Could food and stress trigger ulcerative colitis flares?

Question

Hi doctor,

I am a 35-year-old female. I have ulcerative colitis that is mostly left-sided. My question is primarily about lifestyle. Whenever I eat outside food, especially spicy or fried dishes, I experience loose stools with a little mucus the next day. However, sometimes my symptoms flare up even after consuming simple home-cooked meals, so I am unsure about the triggers.

Currently, I am taking Mesalamine at a dosage of 2.4 grams per day, and I am not on steroids. Is diet truly the main trigger, or can inflammation occur independently? Should I consider adopting a gluten-free or dairy-free diet permanently?

Additionally, stress plays a significant role; when I have a conflict with someone or experience tension at work, I immediately feel stomach discomfort. There is a connection between my mind and gut, but I am not sure how much of this is true.

Please help.

Hi,

Welcome to icliniq.com.

I am deeply concerned about your worries.

Your experience is common among people with ulcerative colitis, especially when the disease affects the left side of the colon. It is important to understand that while diet does not cause ulcerative colitis, certain foods can irritate the bowel and temporarily worsen symptoms during times when the intestine is sensitive or mildly inflamed.

Foods that are spicy, fried, or from restaurants often trigger symptoms because they are high in fat, spices, and additives, which can stimulate the bowel and increase stool frequency.

However, flare-ups can also happen even after eating simple home-cooked meals, as the underlying inflammation in ulcerative colitis can fluctuate on its own. Thus, while diet can trigger symptoms, it is not the main cause of disease activity.

As for gluten and dairy, most patients with ulcerative colitis do not need to permanently avoid these foods unless they notice specific symptoms after consuming them. Some individuals may experience lactose intolerance, which can lead to bloating or loose stools. Rather than imposing strict, lifelong restrictions, it is better to identify personal trigger foods and moderate their intake.

Currently, you are taking Mesalamine, which is an effective maintenance treatment for controlling inflammation.

Your observation about stress is also valid; the connection between the gut and brain is well established. Emotional stress can heighten bowel sensitivity, alter gut movement, and exacerbate symptoms. While stress does not cause ulcerative colitis, it can intensify abdominal discomfort and bowel urgency.

Here are some helpful lifestyle measures you can consider:

Eat simple, balanced meals and avoid heavy, fried foods.
Keep a food and symptom diary.
Manage stress through exercise, meditation, or relaxation techniques.
Maintain regular follow-up appointments with your gastroenterologist.

With good adherence to medication and a balanced lifestyle, many patients can achieve long periods of remission and stable symptoms.

I hope this helps address your query.

Thank you.
