You’re going to get a lot of bad advice on this sub. But yes, retesting in a month or two is good medical advice before starting a life long medication that may or may not help with your symptoms. Hypothyroid symptoms look like a lot of other disorders. Don’t go doctor shopping because your first one didn’t push pills on you after one borderline TSH test. More on reddit.com

Subclinical hypothyroidism is a difficult topic because is has two categories of symptoms that can occur: Symptoms that can be easily and precisely measured (female infertility, miscarriage, deterioration of cholesterol) and symptoms that are non-specific and not easily measured (anhedonia, fatigue, depression, hair loss, anxiety). Infertility and miscarriages are easily measured and as a consequence most women will get treated if their TSH is above 2.5, certainly if it's above 5. On the other hand, fatigue, depression and anxiety are common, very non-specific and hard to measure objectively. What's more, levothyroxine tends to have a narrow therapeutic index (in most patients, not in all) and if you overdose the patient by a few mcgs she may be just as or even more anxious and fatigued (while mild overdoses on the other hand do not increase the risk of miscarriage, infertility or bad cholesterol), and patient A will do fine at a TSH level that may be too high for patient B but too low for patient C. This makes for very messy and contradictory clinical research and vague guidelines (much less so on the matter of pregnant women, of course). As a consequence, the same doctor who aggressively treats a woman for a TSH of 2.6 if she wants to get pregnant may scoff at the idea of treating someone with a TSH of 8 despite the latter's complaints that she can barely get out of bed and that half her eyebrows have fallen out. From the patients' perspective, this is very unsatisfactory and makes no sense. There's no reason to assume that hard-to-measure symptoms only occur at much higher TSH levels than easy-to-measure symptoms. More practically, many endos take an unexplained elevation of LDL cholesterol and the elevation of TPO/TG antibodies as an argument for treatment, as both make it much more likely that high-in-range or mildly elevated TSH indicates actual thyroid dysfunction. On a side note, the symptoms of iron deficiency (with or without anemia) broadly overlap with the symptoms of thyroid dysfunction, and according to newer studies, iron deficiency affects approximately 20-40% of the pre-menopausal female population, so it may be useful to give a patient complaining of non-specific symptoms iron for a few months unless their ferritin is actually high.

I'm subclinical but symptomatic and have been taking Levo for almost a year. I managed to lose weight, even if very slow, the brain fog is much better as is the tiredness. My hair has grown a lot, which it hadn't in a long time. Mood swings have gone down considerably. I feel overall much more like myself again. Edit Sorry, just reread and you wanted unusual symptoms... I used to get ice cold hands and feet, which is unusual because I don't get easily cold. It got so far I bought rechargeable heated gloves. Last winter was the first one in years without those cold spells. I also get extremely itchy skin between my fingers. This symptom has gone down considerably. Same with itchy scalp.

I’m here from the perspective of someone trying to conceive, my periods are irregular and when I did have a positive pregnancy test it ended very quickly in an early miscarriage. When my TSH was 5.23, my T4 was slightly below normal ranges; but because of opinions shared in videos and articles like these about TSH must be >10 for treatment, I’ve never been able to access medication. These studies mostly focus on the treatment of older age groups, and it’s worth noticing that some like the BMJ specifically say that pregnant people or people TTC are excluded from the recommendations not to treat SCH. If something can have a big enough impact on your health to affect menstrual cycles or fertility - why is it so hard to believe it might also be impacting other areas of my health? More on reddit.com
