What is a gene?

Every human being is made up of billions of small cells and the cells come together to form the tissue of our body. Each cell contains a cell nucleus; within this cell nucleus, there are approximately 30’000 different genes that govern the various features and mechanisms of our bodies. For example, some genes determine the color of our eyes, some determine the length of our length, some are responsible for the digestion of food, while others assume the functions of nerve cells in our brains. All these genes come together to form the structure plan of our original body.

Structure plan of our body

Unfortunately, not all of our genes are perfect; in all of us, either passed from our parents to us or formed in some way; There are some gene defects that adversely affect our health. These gene defects can, for example, weaken our immune system, increase our risk of heart attacks, or cause distorted eyes. They can cause asthma and allergies, and when we eat irregularly, we can gain weight immediately. Of course, because one of us does not match the gene defect, the risk of heart attack in one person is high, while the risk of lactose intolerance in another may be high. The frequent occurrence of certain diseases in some families is one of the important data showing that the risks of the disease can vary from family to family and from person to person.

Genetic defect and increased risk

Gene defects can affect our health, but in many cases they are not definitive evidence that the disease will occur. Genetic defects should only be considered as an increased risk of disease. Whether or not the disease occurs depends on external factors such as the environment and lifestyle. For example, if a person is hypersensitive to lactose due to a gene defect, that person is extremely healthy as long as he does not drink milk. If signs of intolerance occur while not drinking milk, this is an effect caused by environmental factors, such as the lactose content of the foods consumed.

The same applies to other diseases. For example, if there is a defect in a gene that balances iron absorption, it increases the risk of iron absorption disorder; In this case, it is necessary to take precautions against absorption disorder and even to adopt a lifestyle that will prevent this disorder completely.
