Owing to Dr Graham's passion for cycling, he has written a couple of very interesting articles about sports, health and osteoporosis.
There is strong evidence that years of cycling, when not combined with a weight-bearing sport, results in a very high risk of developing osteoporosis.
Osteoporosis becomes a problem when women either participate in non-weight-bearing sports alone (cycling) or when a reduced calorie intake causes irregular menses and oestrogen deficiency.
A lack of vitamin D can result in osteoporosis. Adequate sun exposure is necessary for the formation of Vit D.
