Can diet help me manage Crohn’s disease symptoms?

Question

Hello doctor,

I am 33 years old and was recently informed that I may have Crohn’s disease after an MRI showed small-bowel thickening. My symptoms include diarrhea, weight loss, and occasional blood in my stool. I also have a cousin with Crohn’s disease, so I am wondering whether family history could be a factor. I would appreciate clarification on how Crohn’s disease differs from ulcerative colitis.

I am also concerned about what this diagnosis may mean long-term; whether it typically requires lifelong medication or if surgery may be needed in the future. I am feeling quite weak and worried about malnutrition. Additionally, I would like to understand whether dietary changes can help reduce flare-ups or if medication is the primary treatment option.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I understand your concern.

Both Crohn's disease and ulcerative colitis are types of inflammatory bowel disease (IBD), but they show up in different ways and affect different parts of the body in different ways. Anyone with Crohn's disease can get it in any part of the digestive system, from the mouth to the anus. It often shows up in a "skip" or patchy way and can affect the lower parts of the bowel wall, which can cause problems like strictures, fistulas, or abscesses. Ulcerative colitis, on the other hand, only affects the colon. It starts in the rectum and keeps spreading to the rest of the body.

A person's risk does go up if they have a family history of IBD. Most patients need long-term care, but many can live a good life for long periods of remission. When someone has Crohn's disease and has problems like strictures, abscesses, or fistulas, they may need surgery. However, if they get good medical care, they can often put off or avoid surgery for many years.

The next steps are to confirm the diagnosis and find out how bad the sickness is. Usually, this includes tests on the stool (like those to rule out illness), blood tests like a full blood count and inflammatory markers, fecal calprotectin, a colonoscopy with biopsies of the ileum, and sometimes a CT(computed tomography) or MR(Magnetic resonance) enterography.

Making changes to your diet can help you deal with your symptoms and get enough nutrients, but they rarely get rid of gut inflammation on their own. During disease flare-ups, strategies may include eating small, high-protein meals more often; following a low-fat or low-residue diet if there are restrictions; staying away from foods that make you sick (often lactose, greasy, or spicy foods); taking nutritional supplements by mouth; and making up for deficiencies like iron, vitamin B12, and vitamin D. Medications, like short-term steroids followed by immunomodulators or biologic therapies, are the main way to heal the gut and keep problems from happening in the future.

For a more detailed discussion on any of these topics or to explore additional concerns, please feel free to schedule a consultation.

I hope this helps.

Thank you.
