Researchers have warned about reduction in bone density for those who undergo gastric surgery to lose weight.
Obese patients resort to gastric surgery after all effort to reduce weight has not yielded results.
Gastric surgery restricts the amount of food a person can eat and this may cause nutritional deficits and result in reduced bone density. Teenagers who undergo this surgery need to be extra cautious in this regard.
Dr Malgorzata Brzozowska from Sydney's Garvan Institute of Medical Research, said, 'The more invasive types of surgery appear to heighten bone turnover and the associated bone loss. This is thought to be caused not only by rapid weight loss and absorption of fewer vital nutrients like vitamin D and calcium, but possibly also by changes in hormones released by fat and the gut, and their impact on the central nervous system.'
