was ist östrogen — what symptoms are typical?

Estrogen is a primary female sex hormone produced mainly in the ovaries, but also in smaller amounts in males. It regulates the menstrual cycle, fertility, and influences many other bodily functions such as bone density, skin elasticity, and mood. Typical symptoms of estrogen deficiency occur primarily during menopause: hot flashes, night sweats, vaginal dryness, sleep disturbances, mood swings, and reduced libido. Estrogen excess (estrogen dominance) can manifest as water retention, breast tenderness, migraines, worsened PMS symptoms, and an increased risk for certain cancers (e.g., breast cancer). However, symptoms vary greatly between individuals and can be influenced by other factors like stress, diet, or thyroid function. A blood test can clarify hormone status, but estrogen levels alone are not always conclusive – the ratio to progesterone and the individual symptom profile are crucial. If an imbalance is suspected, medical evaluation is recommended before taking any action such as hormone replacement therapy or natural regulation through diet and exercise. Evidence for these symptoms is strong and based on decades of clinical observation and research.
