Will biologics help to manage ulcerative colitis?

Question

Hello doctor,

I am a 29-year-old woman who was recently diagnosed with ulcerative colitis after months of bloody stools, urgency, and abdominal cramps. I have been taking Mesalamine for six weeks, but the flare-ups still come and go. I also have a stressful job, and I notice that my symptoms worsen, particularly in demanding weeks.

My gastroenterologist mentioned the possibility of starting biologic therapy, but I am concerned about the risk of infections and long-term immune suppression. Could you explain how biologics differ from steroids and how doctors decide when they are needed?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

You have ulcerative colitis, which is an autoimmune inflammation of the colon. It causes bloody stools, urgency, and abdominal cramps. 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 (like Prednisolone) reduce inflammation quickly and are used for short-term control of flares. They are not safe long-term because of side effects like weight gain, bone loss, diabetes, and mood changes.

Biologics are targeted immune medicines. They block specific inflammatory pathways instead of suppressing the whole immune system. For example, Infliximab blocks TNF (tumor necrosis factor), a key inflammatory protein. Others, like Vedolizumab, act mainly in the gut and may have lower systemic infection risk.

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. This reduces future complications and cancer risk. The decision depends on your disease severity, 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.

Thank you.
