When the levels of estrogen, the primary female sex hormone are increased reative to the levels of progesterone circulating in the blood, women are said to be experiencing estrogen dominance.

The most common symptoms and signs of estrogen dominance include:

  • Decreased sex drive
  • Increased PMS symptoms
  • Irregular periods
  • Depression
  • Mood swings
  • Headaches
  • Bloating
  • Hot flashes
  • Breast tenderness
  • Weight gain
  • Fatigue
  • Difficulty concentrating
  • Insomnia

Let’s take a closer look at the symptoms of high estrogen and whether it might be time to test your estrogen levels.

Symptoms and signs of Estrogen Dominance

Symptoms of high estrogen levels vary from person to person and depend largely on the severity of your hormone imbalance.

Remember, while these are all symptoms of a fluctuation in estrogen levels, they may also signal other health problems.

Decreased sex drive

While optimal levels of estrogen stimulate vaginal lubrication and increased sexual desire; higher estrogen levels may cause mood swings, worsened PMS symptoms and fatigue - each of which naturally have an effect on your sex drive.

Increased PMS

High levels of estrogen may leave women feeling that their PMS symptoms have increased in severity - severe bloating, feeling especially emotional and bad back pain in the days leading up to your period may be a result of significant fluctuations in estrogen.

Irregular periods

Women experiencing a fluctuation in estrogen levels are more likely to experience irregular periods. Mayo Clinic suggests that a significant change in your period may suggest that your hormone levels have shifted [3].

Depression/ Mood swings

For those living with increased levels of estrogen, you may experience extreme emotions. This can happen in the lead up to and/or the aftermath of your period.

Difficulty concentrating

Headaches and difficulty concentrating have been linked to estrogen when it exists in the body in either too high or too low a volume. It’s been found that more than half of women who experience migraines believe it to be linked to their menstrual cycle [4].


Bloating is usually caused by water retention or disruption in the water-salt balance in females. An increase in estrogen levels and fluctuation of your hormones may cause water retention, which can cause bloating [5] .

Hot flashes

Hot flashes are one of the trademark symptoms of menopause. They can indicate increasing estrogen levels if you’re experiencing them well before your periods are expected to come to an end [6].

Tenderness in the breasts

During the menstrual cycle, tenderness in the breasts can often be attributed to the decreased volume of progesterone in relation to estrogen - this is generally a natural occurrence. With that said, recurring sensitivity in the breasts may also be attributed to higher levels of estrogen.

Weight gain

A tell-tale sign that you may be having issues with your estrogen levels is weight gain - particularly around your middle.

This weight gain is most likely to take place during menopause which may be confusing for people to hear due to the fact that both estrogen and progesterone are believed to drop during this period. What is often misunderstood is that progesterone drops more dramatically than estrogen which gradually leads to weight gain.


Low progesterone, in comparison to levels of estrogen is said to lead to feelings of fatigue [7].


It’s unsurprising that some of the above symptoms would keep you up at night. Though, another reason that you may be struggling to fall asleep is the fact estrogen and progesterone are sleep promoting hormones and fluctuations may lead to sleep disruptions.

How to know if you have Estrogen Dominance

It’s recommended that you test your estrogen levels if you’re experiencing signs of fluctuating hormone levels or if you’re simply hoping for a greater understanding of your hormone levels.

If you’d rather not make the visit to your local doctor, the best way to test your estrogen levels is with an at-home lab test.
