Will biologics help to manage ulcerative colitis?

Question

Hello doctor,

I am a 29 year old female who was recently diagnosed with ulcerative colitis after months of bloody stools, urgency and abdominal cramps. I have been taking Mesalamine for 6 weeks but the flare ups come and go. I have a stressful job too and I can see my symptoms getting worse especially in busy weeks.

My gastroenterologist told me I could begin biologic therapy but I am concerned about the risk of infection and immune suppression long-term. Can you explain the difference between biologics and steroids and when do doctors decide they are needed?

Please help.

Thank you

Hello,

Welcome to icliniq.com.

I understand your concern

You have ulcerative colitis, an autoimmune inflammation of the large bowel. It causes abdominal pain, urgency and bloody stools. Stress can worsen symptoms, but it does not cause the disease.

Mesalamine works for mild to moderate disease. If, after six weeks, you still have repeated flares, it may mean the inflammation is not fully controlled. Persistent inflammation can damage the colon over time, so good control is important.

Steroids and biologics are different. Steroids (such as Prednisolone) are anti-inflammatory drugs that work rapidly to control inflammation and are used for short-term control of flares. But they are not safe for long-term use because of side effects like weight gain, bone loss, diabetes and mood changes.

Biologics are immune-directed medicines. Instead of suppressing the whole immune system, they are targeting specific inflammatory pathways. For instance, infliximab blocks an important inflammatory protein, tumor necrosis factor (TNF). Others, such as Vedolizumab, are gut-specific and may have a lower risk of systemic infection.

Biologics are considered when:

Mesalamine is not enough.
Frequent steroid use.
Moderate to severe disease.
High inflammatory markers on a colonoscopy showing active disease.

Infection risk exists but is monitored carefully. Before starting, doctors screen for TB (tuberculosis), hepatitis, and other infections. Many patients use biologics safely for years with proper follow-up.

The goal is not just symptom relief, but mucosal healing, meaning the colon lining heals on colonoscopy. That minimizes future problems and cancer risk. The decision will depend on the severity of your disease, blood tests, stool calprotectin, and colonoscopy findings.Good sleep, stress management, and a balanced diet help, but cannot replace medical treatment.

Biologics are not a failure; they are often a proactive step to prevent long-term damage.

If you share whether your disease is mild, moderate, or severe on colonoscopy, I can guide more specifically.

I hope this helps.

Kindly follow up if you have more concerns.
