What Causes Anxiety And Fast Heart Rate After Drinking Pepsi?

Recently, when I drink Pepsi, my heart races and i get a fuzzy feeling. Almost like a panic/anxiety attack. If I drink it with a full meal, it doesnt affect me. But if I am only eating a snack or not eating anything at all is when i get this feeling. Is it from the caffeine or sugar?

Hello
Thank You for contacting HCM.

Caffeine is the major content which brings such symptoms It is a CNS stimulant which reduces fatigue & increases alertness level. If used without food then has unopposed effect as there is no food to slow its absorption hence produces anxiety & other symptoms.

Hope this answers your question. If you have additional questions or follow
up questions then please do not hesitate in writing to us.
Wishing you good health.
