Lactose intolerance is when a person has an adverse reaction to products that contain dairy. Lactose is the sugar found in dairy products such as milk, cream, butter, cheese and yogurt. It is common globally, with an average of 65% of the global population being affected.
Lactose Intolerance and Genetics
Although lactose intolerance can be an independent congenital disorder, having no prior family history, it can, in fact, also be inherited genetically. This form is the most common, and is known as primary lactose intolerance. Congenital lactose intolerance is a rare condition found in babies, where both parents contribute genetically.
Although the gene is present where the disorder is inherited, symptoms may only start to appear in early adulthood. Therefore, if your immediate relatives are showing symptoms and the disorder has been confirmed, you can take a DNA health test to determine if you will develop these symptoms later on.
Lactose Intolerance Symptoms
Like with most disorders and diseases, lactose will affect each person differently. Once you know that you are prone to it, you can start to make lifestyle changes accordingly to avoid discomfort. If it is ignored, it can cause severe damage to your body. Some common lactose intolerance symptoms to look out for after ingesting dairy include:
- Occasional vomiting
- Uncomfortable gas
If you are experiencing these symptoms after consumption of dairy, you may want to stock up on lactose-free alternatives.
If you’re still asymptomatic, and concerned that this might become a problem for you in future, a DNA health test will be able to prepare you for what’s to come, with trained medical professionals offering advice on going forward.
