Foot odor, also known as tinea pedis, is a very common foot skin disease caused by a fungal infection, but many people who suffer from foot odor do not see it as a disease and feel that foot odor is not very harmful and that it is nothing if it is itchy, which is a very wrong viewpoint. 1, foot odor can seriously affect the quality of life of people. People suffering from foot fungus will produce severe itching, the more you scratch the more itchy, hate to use a knife to scrape, once the skin is broken, it is easy to induce infection. If the itching occurs on an important occasion, you can’t just take off your shoes in public and scratch wildly. 2, foot odor has a strong contagious, will inevitably affect the health of the family, so the prevention of foot infection should not be underestimated. Because patients do not pay enough attention to the disease, often leading to one person, the whole family infection. Serious foot fungal infections are also closely related to diabetes, vascular diseases and other systemic diseases. Foot odor is because the sweat glands of the feet are well developed, sweating more, in a humid and warm environment, resulting in the unbridled breeding of bacteria and fungi. 3, foot odor can also be secondary to other parts of the infection. If treatment is not active, scratching can easily lead to fungal infections in other parts of the body, such as ringworm, ringworm, and ringworm of the head. More seriously, scratching can lead to local bacterial infections that can develop into lymphangitis, cellulitis, and dermatitis, which can have endless consequences. Fungi are ubiquitous in nature, they are very strong, not afraid of cold, light and dryness, even if they leave the body for months or even years or decades, they do not necessarily die. A survey of “patients with skin fungal infections and their family members” found that 85.4% of patients and their family members were infected with the same disease-causing fungi. This figure is strong evidence that the possibility of spreading the fungus among family members is very high, especially for children and the elderly who are less resistant and more contagious. If you suffer from foot fungus, you should treat it promptly and early, adhere to the treatment, and do not use drugs indiscriminately in order to treat it effectively.
