A unified survey of diabetic foot patients in 14 tertiary hospitals in 14 cities in China found that physical factors accounted for 60% to 80% of the various triggers of diabetic foot. According to the experts in charge of the study, 15-20% of diabetic patients have foot ulcers or gangrene (commonly known as diabetic rotten feet) during the course of the disease, and the probability is 40 times higher than that of ordinary people. About 10% of diabetic patients will end up with foot ulcers due to abnormally high plantar pressure during the course of the disease. The main reasons for increased plantar pressure in diabetic patients: 1. Diabetic neuropathy: When diabetes occurs in the human body, the metabolic disorder causes a reduction in nerve fibers, which causes atrophy of the small muscle groups in the foot. Foot muscle atrophy directly cause foot flexion and extension imbalance, motor neuropathy damage at the same time also involves the autonomic nerve, so that people suffering from diabetes feel dry foot skin, foot muscle atrophy, no sweat, serious can cause heel cracking, thus causing a significant increase in plantar pressure. 2, limited joint movement: joint movement is also an important reason for the increase in plantar pressure in diabetes, in the normal gait walking process, the flexibility of the joints of the foot can ensure that the correct foot on the ground walking, posture is smooth, in walking to maintain a stable and strong, can buffer the shock, if the autonomic and motor nerve lesions, directly affect the stability of the walking process, and lead to a decline in buffering capacity, caused by increased plantar pressure. 3, overweight: human feet, is the positioning point of the whole body, especially the heel and the first five metatarsophalangeal joints, is the best support point for the human body to stand, walk, if the weight is too heavy, the pressure on the foot will invariably increase. 4, increased plantar keratinization: If the plantar keratinization increases, the heavy formation of calluses, calluses directly increase the pressure load, thus causing increased pressure on the foot. Effective ways to relieve plantar pressure: 1, foot massage: every morning after waking up and before going to bed at night, soak your feet with warm water for 10 minutes, rub your feet with both hands for 10 minutes, from the toes to the back of the foot, the heart of the foot, the heel in the direction of rubbing, and then rub in the opposite direction. This can effectively improve foot blood circulation, adjust the motor nerve, prevent muscle atrophy, reduce plantar pressure, thus preventing the occurrence of foot ulcers. 2, reduce weight: minimize the body’s excess weight, can effectively reduce the pressure on the soles of the feet, so as to effectively prevent the occurrence of diabetic foot ulcers. 3.Prevent keratosis of the bottom of the foot: eat more vitamin-based food and medicine, for footwear must be comfortable and appropriate, not too squeezed, to prevent frostbite, cracking, so as to effectively prevent the occurrence of diabetic foot ulcers. 4, preventive surgery treatment: should be regularly checked by orthopedic surgeons to see if there are deformities in the foot bones, joint movements and gait imbalances, because these can lead to injuries to the landing place of the foot. It has been found that nearly half of the foot ulcers are concentrated in the big toe, which may be related to the high pressure load on the first toe, so the plantar peak pressure can be reduced by performing metatarsal head resection and decompression surgery. Prophylactic metatarsal head resection or metatarsal head osteotomy and elevation may also be performed to reduce plantar pressure in patients with non-infected and ischemic diabetic plantar ulcers. The increase in local plantar pressure is an early predictor of plantar ulcers, so it is important to evaluate the plantar pressure level objectively at an early stage. Diabetic neuropathy, restricted joint movement, and callus are important common causes of increased plantar pressure in diabetic patients, and pressure relief measures should be taken actively and effectively to prevent ulcer formation in diabetic foot is very important. Therefore, strengthening the publicity and education of diabetic foot disease, improving the awareness and ability of diabetic patients to take care of themselves, and regularly checking the plantar pressure can effectively prevent the occurrence of diabetic foot ulcers. Experts remind patients that if conservative treatment does not work well, they should seek early consultation with a specialist to prevent further deterioration. In addition, in the pre-surgical period and after the surgical treatment, it is necessary to cooperate with medication and, most importantly, to control blood sugar.
