I am in the process of joining the Armed Forces and during my health check the guy casually mentioned that I have quite severe Anterior Pelvic Tilt and that it causes me to run oddly - he said to stretch, but gave me no further advice. I have previously done the health check a few years ago but decided to postpone entrance. Anyway, they measured me (at the same time of day, so no gravity shrinkage) at 5 foot 9 & a bit [176cm], now two years later I was measured me at 172cm. No shoes on either occasion.
I asked the guy, who was not a doctor, how this could be - he said it was 'maybe' due to APT and that I need to fix it or it'll get worse and cause me lower back/knee/neck problems during training, possibly further height loss, especially caring heavy backpacks etc. Height loss at my age is concerning me as I am only 20yo and have consistently measured around 5 foot 9 since I was sixteen.
I have been researching it since and have not found any connection between APT and height loss past an old forum post on some website, no academic or notable data building a connection between APT and height loss. What is the general consensus about APT and height loss, specifically is it reversible?
Finally, is there any known connection between APT and intermittent migraines emanating from the neck region to the crown? The only data I can find is mostly lays giving anecdotal accounts on bodybuilding forums about APT causing a whole host of problems.
