Question: what is the difference between hypothyroidism and subclinical hypothyroidism?
Answer: TSH triggers the thyroid, a butterfly-shaped gland at the front of the neck, to make the hormones T3 and T4. Subclinical hypothyroidism occurs when TSH levels are slightly elevated but T3 and T4 are normal. Subclinical hypothyroidism and full-blown hypothyroidism share the same causes.
