I am a Male, 24, 75 kg.
Whenever I am outside I get hot and sweaty. I am not out of breath easily because I go to the gym. I'm just HOT. This has been an issue since I was a child. I never wore jackets in the winter. I am most comfortable around 16-18°C. Everything above 21°C is really uncomfortably hot for me. My metabolism seems to be slow. I was always skinny and barely had any appetite. I feel weak and tired most of the time. Also, I've been suffering from depression for the past three years. But it is not the cause of the sweating. I keep thinking: maybe what causes the sweating (out of balance hormones) also causes the depression?
Recent thyroid blood test shows:
FT3: 3.5pg/ml (normal 2.0-4.2)
FT4 1.2ng/dl (normal 0.8-1.7)
TSH 3.18mlU/l (normal 0.35-4.50)
TPO < 1.0 (normal < 5.6) (Thyroperoxidase Antibodies)
So it seems like my thyroid is actually slower than usual which should make me cold, right? Either way, I have started taking L-Thyroxin 25mg to lower the TSH.
I don't get it. I'm grateful for any kind of advice of what to do next.
