Overview

Ulcerative colitis is a long-term inflammatory bowel disease that mostly affects the inner lining of the colon and rectum. The condition causes constant inflammation and the formation of small ulcers on the intestinal surface. This leads to digestive problems and poor nutrient absorption. Ulcerative colitis usually comes and goes, with periods of flare-ups and periods of no symptoms. It can happen at any age, but young adults are more likely to be diagnosed with it. The severity ranges from mild inflammation to a disease affecting the entire colon. To avoid problems, it is important to get an early diagnosis and long-term care.

Symptoms
Common signs include frequent diarrhea, which may contain blood or mucus, stomach pain, and a strong urge to defecate. People may feel tired, lose weight, and have a reduced appetite. When flare-ups happen, you may get a fever and become dehydrated. Some people also get joint pain, skin problems, or eye inflammation. Poor nutrient absorption can slow a kid's growth.

Causes
The precise aetiology of ulcerative colitis remains unidentified. It is thought to be caused by an abnormal immune response that attacks the lining of the intestines. Genetic predisposition, environmental factors, and alterations in gut microbiota may play a role. Stress and diet do not directly cause the disease, but they can make symptoms worse when they flare up.

Diagnosis
To find out whether someone has inflammation or anaemia, doctors review their medical history, perform a physical exam, and order lab tests. Stool tests help rule out infections. A colonoscopy with biopsy is the most important test to confirm that the colon remains inflamed. Imaging studies may be used to evaluate the extent of disease and associated complications.

Treatment
The goal of treatment is to reduce inflammation, ease symptoms, and prevent the disease from returning. Some medicines that may be used are anti-inflammatory drugs, immune-modulating therapies, and biologic agents. Dietary changes and nutritional support can help with symptoms. In serious cases or when complications happen, it may be necessary to surgically remove the affected colon. It is very important to keep an eye on things.

Ulcerative colitis is a chronic condition characterized by cycles of remission and exacerbation. Many people live productive lives after getting the right treatment and follow-up. Early management reduces the risk of problems and improves overall life.
