Last night, I went to dinner with a group of friends and two of the men disclosed that they were recently diagnosed with low testosterone and were prescribed testosterone treatments by their doctors. One was in his early 60s, the other in his early 40s. While it’s common for the testosterone level in men to decrease little by little as they age, turns out, some men experience a sharper, steeper drop in this hormone similar to when a woman goes through perimenopause and menopause (in men, it’s called “andropause”). I bring this up because if you know a man with symptoms of low testosterone—which include fatigue, depression, weight gain, anxiety, memory loss and/or loss of sex drive—you may want to suggest he get his testosterone checked. Both of my friends experienced dramatic results from their treatments. To learn more about low testosterone, visit WebMD.com.
