Thanks for your question on Healthcare Magic. I can understand your concern. Since you are obese, you should definitely rule out heart diseases first. So get done ecg, 2d echo and stress test (trade mill test). If all these are normal then no need to worry for heart diseases. Sometimes stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relax and calm. Consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic (propranolol and flunarizine) drugs too. Don t worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
