After kidney surgery, it is recommended to eat a light diet and pay attention to proper protein supplementation. Kidney surgery is now a minimally invasive surgical method, the surgery is not very traumatic and the bleeding is also very little, so it is not necessary to supplement various nutritious substances too much after the surgery, it is recommended to eat a variety of fresh vegetables, fruits, coarse grains and coarse cellulose food. Because the recovery of gastrointestinal function after surgery is not particularly good, supplementing these light diets can replenish the necessary water, vitamins, electrolytes, fiber and necessary energy, which can supplement the normal needs of the human body. Properly supplement protein to maintain the normal metabolism of the body, and do not oversupply a high-protein diet to prevent increasing the burden on the kidneys.
