Lactose is a type of sugar found in dairy products. It consists of galactose and glucose. For most of us, lactose is easily digested along with the rest of our food, but not everybody is so fortunate.
Many people have an intolerance to this sugar, which can lead to some quite uncomfortable symptoms. Therefore, people with lactose intolerance need to stay away from those dairy products that they cannot digest.
The severity of the symptoms often varies from person to person, along with the types of dairy products that can affect them. Here are some of the symptoms that people with lactose intolerance are likely to encounter.
Lactose Intolerance Sign #1: Nausea and Vomiting
Nobody enjoys the feeling of nausea, but most times you experience it, it’s to your benefit. Nausea creates an urge to expel unwanted substances from the body’s digestive tract, thus getting rid of toxins, pathogens, or anything else that should not be there.
People with lactose intolerance may find that undigested food can rest in their stomach without getting broken down and moved along to the intestines. If it stays there for too long, the body will find a way to eject it from the body. Vomiting does not always occur, but nausea is a fairly common symptom.
