Why do I sweat this much and how do I stop it?

For my personal style, I straighten my hair. But it's hard to keep it perfect because I sweat a lot! And I'm not overweight, actually I'm underweight and it's so annoying when I have to walk a normal lenght distance with my friends and I end up completely sweaty... I've tried strong desodorants, small clothes and pony tails to avoid heat but I still can't get rid of this problem. Help please.
Why do I sweat this much and how do I stop it?
You have between 2 million and 5 million eccrine sweat glands. When your body temperature rises, your autonomic nervous system stimulates these glands to secrete fluid onto the surface of your skin, where it cools your body as it evaporates. This fluid (perspiration) is composed mainly of water and salt (sodium chloride) and contains trace amounts of other electrolytes 鈥?substances that help regulate the balance of fluids in your body 鈥?as well as substances such as urea.





Apocrine glands, on the other hand, secrete a fatty sweat directly into the tubule of the gland. When you're under emotional stress, the wall of the tubule contracts and the sweat is pushed to the surface of your skin where bacteria begin breaking it down. Most often, it's the bacterial breakdown of apocrine sweat that causes an odor.





A number of factors can affect how much you sweat as well as your sweat's smell. Certain foods, drugs or medical conditions can cause excessive sweating, whereas drugs or conditions may interfere with your ability to perspire normally.





-Excessive sweating (hyperhidrosis)


Some people sweat more than others for no apparent reason. But some factors may make you sweat heavily. These include:


-Heredity. Some people inherit a tendency to sweat excessively, especially on their palms and the soles of their feet.


Certain foods and beverages. Drinking hot beverages and those that contain caffeine or alcohol can make you sweat. Eating spicy foods can, too.


-Certain drugs. Drugs that can cause excessive sweating include some antipsychotic medications used to treat mental disorders, morphine and excess doses of the thyroid hormone thyroxine. Analgesics, such as aspirin and acetaminophen (Tylenol), also increase sweating.


-Low blood sugar (hypoglycemia). This occurs when the level of sugar in your blood drops below a certain level. It's most common in people with diabetes who take insulin or oral medications that enhance the action of insulin. Early signs and symptoms include sweating, shakiness, weakness, hunger, dizziness and nausea. Some people may develop low blood sugar after eating, especially if they've had stomach or intestinal surgery. In rare cases, your body may produce too much of the pancreatic hormone insulin, leading to low blood sugar.


-Fevers. Fever occurs when your temperature rises above its normal range. You may have a fever with many types of bacterial and viral infections. When your body temperature finally begins to return to normal, known as "breaking of the fever," you may sweat profusely, which is your body's way of dissipating the excess heat. Shaking chills after the fever are your body's attempt to raise its core temperature. Repeated episodes of fever followed by sweating and chills may indicate a serious infection or other illness.


-Overactive thyroid (hyperthyroidism). Sometimes the thyroid gland produces excess amounts of the hormone thyroxine. This can cause a number of signs and symptoms, including weight loss, a rapid or irregular heartbeat, nervousness and increased sensitivity to heat. It may also cause you to perspire much more than normal.


-Heart attack. This occurs when a loss of blood supply damages or destroys part of your heart muscle. The signs and symptoms of a heart attack include pressure; fullness or squeezing pain in your chest that lasts for a few minutes or pain that extends beyond your chest to your shoulder, arm or back; shortness of breath; and intense sweating. If you experience these symptoms, get immediate medical care. Every minute counts during a heart attack.





-The other reasons are malaria, leukemia, menopause, etc which I don't think it is.








Not to freak you out but I think if it's really becoming a problem and you can't live your daily life because sweating so much is embarrassing you, definitely see a doctor. I think it's probably a thyroid problem or diet problem rather than anything else, but only a doctor can really figure out what the problem is, or if there is a problem.
