Intestinal obstruction occurs when there is a blockage in the intestines, preventing food, fluids, and gas from passing through. This can happen due to various reasons, including hernias, tumors, or scar tissue from previous surgeries. Symptoms often include abdominal pain, bloating, vomiting, and constipation. If left untreated, intestinal obstruction can lead to serious complications, such as intestinal perforation or infection. Diagnosis typically involves imaging tests like X-rays or CT scans, and treatment may require hospitalization, where options include nasogastric tubes to relieve pressure or surgery to remove the blockage.
