Health Tips:  Does it ever happen to you that when you suddenly stand up, darkness appears in front of your eyes for a few seconds? This happens to many people and usually happens when we suddenly stand up from a sitting or lying position. However, very few people pay attention to the reason behind this. Therefore, we are going to tell you about its causes (Causes of Blur Vision). Some of these are very simple reasons, which you can remove yourself, but some situations can also be worrisome. Let's find out. 

Dehydration

Dr. Agarwal said that orthostatic hypotension or dizziness is a condition in which blood pressure drops rapidly due to a change in our position. There can be many reasons behind this, but the most common reason is lack of water in the body. Due to dehydration, the body loses volume. Due to which, BP drops and dizziness occurs when one stands up suddenly.

Side effects of the drug

This can also happen due to the side effects of some medicines. Especially, diuretics and antihypertensive medicines also cause blood pressure to not be regulated and dizziness can occur on standing up suddenly.

Heart diseases

Dizziness on standing can also be caused by an underlying heart problem. Sometimes the heart is unable to pump blood properly due to heart valves and bradycardia. This causes a lack of oxygen in the brain and can cause dizziness.

Diseases related to the nervous system

Sometimes blood flow and blood pressure cannot be regulated due to disorders related to the nervous system, such as Parkinson's disease. This can also cause dizziness when standing up suddenly.

Anemia

Anemia is a condition in which the count of red blood cells decreases . Due to this, less oxygen reaches the brain and dizziness can occur.

Old age

Sometimes due to old age or being on bed rest for a long time due to some disease, the body is not able to control blood pressure properly. This can also cause dizziness when standing up.
