As far as scientists know, irritable bowel syndrome doesn’t cause depression, and depression doesn’t cause IBS. But for many people, the two go together. Sometimes, one condition can make the other one worse. It can be a frustrating cycle.
At the same time, treatments that usually relieve the mood disorder can help some people with their IBS symptoms, too. They can give you even more options to consider when you’re looking for relief.
How IBS and Depression Work Together
The symptoms of irritable bowel syndrome can cause a level of distress that looks like depression. Some people are so worried that their diarrhea, constipation, or other symptoms will flare up that they avoid going to work, school, or out with friends. They may focus less on their social lives and lose interest in activities they once enjoyed. They may feel restless or irritable. All of these are symptoms of depression.
On the other hand, the mood disorder may influence the way people handle IBS. They may feel too tired or hopeless to bother changing their diet to ease digestive symptoms or think they can’t treat their constipation or diarrhea well enough. Also, emotional stress makes bowel symptoms worse.
