Both hypertension and diabetes sneak up on their victims, often doing damage before people even know they have the disease. Genetic screening could prevent that. New and better treatments derived from genetics could focus on the underlying molecular causes of the disease, rather than on the symptoms. Medication could be tailored to the individual based on her genetic makeup. Presently, the dozens of medications available for hypertension, for example, vary in their effectiveness from person to person.
Genetic differences are the suspected cause.
Such efficient prescribing of medications would also save time, money, and avoid side effects while improving treatment.
