An intestinal obstruction is a blockage in the small or large intestine, stopping food, fluids, gas, and stool from passing through, requiring prompt medical care as it can lead to serious complications like tissue death, infection, or rupture. Symptoms include severe abdominal pain, cramping, bloating, nausea, vomiting, and inability to pass gas or stool, often caused by adhesions from surgery, hernias, tumors, or inflammatory diseases like Crohn's. Treatment often involves fluids, decompression, and sometimes surgery, depending on the cause
