Key result
Obesity contributes to hypertension through various mechanisms including sympathetic nervous system stimulation, and weight loss is essential for effective blood pressure control.
Why the study?
Obesity is an increasing public health problem that causes mortality and leads to comorbidities such as hypertension.
This review outlines the mechanisms of obesity-induced hypertension and highlights the importance of weight loss and metabolically favorable antihypertensive drugs like ACE inhibitors and ARBs.

Sympathetic mechanisms in obesity-hypertension remain hypothesis-generating; prospective trials needed before targeting alters practice.
Obesity is an important public health problem with increasing frequency, leading to different comorbidities including hypertension and can cause mortality. Possible mechanisms that increase blood pressure in overweight and obese people are renal damage, activation of the renin-angiotensin-aldosterone system, insulin resistance, hyperinsulinemia, sleep apnea syndrome, leptin-melanocortin pathway and genetic predisposition. Most of these mechanisms stimulate the sympathetic nervous system. Medical nutrition therapy, lifestyle interventions, medical and/or surgical antiobesity treatment modalities contribute to the control of blood pressure via weight loss. Besides antihypertensive medications should be chosen carefully in overweight and obese patients and drug groups preventing weight loss should not be preferred if possible.
