Why do i be diizzy ever time i get up or ever take a step.this all the time. it last for good while?

Dizziness: Dizziness when getting up may be due to low blood pressure. (do you take any BP meds?) dizziness with movement may be a balance problem or an inner ear problem (labyrinthitis). Since this problem presents an increased risk for falls, see your doc to be evaluated & treated. Be sure to take all your medicines, including supplements, with you so doc can see if any may be cause.

Many possibilities : If you feel as if you are moving or things around you are moving you have a symptom called vertigo an that is a problem with your inner ear. If you feel lightheaded or as if your going to pass out that may be a problem with blood pressure or dehydration. Sometimes anemia can cause symptoms like this as well. Best to see your doctor for an evaluation and blood work.
