If you’re always sweating, you might be wondering why it’s happening to you. You notice that you have heavy sweating even when you’re sitting still in a cold room. Your friends and family don’t sweat like that. So, what’s the cause of excessive sweating for you? Well, it could be one of the following health conditions.

Some types of cancer

As scary as it sounds, some cancers could be the cause of excessive sweating. The types of cancers potentially causing the constant sweating include Non-Hodgkin’s lymphoma and Hodgkin’s lymphoma, carcinoid tumors, leukemia, mesothelioma, bone cancer, and liver cancer. Many doctors don’t fully understand why some cancers are the cause of excessive sweating, but it might be connected to the body trying to fight off cancer.


Hyperhidrosis is a very common cause of excessive sweating. In fact, there are eight million Americans with hyperhidrosis, and they sweat four to five times as much as the average person. This sweating condition is broken into two subtypes, either primary or secondary hyperhidrosis. Primary hyperhidrosis doesn’t have a clear cause, but it is thought to be hereditary. Secondary hyperhidrosis is typically caused by other medical conditions and medications.

Certain medications

Some medications can cause people to sweat excessively. Medications for high blood pressure, psychiatric drugs, medicines used to treat dry mouth, and some antibiotics and supplements can all cause excessive sweating. If you think your medication is causing you to sweat excessively, then you need to consult your doctor.

Glucose control disorders

Glucose control disorder includes diabetes type 1 and type 2, gestational diabetes and hypoglycaemia (abnormally low glucose levels). Excessive sweating is a symptom of having low glucose levels.


Many women going through menopause report suffering from hot flashes. In fact, 75% of women say they experience hot flashes and sweat a lot during menopause and the time leading up to it. In some women, the hot flashes are so severe that they have to change their clothes. These hot flashes and sweating problems during menopause are thought to be caused by fluctuating estrogen levels.

The cause of excessive sweating is often unknown for many suffering. Fortunately, though, a visit to your doctor can help you figure out why you’re sweating so much.
