Foamy Stool In Infants – Causes And What Parents Should Know

When an infant passes foamy stool, it is often a sign of diarrhea or digestive issues. Common causes include a cold stomach due to exposure to cold, improper feeding, breast milk-induced diarrhea, and lactase deficiency in young infants. Secondary lactase deficiency can also occur due to various factors such as intestinal viral infections like rotavirus or norovirus, and food protein allergies. These conditions can damage the intestinal lining, leading to reduced production of lactase, the enzyme responsible for digesting lactose.

Understanding Lactose Intolerance In Infants

When lactase levels are low, the infant's body cannot properly digest lactose, resulting in lactose intolerance. This leads to undigested lactose passing through the digestive tract, causing symptoms such as foamy, watery stools. This type of stool is often referred to as "foamy stool" and can be alarming for parents. In addition to lactose intolerance, infants may also develop foamy stools due to acute gastroenteritis, which often comes with symptoms like diarrhea, vomiting, abdominal pain, and fever.

Other Possible Causes Of Foamy Stools

Medications, especially certain traditional Chinese herbal remedies used to clear heat from the upper respiratory system, may also cause loose stools or diarrhea in infants. These medicines can have a laxative effect, contributing to the appearance of foamy or watery bowel movements.

How To Care For An Infant With Foamy Stool

If your baby is experiencing foamy stools, it's important to keep their abdomen warm to support digestion and reduce discomfort. Applying a warm compress or using a safe abdominal therapy can help soothe the digestive system. Probiotics may be given orally to help restore healthy gut bacteria and improve digestion. Medications like Smecta (attapulgite) can be used to help reduce diarrhea and firm up stools.

For infants with lactose intolerance, lactase enzyme supplements can be added to breast milk or formula to help break down lactose more effectively. Alternatively, a lactose-free formula may be recommended by a pediatrician. If symptoms persist despite home care or if the frequency of diarrhea increases significantly, it is important to seek medical attention. A healthcare provider can perform tests to determine the underlying cause and provide targeted treatment to help your baby recover quickly.
