Why should you request this service?

What is the purpose of this analysis?

  • To help you discover the genetic burden of these common multifactorial diseases and allow you to make the link with environmental factors.

  • To show the mechanisms responsible for obesity, diabetes, and cardiovascular disease while providing personalized treatment for each case.

  • To proactively protect yourself and your family from risk.

Should you do it?

  • You have a family history:

    • You have first-degree parents who suffer from obesity or overweight.

    • You have a family history of adult diabetes.

  • You suffer from OBESITY:

    • Severe obesity and / or early origin (childhood / adolescence).

    • You have been on several diets without losing weight or have observed the yo-yo effect.

    • You have eating disorders: satiety or anxiety problems.

    • You can't burn calories despite exercising.

    • You gain weight despite a healthy lifestyle.

  • You suffer from DIABETES:

    • You have difficulty metabolizing carbohydrates.

    • You have high levels of glucose, insulin or glycosylated hemoglobin.

    • Carbohydrates make you gain weight easily.

    • You suffer from obesity (mainly abdominal obesity) and want to prevent the development of diabetes.

  • You want to improve your lifestyle.

additional information

  • What are the genes studied and what does it mean?
      MC4R 155541
      It is related to eating behavior because it reduces satiety and increases appetite, which promotes overweight and obesity OBESITY AND DIABETES : ECONOMIC GENES
      FTO 610966 It reduces satiety and increases appetite for high-calorie foods such as fats and sugars. It also lowers the production of heat of the body, thus promoting the storage of energy in the form of fat
      BDNF 113505
      It reduces satiety and increases appetite for high-calorie foods such as fats and sugars. It also lowers the production of heat of the body, thus promoting the storage of energy in the form of fat
      UCP1 113730 It regulates the action thyroid hormone responsible for burning calories in the form of heat, although at rest this pendant unites physical activity. If this function is slowed down, the body accumulates fat.
      UCP3 602044 It is involved in the production of heat through the thyroid hormone and also plays a role in the burning of calories on physical activity. These are malfunctions that promote overweight and obesity
      ADRB2 109690
      It regulates the response of the body to stress by translating it into a feeling of hunger and responds by storing energy in the form of fat.
      ADRB3 109691 It responds to stress by interpreting it as hunger, which promotes overweight and obesity. It is also associated with insulin resistance and metabolic syndrome. This gene has its effects multiplied in the presence of the gene UCP1.
      PPARG 601487 The ancestral gene is not suitable for contemporary foods such as refined foods (flours and sugars) or processed and saturated fats that promote fat formation and insulin resistance. This gene also complicates the burning of calories. In addition, this gene is the main target of one of the antidiabetic drugs, a good knowledge of this gene allows a personalized treatment
      ACE 106180 This gene regulates blood pressure through the level of sodium in the kidneys and also promotes fat formation, so salt intake not only promotes hypertension, it also causes overweight and obesity.
      IL1B 147720 It promotes chronic inflammation and, associated with the action of the next gene, is directly related to the control of body fat especially in young people. It acts on the regulation of fat formation, the control of intake and energy expenditure and therefore on the impact of obesity.
      IL1RN 147679 It modifies the function of the immune system, promoting inflammation of fat, this being closely related to the development of obesity. Its action is reinforced by that of the previous gene, increasing the amount of total fat.
      IL6 147620 It causes a chronic low-grade inflammation of adipose tissue, induces insulin resistance because it alters its receptor and promotes the development of type 2 diabetes (adult).
      TNFa 191160 It promotes inflammation of the fatty tissue and modifies the insulin receptor and leptitis, causing resistance to these hormones due to the dysfunction of its receptor.
      FABP2 134640 It allows a better absorption of dietary fat in the intestine and alters its oxidation, promoting insulin resistance and increasing the risk of atherosclerosis.
      ADIPOQ 605441 It induces insulin resistance that hinders carbohydrate metabolism and promotes the development of obesity and type 2 diabetes.
      IRS1 147545 It causes insulin resistance and therefore a high risk of diabetes because it directly affects the insulin receptor.
  • How to interpret the results?

      Sixteen genes involved in the causes of obesity and insulin resistance are analyzed. The results obtained can be interpreted as follows: The genes analyzed are distributed in the report according to their pathophysiological processes:

      • GROUP I: Genes involved in the central control of the input
      • GROUP II: Genes associated with the regulation of thermogenesis
      • GROUP III: Genes related to pro-inflammatory processes in adipose tissue
      • GROUP IV: Genes involved in the development of insulin resistance

      The polymorphisms analyzed are variants of normality, so the result of this study should not be considered as a diagnosis, but rather as an indicator of genetic risk.

  • Sensitivity and Specificity

      The analysis of this gene is carried out using the PCR (Polymerase Chain Reaction) technique. Moreover, the results are studied by direct sequencing and subsequent capillary electrophoresis. These molecular biology techniques are commonly used in the field of molecular genetics and exhibit high sensitivity and specificity when using specific primers for each analyzed polymorphism. The reliability of our genetic studies is close to 100%, we apply quality processes certified by competent national and international organizations.
