Welcome to Healthcare MagicLow BP
could be seen in a number of conditions. You may be having orthostatic hypotension
where you may feel a but giddy after you immediately stand up from lying down position. You need to be well hydrated to prevent the symptoms. Avoid getting up quickly, rather sit by the edge of your bed and actively move your feet as though you are pushing down and off the gas pedal of your car. Do this for 5-7 times and then get up slowly. Get your BP checked in sitting position, after 15 minutes of rest by your Doctor to confirm low BP. The cholesterol
needs to be reduced. Are you taking medications for that. Eat plenty of fresh fruits and green leafy vegetables as hey help remove excess cholesterol from the body as well. Get an ECG immediately as even without chest pain
you could be harbouring heart disease
which may not be detectable till you get an ECG and ECHO.
