Patient's question:
My child has diarrhea and isn't eating; she is breastfed, and the medicine she's taking hasn't shown any improvement. What should I do? The kind of assistance I'm looking for: I want to ask the doctor what I should do...Doctor's answer:
There are many causes of nausea and vomiting, which can be broadly categorized into two major groups: non-infectious and infectious factors.1. Non-infectious Factors
Infants have immature digestive systems, producing low amounts of gastric acid and digestive enzymes with low activity. They cannot tolerate significant changes in the type or quantity of food consumed. Improper diet or feeding methods can both lead to nausea and vomiting. For example:
- Excessive, insufficient, or irregular bowel movements, changes in stool composition, or excessive sugar intake.
- Early introduction of complementary foods like egg yolks, porridge, or vegetables, which may be difficult for infants to digest.
- Weaning a child in hot weather, which can easily alter dietary content.
All of these can trigger infant diarrhea. Additionally, changes in climate can also cause nausea and vomiting. For instance, exposure to cold can disrupt intestinal function, while hot weather or over-wearing clothes can increase gastric acid and digestive enzyme secretion, leading to indigestion and subsequent nausea and vomiting.
2. Infectious Factors
Infectious diseases of the gastrointestinal tract. Bacteria, viruses, fungi, or protozoa may enter the digestive system through contaminated food, or spread via improperly cleaned utensils, hands, or toys. Spoiled or (decomposed) food contaminated with bacteria can also cause gastrointestinal disorders, resulting in nausea and vomiting. Long-term use of broad-spectrum antibiotics may directly affect the intestines, leading to nausea and vomiting. Therefore, it is essential to understand the physiological growth and development characteristics of infants, master proper feeding techniques, and provide adequate health and hygiene education to reduce the occurrence of infant diarrhea.
