Diabetic foot is one of the complications of diabetes, commonly known as diabetic foot rot. It is the joint effect of peripheral neuropathy and peripheral vascular disease formed by diabetes for a long time, and it is the ulceration and gangrene that appear in the foot. Diabetic foot does not mean that it is very serious as soon as it appears. It has a development process, that is, from the early symptoms to the later severe diabetic foot. To put it bluntly, when the diabetic foot appears, the patient is If there are certain pre-symptoms, in order to let more diabetic patients know that it has appeared early, let's talk to the patients about the early symptoms of diabetic foot. I hope that patients can pay attention to it:
the four major diabetic foot attacks Signals:
1. Feeling dullness of the feet, and the pathological changes of the nerves of the lower limbs when the feet are stepped on cotton wool, which will cause the patient's lower limb skin to appear dry due to non-sweat, and the extremities will be accompanied by tingling, burning, numbness, or even dullness or sensation. Loss is characterized by sock-like changes, or a feeling of stepping on cotton wool, and even deformities on the feet.
2. Dry skin, hyperpigmentation, and muscle atrophy of the lower limbs. Due to malnutrition, the muscles atrophy and the skin becomes dry and elastic. Skin temperature will also decrease, and skin pigmentation will appear. The arterial pulsation of the lower extremities will weaken or disappear, and blood vessel murmurs may be heard at the stenosis of the blood vessels.
3. Inconvenient walking, intermittent claudication and rest pain are intermittent claudication in the early stage, which is mainly caused by mild ischemia of the lower extremities. After walking for a certain distance, the lower extremities begin to show weakness and numbness. Its characteristic is that after stopping walking or resting, the symptoms of weakness and numbness of the lower limbs are alleviated. But when the ischemia worsens, rest pain will appear. Resting pain is also pain when walking or not exercising at rest. It mainly occurs on the toes or the distal end of the foot. It has the characteristics of aggravating at night, aggravating when lying down, and being relieved by keeping the lower limbs drooping.
4. The most common site for extremity ulcers and gangrene ulcers is the bottom of the forefoot, which can generally be divided into neuropathic ulcers, ischemic ulcers and mixed ulcers. Neuropathic ulcer: mainly caused by neuropathic disease. This type of ulcer has good blood circulation, so the foot is generally warm and dry, and the pain is not very obvious. Local tissue skin erosions, with more secretions; Ischemic ulcers: foot ulcers caused by simple ischemia, skin and dry, darkened, no secretions, no edema; mixed ulcers: both peripheral neuropathy and There is peripheral vascular disease, which contains the symptoms and characteristics of both.
