Biliary reflux gastritis is caused by the slow peristalsis of the gastrointestinal tract itself and the reflux of bile secreted by the duodenum into the stomach cavity due to poor digestion in the gastrointestinal tract. Most bile reflux will manifest as upper abdominal discomfort, burning sensation or pain behind the sternum. It is generally recommended to elevate the upper body 15-30 degrees as much as possible during sleep, and to sleep in a left-sided position. As far as possible, do not sleep immediately after eating within half an hour, and pay attention to rest after meals as appropriate, so that you can move appropriately, and also do not eat spicy, fried or greasy food as far as possible, which is also a way to reduce reflux symptoms. There are no absolute requirements for other positions of sleep. To improve gastrointestinal function or reduce reflux and other medications, if repeatedly do not see relief, you need to improve gastroscopy to further assist in diagnosis and treatment.
