Gastrectasis refers to the medical condition characterized by the abnormal dilation or enlargement of the stomach. It is derived from the combination of two Greek words: "gastros," meaning stomach, and "ektasis," meaning dilation or expansion.
In gastrectasis, the muscles and walls of the stomach lose their ability to contract and relax properly, resulting in the accumulation of food, gas, or fluid within the organ. This can cause the stomach to become distended, leading to discomfort, pain, and an impaired digestive function.
Gastrectasis can be caused by various factors, including structural abnormalities, such as obstructions or strictures within the stomach or nearby organs, as well as neurological disorders that affect the nerves controlling stomach movement. It can also be a consequence of certain medical conditions, such as gastroparesis (delayed stomach emptying) or gastric outlet obstruction.
Symptoms of gastrectasis may include persistent bloating, a feeling of fullness, nausea, vomiting, stomach pain, and indigestion. Diagnosing gastrectasis typically involves a thorough medical history, physical examination, and diagnostic tests like endoscopy, imaging studies (such as X-rays or CT scans), or gastric emptying studies.
Treatment for gastrectasis focuses on addressing the underlying cause and managing symptoms. This may involve lifestyle modifications, such as dietary changes, eating smaller and more frequent meals, and avoiding certain foods that aggravate the condition. Medications that enhance stomach motility or reduce stomach acid production may also be prescribed. In some cases, surgical intervention may be necessary to remove obstructions or repair structural abnormalities.
