Chronic diseases mainly refer to a group of diseases represented by cardiovascular and cerebrovascular diseases (hypertension, coronary heart disease, stroke, etc.), diabetes mellitus, malignant tumors, chronic obstructive pulmonary diseases (chronic bronchitis, emphysema, etc.), mental anomalies and mental illnesses, etc., which are characterized by a long course of disease, complex etiology, and serious health damage and social hazards. The harm of chronic diseases is mainly caused by the brain, heart, kidney and other important organs of the damage, easy to cause disability, affecting the ability to work and quality of life, and the medical cost is extremely expensive, increasing the economic burden of the community and the family. Obesity can cause nearly half of the chronic diseases. So the question is, is obesity a chronic disease? This varies from person to person, can not be reduced is a chronic disease. But that being said, those who can lose weight have lost it long ago. Obesity can cause a variety of problems: First of all, the most direct effect of the increase in total body weight is the damage to the weight-bearing joints. Exercise to lose weight may damage the joints, do not lose weight can only silently keep on. Next is a variety of chronic diseases ensue, the “three highs”, coronary heart disease, diabetes, fatty liver, endocrine impact. Let’s take diabetes as an example, diabetes will destroy the body’s functions, due to the compensatory function of various organs (demolition of the east wall to make up for the west wall) to maintain the normal function of the body. And when the disease appears: three more and one less (more drinking, more urination, more food and weight loss). Weight is lost, but the pancreas has received irreversible damage. The only way to stabilize the condition is to take medication or even inject insulin for a long time. Therefore, we urge everyone to lose weight quickly, do not let obesity become a “chronic disease”. A lot of damage is irreversible, do not wait until the parts are broken and then regret.
