Gastric outlet obstruction refers to a condition in which there is a blockage or narrowing at the point where the stomach connects to the small intestine, known as the pylorus. This blockage can occur due to various reasons such as tumors, scar tissue formation, inflammation, or the presence of foreign objects.
Common symptoms of gastric outlet obstruction include persistent nausea and vomiting, particularly after meals, as food and gastric juices cannot pass through the narrowed or blocked area. This can lead to a feeling of fullness or bloating, loss of appetite, and weight loss. In some cases, individuals may experience abdominal pain or discomfort.
Diagnosis of gastric outlet obstruction typically involves a thorough medical history review, physical examination, and various imaging tests such as abdominal ultrasound, computed tomography (CT) scan, or an upper gastrointestinal series. These tests help to identify the location and cause of the blockage.
Treatment options for gastric outlet obstruction depend on the underlying cause and severity of the condition. In some cases, medications may be prescribed to reduce inflammation or to alleviate symptoms of nausea and vomiting. However, if the obstruction is severe or does not respond to conservative treatment, surgical intervention may be necessary to remove the blockage or to bypass the narrowed area and restore proper digestive function.
Overall, gastric outlet obstruction is a condition characterized by the narrowing or blockage of the pathway between the stomach and the small intestine, leading to symptoms such as nausea, vomiting, and abdominal discomfort. Prompt medical attention and appropriate treatment are essential to relieve symptoms and prevent complications.
