Irritable bowel syndrome (IBS) or irritable bowel disease (IBD), is also known as spastic colitis, mucus colitis, and nervous colon. It is a chronic, or long-term, condition, but symptoms tend to change over the years. It’s not uncommon for people with IBS to have episodes of both constipation and diarrhea. Symptoms such as bloating and gas typically go away after a bowel movement. There is no cure for IBS. Treatment is aimed at symptom relief. Certain foods as well as stress and anxiety can be triggers for IBS symptoms for many people. Medications are available to ease the symptoms of IBS, but some patients feel better trying natural remedies instead of (or in addition to) conventional drugs.
