I am 31 years old, overweight nearly 30 kilos extra to my age. Past two weeks i feel like my heart is beating very fast, mostly after my dinner (the only real food i take) , which i take only by 10.30 or so, due to work. I think that my pulse rate is 88 per minute and beats faster than that after my dinner. I dont have nausea, but feels a slight difficulty in breathing after my dinner, when my heart beats faster. Please help me with an advice and suggestion.
