There are several reasons why Crohn’s disease may cause you to vomit, including:

  • Bowel obstruction: Crohn’s can cause inflammation and a narrowing of the small intestine, which can lead to a bowel obstruction. This can block the movement of food and result in vomiting.
  • Nausea: Crohn’s disease can often cause symptoms such as bloating and abdominal pain after eating, which can trigger nausea. This may lead to vomiting.
  • Medication side effects: Some medications used to treat Crohn’s disease may cause vomiting as a side effect. This commonly includes drugs like azathioprine (Imuran) and metronidazole (Flagyl).

Here are some tips that can help you manage vomiting when you have Crohn’s disease:

  • Avoid trigger foods: Certain foods may trigger symptoms, particularly when you are having a flare-up. Consider limiting or avoiding food and drink containing dairy, caffeine, and gluten.
  • Eat frequent, small meals: If you feel nauseous, it can often be helpful to eat small meals and snacks throughout the day. This can make it easier for your stomach to digest food.
  • Try natural remedies: Many natural treatment options, such as ginger, may help alleviate nausea and vomiting. Try adding fresh ginger to tea or incorporating it into your meals.
  • Consider anti-nausea medications: If you regularly experience nausea and vomiting, it may be beneficial to speak with a doctor about anti-nausea medications, also known as antiemetics. They can help to reduce or prevent nausea and vomiting.

If you have been vomiting for more than 24 hours or have blood in your vomit, you should speak with a healthcare professional immediately.
