Gastroparesis
Gastroparesis is a condition that affects the stomach's ability to empty its contents properly. This delayed gastric emptying can lead to a range of uncomfortable symptoms. Common signs include nausea, vomiting, bloating, abdominal pain, and a feeling of fullness after eating only a small amount of food. Some people may also experience fluctuations in blood sugar levels due to the unpredictable digestion process.
Diagnosis of gastroparesis typically involves a combination of medical history review, physical examinations, and specific tests. One common test is the gastric emptying study, where a patient consumes a meal containing a small amount of radioactive material to track how quickly food moves through the stomach. Other diagnostic methods might include an upper endoscopy or imaging tests.
The causes of gastroparesis can vary. It is often linked to diabetes, particularly when high blood sugar levels damage the nerves that control stomach muscles. Other potential causes include certain medications, surgeries involving the stomach, and conditions such as Parkinson's disease or multiple sclerosis.
Treatment for gastroparesis aims to manage symptoms and improve gastric emptying. This can include dietary changes, such as eating smaller, more frequent meals and avoiding high-fat and high-fibre foods that can slow digestion. In some cases, medications that stimulate stomach contractions or help manage nausea may be prescribed. Severe instances might require more advanced treatments, such as gastric electrical stimulation or, in rare cases, surgery.
