We have spoken many times that the overweight predisposes to diabetes type II, but what is this disease?
The diabetes1 is a disease in which levels of glucose (sugar) in the blood are above normal values because diabetics have difficulty in converting the sugar into energy.
After a meal it would be normal to break down food into glucose, which is transported by the blood throughout the body, then, cells of different parts of our body uses a hormone called insulin (produced in the pancreas) to convert the glucose in the blood into energy.
What happens in people with diabetes is the lack of insulin (diabetes type I) or not used in the appropriate manner, the pancreas can not produce enough insulin to placate the needs of the body, so glucose is not changing and each After more of this molecule in blood.
The problem is not there, not just about our bodies receive less energy you need, or that our blood sugar is more normal, but these high levels of glucose have on the rest of our body: damaged blood vessels and nerves which causes for example that the risk in our legs is poor and therefore of the foot diabético2, blindness, because the circulation in the capillaries of our eyes is poor, the lower gums, heart disease, stroke.
All these problems, and what it represents for our quality of life, suddenly we have to keep a tight control of our exercise, our diet and our emotions or we can fall into episodes of hypoglycemia and hyperglycaemia. Why are we interested in this, particularly for people with overweight or obese? Because both are closely related, obese people have a much higher risk of having type II diabetes.
In the study of which we speak involving 3234 people at high risk of diabetes, all of whom were overweight, and blood glucose levels higher than normal (called prediabetes), and to group all fronts within them chose to individuals of different races, women who had gestational diabetes and people older than 60 years (risk groups).
In 3000 these people were divided into 2 groups: one of them discussed the relationship of a drug (metformin) with reduced risk of diabetes and the other a lifestyle change in relation to that risk reduction.
The lifestyle change was essentially a few 30 minutes of exercise a day for 5 days a week (usually walking), and a healthy meal, plus a weight loss (average 6.8 kilos), and only with that in a year lowered their risk of diabetes by 58%, while those who took the drug only reduced by 31%, which shows that to prevent the onset of diabetes is much more effective a change in our lifestyle drugs.
And you can not say more, all data are on the table, lose weight and walking several days a week can reduce by more than 50% your risk of diabetes, and thus avoid all the complications that you can make with time: blindness, foot injuries, amputations.
