What causes dizziness while standing or lying own?
Patient: when lying down for a while, and then standing up suddenly, or vice versa... i get dizzy for a bit.. a feel strange in my chest, like there is a small pressure inside.. should i be concerned?                                                                                                                                      and another thing..  I found out /saw that I was breathing very shallow .. and somewhere i've read it can cause high blood presure and all kind off bad side effect to the human body... i wonder does that have anything to do with it? Doctor: Hello, Thank you for trusting HCM.you might have postural hypotention, which will give symptoms like the one you have, its due to fast changes in your blood pressure and your heart is trying to compensate for those fast changes. its not dangerous per se but you have to be careful not to change posture so quickly you might lose your balance and fall down hit something that would be dangerous. So once you wake up take time setting at the edge of your bed before you stand up same for laying down. for more details and proper diagnosis please refer to a cardiologist. Dr Nazzal
