It could be that POIS ---> hypovolemia ---> SNS activation ---> vasoconstriction ---> increased peripheral resistance
Or POIS ---> inflammation --> increased blood plasma viscosity --> alterations in blood flow.
Or POIS ---> blood pressure alterations ---> changes in blood flow
Or POIS --> mast cell activation --> cardiovascular problems
Low-flow POTS?

Hormone changes ---> hypovolemia.
Altered adrenergic states ----> bloodflow changes.

AVP constricts arterioles, which increases peripheral vascular resistance. https://en.m.wikipedia.org/wiki/Vasopressin

Smooth muscle NO/calcium signaling leading to altered peristaltic pumping of blood?

Decreased intracellular calcium stimulates renin release via calcium-inhibitable adenylyl cyclase (https://pubmed.ncbi.nlm.nih.gov/17088449/)
Title: Weird vascular symptom. Vasoconstriction?
Post by: Clues on June 02, 2021, 09:13:50 AM
I have a symptom whereby it feels like my blood flow is somehow impaired, especially in my arms and legs. It correlates with POIS, but doesn't quite go away even when abstinent for long periods. It's especially severe in cold weather.

It seems to fit the description of vasoconstriction (https://www.healthline.com/health/vasoconstriction). Anyone else have this? Any known treatment that works specifically for this issue? Any ideas why it happens?
