I have a loss of energy and sex drive. ?

Low energy and sex d: This could be low testosterone or hypothyroidism, or other things. I would see a doctor and see if they want to do some blood tests on you.

?Low T: Decreased libido and energy are not uncommon as a man ages, however, there may be medical causes such as medication side effects, thyroid disease, decreased testosterone levels, depression, etc. You would be best served to see a dr., have a "check-up" and get some routine testing done, including lab work. Best wishes.
