Spaceflight Osteopenia

Spaceflight Osteopenia is a condition where astronauts experience a decrease in bone mineral density during spaceflight. This is caused by the lack of mechanical loading on the bones due to the microgravity environment. The lack of gravity causes the bones to lose calcium and other minerals, making them weaker and more susceptible to fractures. Spaceflight Osteopenia is a significant concern for long-duration space missions, as it can lead to an increased risk of fractures and other bone-related injuries. Astronauts on the International Space Station (ISS) are required to exercise for several hours each day to help mitigate the effects of Spaceflight Osteopenia. Additionally, researchers are studying various medications and supplements that may help prevent or treat this condition.
