Dear Cherie,

Low blood pressure is a niusance, but not a health risk. The usual symptoms are things like tiredness, dizziness when you stand up too quickly. There are no medications to raise blood pressure, but Coca Cola, coffee and any caffeine-containing drinks will temporarily raise blood pressure.

You do not say how low your BP is, or how consistent the reading is. If you have sudden unpredictable drops in your BP, then your risk would be in matters such as having a dizzy spell whilst driving, or operating machinery. If you have a spell of low BP here causing dizziness, obviously you could injure yourself.

You would be wise to see your doctor for a complete checkup to try to determine if there are any reversible causes – eg, many women have heavy periods, and the blood loss can cause low BP. The other causes your GP will know about, and will arrange the necessary examinations and tests. The other important thing to consider if your low BP only happens occasionally, is whether you have a heart rhythm irregularity. Your GP will be able to advise you about this too.

Good luck.
