When you detect unusually high readings during pregnancy,
you should measure again after at least four hours. If the
reading is still too high, consult your doctor or obstetrician.
Physical activity including eating, drinking, and smoking as well
as excitement, stress, and many other factors can influence
blood pressure results.
HOW TO EVALUATE YOUR BLOOD PRESSURE
The World Health Organization (WHO) has created the
following guide for assessing high blood pressure (without
regard to age or gender). It is important to note that various
factors (e.g. diabetes, obesity, smoking, etc.) also need to be
considered. Consult with your physician for an accurate
assessment and diagnosis of your health condition.
