Yes, a blood pressure reading of 138/81 mm Hg is considered high and could be indicative of hypertension, or high blood pressure1. According to the new guidelines, high blood pressure is defined as a reading of 130/80 mm Hg or higher for all adults1. Since 138/81 is above this threshold, it suggests that the individual may be at increased risk of developing health complications associated with high blood pressure. It is essential to consult with a healthcare professional for proper diagnosis and treatment recommendations.
