Here's How Long Crohn's Flare-Ups Typically Last

A Crohn's flare-up can be extremely painful. So much so, that on days when symptoms are most severe, it can affect one's ability to function as they normally would. A flare-up occurs when symptoms of Crohn's disease return or intensify (via the Crohn's & Colitis Foundation). These symptoms may include diarrhea, abdominal pain, bloody stool, frequent or urgent bowel movements, lack of appetite, fatigue, and weight loss.

The length of a Crohn's flare-up can vary from person to person and at different points in time, as symptoms can last for a few days, weeks, or months (via Healthline). Talk to your doctor about any new or worsening symptoms so the two of you can work together on how to best manage the condition.

A number of factors may be at play to cause a Crohn's disease flare-up including changes in medication, an infection, chronic stress, smoking tobacco, and environmental pollution. Certain medications, such as antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs), can also prompt a flare-up. However, it's important to note that researchers are still working to better understand Crohn's disease and what causes flares. There's no way to predict exactly when flares will occur or how severe they will be.
