Question
A two-month-old baby, primarily breastfed, has recently been discovered to have foamy stools, accompanied by an unpleasant odor, and also has smelly farts. The baby has often passed gas before, but without any odor. What could be the cause of this situation, and how should it be addressed?
Answer
Foamy stools in infants are usually considered to be a case of functional diarrhea. This condition does not require special treatment. Since breast milk contains a higher amount of lactose, and the baby may lack lactase, leading to lactose intolerance. Most of the lactose is decomposed by lactase and produces acid in the intestines, which in turn stimulates the intestines, causing the stools to be loose and foamy. Generally, as the baby grows, lactase activity will gradually mature and increase, allowing for the gradual decomposition, digestion, and absorption of lactose. Additionally, as supplementary foods are introduced, the situation will gradually improve.
