Foul-smelling yellowish-white stool, how to treat

Patient's question:

Doctor
Hello,
My child (male, 1 year 3 months) had vomiting last night and had a bowel movement this morning. The stool was yellowish-white and had a sour odor. When burping, there was an odor, but his spirits were good. Please diagnose the symptoms and provide treatment advice. Thank you!

Doctor's answer:

Due to the immature digestive function of infants and young children, if their diet is not properly regulated, it is easy to accumulate food, which can lead to discomfort reactions such as vomiting, stomach pain, fever, loss of appetite, coughing, diarrhea, and constipation. Mothers can supplement their babies with Yitong probiotics to improve their intestinal function and promote digestion and absorption, so the baby won't always feel indigestion.
It is recommended that you pay attention to your baby's rest, avoid overexertion and mental stress, ensure warmth, and avoid getting cold. Drink plenty of warm water, and you can take Huoxiang Zhengqi soft capsules and Zhengchangsheng orally for treatment. Maintain a regular diet, appropriately control your baby's food intake, and eat small meals frequently.
