A blood pressure of 100/65 mmHg is actually very common and generally not a cause for concern. Since you occasionally feel dizzy, simple lifestyle changes are the best first step. Try increasing your daily water intake, adding a little extra salt to your meals, and avoiding sudden changes in posture by standing up slowly. Regular physical activity can also help. Medications like fludrocortisone or midodrine are rarely needed and are only prescribed by a doctor if symptoms become severe. Please consult your healthcare provider to discuss these safe lifestyle adjustments and to rule out any underlying causes before starting any treatment.
