Generally, we need to see the test sheet. For example, TSH is generally 5 to 10 or more, 5 to 10 is relatively light in clinical practice, and 10 or more is relatively heavy. The normal values of T3 and T4 are different in each hospital. It mainly depends on the comparison between the values in the hospital and the normal values. A lower value is clinical hypothyroidism. The mild hypothyroidism is called subclinical hypothyroidism. Subclinical hypothyroidism means that T3 and T4 are still in the normal range, but TSH is high. If it is slightly elevated, if it is 5 to 10, it is considered to be relatively light. If it exceeds 10, it is obviously elevated. If it gets worse, it will become clinical hypothyroidism. In addition to the increase of TSH (thyroid stimulating hormone), the decrease of T3 and T4 will lead to obvious hypothyroidism. Treatment is required for hypothyroidism, especially clinical hypothyroidism or severe subclinical hypothyroidism.
