Obesity and Heart Problems: A Review

Abstract

Excess body weight puts severe strain on the heart and blood vessels, significantly increasing the risk of cardiovascular disease. [1, 2] How Obesity Affects the Heart • High Blood Pressure (Hypertension): Extra body fat increases resistance in blood vessels, forcing the heart to pump harder. [1] • High Cholesterol: Obesity raises "bad" LDL cholesterol and triglycerides while lowering "good" HDL cholesterol, leading to fatty plaque buildup in the arteries (atherosclerosis). [1, 2] • Type 2 Diabetes: Excess weight drives insulin resistance, which accelerates damage to blood vessels and heart tissue. [1] • Chronic Inflammation: Adipose (fat) tissue—especially around the abdomen—releases pro-inflammatory chemicals that harm arteries and promote clotting. [1, 2] • Direct Heart Muscle Damage: Excess weight can independently cause heart muscle enlargement (left ventricular hypertrophy) and heart failure, even without high blood pressure or diabetes. [1, 2] • Sleep Apnea: Obstructive sleep apnea is common with obesity and strains the heart, raising the risk of arrhythmias and pulmonary blood pressure Key Heart Complications • Heart Attack: Caused by blocked or restricted blood flow in coronary arteries. [1] • Heart Failure: The heart struggles to pump enough blood to meet the body's needs. [1, 2] • Stroke: Blocked or damaged blood vessels leading to the brain. [1, 2] • Arrhythmias: Irregular heartbeats caused by structural changes in the heart chambers. [1] Prevention and Management • Weight Reduction: Gradual weight loss through a balanced diet and regular physical activity reduces heart strain and lowers inflammatory markers. • Regular Screening: Monitor blood pressure, blood sugar, and cholesterol levels. • Medical Guidance: Consult healthcare providers or cardiologists for tailored lifestyle plans, medical therapies, or weight-management interventions.
