Genetic obesity testing: Your guide to understanding the causes of weight gain and choosing the right care
Many people struggle with weight gain despite their continuous efforts to follow diets and exercise. Some may succeed in losing weight easily, while others find it very difficult to achieve the same results. This is due to a range of health, behavioral, and environmental factors, and genetic factors may also be a contributing factor in some cases.
Genetic obesity testing helps identify genetic variations related to appetite regulation, satiety, energy expenditure, and fat storage. It provides valuable information that helps physicians and genetic counselors understand the condition more accurately, especially in cases of severe obesity that appeared at an early age or with a strong family history.
Enigma Genomics offers genetic obesity testing that includes analyzing 65 genes associated with obesity, with the aim of helping to discover potential genetic causes and take appropriate health steps based on expert assessment.
What is genetic obesity?
Genetic obesity is a severe weight gain associated with changes in one or more genes responsible for regulating appetite, satiety, energy expenditure, and metabolic processes within the body.
There are rare cases resulting from a change in a single gene, known as monogenic obesity. These may begin in early childhood and are accompanied by a severe and persistent feeling of hunger and difficulty controlling food intake.
Most cases of obesity result from a more complex interaction between several genes and other factors such as diet, lack of exercise, sleep disorders, psychological state, and certain diseases and medications. Therefore, a genetic predisposition does not mean that obesity is inevitable.
How do genes affect body weight?
Genes contain the instructions that help the body's cells perform their functions, and some genetic changes can affect the signals exchanged between the brain, the digestive system, and fat tissue.
These signals help determine when you feel hungry, when you feel full, how much energy your body uses, and how it stores fat. An influential genetic change may lead to a diminished sense of satiety, increased food cravings, or decreased energy expenditure.
Genetics does not operate independently of lifestyle; two people may have similar genetic predispositions but differ in weight due to differences in physical activity, diet, sleep, and health status.
What is genetic obesity testing?
Genetic obesity testing is an analysis that examines a number of genes associated with obesity in order to look for variations that may explain severe or premature weight gain.
The examination is performed using a suitable sample such as blood or saliva, according to laboratory instructions. DNA is then extracted and the targeted genes are analyzed. Afterward, specialists review the detected changes and assess their correlation with the health condition, symptoms, and family history.
Enigma's genetic obesity screening includes the analysis of 65 genes associated with obesity, providing a specialized assessment for cases where a genetic cause is suspected.
Who needs genetic obesity testing?
Not everyone who is overweight needs genetic testing; therefore, the case should first be assessed by a doctor or genetic counselor.
Genetic obesity testing may be appropriate if severe obesity develops before the age of five, or if there is excessive and persistent hunger or rapid and unusual weight gain during childhood.
It may also be recommended when more than one family member suffers from severe obesity, or when other symptoms appear such as delayed growth, delayed motor and mental development, hormonal disorders, vision and hearing problems, or the presence of congenital malformations.
Early childhood obesity
The appearance of severe obesity in the early years of a child's life is one of the most important signs that needs careful evaluation, especially when weight gain is disproportionate to eating habits or accompanied by extreme hunger.
The results of genetic obesity screening may help determine if a child carries a gene variant that affects appetite, satiety, and energy pathways, and early diagnosis can guide the family toward appropriate follow-up and reduce the risk of future complications.
The child should be treated in a supportive manner, avoiding blame, because difficulty controlling food may be related to biological mechanisms beyond their control.
The role of family history
Family health history is an important part of assessing genetic obesity; therefore, a genetic counselor will ask about the ages of family members when they began gaining weight, their degree of obesity, and the presence of co-existing conditions such as diabetes, high blood pressure, and heart disease.
The more severe obesity appears in more than one individual and at similar ages, the more important it becomes to investigate the possibility of a shared genetic factor.
However, the presence of obesity within a family does not alone prove the existence of a specific genetic change, as family members often also share dietary habits, activity levels, and environment.
What does the Enigma genetics test include?
The genetic obesity test offered by Enigma Genomics is based on the analysis of 65 genes associated with weight gain and obesity.
These genes are linked to multiple functions including appetite control, satiety, communication between the brain and fat tissue, energy regulation, and certain hormonal and metabolic processes.
Analyzing a wide range of genes helps increase the chance of finding a genetic explanation when a known and significant variant is present. However, testing does not guarantee discovering a genetic cause in all cases because scientific knowledge is still evolving, and there may be variants in genes whose relationship to obesity has not yet been established.
How is the examination performed?
The journey of genetic obesity screening begins with gathering health, personal, and family information, then the specialist determines the suitability of the screening for the individual case.
The required sample is then collected according to Enigma's guidelines for genetic medicine, and the collection and preservation method must be strictly followed to ensure sample quality.
The sample is sent to the laboratory for DNA extraction and gene analysis. The results then undergo stages of scientific review and interpretation. After the report is issued, genetic counseling helps explain the result and what it means for the individual and their family.
What might the result show?
Genetic obesity testing may reveal a pathogenic or potentially disease-causing gene variant, meaning there is scientific evidence linking the variant to the condition.
The analysis may reveal a change of unclear significance, meaning there is insufficient information to determine its impact, and this result alone should not be used to make a treatment decision.
The result may also be negative, meaning that the test did not detect a known change within the analyzed genes. A negative result does not mean that genetic factors are completely absent.
The importance of genetic counseling
The benefit of genetic obesity testing is not complete simply by receiving the report, because interpreting the results requires a specialist who can link genetic changes to symptoms, health history, and family history.
Genetic counseling before testing helps in understanding its benefits, limitations, and potential outcomes, and after testing it helps in explaining the meaning of the result and whether other family members may need evaluation or analysis.
Enigma Genomics offers genetic counseling services to help individuals and their families understand the report and avoid misinterpretations or decisions based on incomplete information.
Benefits of early diagnosis
Early diagnosis of the genetic cause can help reduce the time a family spends between multiple tests and attempts without reaching a clear explanation.
Diagnosis may allow the doctor to determine the appropriate follow-up care and to look early for potential complications such as blood sugar imbalances, high blood pressure, fatty liver disease, and blood lipid disorders.
The diagnosis also gives the family a better understanding of the condition and helps them provide appropriate psychological and nutritional support, rather than considering weight gain solely as a result of weak willpower.
Does the examination determine the appropriate diet?
Genetic obesity testing does not provide a ready-made diet plan, and its results alone cannot be relied upon to choose a diet or medication.
Genetic information helps in understanding some of the causes of obesity, but a health plan also needs to assess weight, height, age, activity level, hormonal status, co-existing diseases, and dietary habits.
A weight management plan should be developed in collaboration with a doctor and a nutritionist and may include improving food quality, regulating portion sizes, increasing physical activity, treating sleep disorders, providing psychological support, and using medication when needed.
Does a positive result mean that obesity is inevitable?
A positive result does not mean that the person will not be able to control their weight or improve their health, but rather that they have a genetic factor that needs to be understood and properly monitored.
The severity of the impact of genetic change may vary from person to person, and the final outcome is also influenced by lifestyle, age, hormones, psychological state, and other factors.
The value of genetic obesity testing lies in transforming uncertainty into information that helps in making more realistic decisions and setting appropriate health goals for the individual, rather than following general plans that may not take into account the person's needs.
The relationship between genetic obesity and mental health
People with obesity may be subjected to bullying, blame, and social stigma, which can affect their self-confidence and mental health. These problems may be more severe in children and adolescents.
Discovering the genetic cause helps change the family's understanding of the condition and confirms that obesity is a complex disease that cannot be reduced to overeating or lack of willpower.
However, the result should not lead to despair but should be used to build a supportive plan that combines medical care, healthy nutrition, appropriate activity, and psychological support.
Preventing obesity complications
Obesity is linked to an increased risk of multiple health problems such as diabetes, high blood pressure, heart disease, sleep apnea, joint problems, and fatty liver disease.
Early identification of individuals at higher risk of complications helps in developing a follow-up program that includes measuring blood pressure, checking blood sugar and cholesterol, assessing liver function, and monitoring growth in children.
Genetic obesity testing remains part of a comprehensive evaluation and is not a substitute for medical examinations or other tests prescribed by a physician.
The difference between genetic testing and traditional tests
Traditional tests measure current health status such as blood sugar, cholesterol, liver function, and hormones, while genetic testing looks for DNA changes that may have been present since birth.
The two analyses can complement each other because genetic analysis helps in understanding the possible cause, while medical examinations reveal the current impact of obesity on the body.
Therefore, undergoing genetic obesity testing does not eliminate the need for regular medical follow-up or adherence to a prevention and treatment plan.
privacy of genetic data
Genetic information is among the most sensitive health data; therefore, testing should be conducted by an entity that applies clear standards for protecting samples, reports, and personal data.
Before conducting the analysis, it is important to know how the data will be used, who can access it, how long the sample will be retained, and how the report will be shared.
