Why do get dizzy when i stand up

The rate of death over 10 years was 29 percent for people with delayed orthostatic hypotension, 64 percent for those with orthostatic hypotension the more serious form of the disease and 9 percent in people without either condition.

People with delayed orthostatic hypotension who also had diabetes at the beginning of the study were more likely to develop the full condition than those without diabetes.

The most common symptom is lightheadedness or dizziness when you stand up after sitting or lying down. Symptoms usually last less than a few minutes. Occasional dizziness or lightheadedness may be fairly minor — triggered by mild dehydration, low blood sugar or overheating.

Dizziness or lightheadedness may also happen when you stand after sitting for a long time. If these symptoms happen only occasionally, there's likely no cause for concern. It's important to see your doctor if you have frequent symptoms of orthostatic hypotension because they can signal serious problems. It's even more urgent to see a doctor if you lose consciousness, even for just a few seconds.

Keep a record of your symptoms, when they occurred, how long they lasted and what you were doing at the time. If these occur at dangerous times, such as while driving, discuss this with your doctor.
