Whether the patient can have intercourse after stitches or not is subject to objective analysis based on the healing of the patient’s stitches incision. If the patient has undergone open surgery for gastric malignant tumor and has an incision of 25㎝ in the abdomen, and the stitches are less than one week, the patient’s nutritional status is poor at this time, and the physical strength has not fully recovered and the incision has not completely healed. Intercourse will not only consume a lot of energy, but also affect the healing of the incision, and may even cause the incision to be split and need a second operation, so intercourse is not possible at this time. Second, if the patient is given two stitches after sterilization treatment for hand iron cut, the local incision is healing well, there is no obvious incision infection performance, the patient short time intercourse will not have too much impact on the human body, but it is best to have intercourse after the removal of the incision wire, which is the best choice.
