There are several possible reasons why you may experience symptoms of lightheadedness, dizziness, or palpitations upon standing. You will have to provide some more details in order for me to give you a very helpful answer.

For example, there is a syndrome called Postural orthostatic tachycardia syndrome (POTS), where a change from lying or sitting toan upright position causes an abnormally large increase in heart rate, called tachycardia.

This tachycardic response is sometimes accompanied by a decrease in blood pressure, lightheadedness, pre-fainting, dizziness, exercise intolerance and extreme fatigue.

A visit to your doctor is the first step in helping to determine the cause of your symptoms.
