HyperPOTS
HyperPOTS is a type of POTS characterized by high adrenaline. This is the type of POTS that I have so I’m speaking from my experience.
Some adrenaline symptoms:
Tremors
Pupil dilation issues
Muscle rigidity (I assumed that it was muscle stiffness, but it is more than that. My muscles don’t give how they’re supposed to)
Inability to tolerate medication (because adrenaline interferes with medication)
Lack of hunger or thirst sensations
Food and water make me nauseous
Constantly being anxious
Racing thoughts
Not being able to sleep
Diagnosis
Tilt Test
I had adrenaline symptoms during the test. Being tilted gave me tremors
Catecholamine bloodwork
Not 100% accurate
Holter monitor
My heart rate spiked to 170 while waking up a single flight of stairs. With that I also had heart arrhythmias. That high of a spike + arrhythmias is indicative of adrenaline
Treatment
Beta blockers are usually the first medication to try for this
Atarax is a good option if you can’t handle beta blockers. However, it may make heart arrhythmia’s worse. If this is something you/your doctor is considering, you should wear a holtor monitor and verify that it is safe for you.

My experience
Many neurologists don’t know that this exists or that it requires to be treated differently than the other types of POTS.
HyperPOTS can’t be treated only with normal POTS treatments. If you don’t control the adrenaline, your POTS won’t improve. I was treated only for POTS for over a year while I continued to get worse.
