When properly managed and treated, lactose intolerance should not pose any dangers. Only when the condition goes undiagnosed or you fail to properly treat and manage the condition, can you experience significant dangers. MayoClinic.com states that even though lactose intolerance produces uncomfortable symptoms, the condition doesn't affect the digestive tract with long-term complications. If you develop common symptoms that relate to lactose intolerance, call your doctor.
Background
Lactose intolerance is a common condition that typically begins around adolescence. Newborns have a significant amount of the enzyme needed to process the sugar found in milk, lactose. Lactose intolerance is a condition where your body doesn't create enough lactase, the needed enzyme to digest lactose, and causes irritation in the intestines. Because the body cannot absorb lactose in its complex state, the body will rid itself of the sugar with diarrhea and vomiting. You may also develop cramping, bloating, nausea and stomach pain, according to MedlinePlus.
Dehydration
A common concern from lactose intolerance is dehydration if you develop diarrhea. Diarrhea typically occurs within 30 minutes of consuming dairy products. If you don't know you're lactose intolerant or you fail to properly manage your symptoms, you may experience excessive diarrhea, which can cause dehydration. Dehydration occurs when your body loses large amounts of water and salts that are needed for your body to function normally, according to the National Digestive Disease Information Clearinghouse. Symptoms of dehydration include dry mouth, fatigue, dry skin and extreme thirst.
Malnutrition
If you continue to consume dairy products without treatment, you can become malnourished because of gastric symptoms, according to MedlinePlus. Because your body cannot absorb the lactose, the digestive system will only partially process the food in the system, expelling it through diarrhea. Malnutrition is a life-threatening condition that needs to be evaluated by a medical professional. Excessive weight loss, fatigue and weakness are all signs of malnutrition.
Consideration
Most of the dangers of lactose intolerance can be avoided with a proper diagnosis and preventative measures. Once diagnosed, you should avoid all dairy products that contain lactose. Some dairy products are sold as lactose-free because the enzyme, lactase is added during the manufacturing process. Dairy products that contain live, active cultures, such as cheeses and yogurt may have significantly less lactose and may be safe with your condition. Lactase supplements may be used at the first bite of diary to prevent lactose intolerance symptoms.
