Ulcerative Colitis (রক্ত আমাশয়) in Dhaka — Symptoms, Diet & Treatment

Ulcerative Colitis in Bangladesh — Symptoms, Causes, Diet & Treatment / আলসারেটিভ কোলাইটিস

Ulcerative colitis (UC) — আলসারেটিভ কোলাইটিস — is a chronic autoimmune disease of the large intestine (colon and rectum) that causes ulcers, bleeding and persistent diarrhoea.

In Bangladesh, most patients with ulcerative colitis are initially misdiagnosed as রক্ত আমাশয় (bloody dysentery) and treated with anti-amoebic drugs for months or years before the correct diagnosis is made.

Understanding the difference between ulcerative colitis and infectious dysentery is the most important step in getting effective treatment in Bangladesh.

Colitis Meaning in Bengali / কোলাইটিস মানে কী?

Colitis meaning: কোলাইটিস অর্থ হলো বৃহৎ অন্ত্রের (colon-এর) প্রদাহ।

Ulcerative colitis meaning: আলসারেটিভ কোলাইটিস হলো বৃহৎ অন্ত্রের দীর্ঘমেয়াদী প্রদাহজনিত রোগ যেখানে অন্ত্রের ভেতরের আবরণে ঘা (আলসার) তৈরি হয়, রক্ত ও মিউকাসযুক্ত পায়খানা হয়। এটি একটি অটোইমিউন রোগ — অর্থাৎ শরীরের নিজের প্রতিরক্ষাব্যবস্থা নিজের অন্ত্রের টিস্যুকে আক্রমণ করে।

✅ Quick Summary / সংক্ষেপে

Is Bloody Diarrhoea Always Infection? / রক্ত আমাশয় কি সব সময় সংক্রমণ?

The most important question for any Bangladeshi patient with bloody diarrhoea: is this infectious or inflammatory?

The answer determines everything about treatment — yet in Bangladesh, this distinction is frequently missed, leading to an average diagnostic delay of 2–5 years for ulcerative colitis.

Ulcerative Colitis (আলসারেটিভ কোলাইটিস)

Cause: Autoimmune — immune system attacks own colon lining. NOT infectious.

Onset: Gradual — weeks to months of worsening symptoms

Duration: Chronic — months to years; flares and remissions

Treatment: Mesalazine, steroids, immunosuppressants, biologics — NOT antibiotics

Amoebic Dysentery (অ্যামিবিক আমাশয়)

Cause: Entamoeba histolytica parasite (infection)

Onset: Can be acute or gradual

Duration: Resolves with treatment

Treatment: Metronidazole + diloxanide furoate

Bacillary Dysentery (ব্যাকটেরিয়াল আমাশয়)

Cause: Shigella bacteria (infection)

Onset: Acute — sudden onset within days

Duration: Self-limiting 5–7 days if mild

Treatment: ORS; ciprofloxacin for severe cases

⚠️ Critical for Bangladesh Patients

If you have been treated multiple times for রক্ত আমাশয় but symptoms keep returning — especially with mucus in stool, left-sided abdominal cramping and urgency — you need a colonoscopy and biopsy. This is the only way to diagnose ulcerative colitis definitively.

Types of Ulcerative Colitis / কোলাইটিসের ধরন

UC is classified by how much of the colon is affected — this determines symptoms, treatment intensity and cancer surveillance frequency:

Ulcerative Proctitis (Rectum Only)

Affects only the rectum (last 15–20cm). Symptoms: rectal bleeding, urgency. Often mistaken for piles. Generally mildest form. Treatment: rectal suppositories or enemas of mesalazine.

Left-Sided UC

Affects rectum to descending colon. Symptoms: bloody diarrhoea, left abdominal pain, weight loss during flares. Treatment: oral + rectal mesalazine; steroids for flares.

Pancolitis (Extensive UC) — Most Severe

Entire colon affected. Symptoms: frequent bloody diarrhoea, significant weight loss, fatigue, anaemia, fever. Highest cancer risk. Treatment: oral mesalazine; early immunosuppression; biologics. Most likely to need surgery.

Causes & Cancer Risk / কারণ ও ক্যান্সারের ঝুঁকি

What Causes UC? / কারণ

UC is not caused by any infection, food, or lifestyle factor — it is an autoimmune disease caused by:

Cancer Risk / ক্যান্সারের ঝুঁকি

UC does carry an increased risk of colorectal cancer — but this risk is manageable with regular colonoscopy surveillance:

Diagnosis / রোগ নির্ণয়

Accurate diagnosis of UC requires colonoscopy with biopsy — there is no blood test or stool test alone that can confirm UC.

Colonoscopy with Biopsy ⭐ (The Definitive Test)

Shows continuous mucosal inflammation starting at the rectum, extending proximally. Biopsies show crypt distortion, cryptitis, goblet cell depletion — diagnostic of UC.

Stool Microscopy and Culture

Essential first step to exclude amoebic and bacterial dysentery. Must be done before treating as UC.

Blood Tests

Complete blood count (anaemia), CRP/ESR (inflammatory markers), stool calprotectin (bowel inflammation marker).

Treatment / চিকিৎসা — Step-by-Step

UC treatment follows a stepwise approach. The goal: (1) induce remission during flares, (2) maintain remission long-term, (3) prevent complications and cancer.

Step 1 — Mesalazine (5-ASA) / মেসালাজিন

First-line for mild to moderate UC. Works directly on the colon lining to reduce inflammation. Available in Bangladesh (Mesacol, Pentasa, Asacol). Delivered orally (tablets) AND/OR rectally (suppositories/enemas). Maintenance therapy required indefinitely — stopping leads to relapse.

Step 2 — Corticosteroids / স্টেরয়েড

For moderate to severe flares. Prednisolone (oral) or IV hydrocortisone (hospital) controls acute flares rapidly. NOT maintenance therapy — should not be used long-term due to side effects.

Step 3 — Immunosuppressants / ইমিউনোসাপ্রেসেন্ট

For steroid-dependent UC. Azathioprine or mercaptopurine — taken orally daily. Take 3–6 months to reach full effect. Require regular blood tests. Available in Bangladesh.

Step 4 — Biologics / বায়োলজিক্স

For moderate-severe refractory UC. Infliximab is the most widely used biologic for UC in Bangladesh — given as IV infusions every 6–8 weeks. Highly effective. Expensive but available at major Dhaka hospitals.

Step 5 — Surgery / অস্ত্রোপচার

When needed: Severe UC not responding to medical therapy; fulminant UC or toxic megacolon (emergency); chronic steroid-dependent UC; dysplasia or cancer found on surveillance.

J-pouch surgery: Entire colon and rectum removed; small intestine fashioned into J-shaped pouch connected to anus. Allows normal defecation without permanent stoma. Functional cure — no more UC possible.

Diet Plan / খাদ্যতালিকা — Bangladesh Food Guide

Key principle: during a flare, eat low-residue, easy-to-digest foods; during remission, gradually expand the diet.

Common Questions / সচরাচর জিজ্ঞাসা

What is ulcerative colitis? / আলসারেটিভ কোলাইটিস কি?

Ulcerative colitis is a chronic autoimmune inflammatory disease of the colon and rectum — NOT an infection. It causes bloody diarrhoea, abdominal pain and urgency in recurring flares over a lifetime. আমাশয়ের ওষুধ (মেট্রোনিডাজল) এই রোগ সারায় না।

Is ulcerative colitis curable? / আলসারেটিভ কোলাইটিস কি সারে?

Medicine cannot cure UC — but it achieves long remission in most patients. Surgery (colectomy) is a permanent cure as it removes the diseased colon. With correct treatment, most patients live a completely normal life.

What’s the difference between রক্ত আমাশয় and ulcerative colitis?

রক্ত আমাশয় is a symptom (bloody diarrhoea) — it can be caused by infectious dysentery (bacteria/parasite) OR by ulcerative colitis (autoimmune). If bloody diarrhoea keeps recurring despite antibiotic treatment, ulcerative colitis must be excluded by colonoscopy.

Does ulcerative colitis cause cancer? / ক্যান্সারে পরিণত হয়?

UC itself is not cancer — but long-standing poorly controlled UC increases colorectal cancer risk (3–5×). With regular surveillance colonoscopy every 1–3 years and good disease control, most UC patients never develop cancer.

Can UC be treated in Bangladesh? / বাংলাদেশে চিকিৎসা কি হয়?

Yes — UC can be fully managed in Bangladesh. Mesalazine, steroids, azathioprine and infliximab (biologic) are available. Colonoscopy and biopsy available in Dhaka. Dr. Nazrul Islam provides complete UC management including surgery. Call: +880 1976-842234.
