How Does Obesity Affect Heart Disease?
The obesity increases the risk of infarct and cerebrovascular accident. The Cardiovascular risk increase begins from BMI= 27 kg/m². Then, how does obesity affect heart disease?
According to the World Health Organization, every year, 2.6 million people at least die from consequences of the overweight and the obesity.
Toxic metabolic disorders for the heart
The obesity comes along frequently with arterial hypertension, with increase of the blood lipids rate (hyperlipidemia) and with diabetes (type II, non-insulin-dependent). On the other hand, it promote the reduction of the HDL (the good cholesterol).
These metabolic anomalies lead to the formation of atheroma. So, This atheroma will block the arteries of the heart and the brain.
Various cardiovascular diseases
The deposit of fatty plaque along arteries increase the risk of pectoris angina or myocardial infarction. It also leads to ischemic phenomena (blood flow decrease), which can achieve a necrosis of the not irrigated zones.
A more important concentration of fat in the blood leads to the deposits, which slow down the blood circulation. It can be source of pain or of problems. The most frequent are the varicose veins, the phlebitis, the edemas and the heavy legs.
The obesity in itself can promote the appearance of the heart rhythm disorders (atrial fibrillation). these disorders entail the cerebrovascular accident.
The android obesity, where the fat is especially localized at the belly, presents more the cardiac complications than the gynoid obesity. It can be at the origin of an arterial hypertension, of an insufficiency cardiac or of a cardiovascular accidents.
The obesity thus represents a serious danger, beyond diverse diseases and limitations. It can also mean a life expectancy reduction. This information was confirmed in numerous studies which indicated the importance of the prevention and the necessity of an adequate treatment for the obesity.
