What Causes Nausea, Lightheadedness, Fainting Episodes And Headache While Having Low Blood Pressure?

Orthostatic hypotension
Detailed Answer:
Greetings and welcome to Health Care Magic. Thank you for your question. I understand your concern.
Now, normal blood pressure figures standardized for the worldwide population are 100-139/60-89 mmHg. These figures encompass almost every human being with normal blood pressure. It is uncommon, but not abnormal, to have even lower blood pressure in certain times of a day, this being from various changes that happen in organism due to physical activity, psychological stress, normal hormonal changes etc.
The episode you experienced:
it is called orthostatic hypotension. This is a state of confusion, dizziness, blurry vision, near-fainting or fainting episodes, after one briskly switches positions from lying down or sitting to standing. While we sit, blood pools in lower limbs, and once we stand up, this pooled blood takes more time to be redistributed and to supply the brain for a brisk moment, hence the above mentioned symptoms. I would recommend you to not stand up briskly and switch positions gradually. You should stand up slowly and after assuming a sitting up position for one minute. However, just to be totally "in the clear", I would recommend a echocardiogram, to evaluate the structure and size of your heart components.
The final episode of heat feeling and shakiness is a typical (understandable) panic attack after you experienced a worrisome event. There is nothing to worry about for this part.
I hope I was helpful. I am happy to help, if you have followup questions. Please rate the answer, if you do not. Wish you a good health.
Best regards,
Dr. Meriton
