Overweight is the result of either improper nutrition or a sedentary lifestyle, or a mixture of the first and second. In the diet of a person with a similar problem prevails carbohydrate and fatty foods. As is known, carbohydrates and fats have the highest energy value, that is, they are more calories than proteins. The latter pose no threat to humans, but rather they are the building blocks perform enzyme and many other functions in the human body. That is why many of the diets lies in a protein diet. So what threat overweight?
An increased amount of fat in the human diet leads to the fact that the liver does not have time to recycle them, and increases blood levels of low-density lipoproteins. They tend to be deposited on the walls of blood vessels and, over time, gradually clogging them. As a consequence, the lumen of vessels narrows and the blood more difficult passes through the vessels, i.e. there is increased vascular resistance, leading to hypertension. High blood pressure is the cause of the rapid “wear” blood vessels, kidneys, and myocardium of the heart. Hypertension triggers a cascade of responses in the body, which are closed in a vicious circle.
For example, hypertension leads to wear of the myocardium, which in turn leads to heart disease, So the heart loses its ability to adequately krovosnabzhenie peripheral organs due to the fact that since less force is pushing blood through the systemic circulation. There is a state of hypoxia when the organs is not enough oxygen, which should bring him to the arterial blood. Most acutely at the state of the hypoxia-responsive brain and kidneys. The kidneys secrete the enzyme angiotensin 1, which in the lungs is converted to angiotensin 2, which contributes to even more constriction of blood vessels in order that blood better come to the kidneys, which further aggravates the condition of hypertension. But besides that the heart loses its ability to adequately krovosnabzhenie peripheral organs, it gradually loses the ability to krovosnabzhenie itself. This phenomenon is called angina, which is characterized by sharp pain behind the breastbone during physical exertion or even at rest. For the brain, high blood pressure threatens the risk of stroke. But it’s just not a complete list of possible consequences.
As mentioned above, in the blood stream increases the amount of low-density lipoproteins. And in addition to the above chain of pathological processes, their effect may be another, no less dangerous. Putting off walls of blood vessels, they can contribute to the disruption of the interaction of insulin with insulin receptors of peripheral tissues, in other words, occurrence of diabetes mellitus type 2.
The high content of fat can lead to fatty infiltration of the liver. The liver cells are replaced by fat cells — adipocytes, and the liver gradually loses its ability to perform its functions. It is primarily a synthesis of the essential proteins in our body, for example, blood clotting factors, resulting in increased bleeding. The liver performs detoxification function, for example, when the neutralization of alcohol or any drug, which is also gradually being lost.
All of the above consequences of obesity can occur separately and comprehensively. This phenomenon is called metabolic syndrome. Developed a range of measures to protect the human body from such phenomena. To do this, eat right, exercise, control your blood pressure, stop Smoking. If you are obese, the main rule is the application of preventive measures in combination with modern drugs that lower blood pressure and lower levels of low-density lipoproteins.
