Detailed Answer:


I would like to explain that lightheadedness with nausea may be potentially caused by blood pressure fluctuations most likely high blood pressure.

Coming to this point, it is necessary to closely monitor your BP values and refer them to your attending cardiologist or internist.

A digestive issue and also abstinence symptoms due to alcohol withdrawal should also be considered during the differential diagnosis workup, but if this clinical symptomatology persists even after excluding digestive problems, then it is necessary to consult a neurologist just to be sure that no adverse implications from afib arise (possible cardioembolic event in the cerebrovascular system).

It would be a rational approach discussing with your cardiologist about a potential addition of anti-thrombotic medication in your ongoing therapy.

I believe that your main goal after that would be to control your body weight as it may give rise to arrhythmia, hypoventilation syndrome, and diabetes.

Hope to have been helpful to you!
