Low estrogen levels can happen in young women for a number of reasons. They could be due to a low body fat level, an eating disorder or a total hysterectomy. As the "master gland," the pituitary gland regulates hormone levels, including the amount of estrogen in the system. The signs and symptoms of low estrogen levels in young women can be divided up into three categories: physical, psychological and sexual.
There are many physical symptoms associated with low estrogen levels in young women. Some of these signs include low bone density (which can lead to an increased risk of osteoporosis or bone fractures), hair loss, facial hair, hot flashes, cold chills, night sweats, sore breasts, palpitations, indigestion, flatulence, bloating, low back pain, joint pain, headaches, dry skin and weight gain.
Some women may experience psychological symptoms along with the physical ones. Some of these symptoms may include depression, nightmares, panic attacks, mood swings, irritability, inattention and memory lapses.
Low estrogen in young women can affect the sexual organs. These symptoms may include painful intercourse, absent periods, no libido, vaginal itching and vaginal dryness. Hormone replacement therapy can help to raise both progesterone and estrogen levels but must be weighed against the risk of breast or uterine cancers, blood clots and/or dementia if used over the long term.
