Can You Come for a Visit? My ME/CFS Says No
My daughter and son-in-law just had a baby last week. We are thrilled. But we won't be able to see the baby or hold her any time soon. We won't be able to take over little gifts or help out with housework or babysitting.

    Reduced blood volume at least in POTS has been demonstrated to be associated in mahy with measurably reductions in aldosterone and elevations in angiotensin II. Kidney dopamine salt handling has also been implicated.

    Nice video about the Cardiovascular System in Space for 14-18 year old students :):

    Weightlessness/low gravity environments cause all sorts of weird and wonderful biological changes. To claim it is all down to the HPA axis is a BIG stretch.

    For example, growth and development of bacteria and plants are changed in low-gravity environments is changed and they don't exactly have a HPA axis. ;)

    I had always been of the opinion that ME is caused by individuals being subject to mysteriously increased gravity.:nerd:

    My personal gravity field is about 4 times stronger than that of somebody who isn't sick. :p

    Could this be connected to the very common ACE-deletion, or mutations, seen in most people with ME/CFS?

    The ACE-deletion was so common among ME/CFS people, so Yasko exchanged the analyse of ACE in favour of another SNP. It is analysed in the 23andme test though not presented in the panel by www.GeneticGenie.org

    Micro black holes. That also explains psychobabble. They get too close too often and it drains their brains too. ;)

    I studied space biochemistry a little back in 2001 or something, but I have forgotten it. Much of it has to do with stresses, including shear stress, on muscle and bones. The cells respond to stresses by maintaining structural integrity in the tissue. Things become weak without gravity. I don't recall much more, doh. Nerves do register stress, so it will impact on brain response.

    Another topic of interest in extreme biochemistry is arctic explorer metabolism. Their metabolic rates skyrocket. They also consume fat and sugar at a massive rate. There might be some lessons there for us as well. This was also covered in my biochem lectures, and the other extreme one covered was sumo wrestlers. Super fat, super fit, no heart disease risk.

    You know, this explains a lot!

    Honestly I think it's obvious what is causing this in astronauts, sudden and severe physiological and psychological stress caused by space travel. Humans like other life on Earth are not evolved to be in space and this imposes a large stress burden on the body.

    Is long-term or sudden severe stress a possible theory for what causes ME/CFS in certain people?

    When i first got ill i was convinced of that. If i wasn't glued flat to a bed, i was glued to a floor. Resting my head on a table wasn't good enough as the gravity would keep pulling me to the lowest point in the room and once i was there it was like pulling against a strong magnet.
    I used to say there was a black hole hiding under the house.... and every other house i've lived in since.
    I'm guessing the nhs don't stretch to giving out anti-gravity suits :alien:
