Hi
I am 30 yr old male.
I have noticed heavy breaths,fast heart beats ,slight head ache and dizziness when i have my meals.whether be it lunch or dinner?
I also have low BP due to sudden weight reduction by myself.
Weight reduction happened after i did dietary changes with exercising.
Now i have Low bp..but every time after meals i get this imbalance.

Hello. Nobody can diagnose through internet but generally speaking, there is an association between eating and cardiac arrhythmias. In some patients the activation of the vagal nerve produced with the esophagus movement and gastric distention, can trigger extra beats (premature auricular complexes or APCs, and ventricular premature complexes or PVCs). If you get several of these extra beats it can produce shortness of breath and dizziness. One of the reasons that you are having these new symptoms may be related to an increased stress level or to your strict diet. Very restrictive diets can impact in the amount of electrolytes and vitamins that you are receiving and your potassium or magnesium level could be low. I would suggest you to keep a good intake of those electrolytes (banana, nuts, coconut water, beans, etc) and avoid coffee and alcohol intake. If your symptoms persist, consult a cardiologist as a 24-48 hours electrocardiogram (holter) will very useful to define if your symptoms are associated to an arrhythmia or not. Good luck.
