Vomiting through projection: Reasons, solutions, and explanations
**Projectile Vomiting: A Common but Concerning Symptom**
Projectile vomiting, a condition characterised by forceful and sudden expulsion of vomit, can be a cause for concern for both parents and healthcare providers. The causes and treatments of projectile vomiting can vary significantly between infants and adults.
**Causes of Projectile Vomiting in Infants**
In infants, projectile vomiting is often due to a condition called pyloric stenosis. This condition involves a narrowing of the pylorus, the outlet of the stomach, leading to forceful vomiting. Other common causes include gastroesophageal reflux disease (GERD), food allergies, infections, and other digestive issues.
**Causes of Projectile Vomiting in Adults**
In adults, projectile vomiting is more likely to be caused by obstructions in the gastrointestinal tract, infections, neurological disorders affecting the vomiting reflex, or severe GERD. Other causes may include metabolic disturbances, medication side effects, or central nervous system issues.
**Treatments for Projectile Vomiting**
The treatment for projectile vomiting depends on its cause. In infants, pyloric stenosis requires surgical intervention (pyloromyotomy) to correct the narrowed pylorus. Reflux is often managed conservatively with feeding modifications, positioning after feeding, and in some cases, medications to reduce acid or improve motility. Allergies can be managed by eliminating allergenic foods from the mother's diet (if breastfeeding) or from the infant's formula. Infections are treated with supportive care, including hydration, and antibiotics if necessary.
In adults, treatment depends on the underlying cause. Obstructions may require surgery or endoscopic intervention. GERD is typically managed with lifestyle changes, acid suppression medications, and sometimes surgery. Infections are treated according to the causative agent. Supportive care, including hydration and antiemetics, may be used symptomatically.
**Prevention and Complications**
Gastroenteritis, a common cause of projectile vomiting, can be prevented by washing hands regularly and avoiding contact with people until 48 hours after symptoms have disappeared. It is most commonly caused by viruses such as norovirus, which is highly contagious and most common in the winter months. Complications of projectile vomiting can include a torn food pipe (esophageal laceration or Mallory-Weiss syndrome), suffocation or choking, and damage to the lungs if vomit is breathed in. Dehydration from projectile vomiting can cause an infant to seem more sleepy or lacking in energy.
Projectile vomiting should have no long-term side effects for both adults and children, in most cases. However, in some cases, the food pipe may be torn when vomiting, but this is also resolved relatively easily and should not cause lasting damage.
A study found that droplets from projectile vomit can travel a long distance, potentially making the illnesses that cause it highly contagious. It is therefore important to seek medical attention promptly to identify the cause and initiate appropriate treatment to avoid complications.
