Patient discussion about excitability

Q. I am excited to know in what way diet helps in preventing osteoporosis? my mother is suspecting to be having osteoporosis. She regularly complains of leg pain. Upon consultation with the doctor it was found with low calcium in her blood. She was given calcium tablets and was told to increase in the diet rich in calcium. She is taking milk and yoghurt especially. She is not well yet but shows some improvement. I am excited to know in what way diet helps in preventing osteoporosis?

A. you see, our bones are a giant storage of calcium. our body needs a very steady concentration of calcium, if it'll be low the body will take it form your bones. if there's too much- it'll either build bones (but only if he'll think he needs too- that is where sport get in the picture)or you'll urinate it.any way, you rather have large amount of calcium in your diet then less. but it's not enough- sport and other medication can help.
