Excessive sweating can be caused by anything physical or psychological in the body. One of the first things that come to mind is stress and anxiety. Stress can a number on the body for sure. Not only can it cause excessive sweating, but also tremors, upset stomach, diarrhea, headaches, and even trouble swallowing.
It is not always easy to get a handle on anxiety problems depending on what the cause for the anxiety is. Other than life events, it can be caused by taking amphetamines, dependence on nicotine, street drugs, and certain types of other medications such as drugs to control ADHD.
Resolving whatever the cause of the anxiety is, should help the excessive sweating problems a person is having.
Hypoglycemia, which is low blood sugar can cause a person to sweat buckets. This is often true for diabetic people on insulin. When too much insulin is taken or secreted in the body, low blood sugars can not only cause excessive sweating, but shaking, and the feeling of blacking out which does happen if not treated right away. Diabetics need to always be aware of this, and keep a close check on their blood sugar levels for this reason.
Viral gastroenteritis can cause a person to sweat excessively too. Viral gastroenteritis is where the stomach has an inflammation in it along with the intestines that makes a person feel very sick. Other symptoms of viral gastroenteritis are feeling of unwellness, blood in stools sometimes, profound weight loss, and pain in the lower right portion of the abdomen.
Treating viral gastroenteritis involves dietary changes until the symptoms pass, plenty of liquids to prevent dehydration, and resting as much as possible. Resting will give the body a chance to recover and build the immune system back up.
Menopause in women that no longer menstruate, (usually mid 40's or older,) causes hot flashes. So sweating may be profuse, along with mood changes, insomnia, depression, headaches, and drying of the vaginal area.
Treating menopause usually involves giving hormone replacement therapy, (estrogen,) and also progesterone. Hormone therapy usually balances out the symptoms of menopause altogether.
Motion sickness is also a cause for excessive sweating. Other symptoms of motion sickness include nausea, vertigo, and rapid shallow breathing. Vomiting may also occur. Some people cannot handle taking long trips where they are in constant motion in any form of transportation. A lot of it has to do with the nerves and equilibrium which brings on feelings of illness. This is a very common problem.
A very serious cause of excessive sweating is also an oncoming heart attack. An oncoming heart attack will not only cause excessive sweating, but nausea, feelings of a weight on the chest, and light-headedness. If these are ever your symptoms, it is best to seek emergency help at once.
