Antiaging experts point out that this new medical practice will make it possible to identify the genomic particularities that indicate whether a person is susceptible to certain diseases. Genomic medicine is based on the use of genotypic analysis to predict, prevent and treat diseases, revealing the susceptibility of an individual to certain pathologies, caused by certain predisposing genes that interact with environmental triggers. It also allows the diagnosis of these diseases before the onset of symptoms. Among the diseases that can be predicted with this method, some have a high incidence in society such as hypertension, diabetes, obesity, cancer or Parkinson's disease.

This will allow to prevent or delay its appearance avoiding modifiable risk factors, as well as using an individualized treatment (pharmacogenetics) that improves the safety and effectiveness of the drugs.

The genomic term (which defines the study of genes, their functions, and the relationships they maintain with each other and with the environment) emerged at the end of the 1980s, in relation to the Human Genome Project, which was identified by complete the genetic information contained in each cell and written in the language of the DNA.

Knowledge of the genetic variations that exist between individuals also facilitates the choice of the most appropriate therapeutic intervention in each case. This is precisely the goal of pharmacogenetics, which focuses on the development and use of medicines adapted to the genetic characteristics of each individual, so that the precise dose is administered, are more effective, and have fewer side effects.

Although in Spain the life expectancy is higher than the average of the countries of the European Union, which stands at 81.8 years, recent data indicate that Spaniards live with an illness for an average of 25 years, which implies that Spaniards live an average of 55.3 years enjoying good health, while the average community is above, reaching 62.6 years. For this reason, specialists advocate having tools that allow anticipating the emergence of diseases to improve the quality of life of citizens. In this sense, predictive genetic analysis and the use of pharmacogenetics, together with the adoption of healthy lifestyle habits, will contribute to people not only living longer, but also better.
