I'm 16 and have recently been diagnosed with high blood pressure, recently ive noticed a visible pulse in my stomach, normal? i have bad anxiety

Pulse: That pulse is the result of your heart causing dilation of the abdominal aorta and periodically increasing the volume of intestinal blood. You'd be dead w/o it. Strange to have hypertension at your age without renal or other serious involvement. Be sure to see a cardiologist or internist to R/O things like a pheochromocytoma. You should be anxious until you solve the BP problem.
