I am sorry i don't know your name.
Thank you for your kind words about my writings:)
The dried pineapples i procure are exactly produced in Costa Rica, in the location called Limon! And they are delicious. It is now a period when no dried mango is available, at least of the type i prefer, so i enjoy a piece of Costa Rican dried pineapple on a daily basis!
Yerba mate is mostly consumed in Argentina, Uruguay, Paraguay and Brazil. Yes, i suppose it may facilitate arrhythmias or increase respective vulnerability. I only take it once a day and have gradually reduced the amount I use in my morning yerba brew to the point where it is almost imperceptible. It's more an experience than actual consumption:) And still you are right, it can do it, but i am not sure i am ready to get rid of it... Yerba mate is probably the last and only suspicious product that i consume.
Indeed i am always looking the way to understand the problem, i never run to a clinic to get help. In the past i also practiced intermittent fasting, and i am now considering the possibility to resume it. But i am not sure my body will take it. On the other hand, the heart feels very content when i am empty inside.
You know, meanwhile, and i failed to have mentioned it, some new data transpired. I had an appointment with a pulmonologist, who appeared to be quite more understanding type of a doctor. I had an X-ray and CT scan and there seem to be a problem with my lungs. Emphysema was ruled out but there can be a fibrosis or other condition which i will find out tomorrow, if the doctor has arrived to a conclusion. It may have its part in the situation. Also, the scan revealed calcification of pulmonary arteries, a severe one which can definitely influence the situation. So i guess, yerba mate can be the least of my concerns:)
Itchy problems can be caused by so many things! you are lucky you found the cause.
I heard Costa Rica is a beautiful country with amazing nature!
Hope you are feeling well and wish you well!
