It is natural for estrogen to fluctuate for women as it guides menstruation on a monthly basis. However, what generates issues is when estrogen levels are excessively lower than normal, causing many unwanted symptoms.
Continue reading to learn about low estrogen levels and what can cause unnatural fluctuations, including hormonal and lifestyle-related triggers.
During the menstrual cycle, estrogen steadily increases during the follicular phase. A spike in estrogen triggers ovulation, where an egg is released from a matured follicle. Afterwards, estrogen levels decline until the next menses.
In adulthood, it is normal for monthly estrogen levels to span from 30 – 400 pg/mL, depending on age and stage in the menstrual cycle. However, most women will experience abnormal drops in estrogen sometime during their lifetime, and these drops can be caused by a variety of factors.
The causes of low estrogen levels can be divided into four categories: natural causes, lifestyle factors, induced causes, and other causes.

Recall that estrogen fluctuates on a monthly basis within the menstrual cycle. However, low estrogen in women naturally occurs during childbirth and breastfeeding.
When a woman is pregnant, the placenta produces the majority of estrogen - estriol – starting around the ninth week of pregnancy until full term. After delivery of the placenta, estrogen levels drastically decrease within the following 24 to 48 hours.
In over half of women, these levels are so low that they resemble those of menopausal women. Depending on the woman, estrogen levels may remain low for several months after childbirth, especially if breastfeeding.
Breastfeeding poses a time when estrogen levels are usually low due to the causal relationship between prolactin levels and the absence of ovarian activity. Blood levels of prolactin will remain high, and in this way, suppressed estrogen levels can act as a form of birth control for many women.
During these times, low estrogen symptoms may ensue because endocrine and reproductive system health is affected. Symptoms include migraines, irritability, decreased libido, and more.
As eggs are expended throughout the years, there is a corresponding decline in the secretion of estrogen. This continues until menstruation ceases, and postmenopause begins.
This decline in estrogen levels is predominantly what causes the host of symptoms women experience, including night sweats, vaginal dryness, mental fogginess, hot flashes, and more.
For a needed hormonal boost, postmenopausal women may choose to pursue HRT (with risks involved) or supplement with estrogen products (pills, creams, patches, and gels). Natural treatments in the form of herbal supplements that nourish hormonal glands are also viable options.
Also, there are a variety of lifestyle factors that can cause low estrogen levels. Some of them include, but are not limited to, the following:
Diet. Fatty foods have a very strong influence on hormonal activity in the body. It has been found that with high-fat diets, estrogen levels increase. However, the opposite is also true; low-fat diets will cause estrogen levels to drop significantly in a short amount of time.
Stress. Excessive stress can disrupt hypothalamic function, which stimulates and regulates endocrine activities, causing an estrogen deficiency. Moreover, research has proven that days with higher perceived levels of stress are characterized by lower levels of estradiol in women's saliva.
Eating disorders. Eating disorders, such as anorexia nervosa, and extreme dieting can lead to estrogen deficiency. Low female body weight can prompt the body to stop producing estrogen, resulting in amenorrhea - a lack of menstruation - and further medical concerns.
Extreme exercise. Stress- and exercise-induced amenorrhea from insufficient body fat content causes the body to believe it is in a “starvation state.” This shuts down bodily operations not deemed necessary for survival, such as those of the reproductive system.
Various procedures and treatments can cause lower estrogen levels, including hysterectomies, radiation therapies, and certain medications.
Hysterectomies involve the surgical removal of reproductive organs. Women who have their ovaries removed - as part of a total hysterectomy, or “surgical menopause” - can suffer from decreased estrogen levels as the procedure halts ovarian hormone production.
Following a partial hysterectomy in which just the uterus is removed can also force a woman to enter surgically-induced menopause. Typically, the ovaries stop working within one to three years afterwards as blood flow to them ceases.
Also, loss of ovarian function from chemotherapy or radiation therapy can be permanent or temporary. Functions may stop as soon as two to three weeks into treatment. It depends upon the type of chemotherapy received and whether or not radiation was utilized on the ovaries.
Moreover, use of exogenous hormones and medications for other medical conditions can also trigger low estrogen levels. Drugs such as rifampicin, barbiturates, warfarin, primidone, and more decrease estrogen levels by enhancing the hormone's metabolism in the liver.
Moreover, the following conditions can each prompt low levels of estrogen in women:
Overall, there are a range of natural, induced, and other causes that can provoke low estrogen levels throughout a woman's reproductive life.
