A team of endocrinologists from Garvan Institute of Medical Research has asserted that obese patients undergoing gastric surgery to lose their weight, as they fail to bring down their weight by other means, are at high risk of long-term bone loss.
These gastric bypass procedures (GBP) include the operations, which divide the stomach into two portions, a small upper pouch and a large lower pouch, both of which are connected to intestine. The procedure reduces the functional volume of stomach and also alters the physiological and physical response to food.
Endocrinologists asserted that the procedure can also decrease the density of bone. The issue has raised major concerns as many teenagers also undergo the surgery and their bone mass is yet to reach the highest level.
Dr. Malgorzata Brzozowska from the university thoroughly studied a recent research based on the relationship between fat, bone and dietary restrictions.
She said, "The more invasive types of surgery appear to heighten bone turnover and the associated bone loss. This is caused by rapid weight loss and absorption of fewer vital nutrients".
Further, she asserted that there are chances that even modification in hormones released by fat and alimentary canal and the influence laid by them on central nervous system would play a role in bone loss.
