Causes of Ulcerative Colitis
Immune System Dysfunction: It's thought that ulcerative colitis might occur when the immune system mistakenly attacks the lining of the colon and rectum. This immune response can lead to inflammation and ulceration.
Genetic Factors: There is evidence that genetic predisposition plays a role in ulcerative colitis. People with a family history of inflammatory bowel disease have a higher risk of developing the condition, suggesting that certain genes may make individuals more susceptible.
Environmental Triggers: Various environmental factors might trigger ulcerative colitis in genetically predisposed individuals. These can include infections, certain medications, or dietary factors, although no specific environmental trigger has been definitively proven.
Microbiome Imbalance: The gut microbiome, which consists of trillions of microorganisms living in the intestines, may influence the development of ulcerative colitis. An imbalance in the microbiome could contribute to inflammation and immune system dysregulation.
Left-sided colitis is a type of ulcerative colitis that affects the left side of the colon, extending from the descending colon to the rectum. This form of colitis can cause symptoms such as abdominal pain, particularly on the left side, persistent diarrhea that may be bloody, and weight loss. The inflammation can lead to cramping, urgency, and discomfort, which can significantly impact daily activities and overall well-being. Effective management of left-sided colitis often involves medications to reduce inflammation and dietary adjustments to alleviate symptoms.
Pancolitis is the most extensive form of ulcerative colitis, involving inflammation of the entire colon. This widespread inflammation can result in severe symptoms, including frequent and urgent diarrhea, significant abdominal pain, and substantial weight loss. Patients with pancolitis may also experience fatigue, anemia, and a higher risk of complications such as colon dilation or toxic megacolon. Due to the extensive nature of the disease, treatment often involves a combination of medications to control inflammation and manage symptoms, along with close monitoring to prevent and address potential complications.

Ulcerative colitis is a chronic inflammatory bowel disease that causes inflammation and ulcers in the lining of the colon and rectum. It is characterized by symptoms like abdominal pain, diarrhea, and rectal bleeding.
Common symptoms include frequent and urgent bowel movements, abdominal cramps, rectal bleeding or mucus, diarrhea (often with blood or pus), weight loss, fatigue, and sometimes joint pain or skin problems.
The exact cause of ulcerative colitis is not known. It is believed to result from a combination of genetic, environmental, and immune system factors. It is not caused by infections or stress, although stress can worsen symptoms.
Diagnosis is typically based on a combination of medical history, physical examination, laboratory tests, endoscopy, and biopsy. A colonoscopy is commonly used to visualize the colon and obtain tissue samples.
Treatment aims to reduce inflammation, manage symptoms, and achieve and maintain remission. Options include medications (such as anti-inflammatory drugs, immunosuppressants, and biologics), dietary changes, and sometimes surgery.
There is no cure for ulcerative colitis, but it can be managed effectively with treatment. In some cases, surgery to remove the colon (colectomy) can provide relief from symptoms and is considered a cure.
