Hi guys, So I'm in a bit of a pickle today about 3 months ago I had my testosterone, fsh and lh tested and all of them came back low. The doctor referred me to an endo but the appointment is in 4 months. I had long suspected my oestradial levels may be high also so had it tested privately not wanting to wait any longer for help with my problems and it came back normal. This has left me puzzled since I have alot of symptoms of high estrogen but fair enough. Anyway so onwards with my questions.... How do low hormones (specifically low testosterone) cause fatigue??? what is the mechanism??? I'm so if the above question is a bit vague but I hope you understand I'm asking how can low testosterone eventually lead to chronic fatigue or just long-term fatigue which is what I have. My second question: How can I overcome fatigue caused by low testosterone without going on TRT??? Which supplements can I take??? The reason I ask is because I'm not sure my doctor will give me TRT and I'm almost 100% certain now (after doing some private and NHS blood tests) that my fatigue is due to low testosterone. thanks for replies and sorry for the long-winded post.
