We all have days where we’re just not “in the mood.” But for younger men experiencing frequent lack of libido, low testosterone (low T) could be the culprit. Low T also significantly increases the chances of diabetes and heart disease in men.

Symptoms
From fatigue and low sex drive to hair loss and decreased bone mass, “symptoms of low T overlap with other health issues, and it is often confused with signs of natural aging,” says SIU urologist Dr. Köhler. “For example, a man who has trouble getting erections might be less interested in sex and more depressed than usual. Depression, anemia, sleep issues and other things could also be causing the symptoms.”

The overall message
Every man with a symptom of low T doesn’t need to have testosterone a supplement. “The main point of increasing testosterone is to give a man more energy and increase sex drive so he can go exercise and take better care of himself,” Dr. Köhler says. Testosterone changes the body from a catabolic state to an anabolic state so that it burns fat instead of storing it, thus aiding weight loss.

If you think you might be suffering from low T, talk to your primary care physician or urologist.
