The precautions to be taken after circumcision anastomosis include paying attention to physiological hygiene, avoiding sexual life, improving daily diet and so on. 1. Pay attention to physiological hygiene: after the operation, we must pay attention to physiological hygiene, change underwear diligently, keep the lower body clean, and in the process of urination, avoid soaking the surgical incision with urine, so as to avoid infection of the surgical incision site. 2. Avoid sexual life: Before the incision is completely healed after the surgery, you should prohibit sexual life, and do not frequent contact with sexual stimulation, to prevent repeated penile erection, because when the penis is erected, it may pull the surgical incision, which will easily affect the healing of the surgical incision site, and may even cause the incision to bleed, crack, and so on. 3. Improve daily diet: After the surgery, you should adjust your daily diet structure, eat a light diet, eat more fresh vegetables and fruits, avoid eating stimulating food, and do not drink alcohol and smoke.
