Subclinical Hypothyroidism and Treatment Options.
I'm here to discuss recent thyroid lab results that show subclinical hypothyroidism. I am also experiencing significant symptoms that are impacting my daily life, and I would like to discuss the possibility of treatment.
My primary symptoms are:
*I feel consistently tired despite adequate sleep.
*I have noticeable difficulty with concentration and memory.
*Muscle Aches: I experience persistent, unexplained muscle soreness.
Lab Result Summary (The Evidence)
My test results from August 18, 2025, are as follows:
*TSH: 5.64 mIU/L (High)
*T3: 3.35 nmol/L (High)
*T4: 130.37 nmol/L (Normal)

I’d also like to hear more about what has been effective for subclinical hypothyroidism. I’m 71, never had high TSH before. Recent TPO test, for autoimmune, was negative. In April TSH was 6, normal T3 & T4. In July TSH was 4, normal T3, T4. Next test will be end of this month. Endocrinologist thinks I will have chronic hypothyroidism and was ready to treat with Levothyroxine this summer. I’m not ready to get on the Levothyroxine rollercoaster (constant testing, dose adjustment).
I don’t feel fatigued, but I do drink a cup of coffee in am to get going, and maybe another before heading to the gym. Sleep is fine. I do have some memory issues but most likely caused by tamoxifen and age related.
I’m afraid if I “try” Levothyroxine there is no stopping it. Anyone have experience with starting Levothyroxine and finding it wasn’t needed, or caused too low TSH, and was discontinued?

2 ReactionsMy TSH has always run a bit high-latest is 6.2, with T3 & T4 in normal range. But lately I can't get warm, chill easily,hands like ice, depressed. My fingers and toes get tingly and numb.
I have an appointment with an endocrinologist later this month, and I'd be happy to start on levothyroxine if he thinks it will help. I know it can be difficult to get the right dose, but I'd try it.

2 Reactions@triciaot I’m on Synthroid 75 mcg and don’t feel any side effects from it. If you’re experiencing fatigue and brain fog. If you’re hypothyroid, you will need medication for your Thyroid as it sounds like you’re missing some hormones that your Thyroid produces. The medication will help that. If you don’t get on medication now, chances for getting Hashimoto’s are great. I unfortunately, have both Hashimoto’s and Hypothyroidism. To combat the Hashimoto’s, I have eliminated eating gluten, dairy and soy products to keep the body inflammation down. This works. You don’t want Hashimoto’s!

2 ReactionsWe here at Mayo Clinic Connect don’t diagnose or prescribe. We share our stories to be supportive and encouraging. Members here are doing that. My experience with thyroid is having hyperthyroidism/ Graves’ disease. My endocrinologist diagnosed and treated it. She cautioned me that I may eventually flip to hypothyroidism. She will help me deal with if / when it happens. She continues to closely monitor me.
My husband had thyroid cancer and it was surgically removed. He is on Levothyroxine now. The dose did need to be adjusted from time to time at first but has settled down. It has been 17 years now. His Dr. still monitors the level and will make adjustments in the dose if needed.
I had similar problems as you did. Chronic fatigue was consistent with me. I had thyroid problems for years but only needed a daily pill.
Talking to one of my other doctors he suggested to have my Endocrinologist test me for Addison's disease, which is a adrenal gland imbalance. It is only a blood test taken in 1 day with 3 blood samples. I took the test and it proved I do have Addison's. I have been on the meds for Addison's a few weeks now and feel better. I also had to increase my dosage for my thyroid.
Look up the symptoms for Addison's and if you have a bunch of these, consult with a Endocrinologist.
