Healthy Genetics: 5 Health Benefits of DNA Testing
Understanding how your genes work plays a key role in maintaining the health of your
whole body in general. You can know how your body runs and what you can employ to make it stronger. Knowing your gene make-up can also assist you in making decisions that will affect your future. The following are the benefits of having a genetic DNA test done.
1. Disease diagnosis through diagnostic screening
When you undergo a DNA test, specifically diagnostic screening, you get a chance to determine and potentially address some particular genetic conditions based on the given symptoms you may be experiencing. The result may reveal whether you have a given a genetic disease or not. With this information, your doctor can guide you on what steps you can take in order to minimize the effects of the disease.
A good example of this is finding out whether you have a gene mutation associated with Parkinson’s disease or establish whether you have markers such as BRCA1 and BRCA2 that are known for breast cancer. On the other hand, if the results are negative and you do not have a specific genetic condition, you will have peace of mind.
2. Prenatal testing benefits & newborn screening
If you want to have children in the future, knowing specific details of your health in terms of genetic mutations is very important. If the results are positive on mutations, this means you can potentially pass on diseases to your kids. As a result, you may opt on not having them, devise ways of minimizing the chances of the disease, or at least be better prepared.
Newborn babies also benefit significantly from being subjected to genetic testing. With newborn screening, you can establish disorders that can be treated as early as during birth. For instance, with saliva from the father and blood from the mother, you can establish whether the fetus poses chromosomal abnormalities. If the disease cannot be treated, the parents will have comfort in the fact that they can accept the results, prepare, and find out ways to take care of the child.
3. Assist in weight loss & sleep
Some research studies have proven that weight chances are attributed to some genes in the human body with approximately 80 percent of body fat controlled by genes. Knowing about the genes related to weight can allow you to compose a diet and routine that will render the activities of the genes to the lower end of the spectrum.
Genes are also tasked with regulating your sleep. They do this by controlling your circadian rhythm, which are physical, mental, and behavioural changes that occur depending on the presence of darkness or light. For example, if you have a specific mutation, you may get tired earlier compared to other people. Knowing this, you can employ mechanisms that regulate your melatonin production that will result in a sleep-wake cycle best suited to your routine.
4. Identifying enzyme deficiencies and mutations
Having a DNA test completed can help establish mutations responsible for enzyme deficiencies. For instance, the MTHFR enzyme is responsible for biochemical reactions within the body such as B12 assimilation and controlling detoxification pathways. The inadequacy of this enzyme leads to serious issues in your body such as lupus, anemia, and cancer.
5. Determine carriers & digestion problems
With DNA testing, gene mutations of two partners can be determined. The disorders that a child may experience due to these genes can then be confirmed.
Once established, health issues can be avoided with the help of a doctor. For example, having a genetic test will reveal how well your stomach digests gluten and dairy products. Having this information in advance will save allow you avoid unfavourable symptoms of intolerance such as cramps, vomiting, constipation, diarrhea, and bloating.
