Did that milkshake leave you with abdominal cramps and nausea?

Maybe you are one of the unlucky individuals who cannot digest lactose in adulthood.
Lactose intolerance is the reduced ability to digest and absorb the milk sugar lactose, due to decreased production of the lactase enzyme. This causes digestive symptoms like gas, bloating and diarrhea. This may be a temporary reduction of lactase (e.g. after surgery or illness) or a permanent reduction, often due to genetic variation.
Lactase persistence is the opposite to lactose intolerance. Lactase persistent individuals are able to produce the lactase enzyme for their entire lives, meaning they can continue to consume dairy products right through adulthood.
Genetic variation is the strongest predictor of lactose intolerance and lactase persistence. A simple mouth swab is all we need to analyze your DNA and determine whether you are at increased risk of lactose intolerance.
