My name is Ricardo I am a 22 year old male and I have had a strong suspicion that I have hypothyroidism. There are days where I suffer from brain fog, I sometimes get fatigued, my extremities are cold, I have a hard time doing exercises and losing any weight on my belly. My skin has been dry ever since I was a teen, my hair comes out in clumps not just from the top but also from the sides, I also have enlarged eyes and my fingernails do not have any moons except for my thumbs ( I hear that if you do not have moons up to your ring finger your thyroid is low). Anyhow, I got tested a year ago by a doctor, however, she only tested my TSH which was 7. She told me she wasn't too worried as if it was true hypothyroidism my TSH would be upwards of 10 or so. After this I went online and researched my butt off. I learned that the cut off for TSH levels are not 0.5 - 5 as she was mentioning but that they have been changed to 0.5 - 2.5 or so. She did say that I had subclinical hypothyroidism and that medication is not necessary so far, she also told me that she had a suspicion that I might have Hashimotos and that I would eventually need medication my entire life. Fast forward to today and I recently did a full panel thyroid test as I have been having more symptoms this year and they vary from day to day. I just received the results and I have to say that I am very confused and was hoping that someone one here can help me explain what is going on? I will post both my test results and lab comments. The lab comments doesn't tell me exactly what I should do, which is why I am asking for your opinion.
Free T4: 1.6
Free T3: 4.2
Lab comments from the lab test:
Free T4 is within normal range but reported symptoms indicate thyroid deficiency. This might suggest that hepatic conversion of T4 to T3 is impaired or T4 is being converted to reverse T3 (both conditions increased under conditions of high stress/cortisol). It would be worthwhile to evaluate steroid hormones by saliva and correct any hormonal imbalances (eg. high estradiol, low progesterone, low testosterone, high or low cortisol) that might impede optimal thyroid function.
Free T3 is within normal range but symptoms indicate thyroid deficiency. A normal T3 does not exclude the possibility of a "functional" thyroid deficiency caused by other hormonal imbalances such as excess estrogen, low progesterone, low testosterone, low or high cortisol, and low growth hormone (IGF-1). Testing for these hormones is recommended.
TSH is high. Although most laboratories have a TSH range of 0.35-5.50, new studies are finding that the mean and median values are 1.0-1.5mU/l . TSH levels >3.0 are now considered abnormal due to changes by the endocrinology association - see aace.com for more information. Some experts believe that TSH should be kept below 2.0 for optimal health. Elevated TSH is often associated with symptoms of hypothyrodism, which include fatigue, decreased stamina, depression, rheumatic pain, sleep disturbances, cold extremities or feeling cold, reduced body temperature, brittle nails, dry coarse hair, hair loss, infertility, low libido, puffy eyes and face, decreased sweating, menorrhagia, and/or constipation. Periodic TSH monitoring is recommended if clinical symptoms of thyroid deficiency persist. Thyroid therapy may be worthwhile considering if T4 and/or T3 are low and symptoms of thyroid deficiency are problematic.
Thyroid peroxidase (TPO) antibodies are low indicating that Hashimoto's autoimmune thyroiditis is unlikely.
