It has been stated by the current research that the astronauts are at higher risk of developing kidney stones while they are in space. It is stated in the study undertaken by the University of Minnesota that the astronauts tend to loose the calcium in their bones and strength in their muscles while they are in space due to the environment that is at zero gravity. The improper utilization of the calcium end up in going to the kidneys putting them at a risk for developing kidney stones.

The survey report has shown that more than 14 American crew members have been found to become patients of kidney stones in last 5 years. The mission seems to become longer and the number also is expected to rise. The reason has been sited that these professionals have exercised in space to attempt to combat bone loss, the lack of gravity makes it difficult to achieve enough resistance to maintain their pre-flight fitness levels.

It has been taken as a major health concern as the amount of time spent in space and living in space is quite longer for an astronaut due to the rise in space stations. The most common type of stones found in theses professionals are the calcium formed stones as the main problem that has been noticed is the misuse of calcium by the body while in space.
