3. Hot Flushes
In most cases, women will not experience what is known as hot flushes until after their periods have stopped coming altogether. However, this is not an absolute rule and there may be exceptions in certain cases. The feeling of hot flushes is most often described almost like a fever which occurs rapidly, with no environmental cause necessary such as being in a hot room, and the effects can be either mild or severe. If it is associated with early menopause then it is more likely to be severe.
These hot flushes are almost always due to the fact that estrogen levels within the body will fall rapidly after the point at which the monthly periods have stopped. The rapid fall in estrogen levels is also the cause for most other symptoms that may be experienced by women going through menopause, whether it is at an early age or the average age for onset.
