What are the Causes of Hot Flashes?

Hot flashes arise due to the following causes.

1. Menopause

Hot flashes are ordinarily caused by changing hormone levels that occur prior to, during and following menopause. The reasons as to why hormonal changes give rise to hot flashes have not been made clear thus far. That being said, research indicates that hot flashes arise when reduced estrogen levels cause the body’s hypothalamus to become more sensitive to minute changes in body temperature. Once the hypothalamus begins to think your body is too hot, it sets forth a series of events (that constitute a hot flash) in order to cool you down. It is rare for hot flashes to be caused by something other than menopause.

2. Side effects

Certain medications can give rise to hot flashes.

3. Thyroid-related problems

When the thyroid gland produces either too much or too little of the thyroid hormone, it can result in hot flashes.

4. Certain kinds of cancer

5. Side effects of cancer treatment

In a bid to treat cancer, you can end up experiencing hot flashes.
