Ans: When women have low levels of estrogen in their bodies, there are a lot of problems that can occur. Some of these issues include irregularities in the menstrual cycle, mood swings, hot flashes, thinning as well as dryness of the vagina and much more. That is one of the main reasons why women choose estrogen tablets uses in order to increase their levels of estrogen in the body. Apart from that, having higher levels of estrogen than normal can lead to problems in women such as weight gain, menstrual issues, fibrocystic breasts, fatigue, PMS, loss of sexual drive, fibroids, and much more. Consulting with a gynecologist during such times can be a good idea.
