Your blood pressure changes when you stand up, sit down, or lay down. For most, its not an issue. For others, their veins and arteries are weakened so the fluctuations can be significant enough to cause dizziness and fainting when getting up. If you have naturally high blood pressure due to genetis, diet, or lack of exercise, chances are your arteries have been hardened and lost their recoil. This is because a persons arteries with high blood pressure are thicker and more stiff than an average persons. So when you stand up, the arteries dont adjust for the drop in pressure, so your blood pressure is allowed to drop significantly. So..... Yes. It is possivle to have both. But the low blood pressure is only temporary when you get up.

A person can't suffer from high blood pressure and low blood pressure at the same time, this is because the blood pressure can only stay the same at one time, you can either have high blood pressure or low blood pressure. But not both at the same time.
