First, I would like to thanks those who have created this forum, and all the dedicated members who share a lot of useful information here. I have just found this forum last week. I am 49 y/o male from Quebec province, in Canada ( I am a French Canadian, you may notice it in my English writing) I have POIS symptoms since puberty. Yes, that means 36 years of POIS.
Being a health professionnal ( I am pharmacist), i have found many ways to lower the intensity and duration of my acute POIS phase ( I have used my knowledge in human physiology, in pharmacology, and also my expertise in natural products and vitamins, to do so ) In the last ten years, i have also developped a way to monitor the acute POIS phase, which last now for about 24 to 48 hours (was longer, and much harsher, when i was younger ). I now take my blood pressure as a sign to know when it starts (there is, for me, a delay between ejaculation and symptoms onset). Basically, hypotension (low blood pressure) is an objective sign that i am in acute POIS phase (but, for sure, no need for myself to mesure my BP in order to know if I have POIS or not, as you all know! It is more about having a scientific approach, and an objective criteria to define the progression of the different phases of my POIS ). Through the years, i learned that if my systolic pressure (first figure) is below 105 and my diastolic pressure (the second, smaller figure) is below 70, i am not feellng well, and the POIS is still peaking. At 103/67, for example, i feel exhausted, i have anxiety and irritability, less concentration, orthostatic hypotension (head rush), and so on. At 110/71, i am feeling much better - not full recovery yet, but the worst is behind. Hypotension, for me, is in part responsible for many of the symptoms I have - athough not all of them. Low blood pressure decreases the brain's blood flow supply. Brain cells are very dependant of a constant supply of glucose and oxygen to function properly, and the cerebral tissues also need a constant cleaning to maintain optimal functions. Decreased BP also explains exercice intolerance.
There is more causes and more symptoms to POIS than hypotension, and I plan to eventually share more about how I understand POIS, but for now i am reading and integrating all the new info I find on this forum. Needless to say, my brain is on fire since last week, blinking like a Christmas tree ;-) , from all this info I get at once, after having no other source of info than myself during all those years.
I suppose, considering my current model for POIS, that many people in acute POIS phase may have a low blood pressure as I do. I have searched this forum for "low blood pressure" and fund very little mention of that. Let me know about it if you do have made some BP during your POIS worst days, and what results you have get.
Thanks,
