Stomach cancer is a disease that causes great discomfort in the stomach, such as upper abdominal discomfort, bloating and hiccups. After having stomach cancer surgery, there will be some patients who still have hiccups. If hiccups occur, it depends on whether they are frequent or not. If they are occasional, they may be caused by stomach discomfort and do not need special treatment. If the hiccups are frequent, it is necessary to rule out the possibility of recurrence of stomach cancer. According to the time when the patient had the surgery, if the patient has been operated for more than half a year, he/she should consult the doctor at the first time to receive the follow-up consultation and arrange the gastroscopy examination. If the recurrence of cancer is ruled out, you can let the doctor prescribe medicines to relieve stomach acid and protect the gastric mucosa, or medicines to treat indigestion according to the condition.
