Yes, they can be linked. A
TSH of 37.6 means your
thyroid is very underactive. That can affect the inner ear and nerves, adding to dizziness and poor balance. An underactive thyroid also commonly causes anaemia. Low haemoglobin also makes you lightheaded. So all three problems may share one root. Treating the thyroid usually improves energy, haemoglobin and dizziness over a few weeks to months. True spinning can also come from the inner ear itself, so it still deserves its own check.
Next Steps
Please see a physician or endocrinologist this week to start
thyroid treatment. Ask about a free T4, a repeat haemoglobin and an iron profile.
Health Tips
Get up slowly from bed or a chair. Avoid driving or climbing heights while the spinning continues.
