects the colon. It causes cramps, gas, bloating, stomach pain, diarrhea and constipation. Make an appointment with a doctor if any of the symptoms are present. The cause of IBS is unknown, and treatment focuses more on the relief of symptoms. Mild cases may be controlled by managing stress and making dietary changes. Medications may be prescribed for acute IBS.
