I have an artificial heart valve, fiite 2 year ago - it is a Pigs valve. I am very well & fit.  Have recently taken to eating dark Chocolate 85% Cocoa thinking it would improve health even more! But always get slight pain in chest pain after eating 2 large squares of this. I do not get this pain at any other time?
Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about heart related pain. Your chest pain is associated with eating dark chocolate. Dark chocolate is having larger quantities of cocoa. And this ingredient is known to cause gastritis. And this gastritis is the likely cause for your chest pain. So better not to take large quantities of this dark chocolate. You can eat in small pieces over 1-2 hours.  Chat Doctor.  You can take antacid like pantoprazole if you feel similar kind of pain. 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.
