Obesity can bring a variety of metabolic diseases, and some studies have found that weight loss can effectively reduce cardiovascular disease. Many patients with cardiovascular disease can regain their health after weight loss. Why does obesity cause burden to the heart? 1, hypertension When hypertension involves the heart, it will make the heart structure and function change, and the blood pressure will rise for a long time, increasing the burden on the heart and forming hypertensive heart disease. Hypertensive heart disease mostly appears after several years or a dozen years of hypertension. At the beginning, there are no obvious symptoms other than occasional palpitations or shortness of breath. At the onset of the disease, symptoms of left heart failure may appear, with palpitations, shortness of breath, cough, sometimes blood in the sputum, and in severe cases, pulmonary edema. 2, hyperlipidemia Hyperlipidemia can lead to coronary heart disease. When the human body forms atherosclerosis due to long-term hyperlipidemia, the blood flow in the coronary arteries becomes smaller, the lumen of the blood vessels becomes narrower, the amount of blood injected into the heart muscle decreases, resulting in myocardial ischemia, leading to angina pectoris and coronary heart disease. High blood lipid will endanger coronary arteries and form atherosclerosis. A large amount of lipid material protein, deposited and moved in the plasma, reduces blood flow rate, and deposited on the endothelium of arterial blood vessels after acidification through oxidation, and adheres to the wall of blood vessels for a long time, damaging the endothelium of arterial blood vessels and forming vascular sclerosis. 3, sleep apnea syndrome Obesity is a comprehensive disease, and is slowly eating people’s physical health. You need to be correctly aware of the harm of obesity.
