Colonic dilatation refers to the abnormal enlargement of the colon beyond its normal diameter. It can occur due to various factors such as obstruction, inflammation, or functional disorders. Symptoms may include abdominal distention, pain, nausea, and changes in bowel habits. Diagnosis typically involves imaging studies like X-rays or CT scans. Treatment depends on the underlying cause and may include addressing obstructions, medications, decompression, and supportive care. Without prompt management, colonic dilatation can lead to serious complications such as bowel perforation.
