Doing surgery bedridden for twenty days there is a possibility of muscle atrophy. 1. After surgery, due to the disease itself or surgical trauma, generally need to be braked or recuperated and bedridden after surgery, the muscle fibers do not get normal stress stimulation, the blood supply to the muscle tissue is insufficient, resulting in muscle tissue proteolysis, the elasticity of the muscle fibers decreases, resulting in wasting muscle atrophy. 2. Poor appetite, poor diet, slow gastrointestinal peristalsis during bedridden period, resulting in dystrophic muscle atrophy. 3. Modern medical care advocates early rehabilitation intervention, post-surgery patients should be early passive rehabilitation training and physical therapy, such as passive stretching of the limbs, joint extension and flexion exercise, massage, electrical stimulation, etc., through the local isometric contraction of the way or the method of physical therapy, to prevent the emergence of muscle atrophy. 4. Need to balance the factors, appropriate more supplement high-quality protein such as beef, chicken breast, etc., to promote the body trauma repair; eat more fresh vegetables and fruits, help intestinal peristalsis, promote digestion. If the patient’s muscle atrophy symptoms are serious, or the symptoms continue without improvement, should promptly go to the hospital for treatment.
