It is a very unheard of nervous system
disorder that prevents the body from being able to properly adjust to the pull of gravity. Therefore, symptoms arise, such as: rapid heart rate upon standing, low or high blood pressure, dizziness, fainting, fatigue, sweating, headaches, shortness of breath, inability to exercise, digestion problems, etc. The symptoms are endless and vary person to person day to day.
