The researchers have informed us about this as a warning that it could be a '**big concern**' for future missions of [astronauts](https://www.mindstick.com/news/1579/china-s-capsule-shenzhou-14-with-three-astronauts-will-be-launched-in-june). ``` HIGHLIGHTS Astronauts struggle to regain bone density after a space mission. Around one to two percent of bone density is lost every month in space. It is considered as ‘the silent disease’, becoming a ‘big concern’ on Earth. ``` According to the previous research due to the lack of gravity the legs takes off the pressure when it comes to standing and walking, as a result of which astronauts lose between one to two percent of [bone density](https://yourviews.mindstick.com/story/3546/why-do-we-lose-bone-density-as-we-age) for every month spent in space. In order to find out the ways astronauts can get recovered once their feet are back on the ground, a new study came into scenario. In this study, they have scanned the wrists and ankles of 17 astronauts before, during and after a stay on the [International Space Station](https://www.mindstick.com/news/1494/nasa-insist-the-international-space-station-unaffected-by-ukraine-russia-war). ![The Silent Disease which Becomes a ‘Big Concern’ for Astronauts](https://www.mindstick.com/usernews/645947/a9213538-bc4e-40d6-85ef-56994e94a47b/images/12dee032-eb1f-40f7-832d-28973e63276b.jpeg)\ Also Read: [SpaceX’s Starship Said to Face Hinder in Originating, NASA](https://www.mindstick.com/news/1663/spacex-s-starship-said-to-face-hinder-in-originating-nasa) Well, it has been found out the bone density which is lost by astronauts was equivalent to how much they would shed in several decades if they were back on [Earth](https://www.mindstick.com/news/1337/trojan-asteroid-has-been-in-earth-s-orbit-and-expected-to-stay-for-3-500-years). The researchers also found that nine of the astronauts’ shinbone density had not fully recovered even after a year on Earth .The ones’ who ranged from four to seven months on [space](https://www.mindstick.com/news/1700/approval-by-the-us-for-spacex-s-starlink-internet-service-for-moving-vehicles), were the slowest to recover from this bone problems.\ '**The longer the time is spend in [space missions](https://answers.mindstick.com/qa/115289/how-does-spacex-plan-to-ensure-human-safety-during-crewed-space-missions-and-flights), the more bone will get lose,' 'Will this continue to get worse with time or not? We don't know**,' Boyd told AFP. As per a doctor, '**Even after the two hours of sport in a day, it is like getting bedridden for the other 22 hours**.' A 2020 study has predicted that a three-year spaceflight to Mars would lead 33 percent of astronauts at risk of getting infected with osteoporosis. According to the head of medicine research at **France’s CNES** [space agency](https://answers.mindstick.com/qa/32252/cryogenic-engine-for-upper-stage-of-gslv-mk-iii-was-successfully-tested-by-which-space-agency), **Guillemette Gauquelin-Koch** said that the weightlessness that is experienced in space is '**most drastic physical inactivity**'. Well, the astronauts who are fit and are in their 40s had not noticed the drastic bone loss in the body. According to **Boyd**, the Earth-bound equivalent osteoporosis is known as '**the silent disease**' and it is visible mostly in the astronauts who have returned from a long [space mission](https://answers.mindstick.com/qa/100622/which-country-recently-conducted-a-successful-space-mission-to-the-moon). --- Original Source: https://www.mindstick.com/news/1703/the-silent-disease-which-becomes-a-big-concern-for-astronauts Copyright © MindStick Software Pvt.
