What are the complications associated with hypothyroidism?

Hi,

Welcome to icliniq.com.

I can understand your concern.

So your thyroid profile shows very high TSH (thyroid stimulating hormone) (19.3 μIU/mL), normal T3 (thyroxine), and a T4 (triiodothyronine) of 12 ng/dL, which is actually within the lab’s normal range (4.3–12.5 ng/dL), so it is not high; it is just at the upper end of normal.

In hypothyroidism, especially autoimmune (like yours, anti-TPO antibodies are high, suggesting Hashimoto’s thyroiditis), the key marker your doctor is targeting is the TSH, not just the T4. Because your high TSH means your body is still not getting enough thyroid hormone, your pituitary is working harder to stimulate your thyroid, which is why TSH is high.

So increasing levothyroxine from 25 mcg to 50 mcg is a common and safe adjustment, and it would not cause your T4 to double overnight because the medication works slowly, and recheck your thyroid profile in six to eight weeks to fine-tune the dose.

As your vitamin B12 and vitamin D are also very low, these deficiencies are contributing to your hair fall and fatigue, so supplementation for them is also important alongside thyroid management. Always feel free to reach out at any time. I am always here to help regarding your hypothyroidism and vitamin deficiency levels.

I hope this information will help you.

Thank you.
