What supplements help control Crohn’s flares in my sister?

Question

Hello doctor,

My sister, aged 27, was recently diagnosed with Crohn’s disease after a colonoscopy showed terminal ileum ulcers, and a biopsy confirmed inflammation.

Her CRP is 24 mg/L, and she has been started on Azathioprine along with steroids.

So my concerns are:

How long does it usually take for symptoms such as abdominal pain and diarrhea to improve after starting treatment?
Are flare-ups common even while on maintenance medications?
She is losing weight steadily. Should we consider any specific nutritional supplements or a low-fiber diet?
Also, can Crohn’s disease affect fertility or pregnancy in the future?
The doctor mentioned biologics if her condition does not improve. Are biologics safe for long-term use, and do they cause immunity-related problems?

Kindly help.

Hello,

Welcome to icliniq.com

I have read your query and understand your concerns.

Steroids usually improve pain and diarrhea within a few days to two weeks if an infection or abscess is not present. They act quickly to control inflammation while other, slower medications take effect.

Azathioprine works more slowly, with initial benefits often starting in six to twelve weeks and the full effect taking three to four months. Therefore, steroids are commonly used as a bridge until azathioprine becomes effective.

Flares can still occur while on maintenance therapy due to missed doses, infections, nonsteroidal anti-inflammatory drugs, smoking, stress, or underdosing.

The main goal of maintenance treatment is to achieve long-term remission with normal C-reactive protein and fecal calprotectin levels.

Ongoing weight loss requires further evaluation, including checking for anemia, vitamin B12, iron, and vitamin D deficiencies. Nutritional support, such as high-calorie oral supplements, adequate protein, and small, frequent meals, should be considered.

During active ileal disease or strictures, a low-residue or low-fiber diet can help reduce pain and obstruction symptoms. Once the disease is controlled, the diet can be gradually broadened to include more fiber.

Exclusive enteral nutrition can also be helpful for some patients, especially when oral intake is insufficient or symptoms are severe. This approach provides complete nutrition while allowing the bowel to rest.

Fertility is generally normal when the disease is in remission, but active disease and poor nutrition can reduce fertility more than approved medications.

Pregnancy outcomes are best when the disease has been quiet for three to six months before conception, and azathioprine is often continued if necessary.

Biologic therapies are used if steroids cannot be tapered, symptoms persist, or inflammatory markers remain elevated.

They are generally safe for long-term use with monitoring, but the main risks include infections and rare signals for malignancy, which must be balanced against the harms of uncontrolled Crohn’s disease.

Thanks and regards.
