I am a 20 year old female that experiences dizziness, lightheadedness, nausea, pressure and a pounding heart. Can you explain?

I am a female and 20 years old. I get dizzy or lightheaded several times a day and most of the time its severe. I can't stand up and I feel pressure on my body, my head and stomach, and my stomach hurts most of the time. I feel like I want to throw up and sometimes I actually do. It's as if someone is sitting on my stomach and putting pressure on it. I have read some articles and noticed that this could be linked to heart failure? Also, I constantly feel my heart beat, as if its pounding outside my chest, and it increases very much and sometimes actually hurts during emotional times. Would you please explain all this? Thank you.

Reynolds M. Delgado III, MDThis sounds like neurocardiogenic syncope which is not serious. I suggest you keep a log of your blood pressure then take it and see a primary care or general doctor and they should be able diagnose and treat this. [However, if the symptoms become more severe or change, don't hesitate to seek urgent care immediately.]
