Dr Zubaida Rahman, Vice-President of Ziaur Rahman Foundation and spouse of Prime Minister Tarique Rahman, yesterday called for implementation of a coordinated programme across the country to ensure treatment for those suffering from osteoporosis and to raise public awareness about the disease.Describing the osteoporosis as a 'silent' disease, she said it causes bones to become weak, thin, and porous, significantly increasing the risk of sudden fractures. This condition disrupts the normal life of those affected and diminishes their ability to perform daily activities, she said.
