Diabetic patients have a relatively slow response to the nerves in the foot compared to normal people, and lack of neuroprotective reflexes, so it is not easy to detect the injury, which can easily lead to infection and even ulceration and cause diabetic foot. Therefore, diabetic patients should pay attention to the cleanliness of foot hygiene, timely trimming of toenails can reduce the breeding of bacteria under the nail, as well as prevent accidental injuries caused by overly long toenails. Correct toenail trimming is very important for diabetic foot patients. 1, the correct way to trim the toenail is to cut the toenail flat, and then use the thumb on the toenail cutter to thwart both sides of the toenail to prevent the foot fat nail on both sides of the foot will be cut. 2, never trim both sides of the toenail in particular: many people like to trim their toenails round, and if the toenail length is insufficient, they tend to trim to both sides of the toenail. This time the toenail and the side of the nail wrinkle (that is, the side meat next to the toenail) will produce a gap, the mother cell of the toenail detects this message, the next time the toenail will grow a little more to the side, and the formation of toenail embedded (ingrown nail disease), causing serious pain reaction! At this point, patients tend to trim this area in particular, forming a vicious cycle. In fact, you should quickly rub anti-inflammatory and anti-swelling creams to avoid trimming this area. To avoid ingrown toenails, pulling out the toenail is not a permanent solution, start by cutting the right toenail! 3, toenail do not stay too long: stay too long toenail, toenail is often easy to unknowingly hook to something, and cause injury between the toenail and nail bed, toenail and nail bed separation, due to hook to sometimes there is no obvious pain response, resulting in patients injured without knowing, but the toenail has the ability to repair, as long as no longer injured, the separation will slowly solve the situation. However, if the toenail is repeatedly hooked without being aware of it, it will be very difficult to recover from repeated injuries. So it is advisable not to keep your toenails too long! 4, be patient: fingernails grow 0.1 centimeters per week, toenails grow more slowly, one-third only, so the correct trimming of toenails, but also patience, the results will be obvious!
