What do I do if my T4 is low?
The easiest and most effective treatment is simply taking a thyroid hormone pill (levothyroxine) once a day, preferably in the morning. This medication is a pure synthetic form of T4 which is made in a laboratory to be an exact replacement for the T4 that the human thyroid gland normally secretes.
How can I raise my T4 levels?
Several health studies have shown that T3 and T4 hormone levels increase with exercise. Beyond helping to stimulate thyroid production, exercise also helps to counteract many of the side effects of hypothyroidism such as gaining weight, loss of muscle, depression, and low energy levels.
Does low T4 cause weight gain?

What do high and low TSH levels mean?

What does low T4 thyroid mean?
Lower-than-normal T4 levels usually mean you have hypothyroidism. However, some people may have increased TSH levels while having normal T4 levels. This is called subclinical (mild) hypothyroidism. It is believed to be an early stage of hypothyroidism.
What causes a low TSH level with a normal free T4 level?
Subclinical hyperthyroidism causes a low thyroid stimulating hormone level and a normal free thyroxine, or T4, level, according to WebMD. The cause of subclinical hyperthyroidism may be endogenous due to the overproduction of thyroid hormones, or exogenous due to the administration of thyroid hormones, explains American Family Physician.
