  Estrogen plays an important role in maintaining bone structure and density. When estrogen levels decrease, such as after menopause, the risk of osteoporosis and bone loss rises 8th . Low estrogen levels can lead to porous, weakened bones and osteoporosis 6 .   The majority of postmenopausal females with osteoporosis have bone loss related to estrogen deficiency. The rapid bone loss results from an increase in bone turnover with an imbalance between bone resorption and bone formation 4 . At a cellular level, several mechanisms contribute to the bone loss related to estrogen deficiency. Estrogen affects bone cells, including osteocytes, osteoblasts, and osteoclasts. The lack of estrogen ages the expression of estrogen target genes, increasing the secretion of IL-1, IL-6, and tumor necrosis factor (TNF). Studies have also shown that estrogen deficiency directly affects cell differentiation and apoptosis. The net effects of estrogen deficiency are increased bone turnover and enh...

  Estrogen is the primary hormone that sets women apart from men. While men have it in small amounts, women have far more. Estrogen is responsible for maintaining vaginal blood flow and lubrication, thickening the lining of the uterus during the menstrual cycle, preserving bone density, and playing an important role in sexual development and fertility 1 9 12 . Causes of Estrogen Deficiency The most common cause of low estrogen is age. It’s natural for estrogen levels to fall as women get older. Low levels unrelated to menopause may be a sign of a condition such as eating disorders, genetic conditions, autoimmune diseases, or primary ovarian insufficiency 2 9 .  Other factors that can cause low estrogen levels include excessive exercise, disordered eating, or complications with the ovaries 13 . Symptoms of Estrogen Deficiency Symptoms of low estrogen levels range from mild to severe and can include: Breast tenderness Fatigue and sleep issues Irregular menstrual cycles Disappear...
