What Causes Lethargy, Lightheadedness, Blackouts And Dizziness?

Lately when I ve been feeling really lethargic and light headed, when I ve been sitting down for a while then stand up I go really light headed and dizzy and feel like I m going to pass out, also I get like blind spots in my vision when this happens it was going on for around a month. I ve started drinking more water, eating healthier and working out, it has helped however if I have a lazy day it comes back. I told a friend and they suggested it may be my blood pressure.

Hello,

Dehydration and less than optimal nutrition are 2 of the most common causes of these types of symptoms.

Another could be LOW blood pressure, however, you are theoretically correcting the problem with drinking more fluids.

However, there's nothing wrong with having your BP checked on the times you do feel faint, etc. and see if at that time you do have low pressure running.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Regards,
Dr Dariush Saghafi, Neurologist
