Hello! Welcome on HCM! Regarding your concern, I would like to explain that some slight variations in blood pressure values in both hands are normal due to the anatomical features of blood vessels in our body. So relax, there is nothing to worry about. It is recommended monitoring your blood pressure in sitting position after 10 minutes of total relax. You can measure it in one of your arms. If this difference between blood pressure values in both arms keeps growing, it may be necessary performing a Doppler Ultrasound to examine for possible vessel stenosis or a angio CT scan to examine the blood flow in both arteries. Meanwhile, I would recommend some lifestyle modifications: - a healthy diet (low salt and caffeine intake, low saturated fat) - increase physical activity (walking, aerobics, etc.) - try to reduce weight if you are overweight. Hope you will find this answer helpful! Best wishes, Dr. Iliri
