From last 1 year I'm facing some slurring of speech in pronouncing words with 's'.Earlier I had never an issue and I had very clear diction. I'm afraid that it may be due to thyroid (hypothyroidism) issues which I have for some time. My latest thyroid report shows TSH - 8.1, T3 and T4 are in normal range. In my previous reports from last 4 years TSH has been in range of 5-6 .T3 and T4 in normal range though towards lower scale. 4 years before I was diagnosed with high blood pressure and since then I am on hypertension medication .I take Telma-h 40 mg and my BP is now in control. I also had moderately high cholesterol earlier and I also take LILO - 10 mg. My latest lipid profile is normal except HDL - 36 (range 40 - 60) which is slightly borderline. TSH has also been slightly higher since my diagnosis 4 years earlier but I have never taken its medication coz it was never very high and T3, T4 were normal. Can speech slurring be thyroid related issue and I should consult?
