What is thyroid vertigo?

Yes, thyroid issues, both underactive (hypothyroidism) and overactive (hyperthyroidism), can cause dizziness by affecting the inner ear (vestibular system) and cardiovascular function, leading to balance problems, vertigo (BPPV), or heart rate changes, with hypothyroidism often linked to Meniere's disease and hyperthyroidism to palpitations and rapid heart rate. Treating the underlying thyroid disorder often resolves these dizzy spells, highlighting the importance of checking thyroid health for unexplained vertigo, says the NIH and this National Institutes of Health article.

What is the root cause of thyroid issues?

The root causes of thyroid issues are multifactorial, primarily stemming from autoimmunity (like Hashimoto's/Graves'), driven by genetics, stress, inflammation, and environmental triggers (smoking, toxins, infections). Iodine imbalance (deficiency or excess), nutrient deficiencies (selenium, zinc), and factors like pregnancy, radiation, certain medications, and gut health also play significant roles, leading to underactive (hypo) or overactive (hyper) thyroid function. 

Can you survive without a thyroid and no medication?

No, you cannot survive long-term without a thyroid and no medication; your body needs thyroid hormones to regulate metabolism, growth, and energy, so removing the gland requires lifelong daily hormone replacement (like levothyroxine) to prevent severe, potentially fatal complications like myxedema coma. While you can live without a thyroid, you cannot live without the hormones it produces, making medication essential for maintaining health and normal function.
