In general, both men and women tend to gain weight as they age. In men, the hormone testosterone helps sustain muscle tissue. So around age 50 when a decrease in testosterone becomes apparent, men often start losing weight because they are losing muscle mass.
For women, the tendency to gain weight continues for another 15 or more years. Women typically don’t start losing weight due to loss of muscle mass until about age 65.
Men and women also have different risks of mental impairment as they age. In general, a man’s risk of cognitive impairment increases if he is overweight, has diabetes or has had a stroke. A woman’s risk decreases if she is able to live independently without having to rely on others for daily help, and if she has a strong social network.

While women are more likely to develop heart disease, men are five times more likely to experience an aortic aneurysm, which is a weak spot or bulge in wall of the major blood vessel leaving the heart. Men are also more likely to die from a heart attack at an earlier age than women.
