Sweating is disliked by many, mainly due to the reason that it releases an unpleasant odor. Some people sweat due to workouts, running, rise in temperature, or other reasons. But some people sweat without the presence of any such factor. This excessive sweating is known as hyperhidrosis and is a common condition with no other side effects other than losing water. Let us look at the medical causes of excessive sweating.

1. Heart diseases
If you have begun sweating a lot either during the day or at night, it might cause an underlying heart disease. Doctors claim that blockages in hearts or arteries are reflected through excessive sweating because it takes more energy to pump blood when the pathway is blocked. Sweating helps the body cool down when the temperature has increased as a result of increased pressure.

2. Cancer
Research is not yet conclusive of why those suffering from cancer sweat excessively, but it is a common sign of cancer. Some suggest that your body is at constant war with your cancer cells, making it work harder to keep you healthy. Fever due to cancer is also a common cause of excessive sweating. Another reason may be the fluctuating hormonal levels in your body.

3. Over or underactive adrenal gland
Tumors in the adrenal glands can also cause excessive sweating. Pheochromocytoma, a harmless tumor that occurs in the adrenal glands, has multiple symptoms like sweating. It also causes anxiety, chest pain, and increased blood pressure- all of which are related to high levels of sweating.

If you’re facing any of these symptoms, it may be wise to consult your doctor immediately.

4. Hyperthyroidism
Hyperthyroidism is directly linked to excessive sweating. Having thyroid conditions such as hyperthyroidism translates to the production of more heat and changes in hormonal levels. Your body will produce even more heat to regular the irregular hormonal levels. Therefore, if you’re experiencing times of increased energy, weight loss, etc., it may be time to consult your doctor and get checked for hyperthyroidism.

5. Mini-stroke
A mini-stroke is also known as a Transient ischemic attack (TIA) in medical terms. Excessive sweating may be caused due to TIA.

In this condition, a certain region of the brain may lose blood supply for only a certain period. The portion that this area of the brain controls may lose control and stop functioning entirely for that duration. However, after a certain period, the brain regains the blood supply and starts functioning normally. This is TIA. If you have faced any symptoms like this, consult your doctor immediately.

So, this was our take on the medical causes of excessive sweating. Even though sweating in itself is a controllable and harmless process, it can be a predictor of some severe and grave underlying factors.
