Signs of hyperestrogenism may include heightened levels of one or more of the estrogen sex hormones (usually estradiol and/or estrone), lowered levels of follicle-stimulating hormone and/or luteinizing hormone (due to suppression of the hypothalamic–pituitary–gonadal axis by estrogen), and lowered levels of androgens such as testosterone (generally only relevant to males). [1]
Aromatase excess syndrome (AES or AEXS) is a rarely diagnosed genetic and endocrine syndrome which is characterized by an overexpression of aromatase, the enzyme responsible for the biosynthesis of the estrogen sex hormones from the androgens, in turn resulting in excessive levels of circulating estrogens and, accordingly, symptoms of hyperestrogenism.
This termination of menses is associated with a dramatic drop in estrogen levels. The estrogen levels stated previously dramatically decrease to approximately 20 pg/ml [5] or less when menopause begins. Menopause falls under the umbrella of conditions related to hypoestrogenism. There are many symptoms associated with the transition and ...
Mild symptoms include abdominal bloating and feeling of fullness, nausea, diarrhea, and slight weight gain. Moderate symptoms include weight gain greater than 1 kg (2.2 lb) per day, increased abdominal girth, vomiting, diarrhea, darker urine, decreased urine output, excessive thirst, and skin and/or hair feeling dry (in addition to mild symptoms).
By using a cell line that contains high levels of estrogen receptors, scientists found that treatment with physiological concentrations of 17 beta-estradiol is associated with accumulation in the conditioned medium of an amino-terminal cleavage product of APP (soluble APP or protease nexin-2), indicative of non-amyloidogenic processing.

The main source of estrogen is the ovaries in premenopausal women, while in post-menopausal women most of the body's estrogen is produced via the conversion of androgens into estrogen by the aromatase enzyme in the peripheral tissues (i.e. adipose tissue like that of the breast) and a number of sites in the brain. Estrogen is produced locally ...
It may also lead to abnormally high levels of androgens, which can cause hirsutism. Overweight or obesity affects over half of women with PCOS. At least 65% to 80% of people with PCOS live with ...
