Thyroid ( TSH, Free T4 and FT3)
TSH, Free T4 and FT3 (free T3) are measured in this test (even if your TSH is good).
You are tired... Ideally, you would like to lie in bed and sleep. Your body feels stiff and rigid and moving hurts. Your mood is depressed or changes rapidly. you feel rushed and sleep poorly.
Most disorders of the thyroid gland result in too little or too much thyroid hormone being made. This leads to many physical symptoms. With an overactive thyroid, these include: a fast heartbeat, weight loss, nervousness, trembling hands, irritated eyes, sleeping problems and a hunted feeling. In women, an irregular menstrual cycle may also occur. With thyroid hormone deficiency, the patient suffers from weight gain, dry skin, constipation, feeling cold easily, fatigue and in women heavy menstrual bleeding.
is made in the pituitary gland, an important hormone-producing gland in the brain. TSH ensures that the right amount of thyroid hormone (T4 and T3) is always produced. Thyroid hormone regulates the use of energy in the body it has a kind of thermostat function.
(FT4, free T4, free thyroxine) is a thyroid hormone. This hormone ensures that all kinds of processes in the body run fast enough. A value that is too low indicates a thyroid that works too slowly. Too high a value of FT4 indicates a thyroid gland that works too fast.
Is the hormone that arises from T4 and causes the final effect of thyroid hormone. So actually FT3 is more important than T4, but we measure T4 to examine changes in thyroid function.
