A
TSH of 4.830 mIU/L is at the upper end or slightly above the normal reference range (most labs use 0.5â4.0 or 0.5â4.5 as the upper limit). This pattern â TSH slightly elevated with no other obvious symptoms â is called subclinical hypothyroidism. Hair loss is a well-recognised early symptom of an underactive
thyroid, and it can appear even when the TSH is only mildly elevated. The TSH alone is not enough to make a decision â you need to check Free T3 and Free T4 along with anti-TPO antibodies (to rule out Hashimoto's thyroiditis, an autoimmune thyroid condition that is very common in this age group and often starts exactly like this).
Next Steps
Get Free T3, Free T4, Anti-TPO antibodies,
Vitamin B12, iron studies, and
Vitamin D levels done â all of these can contribute to hair loss. Repeat
TSH in 2-3 months if you don't start treatment. Based on the full panel results, a physician will decide whether
thyroid medication is needed. Please consult me directly on Practo for a detailed evaluation.
