My TSH levels are 5.5 yet my T3 T4 are normal and I don't have any symptoms. I am not overweight and have no dizziness or fatigue. Yet I am worried. Are those levels normal?

Dr. Rania Mousa General Medicine
Hypothyroidism is any state in which thyroid hormone production is below normal. Normally, the rate of thyroid hormone production is controlled by the brain at the pituitary. Hypothyroidism is a very common condition and the symptoms of hypothyroidism are often -subtle.some symptoms are:
-Fatigue
-Depression
-Modest weight gain
-Cold intolerance
-Excessive sleepiness
-Dry, coarse hair
-Constipation
-Dry skin
-Muscle cramps
-Increased cholesterol levels
-Decreased concentration
-Vague aches and pains
-Swelling of the legs
well the tsh level depends on every lab reference ,but it appears that your tsh level is slightly high,normal T3 and normal T4 ,NO symptoms ,good metabolism since you are not overweight ,then you might have subclinical hypothyroid(means hypothyroid that still don't show )no treatments are needed since t3 t4 are normal with no symptoms BUT
what to do next?
after 6 weeks from the first test you have done repeat the tests again ,TSH,free T4(better reliable than T4) if TSH still high with normal free T4 then check the antithyroid antibodies ,if it comes normal with still no symptoms NO WORRIES and retest every 6 months
