A
TSH of 37.6 is markedly high, so your
thyroid is working well below normal right now. An underactive thyroid like this very often brings on dizziness, poor balance and anaemia together, so your symptoms are likely connected rather than three separate issues. True spinning vertigo can also come from the inner ear, so that still deserves its own check.
Next Steps
Please see a physician or endocrinologist this week to start
thyroid treatment, and get a repeat haemoglobin and iron profile done alongside it. Dizziness and tiredness usually ease over a few weeks once your thyroid level comes down.
Health Tips
Get up slowly from sitting or lying down, and avoid driving or climbing heights until the spinning settles.
