Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) is a common condition that includes a group of unpleasant symptoms that may occur often but do not cause damage to the intestines.

The three types of IBS are grouped by the main bowel problem experienced:

  • IBS-D (diarrhea)
  • IBS-C (constipation)
  • IBS-M (mixed), also called IBS-A (alternating) – alternating diarrhea and constipation

Symptoms usually include abdominal pain, bloating, or cramping, plus:

  • Diarrhea
  • Constipation
  • Alternating diarrhea and constipation

Even though the symptoms do not cause damage to the intestines, they can cause a lot of pain, stress, and anxiety. Some people may experience a fear of eating, or avoidance of food in certain situations, which can lead to nutritional deficiencies. Too much diarrhea can cause dehydration, and IBS can also interfere with a person’s ability to work, travel, and socialize.

Manage your IBS by:

  • Keeping a log of your diet and symptoms to help identify foods that cause problems.
  • Avoiding caffeine, nicotine, and foods high in fat and sugar.
  • Making an effort to decrease stress in your life and learning how to better cope with stress you cannot avoid.
  • Increasing physical activity in ways that are comfortable for you. This can also help relieve stress.
  • Avoiding overeating. Even “safe” foods can cause problems for those with IBS when consumed in large amounts.
