Hello. I found out yesterday that I weight 200lbs. My height is 5"4". I been feeling light head and dizzy and it hard for me to get out the tub sometimes. I just want to know am I obese.

At 5'4", 200 pounds is considered morbidly obese.

Yes..

It is up to your doctor to decide if you're at risk for any health issue. One can be perfectly healthy and still obese, even morbidly so. You should have a conversation with your doctor as to what your best course of action is. Should you actively try to lose weight? OR are you healthy enough to stay as you are? Judging by what you included, I would suggest that talking to your doctor about weight loss and effective methods might be a good course of action for you.
