When the darkness is detected in the back of the neck, this is a sign that a pre-diabetes test is performed, explained Dr. Rubén Silva, specialist in internal medicine and endocrinology, during the XXXI National Diabetes Congress, recently held in Acapulco, State of Guerrero, Mexico
The clinical name of this condition is acanthosis nigricans and is an "alarm signal", meaning that pancreas has anomalies, said Silva.
In pre-diabetic conditions there is insulin resistance, and this phenomenon means that the pancreas produces an excessive amount of insulin and is reflected on the level of the skin, "said the expert.
In the meantime, prediabetes is a suitable diagnosis of factors indicating that a person has a high risk of developing diabetes, but it is still in time to prevent or delay occurrence at an early age.
"To have a pre-diabetic, we need to have a high glucose level, but not so much as to fall in the diabetes criterion," said an expert who added that people often ignore several risk factors.
People with a glucose concentration between 100 and 125 mg / dl have a risk of developing between 6% and 9% of developing diabetes between the next year and between 140 and 199 mg / dl between 5% and 10%, explained Silva.
Due to such measurements, Silva recommends that direct relatives of people with diabetes are the first to perform a pre-diabetes test and change their lifestyle.
According to the National Health Survey in Mexico, diabetes is more prevalent in women (10.3%) than men (8.4%). This trend is evident in urban areas (10.5% in women and 8.2% in men) and in rural areas (9.5% in women, 8.9% in men).
"Diabetes is a burden for the family and the patient, creating costs, consulting and adjusting family dynamics, including for the health system and affecting the personal environment. We can prevent this dynamism, "Silva said.
One of the tests with which prediabetes can be known is the "Finnish Diabetes Risk Assessment," where points are assessed by age, body mass index and bandwidth, physical activity, type of blood pressure, genetic inheritance and glucose level.
Diagnosis should also include laboratory studies for the measurement of cholesterol, triglycerides and uric acid.
