Sexual life is possible after 2/3 of stomach cancer has been removed and recovered. Gastric cancer is a cancer originated from gastric mucous membrane epithelium, which is caused by many factors. Early stage of the disease is asymptomatic, and some patients may have symptoms such as fullness, bloating, discomfort and dyspepsia. Surgery is an effective way to get a radical cure. Surgical resection of gastric cancer has less effect on sex life, and it is possible to have sex life when 2/3 of the resection has been recovered, but it is necessary to avoid excessive sex life. After gastric cancer resection, patients should pay attention to regular rechecking, monitor their own changes on daily basis, whether there is black stool and other conditions, and consult doctor in time if there is any abnormality. Meanwhile, patients should pay attention to light diet, eat more high protein food and avoid spicy and stimulating food.
