Metabolic syndrome (MetS) is a health disorder, untreated, can greatly increase the risk of several chronic diseases. You may not have heard of it and yet you may be a victim of it without your knowledge. It is not cardiopathy, diabetes, or obesity, although these three conditions are associated with it.
Doctors are just beginning to recognize it: we are facing a major health crisis.
Today everyone should be concerned about his blood sugar. Not just a few people.
«Suspected since the 1930s from clinical observations in diabetic patients and then
approached in the 1960s with the development of the radioimmunoassay for insulin, the presence of
insulin resistance has been confirmed over the past 20 years by different methods of evaluation more or
less performing. Initially objectified in the obese and / or diabetic type 2, the decrease in insulin
sensitivity can in fact affect a much larger population. The concept of insulin sensitivity became very
important when Reaven in 1988 drew attention to the role of insulin resistance in different pathologies.
Thus was born the notion of metabolic syndrome or syndrome X was characterized by the association of
various cardiovascular risk factors (including reduced glucose tolerance, hypertension and dyslipidemias),
all related to insulin resistance that is the foundation of the syndrome. Although the signaling pathway
for insulin appears to be particularly complex and the determinism of insulin resistance still largely
unknown, it is important to develop strategies, pharmacological or not, to improve insulin sensitivity
in the event of resistance to the action of the hormone. This approach should not only ensure better
glycemic control in the case of type 2 diabetes, but also improve the cardiovascular prognosis of more
and more patients, both diabetic and non-diabetic, with metabolic syndrome. »
« Insulin resistance has become, in a few years, an essential concept in medicine. Although its determinism is still imperfectly known, the decrease in insulin sensitivity is clearly associated with major pathologies and, at least partially, determines the prognosis. These, like obesity, type 2 diabetes or high blood pressure, are diseases largely related to the lifestyle of modern society favoring sedentary lifestyle and food drift. Their prevalence is also increasing in all the industrialized countries so that the World Health Organization does not hesitate to speak of a veritable "epidemic". »
Our unbridled taste for foods that raise blood glucose levels has resulted in a real epidemic of
insulin resistance, which can be defined as an inability of the body to manage glycemic peaks when demand
is too high or over a long period of time. It is like playing the yoyo with your blood sugar and there are
unfortunately consequences on all the human body, your organs, your arteries, your heart and your waist.
Insulin resistance is associated with various serious problems ranging from heart disease to memory loss through diabetes (type 1 and type 2) and especially "silent diabetes", as everyone knows when a disease hatched in broad daylight is that it has already wreaked inside before, so you might actually already suffer from it.
The number of people with diabetes has increased dramatically in recent years. Deaths related to this disease reached 1.5 million in 2012 and the World Health Organization estimates that diabetes will become the 7th leading cause of death worldwide in 2030.
Diabetics can live for several years without being aware of their hyperglycemia (excessive sugar level, ie greater than 126 milligrams per decilitre of blood, on an empty stomach). However, the complications of diabetes can be cumbersome: cardiac infarction, stroke, blindness, renal insufficiency...
By a simple blood test, by controlling the level of blood sugar.
Otherwise diabetes is often found when people live with chronic complications. Kidney problems, leg sensitivity disorders, heart attacks ... These people have had diabetes for several years, and their disorders might have been prevented if the disease had been well controlled.
Screening for diabetes before the onset of symptoms is the only effective way before suffering the serious consequences of diabetes.
It is recommended that people over 45 years of age, or at any age with risk factors:
Fortunately, the course of insulin resistance can be reversed, because if eating badly provokes it, eating well can cure it. In addition it is quite easy.
Indeed, damage does not occur instantaneously; even modest changes in your diet can put you back on the path to the Health and allow you to feel more alert, more alive and more energetic.
When you need a little backup, what do you take? A sweet bar, crackers, raisins, ...? These fast foods dissolve quickly in your stomach and in no time are found in your bloodstream, flooding your body with glucose, and you are ready to start on a quarter turn. The problem is that this influx does not last.
When you have reached the end of your energy, you are hungry again; In fact you are literally hungry! And the cycle begins again ... until the dinner where you will engulf a hearty meal to ward off this great hunger.
In most cases, the body can bring back to normal a blood sugar that has risen excessively after a large meal. It remains permanently elevated only in diabetics who are not treated. This is why doctors have long thought that only diabetics had to worry about the effects of their diet on their blood sugar.
Today, we know that a rise in blood glucose following a meal can eventually damage the body of healthy people, even if it never causes diabetes.
In short, blood glucose is no longer the concern of a few people; We all have reason to care, even if we are thin and healthy, but especially if we do little exercise and if our size gets rounded by excess weight.
Choosing the right foods, of course. And by not eating less but better. Avoid draconian diets, they bring absolutely nothing to the body and do more harm than good.
In principle, eating should calm hunger, is it not? Well, it depends.
When you eat, especially starches and sugars, foods are converted to glucose, the main fuel of your muscles or brain. It's instant energy!
But a meal rich in starchy foods can bring the body more glucose than it needs. In fact, it can raise blood glucose levels twice as much as a healthier meal.
Most of the time, blood glucose returns to normal one or two hours after the meal with insulin, a hormone secreted by the beta cells of the pancreas. Insulin sends to the body the signal that it must let glucose enter the cells so that they can use it as fuel, and that it must store the rest in the muscles.
But if, for example, you eat a large portion of fry with a slice of bread, your body suddenly faces a significant intake of glucose; it reacts by secreting enormous amounts of insulin. If you are overweight, it could secrete more.
All of this excess insulin lowers your blood sugar considerably and keeps it down as long as it continues to act, sometimes for long hours. Result: you fall from starvation (Dying of hunger), as if you had not eaten anything for ages.
Normal, because your body responds to this low blood sugar by secreting hormones that raise blood sugars and fat levels (the same ones that could cause a heart attack). Your brain sends you a signal that you are hungry, even if you have absorbed more calories than needed.
The hunger signal is caused not only by low blood sugar, but also by rapidly falling blood sugar levels.
A balanced meal boosts the rate of leptin, a hormone that calms the feeling of hunger, and lowers the rate of ghrelin, a hormone that stimulates hunger.
Studies have shown that people who had a fast carbohydrate-rich breakfast or dinner consumed 500 more calories in the next 5 hours than those who had a more balanced diet.
In other studies, the differences were less pronounced, but we still talk about 150 more calories.
Even 100 more calories a day make all the difference between gaining weight and losing it and have an impact on your overall health.
In addition to producing more insulin after a hearty meal, which increases blood glucose levels, the body stops burning fat because it needs to use all of that extra glucose first. Result: your waist increases. Now, this fat on your abdomen harms your health.
By avoiding marked fluctuations in blood sugar, you will have less difficulty losing this excess fat.
A diet that undermines blood sugar increases the risk of a heart attack: arterial obstruction, hypertension and inflammation.
Hyperglycemia produces unstable forms of oxygen called free radicals; these molecules damage the arteries, affecting blood pressure and favoring the formation of cholesterol deposits on the walls of the arteries.
The extra insulin that the body must produce to control blood sugar also has consequences: elevated blood pressure, formation of dangerous blood clots and inflammation. All of this helps increase your risk of heart disease.
In the long run, the consumption of foods that trigger a strong glycemic response also leads to lower HDL ("good") cholesterol levels and an increase in triglyceride levels (fats that are toxic to cells), which further increases the risk of heart disease and cardiac arrest.
Fortunately, the opposite is true: the more your diet saves your blood sugar, the more it will also spare your heart. Various studies have found that in people whose diet had the least fluctuation in blood glucose, HDL (good) cholesterol was high, triglycerides were low, and heart attacks were null.
You will no longer look at your fries and your bread hamburger in the same way at your next "fast food"!
The good news is that family doctors can diagnose the metabolic syndrome and treat with an exercise program and healthy diet that has been proven.
