Can low blood pressure be dangerous?

As a new feature of CNNhealth.com, our team of expert doctors will answer readers’ questions. Here’s a question for Dr. Gupta.

Asked by Bella, Buffalo, New York

"Dr. Gupta,
Everyone always talks about high blood pressure, but I have a question about low blood pressure. I am 21, female, eat very healthy, not intensely athletic, but I do cardio every morning and my blood pressure is 90/60. I am dizzy every morning when I wake up, and if I sit for too long, I am dizzy when I stand up. Is this a problem, and is there something I should be doing differently?"


Thanks Bella for writing in. I am a little concerned about what you are writing. Blood pressure can be a tricky thing to understand because levels categorized as “too high” or “too low” in one person, may be normal for someone else.

Once a person establishes his or her baseline number, it’s important to consult with a health-care provider to evaluate its specific impact.

A normal blood pressure is essential to your heart because it promotes and allows healthy blood flow. And you are right–typically you hear people talking about the dangers of HIGH blood pressure because it can lead to heart disease. But low blood pressure, known as hypotension, can be dangerous as well.

What’s too low? Anything below 90/60mm. Experts say that if you have a low BP level and are experiencing dizziness, fatigue, nausea it could be a sign of serious underlying conditions such as a heart condition, blood infection or damage to your nervous system. It is best to be evaluated to determine what could be the trigger.

For those not experiencing symptoms, a low BP level is rarely of concern. You can boost your blood pressure levels naturally by staying hydrated throughout the day and increasing the amount of sodium in your diet.

      Hi Monlam, someone in my family is experiencing similar problem. After reading several articles and discussions I have come to the conclusion that drinking lots of water and increasing sodium in the diet are best home remedy. However if the patient also has kidney issues then consult a doctor before increasing sodium. Hope this helps.

    Hello there , I had an episode a week ago that has me and my doctor puzzled. I had breakfast with my daughter and within one hour of eating I started getting nausia and sever dizzyness. My daughter took me home and then I got worse. I was so dizzy that I could not stand up and could barley see. I also got so cold that I was freezing in 80 degree weather. I got 911 to my place and they said my bp was abnormally low and they wanted to stand me up to try my bp again. I passed out at this attempt and for 7and one half hours I was in and out of conciousness and freezing at the hospital. I was given alervert, something for nausia and it took three bags of water before I felt like I needed to go to the bathroom. The night before I took a half of benadryl. I took a benadryl the other day because I have sever allergys. I woke up and felt kinda dizzy like I was going to fall over. I normally have high blood pressure. So far the doctor said he is puzzled. Could this be a allergy problem as I am very allergic to 7 different drugs? I have taken benadryl before and no problem. So I am not sure that is the problem. My tryglicirides are also high. would appreciate your help.

    Another nurse and I had a long-term-care patient last evening who had a 10 am upper-GI endoscopy, returned with SBP 110, then at bedtime had BP 65/50, and yet he could sit up, stand and walk around and consistently denied faintness. BP subsequently down to 62/58 - not a typo - when he conceded dizzyness after standing for about 30 seconds. (He was sleepy that evening; he has a habit of going out of facility and drinking alcohol, which he has the right to do.)

    Four points of pulse pressure don't seem compatible with function, and yet he did function. How could this occur? We called ambulance. EMTs got 60/40, then over several minutes BP rose to 90/60. He did not go to hospital. This morning, I called. He had remained at facility with low BP but apparently safe.

    The BP cuff did not appear to be malfunctioning. Is that the only explanation?

    Hello I saw this and my blood pressure has gotten as low as 50/20. It's orthastadic, and doctors are fully aware of this yet I have never fainted! I get so dizzy that I fall back to the ground and I see black and red spots in rhythm with my heartbeat. I also have severe headaches, hot and cold flashes and extreme fatigue. I don't think any of the 90/60's should be an immideate concern but do be sure to address to be safe. I've sat there standing up with people taking my Bp and 70/40 is when a normal person without any resistance may faint. Docs say that because I've had this for so long my body creates reactions that refuse to let me faint such as tripling speed of heart rate which could do damage later on. Address asap don't let anything go on to long!!!!

    i'm with my father in the icu right now, and his blood pressure is 78/29. that seems freakishly low to me. what does the 29 part even mean? he has a failing heart, sepsis, cirrhosis, etc and i don't understand what's going on and why this low of blood pressure isn't getting the doctors' attention, it seems like it'd be low enough to give him some freakin blood pressure pills, right?

    I normally have high blood pressure and take medication for it. Recently, within the past few months I have blacked out due to dizziness. I have ringing in the ears,ect. 2 weeks ago I mentioned my last blackout episode to my dr. He contributed it to my blood pressure which that day was 193/109. I spent the evening in the ER last night due to another blackout. THEY said it was due to my blood pressure being 84/52??? What could cause such a drastic change? I have horrible headaches, ringing in my ears, worsening memory,ect. I thought it was possibility from a concussion from 1 of the past 4 falls from blacking out,but they did a CAT scan last night and said it looked ok? Any suggestions?
