Abdominal pain

life science Maturity 11-13 Next article →

Abdominal pain is a common symptom that can mean many different things. People often call it a stomach ache. Because the abdomen holds most of your vital organs, pain there can signal many different health issues. Some causes are not serious at all. However, about 15% of cases involve a more serious condition. These might include appendicitis or a ruptured abdominal aortic aneurysm.

Pain can start in several different ways. Sudden onset pain happens in a split second. Rapid onset pain starts mild and grows worse over a few minutes. Gradual onset pain takes hours or even days to intensify. People also describe the feeling of the pain differently. Cramping pain comes in waves that build and then stop. Other pain feels dull or aching. This often happens when a hollow organ is stretched or swollen.

Doctors use specific tools to find the cause of the pain. They often divide the abdomen into four areas called quadrants. The location of the pain provides important clues. For example, pain in the right upper quadrant might involve the liver or gallbladder. Pain near the belly button can be a sign of appendicitis. In some cases, the pain is "referred." This means the brain feels pain in one spot, but the problem is actually in a different organ.

There are many different reasons why the abdomen might hurt. Gastroenteritis is a very common cause, affecting 13% of people. Irritable bowel syndrome affects about 8% of people. Urinary tract problems and stomach inflammation both cause 5% of cases. Constipation is also a common cause at 5%. Some serious issues like cancer or diverticulitis are less common. In fact, doctors cannot find the exact cause in about 30% of all cases.

To understand the pain, doctors look at the body's internal systems. The gut is divided into the foregut, midgut, and hindgut. The foregut includes the stomach, liver, and pancreas. The midgut contains the appendix and parts of the colon. The hindgut includes the rectum and the end of the colon. Each part has its own nerves to send signals to the spinal cord. These nerves help the body tell the brain when something is wrong.
