A child who has vomited repeatedly for three days may need more than routine treatment for a stomach infection.
Doctors must determine whether the digestive tract is functioning normally.
If an obstruction is suspected, the child may need to be admitted to the hospital.
Medical teams can provide intravenous fluids, monitor electrolyte levels, and use imaging examinations to investigate the cause.
Depending on the severity, the treatment may involve temporarily avoiding food and drink by mouth, decompression of the stomach using a tube, and specialist evaluation.
Some patients improve with medical management.
Others may require an endoscopic procedure or surgery to remove the obstruction.
The appropriate approach depends on the child's condition and the exact location and severity of the blockage.
This is why parents should not wait until a child becomes extremely weak before seeking medical help.
Persistent vomiting, severe abdominal pain, or a swollen abdomen deserves urgent assessment.
If the child is difficult to wake, has severe breathing difficulties, faints, or shows signs of shock, emergency services should be contacted immediately.
The most important lesson is that a seemingly ordinary digestive complaint can occasionally be the first sign of a serious abdominal emergency.
Chapter 4: How Doctors Discover the Parasites and Decide on the Right Treatment
When a child arrives at the hospital after several days of vomiting, doctors do not immediately assume that intestinal worms are responsible.
The first priority is to determine whether the child is dehydrated, whether an intestinal obstruction is present, and whether another emergency condition could explain the symptoms.
The examination usually begins with a detailed medical history.
Doctors may ask when the vomiting started, how frequently it occurs, whether the child has abdominal pain, and whether bowel movements have changed.
They may also ask about appetite, weight loss, previous episodes of stomach discomfort, and recent outdoor activities.
The child's living environment and exposure to potentially contaminated food or water may also be relevant.
1. Physical examination
Doctors examine the abdomen to look for swelling, tenderness, unusual firmness, and other signs that may suggest an obstruction.
They may listen to bowel sounds and assess whether the child shows signs of dehydration.
Blood pressure, heart rate, temperature, and oxygen saturation are also monitored.
In a seriously ill child, these measurements help determine whether immediate stabilization is necessary.
2. Stool examination
A stool sample can help identify intestinal parasite infections.
Laboratory technicians examine the sample under a microscope to look for parasite eggs.
In ascariasis, the eggs have characteristic microscopic features that help distinguish them from those of other intestinal parasites.
However, a single stool examination does not always detect every infection.
For example, an infection involving immature worms may not yet produce detectable eggs.
Doctors may therefore request additional testing when symptoms and examination findings suggest a parasite infection despite an initially negative result.
The CDC identifies microscopic examination of stool for parasite eggs as a common diagnostic method for ascariasis.

3. Blood tests
Blood tests can provide additional information.
A complete blood count may reveal changes in white blood cells, including an increased number of eosinophils.
Eosinophils are a type of white blood cell that can increase in certain parasitic infections and allergic conditions.
However, an elevated eosinophil count does not prove that a child has intestinal worms.
Doctors interpret the result alongside symptoms and other findings.
Additional blood tests may assess:
-
Electrolyte levels.
-
Kidney function.
-
Signs of dehydration.
-
Inflammation and infection.
-
Liver function when clinically indicated.
These measurements help doctors understand how severely the illness is affecting the child's body.
4. Ultrasound and abdominal imaging
When intestinal obstruction is suspected, imaging becomes particularly important.
An abdominal ultrasound may help identify abnormal intestinal contents, enlarged bowel loops, and certain appearances associated with worm masses.
An abdominal X-ray may reveal dilated intestinal loops and other signs of obstruction.
In selected cases, doctors may recommend additional imaging to clarify the diagnosis or identify complications.
The choice depends on the child's condition, age, and clinical findings.

How is ascariasis treated?
The treatment depends on whether the child has an uncomplicated infection or a serious complication such as intestinal obstruction.
For uncomplicated ascariasis, doctors commonly prescribe antiparasitic medication.
Medicines such as albendazole and mebendazole are used to treat infections caused by intestinal roundworms.
These medications act against the parasites and help eliminate the infection.
Treatment is generally effective, but the choice of medicine and appropriate regimen must be determined by a healthcare professional.
The CDC lists albendazole, mebendazole, and other antiparasitic medicines among the treatment options for soil-transmitted helminth infections.

However, an important distinction must be made.
A child with an intestinal blockage should not simply be given routine deworming medicine at home.
An obstruction requires urgent medical assessment.
Depending on the severity, doctors may first stabilize the child with intravenous fluids and correct electrolyte disturbances.
They may temporarily stop oral feeding, monitor the abdomen, and use a tube through the nose into the stomach to remove accumulated fluid and gas when necessary.
If the obstruction does not resolve or serious complications develop, specialist procedures or surgery may be required.
In some situations, doctors may remove the obstructing worm mass through surgery.
The decision depends on whether the intestine remains healthy, whether blood flow is adequate, and whether perforation or other complications have occurred.
What happens after treatment?
Recovery does not end when the vomiting stops.
Doctors may monitor the child to make sure that normal bowel function returns.
They may also assess nutritional status, weight, appetite, and possible anemia or nutritional deficiencies.
If the child has experienced a heavy infection, additional follow-up may be necessary.
Parents should follow the prescribed treatment plan and attend any recommended appointments.
They should not stop medication early, repeat doses unnecessarily, or give several deworming products together without medical advice.
