Blood pressure is the force your blood exerts on artery walls as your heart pumps. Normal readings fall below 120/80 mmHg. Stage 1 hypertension begins at 130/80, and Stage 2 starts at 140/90. Each stage carries a progressively higher risk of cardiovascular events, stroke, kidney damage, and vision problems.
Roughly 90 to 95 percent of cases have no single identifiable cause. Doctors label this essential hypertension, which can feel like a dead end for patients who want real answers. In practice, these cases involve a combination of arterial stiffness, sympathetic nervous system overactivation, kidney sodium handling issues, insulin resistance, chronic inflammation, and genetic predisposition. Each of those factors is measurable and, in many cases, modifiable.
Lifestyle factors carry more weight than most patients realize. Dietary sodium-potassium balance, physical activity, body composition, alcohol intake, stress management, and sleep quality all influence blood pressure significantly. The DASH diet, regular aerobic exercise, weight management, and stress reduction have each been shown to lower systolic pressure by 5 to 15 mmHg. Those effects rival many medications. Implementing them effectively, however, requires individualized guidance and follow-through, not a pamphlet at checkout.
The conventional approach leans heavily on pharmaceuticals. Medications are often necessary and effective, yet they address the downstream effect (elevated pressure) without investigating the upstream drivers. A patient whose blood pressure is elevated due to insulin resistance, magnesium deficiency, cortisol dysregulation, and untreated sleep apnea will have better long-term outcomes when those factors are identified and addressed alongside medication through functional medicine. Many patients also carry overlapping high cholesterol or thyroid imbalances that influence the readings on the cuff.
