Hello. Welcome to JA I will add a preliminary answer to this question, then please reply and we can discuss your issue until you are satisfied. The dizzy feeling you sense is possibly called orthostasis, a change in blood pressure or vascular response as you move against gravity (going from laying supine to sitting or standing, or going from sitting to standing). If you can check your pulse by putting your index finger on your wrist, note if you have a Valsalva response, meaning when you move, if your heart slows down, then starts up racing. This can come from a variety of factors, being dehydrated is the most common, but excessive vagal stimulation from constipation or GERD, or any illness can cause this. Also viral infections involving the balance mechanism, called labrynthitis that is a viral inflammation associated with sinusitis can cause this. Let me know what is going on with you, and I will try to give you a better answer. Dr Frank
