What is the cause of chilblains on the foot?

Chilblains are problems that occur on the foot which are more prevalent in the wintry environments. Understanding the explanation for any disorder will go some distance to help understanding what is occurring with them, how to prevent chilblains and the ways to deal with them. This is certainly true of chilblains. While they only occurs in cold environments, they are not really caused by the actual cold. Many people who do not have them get cold as well and they usually do not have chilblains. Likewise, some individuals get chilblains with even little alterations in temperature and it not being too chilly. Because of this there is lots more occurring than just the cold that usually gets held responsible for resulting in them.

Within the skin there are a lot of small blood vessels (the microcirculation) which help normalize temperature in your body. Whenever we become cold, those arteries constrict to conserve heat deeper in the body. When we are warm, these capillaries open up and convey the blood closer to the surface so that we are able to disperse heat for cooling the body. It is deemed an essential normal functionality. In a chilblain the capillaries close up like they usually should, but when the feet are warmed up, the arteries stay closed when they shouldn't be. Because of this waste material begin to accumulate within the skin and there's no blood flow to get rid of them. This will cause an inflamation related response along with the release of chemical substances making the chilblain painful and also itchy. Sooner or later the capillaries will open up and the rapid rush of blood to the area causes even more irritation and pain. The primary appearance is usually a darker blue patch, however it could be a reddish look following that rush of blood. If the malfunction is frequent on a daily basis, then chilblains can be transformed into a significant chronic lesion.

Exactly the reason why in some individuals the blood vessels stay constricted for longer in cooler environments in not known. Chilblains are more common in females, indicating that there could be some type of hormone imbalances affect on the pathology. However, males do can also get them, so if it is hormonal linked, then that isn't the sole factor. Interestingly for a thing that is so common, there is certainly relatively little research been done to attempt to look into chilblains in greater depth.

Applying this information about what's causing chilblains might help individuals prevent and treat them. Obviously the first thing to do will not be let the feet get cold whilst keeping them warm. If they do become cool, then it is very important that they are warmed up quite gradually so that the microcirculation to have a chance to respond to the higher demand in the skin and the arteries will open up to meet that demand. This means that the waste products will not accumulate and the inflammation process is not started. When that pathology does start, then your course of treatment has got to move to minimize that inflammation process and help dispose of those waste material which have built up in the skin.
