The main causes of diarrhea in children

The main causes of diarrhea in children include infectious factors, improper diet, allergic reactions and immature digestive system. Appropriate response methods should be selected according to the specific causes, including drug intervention, dietary adjustments and improved hygiene habits.

1. Infectious factors

Bacterial infection is the most common cause of diarrhea in children, including viruses such as rotavirus and norovirus, bacteria such as E. coli and Salmonella, and parasites such as Giardia. Infection is usually transmitted through contaminated food, water, or contact with contaminated objects. The response methods include: ① Ensure that children drink clean and safe water; ② Prevent children from eating unclean or spoiled food; ③ When serious infection such as high fever and bloody stool is found, seek medical attention in time. The doctor may prescribe antibiotics or antiviral drugs, such as cephalosporins, oseltamivir, etc.

2. Improper diet

Excessive intake of sugar, lactose intolerance or inappropriate complementary foods can easily cause diarrhea. For example, introducing milk or other high-protein foods too early may increase the gastrointestinal burden on children. Recommendations: ① Choose probiotic-rich dairy products or probiotic granules to adjust the intestinal flora; ② Add complementary foods slowly and observe the child's digestive response; ③ Stop eating foods that may cause hypertrophy during diarrhea, and give priority to light, easily digestible foods such as rice porridge and applesauce.

3. Allergy or intolerance

Some children react to specific foods such as milk protein, eggs or environmental factors such as pollen and dust mites. Chronic diarrhea may be a manifestation of allergies to the above factors. It is recommended that parents adjust the diet after confirming the diagnosis through allergen testing, and supplement amino acid milk powder or deep hydrolyzed milk powder when necessary. Try to avoid contact with environmental factors known to cause allergies.

4. Immature digestive system

Especially for children under 3 years old, their digestive enzymes and gastrointestinal barrier functions are not fully mature yet, and they are prone to diarrhea due to slight stimulation. At this time, you need to pay attention to: ① Try to breastfeed, breast milk contains immune factors and probiotics, which help improve intestinal resistance; ② If diarrhea occurs frequently, consult a doctor to use drugs that help digestion, such as lactulose or pancreatic enzyme supplements.

5. Hygiene and environmental factors

Children's hand hygiene and environmental hygiene can also cause diarrhea. Bacteria and viruses can spread quickly if fingers are put into mouths or unclean toys are shared. Improving hygiene habits can help reduce the risk of diarrhea, including: washing hands frequently, disinfecting toys regularly, and avoiding contact with sick children.

Although diarrhea is common, if obvious dehydration symptoms occur, such as crying without tears, significantly reduced urine output, dry lips, etc., you should seek medical attention immediately to prevent severe dehydration from endangering your life. At the same time, parents can prevent diarrhea by scientifically adjusting their diet and paying attention to hygiene, and enhance their children's ability to absorb nutrients and immunity.
