Best Gastroenterologists for Colonoscopy in Chennai, India

Ulcerative colitis is a long-term condition in which the immune system triggers ongoing inflammation in the lining of the colon and rectum, leading to ulcers, bleeding, and disruption of normal bowel function. It follows a relapsing-remitting course in most people, meaning periods of active symptoms alternate with periods of remission.

Common symptoms include frequent or urgent diarrhoea—often containing blood or mucus—persistent abdominal cramping, rectal pain or urgency, unintended weight loss, and fatigue. Some patients also experience symptoms outside the gut, such as joint pain, mouth ulcers, or skin changes. It is important to note that these symptoms overlap with other bowel conditions, and their presence alone is not sufficient to confirm a diagnosis of ulcerative colitis.

Diagnosis typically involves a combination of clinical assessment, blood tests (looking for anaemia, elevated inflammatory markers such as CRP and ESR, and nutritional deficiencies), and stool tests including faecal calprotectin. Endoscopic examination—most commonly a colonoscopy, sometimes with targeted biopsies—is the definitive step, allowing a gastroenterologist to visualise the extent and pattern of inflammation and confirm the diagnosis histologically. Disease severity and extent are usually classified using validated indices such as the Mayo Score or Montreal Classification, which guide treatment decisions.

Treatment is highly individualised and depends on the extent of disease (proctitis, left-sided, or extensive/pancolitis), current severity (mild, moderate, or severe), and the patient's overall health and treatment history. Mild-to-moderate disease is usually managed with medication, whereas severe or steroid-refractory disease may require escalation to biologic or immunomodulator therapy, and a small proportion of patients may ultimately need surgical intervention such as colectomy. Regular monitoring through clinical review and repeat colonoscopy is a standard part of long-term care.

The majority of people with ulcerative colitis are managed without surgery, using a stepped approach that may include aminosalicylates (such as mesalazine) for mild disease, corticosteroids to control acute flares, and longer-term immunomodulators (such as azathioprine) or biologic agents (such as anti-TNF therapies or integrin inhibitors) for moderate-to-severe or frequently relapsing disease. Dietary guidance and nutritional support play a supportive role, and smoking cessation is particularly relevant as smoking can influence disease behaviour in UC. The specific medications, doses, and monitoring schedules appropriate for any individual must be determined by a qualified clinician based on a full assessment.

Colonoscopy may be considered only when it is appropriate for the confirmed diagnosis and the expected benefit outweighs the individual risks. The decision may depend on symptom severity, investigation results, previous treatment, overall health and the patient's goals. A specialist should discuss alternatives and recovery before any procedure is planned.

Ulcerative colitis is primarily evaluated and managed by a gastroenterologist, ideally one with a subspecialty interest in inflammatory bowel disease (IBD). Patients with complex or refractory disease, or those being considered for surgery, are best served by a multidisciplinary team that may also include a colorectal surgeon and, where extraintestinal manifestations are present, relevant specialists such as a rheumatologist or hepatologist.

When comparing providers, look for a gastroenterologist with demonstrable experience in managing inflammatory bowel disease, access to the full spectrum of biologic therapies, and affiliation with a centre that offers both endoscopic services and colorectal surgical backup should escalation be needed. Consistent follow-up and a structured surveillance colonoscopy programme are important indicators of comprehensive long-term care.

Share a concise medical summary, symptom timeline, previous diagnoses, investigation and imaging reports, procedure or biopsy reports where relevant, current medicines, allergies and related treatment records. Provide clear copies with translations when needed. The reviewing doctor may request additional information before giving an opinion.
