What happens to the human body if it is in space too long?

The rapid change of gravity in space can cause a loss of bone density of up to 1% a month. This could lead to osteoporosis-related fractures and long -term health problems. Lack of gravity can also cause body fluids to shift upwards, which may cause swelling, high-blood pressure and vision and organ problems.
