I've been thinking my afib was caused by sudden change to vegan diet. I didn't drink, and wasn't over weight. The only special thing I noticed before my first episode was I sudden changed to a vegan diet 13 days before afib.
Since the diet change, I felt very tired for few days, and also had diarrhea for few days. Then I started to have heavy sweating while I was sleeping at night, that was few days before I had afib also. Then on the 14th day, I woke up at 2am with afib.
Any one had similar experience? The blood test during my first afib showed high Free T4, and though TSH was still within range, but it was doubled than one week before.
I didn't and don't have thyroid problem, and the following blood test after afib didn't show any abnormal Free T4 or TSH.
I asked EP and cardiologist whether sudden change of diet cause my afib, they didn't think so.
