Self-care of the diabetic foot begins with avoiding abnormal foot conditions, including blisters, cuts, redness, hardening, breakouts, abrasions, localized heat, localized coldness, and any other changes that look bad. Choosing the right footwear and foot care practices is essential to prevent foot injuries. For problems like blisters, cuts, ingrown toenails and changes in the shape or color of the foot, be sure not to handle them blindly on your own, you need to consult a professional doctor. 1, it is recommended to soak your feet in warm water every day. Since most diabetic patients have varying degrees of foot neuropathy, their ability to sense temperature is reduced and they cannot perceive the temperature correctly, so they should first use their hands or a thermometer to sense the water temperature. The temperature should be lower than 37 degrees. Do not use hot water to scald the feet. Soak feet should not be too long, the foot skin fissures, and not soak for too long, so as not to avoid the invasion of bacteria by the fissures soaked through the tissue. After washing both feet, should be gently wiped with a soft dry towel, especially between the toe seam moisture must be dried. Autumn and winter season foot skin is prone to dryness and cracking, it is recommended to evenly apply some moisturizer, but not between the toes. After washing, you can massage the lower extremities to promote blood circulation in the lower extremities and improve local symptoms. Do not use hot water bags or hot water bottles to warm your feet. If your feet are cold, you can put on socks or cover with a blanket. 2.Correct toenail trimming. Wash and dry your feet and then trim your toenails carefully with scissors, don’t trim them too short, keep a certain distance from the edge of the skin and grind the edges smooth to be careful of damaging the skin. If you can’t do it yourself because your toenails are too thick or you can’t see clearly, you can ask your podiatrist to trim them. 3, treat corns and calluses gently. If the doctor says it’s not a problem, you can use a grinding stone to gently smooth it out. Never use corns water, callus remover or corns cream, and do not use a blade to cut and scrape. Do not deal with warts on your own when they grow, but go see a doctor. 4, choose the right shoes and socks. Daily use shoes, shoes should be soft, breathable, moderate size, wide toe. Choose flat-soled shoes. It is best to have round toe, lace-up leather shoes. If work allows, walking shoes are a good choice. Avoid small shoes with hard soles and high heels to prevent restriction of foot movement. Don’t buy shoes with high heels or pointed toes (which concentrate pressure on the toes) or polyethylene or plastic shoes (because they don’t breathe and don’t fit the foot). When exercising, wear athletic shoes. Keep the inside of your shoes hygienic and wash the soles and socks regularly. Keep the inside of your shoes dry to actively prevent foot odor. Socks should be made of cotton as much as possible, which is both sweat-absorbent and breathable. Don’t make the socks too tight at the edges to avoid strangling marks on the socks. Do not wear socks that are gartered or too tight, and do not tie elastic bands around your legs. Wear shoes and socks even inside the house. Have slippers by your bedside to wear when you get up at night 5. Before putting on shoes, check if there are any pins, coins or small stones in the shoes that may hurt your feet. 6.Change and wear clean socks every day, and throw away worn-out socks or socks with worn linings. 7.Go shopping for shoes at night, because that’s when your feet are the biggest. When you try on shoes, put on your thickest socks with padding so that you can be sure that the socks fit properly in the shoe. Feel the inside of the shoe to make sure there are no wrinkles or hard seams. Be sure not to hope that the shoe will be worn large; it should be a proper and comfortable fit to begin with. 8. Get used to the new shoes gradually. Wear them for only one hour on the first day, then check your feet carefully. 9.The special shoes or insoles specified by the doctor should be worn every day, and put in the shoe closet will not play a protective role.
