Indigestion, also known as dyspepsia or an upset stomach, is a condition that describes discomfort in the upper abdomen with symptoms of abdominal pain and a feeling of fullness after eating. It is often a sign of an underlying problem, such as gastroesophageal reflux disease (GERD), ulcers, or gallbladder disease, rather than a condition of its own. Some symptoms include bloating, belching and gas, nausea and vomiting, an acidic taste in the mouth, fullness during or after a meal, growling stomach, burning in the stomach or upper belly, and/or belly pain. To diagnose, the doctor will likely start by asking questions about medical history and eating habits. A patient will undergo a physical examination. The doctor may order X-rays of the abdomen to see if there are any abnormalities in the digestive tract. They may also collect blood, breath, and stool samples to check for a type of bacteria that causes peptic ulcers. Also, the doctor can order an endoscopic exam to check the upper digestive tract for abnormalities.
