Irritable bowel syndrome

Irritable bowel syndrome - aftercare

IBS; Mucus colitis; IBS-D; IBS-C

Irritable bowel syndrome (IBS) is a disorder that leads to abdominal pain and bowel changes. Your health care provider will talk about things you can do at home to manage your condition.

I Would Like to Learn About:

What to Expect at Home

Irritable bowel syndrome (IBS) may be a lifelong condition. You may be suffering from cramping and loose stools, diarrhea, constipation, or some combination of these symptoms.

For some people, IBS symptoms may interfere with work, travel, and attending social events. But taking medicines and making lifestyle changes can help you manage your symptoms.

Diet

Changes in your diet may be helpful. However, IBS varies from person to person. So the same changes may not work for everyone.

Keep track of your symptoms and the foods you are eating. This will help you look for a pattern of foods that may make your symptoms worse.
Avoid foods that cause symptoms. These may include fatty or fried foods, dairy products, caffeine, sodas, alcohol, chocolate, and grains such as wheat, rye, and barley.
Eat 4 to 5 smaller meals a day, rather than 3 larger ones.

Increase the fiber in your diet to relieve symptoms of constipation. Fiber is found in whole grain breads and cereals, beans, fruits, and vegetables. Since fiber may cause gas, it is best to add these foods to your diet slowly.

Medicines

No one medicine will work for everyone. Some medicines are prescribed specifically for IBS with diarrhea (IBS-D) or IBS with constipation (IBS-C). Medicines your provider may have you try include:

Antispasmodic medicines that you take before eating to control colon muscle spasms and abdominal cramping
Antidiarrheal medicines such as loperamide
Eluxadoline and Alosetron for IBS-D
Laxatives, such as MiraLAX, bisacodyl, and other ones bought without a prescription for IBS-C
Novel agents to treat constipation such as lubiprostone, linaclotide, plecanatide
Antidepressants (tricyclic and selective serotonin reuptake inhibitor [SSRI] classes) to help relieve pain or discomfort
Rifaximin, an antibiotic that is not absorbed from your intestines
Probiotics

It is very important to follow your provider's instructions when using medicines for IBS. Taking different medicines or not taking medicines the way you have been advised can lead to more problems.

Stress

Stress may cause your intestines to be more sensitive and contract more. Many things can cause stress, including:

Not being able to do activities because of your pain
Changes or problems at work or at home
A busy schedule
Spending too much time alone
Having other medical problems

A first step toward reducing your stress is to figure out what makes you feel stressed.

Look at the things in your life that cause you the most worry.
Keep a diary of the experiences and thoughts that seem to be related to your anxiety and see if you can make changes to these situations.
Reach out to other people.
Find someone you trust (such as a friend, family member, neighbor, or clergy member) who will listen to you. Often, just talking to someone helps relieve anxiety and stress.

When to Call the Doctor

Contact your provider if:

You develop a fever
You have gastrointestinal bleeding
You have bad pain that does not go away
You lose over 5 to 10 pounds (2 to 4.5 kilograms) when you are not trying to lose weight
