Why with pots does my heart rate get more tachy after i eat? this is rather annoying.

POTS and tachycardia: Pots is a disorder of inefficient blood distribution. Your heart reacts abnormally to keep blood flowing to your brain. When you eat, blood flows to the splanchnic beds and makes less fluid available for proper blood flow. Keep your legs up after you eat, make sure you're drinking a lot of fluids, and pump your arms as if you were doing curls with weights. Good luck!
