Estrogen is a growth hormone responsible for the development and maintenance of the female reproductive system. It is released in high amounts during the follicular phase of the menstrual cycle which is the first 2 weeks leading up to ovulation. Estrogen is released from the ovaries, fat tissue, and adrenal glands because it has a connection between fertility and body fat composition. The main functions include building up the uterine wall for the menstrual cycle, stimulating the growth of the egg follicle, developing breast tissue, stabilizing bone density, and controlling the metabolism of glucose and lipids.
Imbalanced levels of estrogen can be harmful because it can cause irregular periods,
tender breasts, PMS, bloating, constipation, anxiety, mood swings, and headaches. Over time, these symptoms can worsen and in some cases can lead to hormonal cancers. Estrogen and progesterone work on a balance, where a high level of one will cause a low level of the other. Here are the 3 patterns: high estrogen and normal progesterone, high estrogen and low progesterone, normal estrogen, and low progesterone. You never want your estrogen to be too high or too low because all your hormones work on a balance, and when one goes too high/low then other hormones have to make up for it.
