Too Much Anxiety and Worry Can Be Caused By Hormone Imbalance

Yes, a hormone imbalance can cause anxiety. In women in their 40s and 50s it is a common cause of new anxiety with no clear trigger.

More than one hormone can cause anxiety. Each leaves a different pattern of other symptoms.

Six things worth knowing.

In perimenopause, estrogen can spike and fall within a single cycle, and many women feel the drops as sudden dread, often years before hot flashes.
Progesterone is the calming half of the pair. Anxiety that reliably arrives before a period, then lifts, is the classic progesterone pattern.
Cortisol that stays high from ongoing stress can leave you wired but tired, waking in the night, with cravings and weight around the middle.
An overactive thyroid most closely imitates an anxiety disorder. Thyroid is easy to test for and should be checked whenever anxiety is new.
It can be both. Hormonal anxiety tends to have a pattern; an anxiety disorder tends to be more constant and present for years.
What helps, in order of evidence: sleep and regular meals, treating the anxiety itself, testing thyroid, and hormone therapy when anxiety follows hormone changes.

Estrogen and anxiety

Estrogen influences serotonin, GABA and the stress response, so changes in estrogen can affect anxiety.

In perimenopause, estrogen can spike and fall within a single cycle. Many women feel the drops as sudden dread, a racing mind, or a sense that something is wrong. This can begin years before hot flashes and is often missed. Women with a history of PMS, PMDD or postpartum mood changes are more likely to notice it.

Too much estrogen can cause anxiety too. That includes a hormone therapy dose that is higher than you need.

Our guide to estrogen overload and anxiety covers it in detail.

Progesterone and anxiety

Progesterone has a calming effect, so anxiety can rise when it falls.

One of its breakdown products acts on the same GABA receptors as anti-anxiety medications. That is why many women feel calmer and sleep better in the days after ovulation. Progesterone falls in the week before a period, and more erratically in perimenopause. Anxiety that reliably arrives before a period, then lifts, is the classic progesterone pattern.

This is illustrative, not a chart of your cycle.

Cortisol and anxiety

Cortisol is the body’s stress hormone. Short bursts are normal, but a level that stays high can keep you feeling on alert.

A baseline can stay high because of ongoing stress, pain, poor sleep or too little food.

The signs:

Wired but tiredWaking in the night, mind racingSugar and salt cravingsWeight around the middle

In perimenopause, falling estrogen makes the stress response more reactive, so cortisol and estrogen problems often arrive together.

Our guide to adrenal fatigue explains why we talk about stress load rather than a worn-out gland.

Thyroid and anxiety

An overactive thyroid is the hormone cause that most closely imitates an anxiety disorder.

Overactive (hyperthyroid)

Racing heart, sweating, tremor.
Insomnia, and weight loss despite eating.
A feeling of being revved up.

Underactive

More often causes low mood and fatigue.
Can include anxiety.

Both are common in midlife women, and both are easy to test for with TSH and free T4.

Testosterone, blood sugar and the amplifiers

Blood sugar swings, caffeine, alcohol and low testosterone can all make anxiety worse.

Low testosterone

Doesn't cause anxiety directly, but the fatigue and flatness that come with it make everything harder to cope with.

Blood sugar swings

A high-sugar breakfast or a long gap without food can produce shakiness and anxiety that is entirely physical.

Caffeine on an empty stomach

Several coffees on an empty stomach can produce the same shakiness and anxiety.

Alcohol

Alcohol can cause shakiness and anxiety the next day.

These are worth addressing first, because they can make every other cause worse.

Is my anxiety hormonal or an anxiety disorder?

It can be both, and treating only one may leave you only partly better.

Hormonal anxiety tends to…

Arrive in a cycle: before a period, at a dose change, or alongside hot flashes and night sweats.
Be new, in your 40s, in someone who was never anxious before.
Travel with physical symptoms: a racing heart, heat, sweating, 3 a.m. waking.
Improve when the physical symptoms are treated.

An anxiety disorder tends to…

Be more constant.
Be more tied to specific worries.
Have been present, even quietly, for years.

How to treat anxiety caused by hormones

Treat the cause and the symptom together, starting with what has the strongest evidence.

1
Protect sleep and keep meals, alcohol and caffeine steady.
Regular meals, less alcohol, caffeine before noon only, and treating night sweats. These can reduce the swings that hormone changes make worse.
2
Treat the anxiety itself.
Cognitive behavioral therapy has the strongest evidence for anxiety, and it also helps with how much hot flashes and poor sleep disrupt your life. See CBT for menopause. SSRIs and SNRIs are effective for anxiety and can reduce hot flashes; they are a reasonable choice when hormone therapy isn't.
3
Test what's testable.
Thyroid first. Hormone panels can help in perimenopause when the symptom pattern isn't clear, though a single estrogen reading is often misleading because the level changes day to day. Our guide to hormone tests explains when testing is useful.
4
Hormone therapy, when anxiety follows your hormone changes.
For women in perimenopause whose anxiety arrives with hot flashes, night sweats and poor sleep, hormone therapy can reduce the anxiety by steadying what is causing it. It is not a treatment for anxiety disorders on its own, and a dose that is too high can cause anxiety. Your prescriber will weigh it alongside the options above.
5
Supplements, with care.
Magnesium and L-theanine have modest evidence; most others sold for "hormonal anxiety" have little. They are optional. See supplements for perimenopause and menopause.

What women ask first.

Can a hormone imbalance cause anxiety?

Yes. Estrogen, progesterone, cortisol and thyroid hormones all act on the brain circuits that regulate fear and calm. When one of them is too high, too low, or changing quickly, anxiety is a common result, even in people who have never been anxious before.

What hormone causes anxiety?

There isn't one. The most common culprits in women are swinging estrogen and falling progesterone in perimenopause, high cortisol from chronic stress, and an overactive thyroid. Each has a different pattern of other symptoms.

What are the symptoms of hormonal anxiety?

Anxiety that arrives in a pattern: a week before your period, around a dose change, in the early hours of the morning, or alongside hot flashes, night sweats, palpitations or a racing heart. New anxiety with no history of it, in your 40s, can be a sign of perimenopause.

How do you treat anxiety caused by hormones?

Treat the cause and the symptom together. Steady the hormone swing where possible (sleep, blood sugar, and in perimenopause sometimes hormone therapy). Treat the anxiety itself with what has the strongest evidence: cognitive behavioral therapy and, when needed, an SSRI or SNRI. Supplements have modest evidence and are optional.

Does hormone replacement therapy help anxiety?

It can, when anxiety tracks with perimenopausal hormone swings or with hot flashes and poor sleep. It is not a treatment for anxiety disorders on its own, and a dose that is too high can itself cause anxiety. A prescriber will weigh it alongside non-hormonal options.

What supplements help with perimenopause anxiety?

Magnesium and L-theanine have modest evidence for anxiety; several others are sold for it with little evidence. None replaces fixing a hormone swing or treating an anxiety disorder. Our supplements guide lists what has evidence and what doesn't.
