Signs and symptoms of high and low estrogen levels

There are natural changes in estrogen levels throughout our lifetimes and our menstrual cycles, but when they drop too low or rise too high, that can lead to health problems down the line. Read all about the hormone (and why it’s so important) below.

What is estrogen and why is it important?

Estrogens are a group of sex hormones in people with ovaries. They include estrone (E1), estradiol (E2), and estriol (E3), and they’re produced by the ovaries, the adrenal gland, and the placenta during pregnancy.

At puberty, estrogen leads to the growth of breasts, pubic and underarm hair, and kick off (and later help control) our menstrual cycles.

Estrogen also plays a role in keeping our cholesterol levels in check, maintaining our bone health, and producing hormones that affect our brains, hearts, and skin (among other parts of our bodies). (Source)

Estrogen is produced in the ovaries, the adrenal gland, and the placenta during pregnancy.

What are low estrogen symptoms?

First, let’s talk about causes. Women may have lower levels of estrogen when they’re postmenopausal, after an oophorectomy (surgical removal of the ovaries), or when they have a lower body-fat percentage.

If you have lower levels of estrogen, you might experience:

Infrequent or disrupted periods
Hot flashes and/or night sweats
Sleeping issues
Decreased sexual desire
Mood swings
Dry skin
Menstrual migraines

Estrogen can affect many parts of a woman’s body

What are high estrogen symptoms?

Women can have higher levels of estrogen (aka estrogen dominance) because of hormonal birth control or a higher body-fat percentage.

If you have higher levels of estrogen, you might experience:

Weight gain
Changes in your period
Worsening of premenstrual syndrome
Non-cancerous breast lumps
Uterus fibroids
Fatigue
Decreased sex drive
Anxiety or depression

How do normal estrogen levels change with age?

During the reproductive years, estrogen levels naturally fluctuate throughout the menstrual cycle — they’re highest toward the middle and lowest during your period.

At the onset of menopause, when periods come to a complete stop, estrogen levels drop.
