Do I have heart problems?

I am only fourteen but when I ate unhealthy sood such as mcdonalds I smometimes get chest pains and an increase in heart rate shortly after eating. Could I have heart problems and what should I do?

This is very unlikely to be a heart problem.  You may get some heartburn with fatty foods.  I would try eating a healthy diet, cut out the McDonalds, and exercise daily.  If you have chest pains or a very high heart rate with exercise (above 200 beats per minute) you can discuss this with your doctor.  But at age 14, your heart should be completely normal.  Hope this helps.
