Hello and welcome to the forum.
First, an RVSP of 32 is essentially normal. Second, echo tests can not diagnose pulmonary hypertension (a lot of doctors unfortunately do not appreciate this). Third, being overweight can certainly cause mild pulmonary hypertension and weight loss would help a lot.
Finally, and most importantly, DONT WORRY, sounds exceedingly unlikely that you have PH. Hope this helps your worries.
Good luck.
Dr. Rich
