Does obesity alone cause hypertension?
Does Obesity Alone Cause Hypertension? Obesity does not cause hypertension, although it can contribute to it. Other factors can increase your risk of high blood pressure, such as kidney problems, thyroid conditions, obstructive sleep apnea, and a family history of hypertension.
How does obesity cause hypertension physiology?
The mechanisms through which obesity causes hypertension are complex and include sympathetic nervous system overactivation, stimulation of the renin-angiotensin-aldosterone system, alterations in adipose-derived cytokines, insulin resistance, and structural and functional renal changes.
Do obese people all have high blood pressure?
Objective: The link between obesity and elevated blood pressure is firmly established. However, not all obese individuals are hypertensive, suggesting that adaptive mechanisms are present in at least some obese individuals which allow them to maintain normal levels of blood pressure (BP).
How does fat affect blood pressure?
Abstract—Dietary fat contributes to the elevation of blood pressure and increases the risk of stroke and coronary artery disease. Previous observations have shown that voltage-gated Ca2+ current density is significantly increased in hypertension and can be affected by free fatty acids (FAs).
Why does obesity cause high cholesterol?

What causes high blood pressure?
- A diet high in salt, fat, and/or cholesterol.
- Chronic conditions such as kidney and hormone problems, diabetes, and high cholesterol.
- Family history, especially if your parents or other close relatives have high blood pressure.
- Lack of physical activity.
Does belly fat cause high blood pressure?
Waist circumference is a measure of excess fat around the waist and is an important measure for obesity. Excess belly fat has been linked to increased risk for diabetes, heart disease and high blood pressure.
How does visceral fat cause hypertension?
Second, visceral fat contributes free-fatty acids through the portal vein, which may lead to insulin resistance which was shown to be associated with the prevalence and incidence of hypertension [39,40,41].
Does losing body fat reduce cholesterol?
If you are obese and have high cholesterol, losing weight should help lower your cholesterol, as well as your risk for other obesity-related conditions including diabetes and cardiovascular disease.
