I hope you are doing well
I would suggest to avoid fast this ramzan, because there will be medications you have to take on time and there will be follow up for the syndrome.
And I think you are permitted to avoid fast
because if unattended this condition of yours may lead to excessive rapid heartbeat, which is not good, it may land you in hospital and may cause serious complications.
I think you will understand
but if you don't, you can get in touch with me.
