Low blood pressure is generally good, but it can cause problems, such as fainting or dizziness. It can even be life-threatening in some cases.
What is low blood pressure? This is any blood pressure that is lower than 90 mm Hg (for the systolic or top number) or 60 mm Hg (for the diastolic or bottom number). Dehydration or serious medical disorders can cause it. You need to determine the cause to get proper treatment.
