Analysis of the causes of student vomiting

Student vomiting may be caused by improper diet, gastroenteritis, food poisoning, motion sickness, psychological stress, and other factors. Vomiting is a protective reflex of the body, and student populations are more likely to experience such symptoms due to incomplete physiological development or weak environmental adaptability.

1. Improper diet

Overeating, consuming raw, cold, greasy foods, or overeating in a short period of time can stimulate the gastrointestinal mucosa. Students often suffer from indigestion due to irregular meal breaks or excessive intake of snacks, manifested as postprandial bloating accompanied by non jet vomiting, with vomit often containing undigested food residues. You can try drinking a small amount of warm ginger water to relieve symptoms. If vomiting persists for more than 6 hours, seek medical attention.

2. Gastroenteritis

Viral or bacterial gastroenteritis is a common cause of campus collective life, often related to norovirus and rotavirus infections. The typical symptoms are sudden vomiting accompanied by watery diarrhea, and some patients may experience low-grade fever. Commonly used drugs in clinical practice, such as montmorillonite powder, oral rehydration salt powder, and bifidobacterium triple active bacterial powder, should be isolated to prevent cross infection.

3. Food poisoning

Severe vomiting occurs 2-6 hours after consuming food contaminated with Staphylococcus aureus and Salmonella. Improper storage of food in student canteens or off campus vendors can easily lead to such situations, often accompanied by systemic symptoms such as abdominal pain and fever. After diagnosis, antibiotics such as berberine hydrochloride tablets and norfloxacin capsules are needed, and those with severe dehydration need intravenous fluid replacement.

4. Motion sickness

Students with sensitive vestibular function are prone to motion sickness when traveling to and from school by car. The balance receptors in the inner ear are stimulated by bumps, which can cause dizziness and vomiting. It is recommended to take Triphenylamine tablets one hour before taking the bus, choose the front seat of the vehicle, and maintain ventilation. Traditional Chinese medicine can also relieve symptoms by pressing the Neiguan acupoint or wearing an anti dizziness wristband.

5. Psychological stress

Exam anxiety or social anxiety may lead to neurogenic vomiting, which belongs to the category of psychosomatic diseases. This type of vomiting often occurs in specific situations, and the discomfort after vomiting actually decreases. Psychological counseling can be combined with traditional Chinese medicine such as Chaihu Shugan San to regulate the liver and regulate qi. Parents should avoid excessive pressure.

Students should maintain a lateral position after vomiting to prevent aspiration, and supplement with light saline solution in small amounts and multiple times during vomiting intervals. It is necessary to cultivate regular eating habits in daily life and avoid drinking cold drinks on an empty stomach or eating immediately after intense exercise. Schools should strengthen the hygiene supervision of canteens and suggest improving Helicobacter pylori testing for students who frequently vomit. If the vomit has blood streaks, coffee grounds, or is accompanied by consciousness disorders, it should be immediately sent to the hospital for screening of intracranial lesions and other urgent and severe cases.
