Lactose Intolerance

Lactose intolerance can be described as a condition where a person cannot digest the lactose, or sugar, in dairy products. Its symptoms can include gas production, diarrhea, and digestion problems. However, most people do not realize that a majority of individuals actually have difficulty digesting lactose; it’s just that some people experience actual symptoms or effects. This is alternatively called lactose malabsorption; and it is the difference between the small or large intestine causing the problem. 

To begin with, two major factors can contribute to lactose intolerance, which are lactose malabsorption and gut sensitivity. The small intestine typically requires an enzyme called lactase to break down those sugars in the diary into manageable particles. This is normally produced naturally in our bodies, however, its frequency decreases as we age. If somebody doesn’t have enough lactase, they will be unable to digest lactose, making them lactose intolerant. In addition to this, the unique gut microbiome in your colon might process lactose differently. Therefore, each individual differs in the amount of lactose they are able to consume safely without any concerns. 

The symptoms and effects of intolerance begin as early as 30 minutes after consuming lactose products. The most common ones include nausea, vomiting, diarrhea, cramps, and passing gas. However, most people with lactose intolerance can typically manage the symptoms and the overall condition without giving up all products with lactose. Furthermore, genes are the factor which determines your production of lactase and gut sensitivity. According to Cleveland Clinic, Asian, Native American, and Hispanic individuals are most likely to have lactose malabsorption and intolerance. In addition, studies have shown most people develop lactose intolerance as they grow, because the body gradually stops producing lactase; older people do not need the ability to digest breast milk. 

To test for lactose intolerance, visit a healthcare provider; they have several ways of testing, such as the hydrogen breath test, stool acidity, and for blood sugar. Lactase supplements can also help your body with its lack of the enzyme, allowing you to break down diaries better. Solutions such as experimenting with the tolerance of your body, consuming dairy alternatives such as oat milk or almond milk, and taking supplements such as calcium and vitamin D allows affected individuals to live with the condition.
