"Adam Rainer was born in Graz, Austria to average-sized parents in 1899. When WW1 broke out, Rainer tried to enlist in the army, but at 4’6.3’’ ("average height for British recruits in WW1, 1914, was 5'5)
"Rainer (pictured right) suddenly began growing at an alarming pace. Over the next decade, he grew from just under 4’10’’ to a shocking 7’1’’. During this period, Rainer also began developing a severe spinal curvature." (While Acromegaly does cause spinal curvature, spinal curvate could also be brought on by scoliosis from having low estrogen).
". A few months after surgery, Rainer was measured again. His standing height had remained the same, though his spinal curvature was more severe, indicating that he was still growing, albeit at a much slower rate."
"He died, aged 51, measuring 7’8’’ "
What causses epiphyseal fusion is still unclear:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4397276/but doctors *may* think it's estrogen (can't believe it's 2017 and we still don't understand this)
--------------------------
Hypothesis 1: The tumor originally caused hypothyroidism (which can cause lower testosterone and lower GH) which was the original reason for his dwarf height. Then, as the tumor grew, it started pressing up against the thyroid in a different way and caused the overproduction of GH (but perhaps still no testosterone)
- But what about the 7 inches he grew after the tumor was removed and was after maturity? Was this simply growth happening because his growth plates had never fused from having low testosterone the whole time? Could be, this would've placed him from 4'10 to 5'5, meaning the ~7 inches he was originally missing out on all along. Hazy theory though.
Hypothesis 2: There was far more wrong with him, and the doctors of the time just couldn't diagnose it.
Hypothesis 3: The dude stopped growing and newspapers & old media just didn't report any of this accurately and probably focused on the hyperbole.
Whatever happened, sounds interesting.
Also to note: Rich Piana started using HGH at the age of 24 (
http://www.naturalheightgrowth.com/2016/10/12/bone-growth-effects-growth-hormone-rich-piana/) and has had no height increase (but other HGH side-effects). For Adam Rainer to suddenly begin producing HGH at 25 and still grow really does seem too late for someone with a normal hormone system. Something else had to be off.
