What causes "POTS" (postural orthostatic tachycardia syndrome) in EDS? |

"Physicians propose that these syndromes occur
together due to abnormal connective tissue in dependent blood vessels
in those with EDS, which permits veins to distend excessively in
response to ordinary hydrostatic pressure. Simply put, this connective
tissue abnormally allows excessive amount of blood to pool in these
patient’s lower limbs when they stand." (Rowe.et.al. 1999)
