Worm infections are common in children, particularly in places where exposure to contaminated soil, food or water is possible. A child may have a worm infection without obvious symptoms, while others may develop abdominal discomfort, diarrhoea, poor appetite, itching around the anus, tiredness or problems with nutrition.
The good news is that most intestinal worm infections can be treated effectively with appropriate anti-worm medicines. But deworming is not simply about giving a tablet and forgetting about the problem. Good hygiene, safe food and water, sanitation and preventing reinfection are equally important.
The World Health Organization (WHO) recommends periodic deworming for children living in areas where soil-transmitted worm infections are common. These infections include roundworm, whipworm and hookworm and can interfere with nutrition, cause anaemia and, when infections are significant, affect children’s physical development.
In India, the National Deworming Day programme aims to reach children and adolescents aged 1–19 years through schools and Anganwadi centres. The National Health Mission currently describes two rounds each year, on 10 February and 10 August.
What is deworming in children?
Deworming means treating a child with an appropriate anthelmintic medicine to kill or remove intestinal parasitic worms.
Common soil-transmitted worms include:
- Roundworms (Ascaris)
- Whipworms (Trichuris)
- Hookworms
Pinworms are another common intestinal parasite, particularly among children. They are different from soil-transmitted helminths and have some differences in diagnosis and treatment.
Worms can enter the body when children accidentally swallow microscopic eggs from contaminated soil, food, water or hands. Hookworm larvae can also penetrate the skin, particularly when someone walks barefoot on contaminated soil.

How do I know if my child needs deworming?
Not every child who has stomach pain or changes in appetite necessarily has worms.
A child may need evaluation or deworming when there are symptoms suggesting a parasite infection, a confirmed infection, repeated exposure or when the child lives in an area covered by a public-health deworming programme.
Possible clues include:
- Persistent or recurrent abdominal discomfort
- Anal itching, particularly at night
- Unexplained diarrhea
- Nausea
- Poor appetite
- Weight loss or poor weight gain
- Tiredness or weakness
- Anaemia
- Nutritional deficiencies
- Seeing worm-like material in stool
- A confirmed worm infection in another household member, particularly pinworm
However, symptoms alone cannot reliably confirm worms. Depending on the suspected parasite, a doctor may recommend a stool examination, a pinworm tape test or another appropriate evaluation. For pinworm, the tape test is commonly used, while routine stool testing is generally not the preferred test.
What are the symptoms of parasites in children?
Symptoms depend on the type and number of parasites.
Some children have no symptoms at all. Others may experience:
- Abdominal pain or discomfort
- Diarrhoea
- Nausea
- Reduced appetite
- Bloating
- Fatigue
- Poor weight gain
- Weight loss
- Anaemia
- Nutritional problems
- Itching around the anus
- Restless sleep
Heavy soil-transmitted helminth infections can interfere with nutrient intake and absorption and may cause intestinal inflammation, blood loss and anaemia.
What are the signs your child has worms?
One of the most recognisable signs depends on the type of worm.
For pinworms, persistent itching around the anus at night is particularly characteristic. Parents may sometimes notice tiny, white, thread-like worms around the child’s anus or on underwear or bedding.
For other intestinal worms, signs can be less specific. Poor growth, abdominal symptoms, diarrhoea, weakness or anaemia may occur, especially with heavier infections.
Because these symptoms can have many other causes, parents should avoid assuming that every digestive problem means worms.
What are the first signs of stomach worms?
There isn’t one universal “first sign” of intestinal worms.
Some children have no symptoms initially. When symptoms occur, early complaints can include mild abdominal discomfort, changes in appetite, nausea or altered bowel habits.
With pinworm infection, night-time anal itching is often the most noticeable symptom.
How do kids act when they have worms?
A child with a significant worm infection may appear tired, less energetic or less interested in food. Poor sleep can occur when pinworms cause persistent night-time itching.
Parents might notice:
- Irritability
- Restlessness at night
- Scratching around the bottom
- Reduced appetite
- Difficulty concentrating
- Tiredness during the day
- Poor weight gain
These behaviours aren’t specific to worms, however. A child acting differently should be assessed in context rather than being diagnosed based on behaviour alone.
What are five diseases caused by worms?
Several different diseases are caused by parasitic worms. Examples include:
- Ascariasis – caused by roundworms.
- Trichuriasis – caused by whipworms.
- Hookworm infection – caused by hookworms.
- Enterobiasis (pinworm infection) – caused by Enterobius vermicularis.
- Schistosomiasis – caused by parasitic blood flukes.
The first three are major soil-transmitted helminth infections. Schistosomiasis is a different parasitic disease and is not an intestinal worm infection in the same sense.
What kills intestinal worms?
The most reliable treatment is an appropriate anthelmintic medicine.
Medicines such as albendazole and mebendazole are commonly used against several soil-transmitted intestinal worms. The exact medicine, dose and duration depend on the parasite, the child’s age and weight, and local medical guidance.
India’s National Deworming Day programme uses albendazole for children and adolescents aged 1–19 years through schools and Anganwadi centres. Current National Health Mission information describes two programme rounds annually.
Parents should not select or repeat an anti-worm medicine based only on symptoms. Children under two years of age, very young children, children with significant illness and those with persistent symptoms should receive age-appropriate medical advice before treatment.
What is the best time to give deworming medicine to kids?
There is no single universal time of day that is “best” for every deworming medicine.
The correct timing depends on the medicine being used and the instructions provided by the healthcare professional or public-health programme.
For routine public-health deworming, the important factor is receiving the recommended treatment on the designated date rather than trying to find a particular hour of the day.
For example, India’s National Deworming Day programme is conducted through schools and Anganwadi centres, with current NHM guidance identifying 10 February and 10 August as the two annual programme dates.
How many times should a child be dewormed?
There is no one schedule that applies to every child everywhere.
WHO recommends annual deworming in areas where the prevalence of soil-transmitted helminth infection is above 20%, and twice-yearly treatment where prevalence exceeds 50%, as part of public-health programmes.
India’s National Deworming Day programme currently provides deworming in two rounds each year for children aged 1–19 years.
That does not mean parents should independently give their child deworming medicine every six months without considering age, medical history and local recommendations.
Do all kids need deworming?
Not necessarily.
There is an important distinction between individual treatment and population-level preventive deworming.
In areas where worm infections are common, WHO supports periodic preventive treatment for at-risk children even without individual testing.
India’s National Deworming Day is designed to reach children and adolescents aged 1–19 years through schools and Anganwadi centres.
Outside such programmes, a child with symptoms may need individual assessment rather than simply taking a deworming tablet.
How to naturally deworm a child?
There is no proven food, juice or home remedy that can reliably replace appropriate anti-parasitic treatment when a child has an intestinal worm infection.
Instead of relying on “natural deworming,” focus on preventing reinfection:
- Wash hands thoroughly with soap after using the toilet.
- Wash hands before eating and handling food.
- Keep children’s fingernails short and clean.
- Discourage nail biting and putting fingers in the mouth.
- Wash fruits and vegetables thoroughly.
- Cook food properly.
- Use safe drinking water.
- Encourage children to wear footwear outdoors.
- Use toilets and maintain good sanitation.
- Wash bedding and underwear regularly when pinworm is suspected.
Handwashing is particularly important for preventing pinworm transmission.
What foods get rid of worms in kids?
No specific food has been proven to reliably eliminate intestinal worms in children.
You may hear recommendations for garlic, pumpkin seeds, papaya seeds, turmeric or other foods as “natural dewormers.” While these foods can form part of a healthy diet, they should not be considered a substitute for proven anti-parasitic treatment.
After deworming, the goal should be a balanced diet containing:
- Protein-rich foods
- Fruits
- Vegetables
- Whole grains
- Iron-rich foods
- Adequate fluids
Good nutrition is especially important because significant worm infections can contribute to nutritional problems and anaemia.
What should you avoid after deworming?
There is generally no special “worm-free diet” that a child must follow after taking a standard deworming medicine.
Unless a healthcare professional gives different instructions, children can usually continue eating a normal balanced diet.
Rather than avoiding particular foods, focus on:
- Safe food preparation
- Clean drinking water
- Handwashing
- Properly washed produce
- Adequate nutrition
If the prescribed medicine has specific instructions about food or timing, follow those instructions.
How long does deworming medicine take to work?
This depends on the parasite and the medication.
Some soil-transmitted helminth treatments are given for only one to three days, and these medicines are highly effective when used appropriately.
That doesn’t necessarily mean every worm will disappear immediately or that all symptoms will resolve on the same day.
Pinworm treatment is a good example. Medication kills worms but does not kill their eggs, which is why treatment commonly involves a second dose two weeks after the first.
How long will worms come out after deworming?
There is no fixed number of days during which worms must appear in the stool.
Some children may notice worms or worm fragments after treatment, while others may not see anything at all. Not seeing worms does not mean the medicine did not work, and seeing worms does not necessarily mean treatment has failed.
The response depends on the type of worm, the medicine used and the child’s level of infection.
Will I poop out worms after deworming?
Possibly, but not always.
Some intestinal worms or pieces of worms may be visible in stool after treatment. Others may be broken down or passed without being noticed.
Parents should therefore not judge whether deworming worked simply by looking for worms in the toilet.
If symptoms continue, worms are repeatedly visible or there is uncertainty about the diagnosis, speak with a paediatrician or healthcare professional.
Do worms come out dead after treatment?
They can.
Depending on the parasite and medicine, worms may be passed in stool after they have been killed or paralysed. They may appear dead, partially broken down or may not be visible at all.
The appearance of the stool isn’t a reliable way to determine whether the infection has been completely treated.
How do I know if worms are gone?
The answer depends on the type of worm.
Improvement in symptoms—such as reduced anal itching, better appetite or improved abdominal symptoms—can be reassuring, but symptoms alone cannot always confirm eradication.
For some infections, a healthcare professional may recommend follow-up testing. With pinworm, repeat infection is common, which makes hygiene and appropriate repeat treatment particularly important.
If your child’s symptoms continue despite treatment, don’t simply keep repeating deworming medicine. The original diagnosis may be incorrect, there may be reinfection or another medical condition may be causing the symptoms.
Why is deworming important for children?
Children are particularly vulnerable to the nutritional consequences of persistent worm infections.
WHO notes that soil-transmitted helminths can cause intestinal inflammation, diarrhoea, impaired nutrient intake and absorption, and blood loss that can contribute to iron-deficiency anaemia.
Four potential areas affected by significant worm infections:
- Malnutrition
- Reduced school attendance
- Reduced physical and cognitive development
- Reduced economic productivity
These concerns are particularly relevant when worm infections are heavy or persistent. Effective control combines appropriate medication with hygiene, sanitation and prevention of reinfection.
How can parents prevent worms from coming back?
Deworming treats the current infection, but children can become infected again.
Prevention starts with simple everyday habits:
1. Encourage proper handwashing
Children should wash their hands with soap after using the toilet and before eating. This is particularly important for preventing pinworm transmission.
2. Keep fingernails short
Worm eggs can collect underneath fingernails. Discourage nail biting and thumb sucking.
3. Wash fruits and vegetables
Wash, peel or cook produce appropriately, particularly when it may have been exposed to contaminated soil or water.
4. Encourage children to wear footwear
Wearing shoes or sandals can help reduce exposure to hookworm larvae in contaminated soil.
5. Maintain clean bedding and clothing
When pinworm is suspected or confirmed, regularly washing underwear, nightwear, towels and bedding can help reduce reinfection. CDC recommends careful laundering and hygiene measures for two weeks after the last treatment dose.
6. Use toilets and safe sanitation
Good sanitation reduces contamination of soil with parasite eggs and is an essential part of long-term worm control.
When should you take your child to a doctor?
Consult a paediatrician or healthcare professional if your child has:
- Persistent abdominal pain
- Blood in the stool
- Persistent diarrhea
- Unexplained weight loss
- Poor growth
- Significant weakness or tiredness
- Suspected anaemia
- Repeated worm infections
- Persistent anal itching
- Vomiting or severe abdominal symptoms
- A large number of worms in the stool
Seek urgent medical care if your child develops severe abdominal pain, repeated vomiting, marked weakness, difficulty breathing, dehydration or other severe symptoms.
A healthcare professional can determine whether testing is necessary and select the appropriate treatment.
Frequently Asked Questions About Deworming in Children
1. Can I deworm my child without a doctor’s advice?
In regions with established public-health deworming programmes, children may receive preventive treatment through those programmes. Outside such programmes, particularly for very young children or children with symptoms, it is sensible to seek medical advice before giving medication.
2. Is deworming medicine safe for children?
Commonly used medicines such as albendazole and mebendazole have extensive use in children, but safety and dosing depend on age, the medicine and the clinical situation. Follow the recommended dose rather than giving an adult preparation or changing the dose yourself.
3. Can worms cause anaemia in children?
Yes. Hookworms in particular can cause intestinal blood loss, and significant soil-transmitted helminth infections can contribute to iron-deficiency anaemia.
4. Can a child get worms again after deworming?
Yes. Deworming does not provide permanent immunity. Reinfection can occur, particularly where exposure to contaminated soil, food or water continues. Pinworm infections are also well known for recurring within households and childcare settings.
5. Does every child with stomach pain need deworming?
No. Stomach pain has many possible causes. A child with persistent or severe abdominal symptoms should be evaluated rather than automatically being given an anti-worm medicine.
6. Can I use garlic or pumpkin seeds instead of deworming medicine?
There is insufficient evidence to rely on these foods as a replacement for proven anti-parasitic treatment. A nutritious diet is important, but confirmed worm infections should be treated appropriately.
7. What is the most common sign of pinworms?
Night-time itching around the anus is the classic symptom. Some children have no symptoms.
8. Can worms affect a child’s growth?
Significant or persistent soil-transmitted helminth infections can interfere with nutrition and may contribute to impaired physical development.
9. Should the whole family be treated for worms?
This depends on the type of infection. For pinworm, CDC recommends treating the infected person, household members and caregivers at the same time because reinfection is common.
10. Does seeing worms in stool mean the treatment failed?
No. Worms can be passed after treatment as they die or are expelled. The presence or absence of visible worms isn’t enough to determine treatment success.
Final takeaway
Deworming in children is an important part of protecting children from the effects of parasitic worm infections, particularly in areas where these infections are common. But successful worm control involves more than giving medicine.
Parents should watch for symptoms such as night-time anal itching, abdominal discomfort, diarrhoea, poor appetite, poor weight gain, fatigue and signs of nutritional deficiency. At the same time, remember that many of these symptoms can have other causes.
For children living in areas covered by preventive deworming programmes, follow the recommended schedule. In India, the National Health Mission currently conducts the National Deworming Day programme twice a year, targeting children and adolescents aged 1–19 years through schools and Anganwadi centres.
Most importantly, combine appropriate treatment with handwashing, clean food and water, proper sanitation, footwear and good personal hygiene. These everyday measures help reduce the risk of reinfection and support better health, nutrition, school attendance and development.
