POTs and Flared Symptoms After Blood Drawn or Injury

Having POTS symptoms flare after having blood drawn could also be a result of decreased blood volume, depending on how much is taken.

Since developing POTS, I've started fainting when getting blood drawn if I don't lay down during it. Doctors have insisted on saying it's a pain/sight of blood thing that alot of people experience, but I know it's not. Makes sense that losing blood volume when u already don't have "enough" would trigger POTS. I've had times where without looking at the needle, my vision literally starts getting blurry the second they start drawing blood out of my arm

in that case, I would bet that a large part of it is blood volume issue. Losing 2 vials of blood isn't enough to give most people symptoms, but your brain with pots can easily go into panic mode... "uh oh we're losing blood, better boost the pulse & bp" when you have barely lost any blood. You don't have to share this with me/everyone, but it might be good to consider if your period also triggers your pots. That would be a good way to tell if the trigger is losing blood In general

YES! Even with very little blood drawn, my heart rate skyrockets and I feel absolutely awful for the rest of the day.

Is you salt intake good? Remember you need electrolytes especially with pots what I recommend is also managing stress! Pots had to do with the autonomic nervous system pots usually develops when a super stressful event has occurred
