Lactose intolerance doesn't typically cause behavioral changes in adults, but it is very common for it to affect behavior in infants and children. According to BabyCenter, one of the primary signs and symptoms of a baby who is lactose intolerant is excessive crying and fussiness. The behavioral issues that form from being lactose intolerant are because of uncomfortable and at times painful symptoms. If you suspect that you or your child is lactose intolerant, talk with a doctor for further evaluation and diagnosis.
Lactose Intolerance
If you notice that every time your baby or child consumes dairy products, her behavior changes, she may be lactose intolerant. Most cases of lactose intolerance develop during adulthood, but they can occur in early childhood, especially in premature babies, according to TeensHealth. The condition is caused by a deficiency in the digestive system. Your small intestines make certain enzymes to break down the lactose, the sugar found in milk. If the small intestines don't produce enough of the appropriate enzyme, lactase, you will develop common lactose intolerance symptoms.
Behavioral Issues
Most behavioral issues will develop within 20 minutes after your child or infant has consumed a dairy product. Symptoms from lactose intolerance include stomach pain, gas, bloating, cramping, diarrhea, nausea and foul-smelling stools, according to MayoClinic.com. If your child or baby develops pain or discomfort in his digestive system, he will cry, fuss and may become inconsolable. If your baby is breastfed, talk to the pediatrician about alternatives, because breast milk contains lactose.
Treatment
Behavioral issues from lactose intolerance are corrected and prevented through treating the condition. Lactose intolerance has no cure, but it is manageable through dietary changes and supplementation. You may completely eliminate dairy products from your diet and substitute them with soy, rice or coconut-based alternatives. You may add the lactase enzyme to the dairy product before you consume it. Lactase supplements are sold at pharmacies in liquid and pill forms. Purchase lactose-free dairy products to prevent lactose intolerance symptoms.
Milk Allergy
If you notice severe behavioral problems after your child or baby consumes dairy products, you should talk to her doctor about the possibility of a milk allergy. A milk allergy will cause digestive complications along with skin rashes, asthma and nasal congestion. A milk allergy may lead to serious complications.
