People living with Crohn’s may experience periods of flares and remission. During remission, Crohn’s symptoms may reduce or resolve completely. Remission can last months or even years in some people.

Crohn’s disease is a chronic inflammatory bowel disease. Those living with the condition will experience periods of flares in which their symptoms are active as well as periods of remission when symptoms are reduced or go away completely.

There are many types of remission in Crohn’s, and it is possible to be in one form of remission but not another.

Being in remission from Crohn’s generally means that symptoms are well managed. Some people may not notice any symptoms at all when in remission, while some may experience a decrease in their symptoms.

The term “remission” can mean different things. People may find it beneficial to clarify with their healthcare professional what form of remission they are referring to.

It is possible to be in one form of remission but not another. For example, a person may be in clinical remission but not in endoscopic remission.

Here are the types of remission a doctor typically refers to:


Clinical remission refers to having no symptoms of Crohn’s.


A biochemical remission refers to not having markers in blood or stool samples that may be indicative of active disease.

The biomarkers often used to determine disease activity in Crohn’s are C-reactive protein (CRP) and fecal calprotectin.


Endoscopic remission may also be referred to as mucosal healing. This form of remission refers to a person not having any noticeable mucosal ulceration in the area that is examined during a procedure like a colonoscopy.


Histology is the study of tissues and organs under a microscope.

Even if a person with Crohn’s is in clinical or endoscopic remission, it is still possible to have microscopic disease activity.

Being in histologic remission means not showing signs of active disease, such as inflammation, at this microscopic level.

Deep remission

This refers to a person experiencing no symptoms of Crohn’s, and no inflammation is seen during an endoscopy.


Between 66 and 75% of people with Crohn’s will need to undergo surgery to effectively manage their disease.

Surgery can lead to remission in some people. The process is referred to as surgical remission or surgically induced remission.

Medical treatment for Crohn’s can bring the disease into remission as well as help maintain remission.

Treatments that may induce remission or help maintain remission include:

  • aminosalicylates
  • corticosteroids
  • immunomodulators
  • biologic therapies
  • antibiotics
  • surgery

Properly adhering to prescribed treatments is an important factor to inducing and maintaining remission.

In addition to adhering to prescribed treatments, there are other factors that can influence whether a person is in remission or experiencing a symptom flare-up.

These factors may include:

  • experiencing stress
  • smoking
  • using antibiotics
  • using nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen

People living with Crohn’s will typically experience periods of active disease, or flares, and periods of remission.

During a flare, a person may experience more Crohn’s symptoms, such as diarrhea, abdominal pain, and frequent bowel movements.

If a person is in remission, they may find their symptoms either decrease or disappear completely. Some people may find that common symptoms like diarrhea and abdominal pain are no longer present. They may also feel quite healthy during a period of remission.

Some people may still experience symptoms during remission, though symptoms may not be as severe as during a flare.

Some people may stay in remission for months or even years, but flare-ups can still occur. There are steps a person can take that can help reduce the chances of this happening.

Continue taking prescribed medications

Even if symptoms improve or disappear completely, it is important to continue taking the medications your healthcare professional prescribed for Crohn’s and follow their instructions.

These “maintenance” medications can help reduce the chances of a flare.

Pay attention to diet

There is no specific eating plan for Crohn’s, but the food you eat can help promote healing as well as reduce symptoms.

Every person living with Crohn’s will experience the disease differently. The intestinal area the disease affects may determine which foods work best.

A doctor may suggest a variety of eating plans based on symptoms and disease activity. They may include:

  • low fat diet
  • low salt diet
  • low fiber diet
  • lactose-free diet
  • high calorie diet

Some people with Crohn’s may find certain foods make their symptoms worse. For example, some people may need to limit or avoid high fiber foods like raw vegetables, nuts, and seeds.

Other steps to consider that may help reduce symptoms include:

  • limiting greasy or fried foods
  • eating smaller portions more regularly
  • experimenting with eating bland, soft foods instead of spicy foods (though this may not help everyone)
  • avoiding carbonated beverages if gas is an issue

Avoid smoking

Smoking can trigger a flare and bring a person out of remission. Those with Crohn’s who smoke tend to have greater disease activity and require more surgeries and medications to effectively manage their condition.

In contrast, those with Crohn’s who do not smoke typically have fewer flare-ups and less need for medications to manage their condition.

Limit alcohol

Drinking alcohol can worsen Crohn’s symptoms. Consuming alcohol — whether moderately or excessively — can contribute to flares.

For people living with Crohn’s, experts advise moderate alcohol consumption if they choose to drink.

Reduce stress

While stress does not cause Crohn’s, highly stressful situations can affect symptoms.

Stress management techniques may be helpful for some people. These may include:

  • breathing exercises
  • yoga
  • meditation
  • cognitive behavioral therapy

It is difficult to predict how Crohn’s may affect a person. Flare-up occurrence can vary widely throughout a person’s life.

In people who receive surgical or medical treatment for Crohn’s, almost 50% will either be in remission or experience a mild condition over the following 5 years.

Of those who are in remission, 45% will stay in remission in the following year.

Of the people who were in remission following surgery or medical treatment, 35% will experience one or two relapses of their disease, and 11% will experience chronically active Crohn’s.

Once a person with Crohn’s goes into remission, the relapse rate at their 1-year remission is 20%, at their two-year remission is 40%, at their 5-year remission is 67%, and at their 10-year remission is 76%.

It is typical for people with Crohn’s not only to experience periods of remission but also to experience relapses and flares.

Flares may be caused by:

  • inflammation in the intestine
  • scar tissue
  • infection
  • side effects of medication
  • lifestyle factors like eating patterns and stress
  • not taking medications correctly

If a flare occurs, it is important to speak with a doctor. They can help determine what is causing the flare and, if necessary, adjust treatment plans.

Flares may cause more severe symptoms. Here are some suggestive ways to help manage them:

  • taking over-the-counter and prescription medications under a healthcare professional’s supervision
  • practicing good anal hygiene
  • using moistened wipes instead of toilet paper
  • bathing in warm salt water

People living with Crohn’s disease typically experience periods of flare-ups and periods of remission.

During periods of remission, symptoms may go away completely. During remission, people with Crohn’s may feel quite healthy. In other people, Crohn’s symptoms may still be present but reduced in frequency, intensity, or both.

Medical treatment can induce and maintain remission. It is also important that people adhere to prescribed treatments to stay in remission.
