General Causes of Diarrhea in Formula-fed Babies

For many parents, one of the most concerning issues they may face is their baby’s digestive health. Diarrhea is a common problem in most formula-fed babies, which can cause distress to the infant and their parents. Let’s discuss the primary causes of diarrhea in formula-fed babies to help you understand the root cause of your baby’s poop problem.

Allergic Reaction to Formula

One of the most common reasons infants experience baby diarrhea is lactose intolerance or allergy to the formula they consume. For instance, some breastfed babies are allergic to cow’s milk proteins, while others may be allergic to soy formula or particular types of solid foods. So, if your baby is experiencing vomiting or gas alongside diarrhea, it may be a sign of formula allergy or intolerance.

Infection

Infections are another common cause of baby diarrhea are infections. Since a baby’s immune system is still developing, they become more susceptible to infections, even those that cause diarrhea as a symptom. The most common infections include viral or bacterial infections such as salmonella or norovirus. In most cases, infections like these can cause fever and dehydration.

Antibiotics

Even breastfed babies prescribed antibiotics for any reason may experience diarrhea as a side effect. Antibiotics can disrupt the delicate balance of good and bad bacteria in the gut, leading to diarrhea. However, it is essential to complete the prescribed course of antibiotics to prevent the recurrence of the infection.

Teething

Although teething is an entirely natural process that happens in babies, there are times when it can also cause baby diarrhea. That’s because the increase in the baby’s salivation during teething can often result in baby diarrhea. However, teething is also temporary and should cause you any concern.

So, it’s essential always to follow the pediatrician’s recommended schedule of feeding to avoid mild diarrhea.

Do Switching Formulas Cause Diarrhea?

Every parent has a strategy for providing nutrients for their child. While some prefer breast milk, others prefer giving infant formula to their babies. Parents can switch between many infant formulas on the market to meet their baby’s needs.

However, there are instances when switching formula products can cause diarrhea in some formula-fed babies. Diarrhea is a common issue that occurs when there is a change in the baby’s digestive system. Here are some of the reasons why switching formulas can cause diarrhea in some babies:

Remember that different types of formulas have different nutritional compositions, including different amounts and types of proteins, fats, and sugars.

Bacterial Contamination

Although it rarely happens, switching formulas can cause a baby’s diarrhea because of bacterial contamination. Contamination from harmful bacteria like E. coli or Listeria can occur if the formula isn’t prepared or stored correctly.

However, the duration of diarrhea may vary depending on the baby’s age, health, and the primary cause of the loose stools.

Sensitivity to Something in Mom’s Diet

One of the most common reasons why many breastfed babies experience diarrhea is when there are changes in the mother’s diet. Some diets may cause the infant’s digestive system to react, causing diarrhea. Foods usually have this effect: dairy, soy, wheat, eggs, caffeine, and spicy foods. If a mother suspects that her diet is causing diarrhea in her baby, she can try eliminating certain foods to see if there is an improvement in the baby’s symptoms.

Infection

Infection can also cause infant diarrhea. Otherwise known as viral diarrhea, babies are more prone to infections because of their developing immune systems. The most common infections include norovirus and rotavirus. When this happens, the infection is usually accompanied by other symptoms such as fever, dry mouth, and vomiting. When this happens, it’s crucial to reach out to the doctor immediately.
