Hi, Thank you for posting your query. I have noted your symptoms. We need to exclude postural hypotension- a drop in blood pressure on standing. This can be found out by checking blood pressure in supine (lying down) and standing position. In addition, we also need to exclude a diagnosis of anemia (lack of blood). This can be done by checking hemoglobin level in blood. If low, it can be corrected. Otherwise, there is no need to worry. I hope my reply has helped you. I would be pleased to answer, if you have any follow up queries or if you require any further information.
