Sugar intolerance can be caused by a deficiency of the lactase enzyme, leading to uncomfortable symptoms such as diarrhea, bloating, and excessive gas. Different types of sugar intolerance include fructose intolerance, sugar allergy, and lactose intolerance, which can be diagnosed by a medical professional and managed through medication, supplements, and dietary plans.
Sugar intolerance describes any condition in which the body cannot absorb basic sugars. Different types of sugar intolerance include fructose intolerance, sugar allergy, and even lactose intolerance.
The main cause of sugar intolerance is a deficiency of the lactase enzyme. This enzyme is meant to break down sugars into digestible forms so they can be digested or absorbed by the body, and a deficiency makes this very difficult or even impossible. When this enzyme is missing, a bacterium residing in the digestive tract can ferment into gas, leading to many uncomfortable symptoms.
Fructose intolerance is a fairly rare condition, affecting approximately one in 10,000 individuals. Many people confuse it with sugar or fructose malabsorption, but they are two very different conditions. Fructose intolerance is a condition in which the enzymes to break down sugars are not produced. This intolerance can be passed down genetically and will last a lifetime. Fructose malabsorption is much more common, affecting more than 30% of the population. This happens when epithelial cells are not available to help with digestion. Nearly one in three people experience some type of sugar sensitivity, but many have no symptoms.
Symptoms of a sugar allergy can include diarrhea, bloating, and excessive gas. These symptoms will appear a few hours after consuming drinks or foods that contain simple or even complex sugars. An individual can avoid this condition by staying away from common foods that contain sugar or fructose. Fruits, juices, and soft drinks contain large amounts of these ingredients and should be avoided.
Lactose intolerance occurs when the lactase level is too low or absent and the molecule, which consists of two sugar molecules linked together, cannot be broken down and digested. Those who have this form of sugar intolerance are commonly advised to take a lactase supplement before consuming any foods that contain sugars. Many also choose to substitute soy, nut, or lactose-free milk for regular milk. There are many types of foods that may contain lactose or sugars that should be avoided or eaten in moderation.
Most of those who believe they may have a sugar intolerance can see a medical professional for diagnosis. If a professional diagnosis reveals a sugar intolerance of any kind, then the patient can be counseled on how to combat the problem. Medications or supplements may be issued, and typically the patient will work closely with physicians or nutritionists to develop a dietary plan. The most effective way to live with sugar intolerance, if it is not treatable, is to learn which foods to avoid.
