Dizziness
Mild dizziness is very common in people with hypertension, and it is also an effect of some medications to lower blood pressure. However, people with known hypertension should keep an eye on this symptom when it appears all of a sudden, accompanied by balance problems and difficulty to walk, speak, or perform other motor functions. If you have these symptoms, you need to get urgent medical attention, as it may be caused by a stroke, which is a common complication of sustained high blood pressure.
