There are those that suffer from a condition known as Hyperhidrosis. This little understood condition seems to kick the sweat glands into high gear, especially where they are concentrated, such as in the face and head, under the arms, the back, hands and feet. Generally speaking it only affects one of these areas on a particular individual. Secondary Hyperhidrosis is sweating caused by an underlying cause. It could be caused by such things as an illness, like diabetes, or it could be because of hormonal or glandular problems. The victim of this problem usually experiences excessive body sweating, which is not always confined to one particular area.
