Drinking water and feeling blocked can be caused by physiological factors such as diet, and may also be related to chronic gastritis, dyspepsia, pyloric obstruction and other pathologic factors. 1. Physiological factors: when patients overeat or eat too much fried food that is not easy to digest, stomach contents increase, and the feeling of stomach blockage may occur after drinking water. If the patient drinks cool water, it will stimulate the gastric mucosa, and the feeling of stomach blockage may also occur. 2. Malignant tumor of lower esophagus: Due to the presence of tumor, patients with malignant tumor of lower esophagus will affect the entry of food into the stomach, which will lead to the symptom of stomach blockage after drinking water. 3. Chronic gastritis: gastric mucosa in the long-term stimulation of inflammation, there will be gastric distension and stomach pain, acid belching and other symptoms, and in severe cases, there will be a feeling of gastric blockage after drinking water. 4. Dyspepsia: dyspepsia usually has a decrease in the secretion of digestive juices or digestive enzymes, and the digestive juices are diluted after drinking water, which affects the digestion and absorption of food, and prolongs the residence time of food in the stomach, which may also cause gastric blockage symptoms. 5. Pyloric obstruction: Blockage at the pylorus affects the passage of food from the stomach to the small intestine, and the food accumulates in the stomach. Drinking water at this time leads to a further increase in gastric contents, which makes the patient feel the stomach blockage. If patients have long-term or recurrent symptoms of stomach blockage when drinking water, it is recommended to consult a doctor in a timely manner, under the guidance of a professional physician to identify the cause of the disease, and to carry out targeted treatment.
