Is 90 over 50 a bad blood pressure?

90/50 mm Hg is considered low blood pressure and is typically not a cause for concern unless you are experiencing symptoms such as dizziness, lightheadedness, or fainting. However, low blood pressure can sometimes indicate an underlying medical condition, such as dehydration, malnutrition, or a heart condition. If you are concerned about your blood pressure, it is best to talk to your doctor.
