Why do you feel dizzy and see when get up too fast?

When you get up too fast, you may feel dizzy and see stars because of a sudden drop in blood pressure. This is known as orthostatic hypotension, and it occurs when your body does not have enough time to adjust to the change in position.

When you are lying down, your blood pressure is evenly distributed throughout your body. However, when you stand up, gravity pulls your blood down to your legs, which can cause your blood pressure to drop. If your blood pressure drops too low, your brain will not receive enough blood, which can cause dizziness, lightheadedness, and even fainting.

In addition to orthostatic hypotension, other factors that can contribute to dizziness and vision changes when you get up too fast include:

* Anemia: Anemia is a condition in which your blood does not have enough red blood cells. This can cause your blood to be less able to carry oxygen to your brain, which can lead to dizziness.

* Dehydration: Dehydration can also cause your blood pressure to drop, which can lead to dizziness.

* Certain medications: Some medications, such as diuretics and blood pressure medications, can also cause dizziness.

* Ear problems: Ear problems, such as labyrinthitis, can also cause dizziness.

If you frequently feel dizzy or see stars when you get up too fast, it is important to see your doctor to rule out any underlying medical conditions.

Here are some tips to help you avoid dizziness and vision changes when you get up too fast:

* Get up slowly from a lying or sitting position.

* Avoid sudden movements.

* Stay hydrated by drinking plenty of fluids.

* Eat a healthy diet that includes plenty of iron-rich foods.

* Talk to your doctor about any medications you are taking that may be causing dizziness.

* See your doctor if you have any ear problems.
