Colorectal Disorders

Colorectal disorders are a wide range of diseases that affect the colon and rectum. They can change how the intestine moves, how well the mucosa stays intact, how well blood flows, and the risk of cancer. Inflammation, infection, blood flow issues, or cancer can cause these problems. Ulcerative colitis and Crohn's disease are two common inflammatory diseases that fall under the umbrella of inflammatory bowel disease (IBD). Functional illnesses like Irritable Bowel Syndrome mainly change how the intestine works without causing any structural problems.

Neoplastic disorders include benign polyps and malignant tumours, such as colorectal cancer, which is one of the most common causes of cancer death globally. Other problems are diverticular disease, ischaemic colitis, anorectal conditions (such as haemorrhoids and fissures), and infectious colitis.
The clinical signs and symptoms can vary, but they often include abdominal pain, changes in bowel habits (constipation or diarrhoea), rectal bleeding, mucus discharge, bloating, tenesmus, and unintentional weight loss. Anaemia or bleeding that doesn't stop are signs that you need to see a doctor right away.

A diagnostic examination includes a colonoscopy, a sigmoidoscopy, stool tests, imaging (CT/MRI), and a histopathological biopsy. Management techniques vary depending on the cause and may involve changing the diet, using medications (such as anti-inflammatory drugs or biologics), performing endoscopic procedures, or undergoing surgery to remove the problem. Preventive screening and early intervention are essential for decreasing morbidity and enhancing long-term colorectal health outcomes.
