Medical conditions that accompany IBS

Researchers have identified several medical conditions, or comorbidities, which appear with greater frequency in patients diagnosed with IBS.

Headache, Fibromyalgia, and Depression: A study of 97,593 individuals with IBS identified comorbidities as headache, fibromyalgia, and depression. Fibromyalgia has also been identified in other studies as a comorbidity of IBS.

Inflammatory bowel disease: Some researchers have suggested that IBS is a type of low-grade inflammatory bowel disease. Researchers have suggested that IBS and IBD are interrelated diseases, noting that patients with IBD experience IBS-like symptoms when their IBD is in remission. A 3-year study found that patients diagnosed with IBS were 16.3 times more likely to develop IBD during the study period. Serum markers associated with inflammation have also been found in patients with IBS

Abdominal surgery: A recent (2008) study found that IBS patients are at increased risk of having unnecessary cholecystectomy (gall bladder removal surgery) not due to an increased risk of gallstones, but rather to abdominal pain, awareness of having gallstones, and inappropriate surgical indications. A 2005 study published in Digestive Disease Science reported that IBS patients are 87% more likely to undergo abdominal and pelvic surgery, and three times more likely to undergo gallbladder surgery. A study published in Gastroenterology came to similar conclusions, and also noted IBS patients were twice as likely to undergo hysterectomy.

Endometriosis: One study has reported a statistically significant link between migraine headaches, IBS, and endometriosis.

Other chronic disorders: Interstitial cystitis may be associated with other chronic pain syndromes, such as irritable bowel syndrome and fibromyalgia. The connection between these syndromes is unknown.
