Why is a child continuously vomiting, even when drinking water?

Generally, persistent vomiting in children, even when drinking water, may be caused by improper feeding, poor gastrointestinal development, acute gastroenteritis, gastrointestinal-type cold, intestinal obstruction, and other factors. It is recommended to seek timely medical consultation to identify the underlying cause and receive targeted treatment. Detailed analysis is as follows:

1. Improper Feeding

Feeding too quickly or excessively, or feeding while the baby is crying may cause the infant to swallow large amounts of air, leading to vomiting. In older children, overeating, eating too quickly, or consuming irritating foods may also cause vomiting. It is recommended to adjust feeding methods, ensuring the baby fully takes the nipple or bottle teat into the mouth to avoid air intake. After feeding, hold the baby upright and gently pat the back to help release air from the stomach.

2. Incomplete Gastrointestinal Development

Infants' stomachs are horizontally positioned with small capacity, and the lower esophageal sphincter is immaturely developed with poor control, making it prone to gastroesophageal reflux and subsequent vomiting. As children grow older, gastrointestinal function gradually matures, and this condition will improve. Frequent small feedings are recommended, and appropriately elevating the upper body after feeding can help reduce reflux.

3. Acute Gastroenteritis

This is often caused by unclean diet or bacterial or viral infections. Pathogens attack the gastrointestinal tract, causing congestion and edema of the gastrointestinal mucosa, disordered gastrointestinal motility, and symptoms such as vomiting, diarrhea, and abdominal pain. Patients can take medications such as Cefaclor Granules, Fong Liao Gastrointestinal Kang Tablets, and Montmorillonite Powder under a doctor's guidance.

4. Gastrointestinal-type Cold

Mainly caused by viral infection (e.g., Coxsackievirus), often accompanied by mixed bacterial infection. Besides vomiting, symptoms may include fever, nasal congestion, runny nose, and cough. Patients can take antiviral oral liquid, Lianhua Qingwen Capsules, Enteritis安宁 Granules, and other medications as prescribed. Rest well, drink more water, supplement with vitamin C, and enhance immunity.

5. Intestinal Obstruction

Common causes include intussusception, volvulus, and congenital intestinal malformations. Blockage of the intestines prevents normal passage of contents, causing symptoms such as vomiting, abdominal pain, bloating, and cessation of flatus and defecation. Immediate medical attention is recommended for abdominal ultrasound, X-ray, and other examinations to confirm diagnosis. For intussusception, air enema reduction may be attempted first; if reduction fails or the intestinal obstruction is caused by other factors, surgery may be required to relieve the obstruction.

Maintain good lifestyle habits in daily life and avoid consuming spicy and irritating foods such as pepper, chili, and garlic, which may hinder recovery.
