Abdominal disorders refer to a range of medical conditions that affect the organs located in the abdomen, including the stomach, intestines, liver, and gallbladder. Common symptoms include pain, bloating, and changes in bowel habits. These disorders can be caused by infections, inflammation, or structural issues. Some common abdominal disorders include gastroenteritis, which is an inflammation of the stomach and intestines, and irritable bowel syndrome (IBS), a functional disorder affecting bowel function. Diagnosis often involves physical examinations, imaging tests, and laboratory tests to determine the underlying cause and appropriate treatment.
