Irritable bowel syndrome (IBS) is a disorder of the intestines that causes abdominal discomfort, bloating, gas, and changes in bowel habits. It is defined as recurrent abdominal pain related to defecation, associated with a change in frequency of stool, associated with a change in form of stool. It is estimated that 10 to 20% of adults have IBS. Women are more likely to suffer from this disorder.

Physicians refer to IBS as a functional disorder that may be due to hypersensitivity of the gut, spasticity, or dysbiosis (microbial imbalance). While there is discomfort or pain, it does not lead to life threatening harm.

Symptoms:

• Abdominal pain or cramping
• Bloating
• Gas
• Constipation or diarrhea (or alternating between constipation and diarrhea)

Symptoms and signs NOT associated with IBS and considered alarm features include, but are not limited to:

• Bleeding
• Nocturnal (nighttime) symptoms
• Weight loss
• Anemia
