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.
Irritable bowel syndrome (IBS) is especially hard on people at work, but there are ways to cope.
Even getting ready to go to work can be hard for people with some types of IBS. It's not unusual for IBS sufferers to have four to five bowel movements before they leave the house, says Jeffrey Roberts, president and founder of the IBS Self Help and Support Group. The group has 60,000 active members online, as well as face-to-face meetings in the U.S., Canada, and other countries.

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.
Antidepressants for IBS
Some depression meds can treat the mood disorder and some of the symptoms of IBS. But they're used in different ways for each condition, so it's important to talk with your doctor to learn how you should take them.
Even people with irritable bowel syndrome who aren’t depressed can get relief from antidepressants. The drugs can help block how the brain processes pain.
The American College of Gastroenterology says two types of antidepressants can help IBS symptoms:
Tricyclic antidepressants, like amitriptyline (Elavil, Vanatrip), desipramine (Norpramin), or nortriptyline (Pamelor)
Selective serotonin reuptake inhibitors (SSRIs), like citalopram (Celexa), paroxetine (Paxil), or sertraline (Zoloft)
But experts say they need more research to fully understand how safe and effective the drugs are for people with IBS.
