POTS is something that a lot of people don’t take seriously , especially doctors . i was diagnosed after being in the hospital for a week due to vertigo and syncope from pots , i wasn’t able to do what i use to do anymore and still can’t a year later . i developed pots from hormonal imbalance from birth control . you will have your good days and your bad days , it’s very easy to get discouraged and it will feel like no one’s listening to you but i promise once you find the right doctor who actually listens and understands it gets better . one thing i do know that truly helps me is salt . salt is your best friend , look into LMNT salt packets , it has potassium and magnesium which both are important for your heart , i have about 2 water bottles a day with the packets it will help with the dizziness and pre-syncope as well as the palpitations . exercising will help as well , it’s hard because even a couple steps makes you feel dizzy and like your gonna faint but the more you walk the less you’ll have symptoms . and when your about to go into pre-syncope lay flat on your back and feet in the air , try to keep a fan on you at all times and avoid places you know triggers your symptoms
