Drinking milk in the middle of the night when a patient has stomach pain is not expected to have a relieving effect, and may have the opposite effect. If the cause of stomach pain is due to excessive secretion of stomach acid, drinking milk at this time may aggravate the secretion of stomach acid and cause more stomach pain, it is recommended that patients can drink warm water instead. If the symptoms of stomach pain in the middle of the night occur frequently and repeatedly, it is mostly considered to be the presence of duodenal ulcer, and it is recommended that patients can prepare their own acid-suppressing drugs for treatment, such as oral omeprazole or lansoprazole, ranitidine, etc. Patients are also advised to visit the hospital in a timely manner and cooperate with the doctor to give an examination of electronic gastroscopy to assist in a clear diagnosis. If the presence of gastric diseases is confirmed, especially if peptic ulcers are present, regular cooperation with a specialist is needed to give medication treatment.
