Why Your Blood Pressure Won’t Come Down — Because of This ONE Habit | Dr. Mandell

Описание: You’ve cut the salt. You’re walking daily. You’re trying to eat clean. So why won’t your blood pressure come down? In this video, I explain how one common eating habit—frequent meals and late-night eating—may keep insulin elevated throughout the day, influencing your kidneys, nervous system, blood vessels, and even your nighttime blood pressure patterns. Elevated insulin increases renal sodium reabsorption, stimulates sympathetic nervous system activity, reduces nitric oxide availability, and contributes to vascular stiffness. When insulin remains chronically elevated, your body may retain more fluid, increase vascular resistance, and blunt the normal nighttime blood pressure dip. I break down the physiology step-by-step and give you practical strategies to help restore hormonal balance, improve endothelial function, and support healthier blood pressure naturally.
