High oestrogen levels can have very negative health consequences. Oestrogen dominance plays a big role in conditions associated with hormone imbalance such as Endometriosis, Fibroids, Polycystic Ovarian Syndrome (PCOS) and Premenstrual Syndrome (PMS). Aesthetic conditions would include Melasma, Acne, Cellulite and weight gain.
In men, high oestrogen levels can cause the growth of breast tissue (gynecomastia), enlarged prostate, and erectile dysfunction especially in males with excess abdominal fat. High oestrogen levels also increase the risk for hormone-sensitive cancers in both men and women.
