Anxiety does not cause IBS, but it may worsen a person’s symptoms. Similarly, a person may experience anxiety-related IBS.
While seemingly unrelated, IBS and anxiety may share a link. Some evidence suggests that the two conditions share similar genetic pathways.
Other evidence suggests that the two conditions often occur together and may worsen each other’s symptoms.
This article reviews the potential links between IBS and anxiety, common symptoms, other possible causes, and more.
IBS and anxiety may share a similar genetic link, according to a
In reviewing the diagnoses of 53,000 people with IBS, researchers found that IBS and anxiety and mood disorders share similar genetic pathways and risk factors, which could explain why they often occur together.
They also noted that increasing abdominal symptom severity often correlated with increasing severity of anxiety symptoms.
Experts often describe anxiety and IBS as creating a “vicious cycle” where each one worsens the others. For example, a person may fear going out to eat with friends, fearing an “attack,” which causes them to experience worsening anxiety and symptoms of IBS.
A person with IBS may want to talk with a healthcare professional if they experience fear, worry, or similar feelings related to their IBS symptoms. They may be able to provide additional treatment options or recommend additional specialists to speak with.
IBS describes several symptoms related to each other. The two most common symptoms associated with IBS include pain in the abdomen, typically starting before, during, or after a bowel movement, and changes to a bowel movement.
- IBS with constipation (IBS-C): IBS-C refers to pain combined with constipation.
- IBS with diarrhea (IBS-D): IBS-D refers to pain combined with diarrhea.
- IBS with mixed bowel habits (IBS-M): IBS-M refers to pain combined with diarrhea and constipation.
Symptoms may vary depending on the person and the exact underlying disorder.
