What causes a sudden feel of dizziness?
Patient: my son is 15 and complains that he feels dizzy whenever he stands up suddenly, even just from a sitting position. This happens on a daily basis. He has taken quite a growth spurt and is always hungry. His diet is resonably okay although fruit and vegetable intake is not as good as it should be but he eats a lot of protein and fortified cereals Doctor: Hello and welcome to " Ask a Doctor" service.I have read your query and here is my advice.Orthostatic hypotension may be a condition to consider.Lower blood sugar levels also is a possibility.Discuss with the Pediatricin for these issues.Hope this helps.Feel free to ask if you have further questions.
