First of all, obesity increases the heart load and is prone to heart failure for the following reasons: 1. The total amount of blood increases. Obese people store too much fat in the body, the basal metabolic rate increases, in order to adapt to this state, the heart will correspondingly increase the force of contraction, when the heart is overwhelmed, it can no longer effectively pump blood, resulting in the accumulation of blood in the cardiovascular system, and in heavy cases, heart failure. 2, the heart muscle contraction ability decreases. Obese people often have atherosclerosis and myocardial fat accumulation, ventricular muscle compensatory hypertrophy, and the elasticity of the hypertrophied myocardium decreases, and the heart itself gets insufficient blood supply, resulting in a further decline in heart function. 3, combined with other diseases. Compared with people of normal weight, obese people are more likely to hypertension, diabetes, hyperlipidemia, sleep apnea, hyperuricemia, etc., and these diseases are important risk factors leading to cardiovascular disease. They are “wolf for wolf”, mutual influence, aggravate the body inflammatory response, prompting the occurrence and progress of cardiovascular disease. For this reason, obese people must keep their weight within the normal range (BMI 18-24). Mainly through: diet control and exercise exercise, scientific weight reduction. Add weight loss medication if necessary (must be taken under professional medical supervision). Also treat the coexisting hypertension, diabetes and hyperlipidemia. Only with comprehensive treatment can we have a healthy and strong heart.
