Lactose intolerance can lead to malabsorption and malnutrition, but these outcomes are highly unlikely because the condition is manageable. Lactose intolerance is a common digestive condition that forms during adolescence in some persons. During growth into adulthood, the body slows down its production of the enzyme needed to properly digest the sugar found in milk products. Only in rare and extreme cases will the condition lead to malabsorption. If you suspect that you're lactose intolerant, talk with your doctor.
Synopsis
In newborns, the body creates a large amount of lactase, the enzyme used to break down lactose, a complex sugar found in milk. As the human body matures, the need for milk decreases and the body naturally stops producing as much lactase as it did during infancy. MayoClinic.com states that every adult is lactose intolerant to a certain degree, but only people with marked symptoms are diagnosed with the condition. If you ingest lactose and you're intolerant, the body cannot absorb the sugar in its complex state, so the body rids itself of the lactose as fast as it can.
Effects
Not being able to properly digest the lactose causes inflammation in the digestive tract, leading to diarrhea, vomiting, nausea, cramping, bloating, gas, abdominal pain and foul-smelling stools, according to MedlinePlus. If the condition goes undiagnosed and you continue to eat excessive amounts of dairy products, you can become malnourished as a result of malabsorption. Other complications include dehydration and excessive weight loss. These symptoms are concerning and need to be discussed with your doctor.
Malabsorption
Malabsorption occurs because the body cannot properly digest the lactose and forces out everything in the digestive tract at the time of consumption. This can lead to vomiting and excessive diarrhea. Foods that are currently in the gut will be expelled before being completely digested, leading to malabsorption. Excessive diarrhea can also cause dehydration, a severe medical condition. If you develop signs and symptoms, such as weight-loss, fatigue, weakness and pale skin, call 911.
Avoidance and Treatment
The most effective way to avoid complications from lactose intolerance, such as malabsorption, is to receive a clinical diagnosis and avoid the consumption of products containing lactose. You can purchase dairy products that are lactose-free. The manufacturer of these products adds lactase during the manufacturing process, eliminating the lactose. You can also purchase lactase enzyme supplements in pill or droplet form that you take at the first bite of dairy.
