Im 23 years old and recently I've noticed that whenever I eat a big meal or heavy food from restaurants, I can feel my pulse increase in my neck. What could be causing this?

Increased pulse after heavy meals can be due to a condition called postprandial tachycardia. This can happen when the body redirects blood flow to the digestive system to help with the digestion process, causing the heart to beat faster. To help with this issue, you can try to eat smaller, lighter meals and avoid foods high in fat and sugar. Additionally, staying hydrated and practicing relaxation techniques may also help.
