How does frostbite form?

There are many common problems in life. When solving some problems, good methods are also needed. Among the common problems, diseases have the greatest impact on people. Such problems have serious damage to all aspects of the human body. Moreover, if the disease is not treated in time, it will cause the body to become weak and induce other diseases. So how is frostbite formed?

Frostbite is a very common disease. This type of disease does not cause much harm to human health, but if it is not treated in time, it will cause the body to have a fever. So how is frostbite formed? It also has some reasons.

How frostbite is formed:

Cold is the main cause of frostbite. The cause of the disease is that when the skin of frostbite patients encounters cold (0-10℃), humidity or sudden changes in temperature, the local small arteries contract, and over time the arteries become paralyzed and dilated, causing venous congestion and poor local blood circulation, leading to the disease. In addition, factors such as the patient's own skin moisture, peripheral microvascular malformations, autonomic nervous system dysfunction, malnutrition, and endocrine disorders may also contribute to the onset of the disease. Lack of exercise, excessive sweating and dampness of hands and feet, tight shoes and socks, and long-term outdoor work in low temperatures can all lead to frostbite.

Chilblains are common in early winter and early spring, and are more common in children, women and people with poor peripheral blood circulation. These patients often have symptoms such as cold skin on the extremities, cyanosis of the extremities, and excessive sweating. Skin lesions often occur on the fingers, back of hands, face, ears, toes, edges of feet, heels, etc., and are often distributed on both sides. Common lesions are localized congestive dark purple-red raised edematous erythema with unclear boundaries, bright red edges, tense and shiny surface, and soft texture. Local pressure may cause the color to fade, and the red color will gradually return after the pressure is removed. In severe cases, blisters may occur, which may rupture to form erosions or ulcers, and may leave pigmentation or atrophic scars after healing. There is obvious itching, which is aggravated by heat and causes pain after ulceration.

Through the above introduction, we have a good understanding of how frostbite is formed. There are different factors that cause this type of disease, so when treating it, the method must be chosen correctly. However, in the case of this type of disease, medication is the best choice, which is very helpful in improving frostbite.
