Many people with diabetes find out that they have a diabetic foot when they are already in the middle or late stages, because they still do not know enough about it. What are the early warnings of diabetic foot? 1. Petechiae on the legs or feet: Due to poor blood circulation in the lower extremities, blood flow slows down and blood penetrates the skin, which leads to purplish skin on the feet and legs, forming petechiae or purple patches. 2, skin itching, scratching and breaking: itchy skin symptoms appear on the legs, some itching is very stubborn, so unconsciously scratching the skin, resulting in skin breakdown, ulcers apply compound edge cream to penetrate the subcutaneous repair damage, while paying attention to prevent the spread of germ infection and inflammation. 3, the appearance of eczema or rash: because the skin tissue glycogen content is also increased, creating a good environment for the infection of mold and bacteria, easy to produce eczema and rash and other skin infections. 4, dry and flaky skin, thickened toenails: diabetic patients due to neurological and vascular lesions, legs and feet due to lack of moisture and thus dry and flaky, may appear dry cracks or blood blisters, toenails will also become yellow and thick. 5.Foot sensation fading: feeling numbness in both feet, stepping on the ground like stepping on a quilt, walking unsteadily, and due to limb ischemia or neuropathy, there will be painful and burning sensation. 6, intermittent claudication: due to insufficient blood supply to the lower limbs, walking is easily sore, and intermittent claudication will also occur, requiring frequent rest to recover. 7, joint deformation: Due to the lesion of the nervous system of the foot, the muscles and bones of the lower limbs will change, showing joint deformation, and due to malnutrition of the extremities, muscle atrophy will also occur, showing a gradual thinning of the lower legs. The causes of diabetic foot occur in two categories, one is due to lower limb ischemia caused by lower limb artery occlusion, ulceration or gangrene of the skin of the legs and feet; the other is lower limb neuropathy caused by hyperalgesia or loss of sensation, diabetic foot is one of the complications of diabetes, understanding the early warning of diabetic foot can help early protection and treatment. In addition, after all, the treatment of diabetic foot itself is very complicated, we suggest that you go to MDT multidisciplinary joint treatment center to receive treatment, so that the treatment is more comprehensive and the effect is guaranteed.
