Irritable bowel syndrome, or IBS, is a fairly common intestinal complaint. If you’ve been dealing with abdominal pain, diarrhea, constipation, cramping, bloating, or excessive gas, you might be one of the twenty percent of the population that suffers from IBS. Women are more likely to experience this condition than men, and it is more likely to surface among those who are under age 50. Other risk factors include having a mental illness, or having a family history of IBS.
