What is Genomics?
Genomics is the study of a person's entire genetic material, including all of its genes and their interactions. Genes are like a set of instructions that tell your body what to do and how to do it. Think of your genes as a recipe book for your body. Just like how a recipe tells you how to cook a dish, your genes tell your body how to function and grow.
Pharmacogenomics
Pharmacogenomics is the study of how genes affect a person's response to drugs. It helps us personalize treatment plans based on a patient's genetic makeup. For example, some people metabolize medication quickly, while others may metabolize it slowly. We can use this information to adjust the dosage or choose a different medication to avoid side effects or improve the effectiveness of the treatment.
​
An example of how pharmacogenomics can be used is in the treatment of depression. There are many different types of antidepressants available, and they work differently for different people. By using a patient's genetic information, doctors can choose a medication that is more likely to work for them and avoid medications that may cause adverse side effects.
Nutrigenomics
Nutrigenomics is the study of how genes interact with nutrients in food. It helps us understand how food affects our health and how we can personalize our diets based on our genetic makeup. Think of nutrigenomics like a personalized nutrition plan that is tailored to your unique genetic makeup.
​
An example of how nutrigenomics can be used is in the prevention of heart disease. Studies have shown that people with a certain genetic variation may have a higher risk of developing heart disease. By using this information, doctors can recommend specific dietary changes, such as reducing saturated fat and increasing intake of omega-3 fatty acids, to reduce the risk of heart disease in people with this genetic variation.
