How does gluten sensitivity work?

Gluten intolerance

Celine Haarhoff

Gluten intolerance, also known as celiac disease, is a condition in which a person experiences negative symptoms after consuming gluten, a protein found in wheat, barley, and rye. These symptoms can range from digestive issues, such as bloating and abdominal pain, to fatigue, brain fog, and skin irritation.

Their genes determine a person's genetic predisposition to gluten intolerance. The human genome contains all the genetic information that makes up a person, including their predisposition to various medical conditions. Several genes have been linked to gluten intolerance, including the HLA-DQ2 and HLA-DQ8 genes. These genes are involved in the immune system's response to gluten.

People with the HLA-DQ2 and HLA-DQ8 genes are more likely to develop gluten sensitivity or intolerance but it is important to note that not everyone with these genes will necessarily develop the condition. Other factors, such as the person's environment and lifestyle, also play a role in the development of the condition.

Symptoms of gluten intolerance can vary greatly from person to person.

Some common symptoms after gluten consumption include:

  • Digestive issues, such as bloating, abdominal pain, diarrhea, and constipation
  • Fatigue
  • Brain fog
  • Skin irritation, such as rashes or eczema
  • Joint pain
  • Depression and anxiety
  • Headaches

These symptoms can be similar to other conditions, such as irritable bowel syndrome (IBS). Hence, a person must consult a doctor for a proper diagnosis.

DNA testing can help to determine a person's genetic predisposition to gluten intolerance. A genetic test can identify any genes linked to the condition by analyzing a person's DNA. This information can be useful for people experiencing symptoms related to gluten intolerance, as it can help confirm or rule out the condition as a possible cause.

However, it is important to note that a positive result from a genetic test for gluten intolerance does not necessarily mean that a person has the condition. As mentioned earlier, other factors can influence the development of gluten intolerance, and a person with the relevant genes may never develop the condition.

Additionally, genetic testing is not a substitute for a proper medical diagnosis. A doctor will consider a person's symptoms, medical history, and other factors when diagnosing gluten sensitivity or any other medical condition. Genetic testing may, however, aid in diagnosing gluten intolerance.

In conclusion, genes determine a person's genetic predisposition to gluten intolerance. Several genes have been linked to the condition, including the HLA-DQ2 and HLA-DQ8 genes.

Gluten intolerance symptoms can vary, including digestive issues, fatigue, and skin irritation. DNA testing can help to determine a person's genetic predisposition to the condition, but it is not a substitute for a proper medical diagnosis.
