Disease/Condition Glossary

Osteoporosis: It is a bone disease that weakens and brittle bones by decreasing bone density. As the density of bones decreases, they weaken and are more likely to break. Breaking a bone is a severe complication of osteoporosis, especially in older patients. Women are much more likely to develop osteoporosis than men. Signs and symptoms include back pain caused by a fractured or collapsed vertebra, loss of height over time, a stooped posture, a bone that breaks much more easily than expected.

Tetany: A disease condition due to low levels of calcium (hypocalcaemia) in the body which causes cramps and spasms in the hands, feet, and larynx (voice box).

Hypoparathyroidism: It is a disease characterized by low levels of parathyroid hormone. This can cause low calcium levels and trigger tetany.
