Tinea pedis is a condition known by its scientific name “Tinea pedis”. Tinea pedis is a pathogenic fungal infection of the foot, often found in the toe crevices. It is caused by sweaty, damp feet, impermeable shoes and socks, and poor evaporation of sweat, which can lead to fungal infections. Diabetic foot is a local lesion caused by diabetic peripheral vasculopathy, diabetic peripheral neuropathy and infection. Infection may be an independent risk factor for the development of diabetic foot or a contributing factor for the development of diabetic foot. Diabetic patients have disorders in the metabolism of sugar, protein, and fat, and their immunity decreases. The sugar content of the patient’s skin tissue increases, the barrier effect of the surface sebum is destroyed, and the antibacterial ability decreases, making it easy to contract fungal infections at this time. Although diabetics are prone to tinea pedis, a simple tinea pedis is not a diabetic foot; for diabetics, this “little” tinea pedis can lead to a diabetic foot if left untreated. The fungus can spread to other parts of the patient’s body and cause other skin conditions such as ringworm, ringworm, and nail fungus (commonly known as gray nails) because it is not taken seriously, and can also cause itchy scratching that leads to skin breakdown, as well as complications with bacterial infections that can lead to lymphangitis, lymphadenitis, and dermatitis, which can cause diseases such as diabetic foot, or even sepsis, which can be life-threatening or lead to amputation. Now that summer has arrived and the weather is humid and hot, the incidence of tinea pedis (foot fungus) is not far away if the shoes and socks are not breathable or if we do not pay attention to the hygiene of our feet, so we should pay attention to the following points to minimize the occurrence of tinea pedis, prevent infection, and reduce the transformation of foot fungus into diabetic foot. To prevent the occurrence of athlete’s foot and to reduce the infection of athlete’s foot, you should pay attention to the following: 1. Pay attention to foot hygiene: wash your feet every day and wipe them clean with a soft, clean towel after each wash to keep the fungus from having a home. 2, wear loose, comfortable, breathable and sweat-absorbing socks and shoes: although breathable, but it is not recommended to wear sandals barefoot, do not play barefoot, so as not to stab the foot. Shoes and socks should often sunbathe, so that fungus can not breed. 3, towel dedicated: must pay attention to the towel dedicated, not mixed with other people, and not mixed slippers, for friends and relatives with foot odor also do not because of the affection within the mixed shoes. Towels should often be hot with boiling water, and often sunlight. 4, do not scratch when itchy foot seams, so as not to break the skin. Skin breakage will also be easy to combine bacterial infection. 5, if there is foot odor, go to the hospital in a timely manner, do not use drugs on their own. Pay attention to the local situation at the same time, but also pay attention to the control of blood sugar, high blood sugar is the medium, lower blood sugar can effectively improve the skin barrier role, in order to really reduce the fungal infection.
