there are a few different types of ulcerative colitis, which are categorised based on the location of inflammation in the colon: -Ulcerative proctitis: This type of ulcerative colitis affects only the rectum, which is the lowest part of the colon. It tends to be the mildest form and is characterized by rectal bleeding. - Left-sided colitis: In this type, inflammation extends beyond the rectum and affects the sigmoid colon (part of the lower left side) and descending colon (the left side of the colon). Symptoms can include bloody diarrhoea and unintended weight loss. - Pancolitis: Also known as extensive colitis, this type affects the entire colon. Symptoms can be severe and may include severe bloody diarrhea, intense abdominal pain, and fatigue. Acute severe ulcerative colitis: This is a rare and severe form of ulcerative colitis that affects the entire colon. It can cause intense pain and make it difficult to eat. Hospitalization is often required, and there is an increased risk of surgery. These different types of ulcerative colitis have varying levels of severity and can affect different parts of the colon. It's important to work with a healthcare professional to properly diagnose and manage the specific type of ulcerative colitis you have.
