Asked for male, 38years old from Visakhapatnam
It sounds like you are having orthostatic hypotension. It is not a serious condition. You must strengthen your leg muscles and use certain postural techniques to prevent the dizziness. You may contact for more guidance on these exercises. Also please get hemoglobin, blood sugar and blood presure checked. Any abnormality in these can also make you feel dizzy.
Hope this helps.
