Poor pyloric closure is a form of impaired pyloric function. Poor pyloric closure is mostly caused by decreased gastric peristalsis, in which stomach contents cannot be emptied in time, or by impaired pyloric function due to surgery on the pylorus. When patients have poor pyloric closure, they are prone to reflux gastritis and reflux esophagitis, with symptoms of abdominal distension and discomfort, acid reflux, belching (hiccups), and burning pain in the stomach area after meals. Poor pyloric closure is mainly treated with proton pump inhibitors and gastric stimulants, as well as mucosal protective drugs. Pay attention to light diet, avoid eating greasy food and stimulating food, chew slowly, do not overeat. If the patient has poor pyloric closure, it is recommended to seek medical treatment in time and carry out relevant treatment under the guidance of the doctor.
