Hormones and Dizziness: What’s the Connection?

By Lisa Brekke, PT, DPT

Dizziness is one of those symptoms that can feel vague, unsettling, and frustrating to pin down. While balance issues can stem from the inner ear, blood pressure, medications, or even stress, one often-overlooked factor is hormones.

Hormones play a major role in regulating blood flow, fluid balance, and even how our brain and nervous system process signals. When these levels fluctuate, it can sometimes leave us feeling lightheaded, off-balance, or “swimmy.” Let’s look at a few common ways hormones and dizziness intersect.

Another important note to link hormones and dizziness is that estrogen receptors are found in the inner ear; both in the cochlea and semicircular canals.

1. Menstrual Cycle and Estrogen Fluctuations

Many people notice dizziness at certain points in their cycle, often just before or during their period. Estrogen levels dip, which can:

• Influence fluid regulation in the inner ear.

• Make migraine attacks (including vestibular migraines) more likely.

• Contribute to changes in blood pressure and circulation.

2. Pregnancy

Pregnancy brings dramatic shifts in hormones like estrogen and progesterone. These changes can:

• Lower blood pressure, leading to lightheadedness.

• Affect blood sugar stability.

• Influence vestibular sensitivity, making some women feel dizzier than usual.

3. Perimenopause and Menopause

As estrogen and progesterone naturally decline, many women experience new or worsening dizziness. These fluctuations can also worsen migraines or contribute to hot flashes, night sweats, and sleep changes, all of which can indirectly affect balance.

Current research indicates that both vestibular migraine attacks and benign paroxysmal positional vertigo (BPPV) increase in frequency during perimenopause.

4. Thyroid Hormones

Both underactive (hypothyroidism) and overactive (hyperthyroidism) thyroid conditions can cause dizziness. This may come from changes in metabolism, blood pressure, or heart rhythm.

5. Cortisol and Stress Hormones

When stress hormones like cortisol and adrenaline spike, they can:

• Raise heart rate and blood pressure.

• Cause sensations of lightheadedness or “head rushes.”

• Contribute to feelings of unsteadiness during anxious moments.

What You Can Do

If you suspect your dizziness may be linked to hormones, here are a few steps to consider:

• Track your symptoms: Note when dizziness occurs and see if it follows a cycle or certain trigger.

• Talk to your provider: Blood work or hormone testing may be helpful.

• Lifestyle support: Hydration, balanced nutrition, and stress management can help reduce swings.

• Specialized care: Vestibular physical therapy, migraine management, or endocrinology support may be recommended depending on the cause.

Bottom Line

Hormones and dizziness are deeply connected. If you find your symptoms fluctuate with your cycle, pregnancy, menopause, or thyroid changes, you’re not alone and there are effective strategies to help. The key is recognizing the pattern and seeking support tailored to your body’s needs.
