why sometimes when i stand up i am dizzy this used to happen alot but now it happens every one in a while?

When you stand up, your blood pressure is supposed to raise briefly to counteract the effects of gravity. If your body fails to respond quickly or if you stand up to quickly, then for that instant, you will not receive enough blood flow to the brain, causing you to become dizzy.

If there are no other symptoms, it could just be blood rushing to your head or your inner ear fluid readjusting

could be a sign of mental illness. if you are dizzy, stay in bed, after resting take a bath or eat something that makes you feel better. I choose snacks like chocolate bar or any drink that is preferable during bad moments. Sometimes I have a healthy meal with lots of ingredients to boost health. you can try have a healthy meal, it may help stop the dizziness because feeling dizzy could mean you are dehydated or your body lacks vitamins, so be careful and eat the right amount
