Some initial signs of osteoporosis to look out for include: - Back pain - Loss of height - Bad posture - Weak and brittle fingernails - Reduced gums - Bone loss in the jaw - Decreased grip strength - Fractures The listed symptoms can also be a sign of other illnesses, so an osteoporosis doctor should be consulted for a precise diagnosis. Early diagnosis and treatment of osteoporosis can also lessen the risk of fractures and help stop further bone loss.
