1.Measuring Blood Pressure
A cuff linked to a special device tightens around your arm to get two measurements. The top number, or «systolic,» notes the pressure your blood makes against your artery walls when the heart beats. The bottom number, or «diastolic,» measures the pressure between beats, while the heart is relaxing and filling with blood. You can get readings in your doctor’s office or at home.
2.Symptoms
Your brain usually shows the first symptoms of hypotension. Besides dizziness and nausea, your spirits might be low, you might lack energy, and find it hard to think straight. Some people feel lightheaded enough to faint or notice cold, clammy skin, faster breathing, blurry vision, or chest pain. If your low pressure is caused by dehydration, you also might feel unusually thirsty.
