Pyloric obstruction is a relatively common digestive disorder because the pylorus is the narrowest part of the digestive tract with a relatively small diameter and is therefore prone to obstruction. The symptoms that patients exhibit after the occurrence of pyloric obstruction are also relatively numerous. For example, abdominal distension, gas, hiccups and acid reflux, vomiting, weight loss, dehydration, urination, constipation, weakness, and many other symptoms. The most common symptom of pyloric obstruction is that there will be vomiting of overnight food, and the vomiting usually occurs some time after eating food. Because the food in the stomach does not enter the intestine after pyloric obstruction, it all gathers in the stomach, so all that is vomited out is the food that was eaten before. The patient’s stomach gradually enlarges and even forms a mass in the abdomen. Because food cannot enter the intestinal tract for nutrient absorption after pyloric obstruction, patients also experience dehydration, weight loss, weight loss, headache and dizziness, general weakness, and other symptoms. It is important to develop good eating habits, do not overeat, eat more food that is easy to digest and absorb, eat less cold and irritating food, do not drink and smoke, and have regular stomach health checks.
