[|Human|] Hi, my blood pressure was just measured today and it was 90/40. I am an 18 yr old male that is 135 lbs and 6 ft tall. I get some exercise, but not enough. Is this low pressure something to be worried about? I sometimes get lightheaded when I stand up and my vision goes almost completely black for 1-2 seconds after standing. This doesnt happen often.
[|AI|]  Hi, Thanks for asking. Based on your query, my opinion is as follows.1. Anything below 90/60 is worrisome.2. It can lead onto postural hypotension, risk of syncope and any fall could be dangerous.3. You are already having few symptoms, and blood pressure needs to be increased. Increased fluid intake with salts and venous stockings of lower limbs is beneficial. Mild corticosteroids can also increase blood pressure. Detailed evaluation necessary to assess the cause of low blood pressure. More details necessary for further opinion. Hope it helps. Any further queries, happy to help again.
