How Does Lifestyle Play a Role in Genetic Predisposition?

A wise person does today what they will be happy with later on. A foolish person does whatever feels good today and always regrets it later on.

How Your Lifestyle Manipulates Your Genes

Have you ever wondered why you share the same eye and hair color as your father or mother? It's because your genes are passed down from your parents. You will receive half from your mother and a half from your father. You acquire two versions of each gene when you inherit genes from your parents, one from your mother and one from your father. You'll get two versions of genes that include instructions for eye color, for example. Because brown-eye genes are more dominant than blue-eye genes, you will inherit brown eyes if you get blue-eye genes from your mother and brown-eye genes from your father.


Before we talk about genes, we need to talk about cells! All living organisms are made up of cells, which are the essential building components. Your body is made up of billions of human cells, which are too small to view with the naked eye. Your cells collaborate to keep your body running. You have hundreds of distinct types of cells in your body, each with its own set of capabilities. Red blood cells, for example, transport oxygen throughout your body.


Hidden inside almost every cell in your body is a substance called DNA. A gene is a short section of DNA. Your genes are an instruction manual for your body. These instructions include how the body deals with and responds to pathogens, specific foods, pollutants, and other elements of your environment.


How Do Genes Affect Your Health?

Your genes are the manual that tells your body how to function. One to a few nucleotides of DNA in a gene can differ between people. This is referred to as a variation. The term "variant" refers to a gene that has slightly different instructions than the standard form. This can sometimes result in the gene giving cells additional instructions for building a protein, causing the protein to behave differently. Fortunately, the majority of gene variations have little impact on health. However, other mutations alter proteins that perform critical functions in your body, which is how you become ill.


A genetic predisposition (also known as genetic susceptibility) is a higher risk of getting a disease due to a person's genetic composition. Specific genetic differences, which are commonly inherited from a parent, cause a genetic predisposition. These genetic modifications have a role in developing a disease, but they do not cause it directly. Some persons with a predisposing genetic variant will never get the disease even within the same family, while others will.


Although each of these mutations increases a person's risk modestly, having mutations in multiple genes can dramatically raise illness risk. Susceptibility to many common diseases, including cancer, obesity, diabetes, heart disease, and mental illness, could be explained by changes in several genes, each with a minor effect.


Genes, which are made up of DNA, have an essential role in your health, but so do your lifestyle and the factors in your environment.


A variety of factors can influence the risk of disease in people with a genetic predisposition in addition to a known genetic alteration. Other genetic variables (also known as modifiers) and lifestyle and environmental influences are among them. Multifactorial diseases are those that are caused by a mix of causes. Although a person's genetic composition cannot be changed, some lifestyle and environmental changes (such as more frequent illness tests and keeping a healthy weight) may help persons with a hereditary predisposition to the disease.


We've had a heightened understanding of the relevance of genetics in our risk for various diseases and illnesses, both mental and physical since researchers unlocked the human genome some years ago. Research has found links between our genetic profiles and our risk of acquiring health problems ranging from breast cancer and heart attacks to depression, obesity, and Alzheimer's. Some people choose to undergo genetic tests to see if they have copies of specific genes that put them at a higher risk for certain diseases.


However, one bright spot is that, as has become evident in recent years, DNA is just half of the story. As doctors are quick to point out, our lifestyles play a role in increasing or decreasing our risk of different diseases. Our lifestyle choices — the food we put in our bodies, the chemicals we are exposed to, how active we choose to be, and even our social situations — can modify our health at the gene level, according to research in the new subject epigenetics. These decisions can have a significant impact on our disease risk.


How Our Choices Can Affect Our Genes

When scientists discuss your health, they sometimes use the term "environmental variables." This statement can refer to clean air and water and lifestyle decisions such as whether or not you smoke or get enough exercise. Listed below are a few examples:

  • Chronic stress, in particular, has been linked to heart disease, high blood pressure, diabetes, depression, and other health problems. That's why it's critical to discover healthy coping mechanisms, whether it's going for a walk, seeing a therapist, or cutting back on drinking.

  • Cigarette smoking has been linked to more than ten cancers, including lung, kidney, liver, and colon cancers. It's also associated with heart disease, stroke, and other serious illnesses.

  • Obesity has been linked to various health issues, including sleep apnea, type 2 diabetes, stroke, cancer, and osteoarthritis.

Smoking is a well-known example of how our actions can have an impact on our DNA. We all know that smoking harms one's health, but on a molecular level, how does this work? In this situation, carcinogens in cigarette smoke interact directly with molecules in our bodies, causing cancer to spread by altering our anti-cancer genes and rendering them ineffective.


What's been discovered to be equally valid is that the beneficial lifestyle choices we make — including eating well and exercising — may have an equal impact on our genetic makeup. Two recent studies demonstrate this. One study discovered that eating a healthy diet can "switch off" genes linked to a higher risk of heart disease, while another found that exercise can influence stem cells to become bone and blood cells rather than fat cells. Each one reveals how lifestyle factors influence our risk at the genetic level.


It's both alarming and encouraging to realize that our habits have a significant impact on our genes. On the one hand, our genes impact our health since they can put us at risk for things like heart disease, weight gain, and even depression. On the other hand, our habits have a tremendous impact on our health at the gene level. Fruits and vegetables can "switch off" heart attack genes, and exercise can influence stem cell development.


Our genes do not have complete control over us. They are, in many respects, at the mercy of our health and lifestyle choices. Although family history can be a significant predictor of disease, we do have some control over it. Making healthy lifestyle choices isn't always easy, but it can make the difference between having a serious health problem and not having one for many people.
