Stomach pain in children is a common concern for parents. Children may complain of abdominal pain because of constipation, gas, indigestion, stomach infection, food intolerance, or other medical conditions. In many cases, the pain improves with simple care. However, severe, recurring, or persistent stomach pain may require medical evaluation.

Parents often ask, “Why does my child have stomach pain?”, “What causes abdominal pain in children?”, and “When should I take my child to the doctor for stomach ache?” Understanding the possible causes, associated symptoms, and warning signs can help you decide when to seek medical advice.

What Causes Stomach Pain in Children?

The causes of stomach ache in children range from minor digestive problems to conditions requiring urgent treatment. Common causes include constipation, gas, infections, acid reflux, food intolerance, functional abdominal pain, urinary infections, and appendicitis.

1. Constipation

Constipation is one of the most common causes of stomach pain in children. A child with constipation may have:

• Hard or dry stools
• Fewer bowel movements
• Pain while passing stool
• Bloating
• Stomach cramps
• Stool withholding
• A feeling of incomplete bowel emptying

Abdominal pain often improves after the child passes stool. A low-fibre diet, inadequate water intake, lack of physical activity, changes in routine, and avoiding the toilet can contribute to constipation.

If your child has frequent constipation, painful bowel movements, or stomach pain that improves after passing stool, consult a pediatrician for appropriate treatment.

2. Gas, Bloating, and Indigestion

Gas and indigestion can cause mild stomach pain, abdominal bloating, fullness, burping, or discomfort after meals. Eating too quickly, overeating, drinking fizzy beverages, or consuming foods that are difficult to digest may trigger symptoms.

Gas pain in children usually improves after passing gas or having a bowel movement. If your child frequently complains of gas pain or bloating, a doctor can help identify possible dietary or digestive causes.

3. Stomach Infection or Gastroenteritis

A stomach infection, also called gastroenteritis, may cause:

• Stomach pain or cramps
• Vomiting
• Loose motions or diarrhoea
• Fever
• Nausea
• Poor appetite
• Weakness

Viral gastroenteritis is common in children, but bacterial infections can also cause abdominal pain and diarrhoea. The most important concern during vomiting or diarrhoea is dehydration.

Offer small, frequent sips of fluids. Seek medical help if your child is unable to drink, urinates less than usual, has a dry mouth, appears unusually sleepy, or has persistent vomiting or diarrhoea.

4. Acid Reflux, Acidity, and Gastritis

Some children experience upper stomach pain because of acid reflux, acidity, or gastritis. Symptoms may include:

• Burning pain in the upper abdomen
• Heartburn
• Nausea
• Sour burps
• Regurgitation
• Stomach discomfort after eating
• Pain when lying down soon after meals

Frequent acidity, vomiting, or upper abdominal pain should be assessed by a pediatrician. Do not give acid-reducing medicines to your child without medical advice.

5. Food Intolerance and Food Allergy

Food intolerance can cause stomach pain, gas, bloating, loose stools, or diarrhoea after eating certain foods. Lactose intolerance is a common example. Some children may also react to specific foods because of food allergy or sensitivity.

Parents may notice symptoms after milk, dairy products, wheat, eggs, or other foods. Keep a food and symptom diary and discuss recurring symptoms with a doctor.

If stomach pain is accompanied by swelling of the lips or face, breathing difficulty, hives, or repeated vomiting, seek emergency medical care.

6. Functional Abdominal Pain

Functional abdominal pain is a common cause of recurrent stomach ache in children. In this condition, the child has genuine pain, but tests may not show a structural problem.

Stress, anxiety, school-related concerns, changes in routine, and emotional difficulties can increase abdominal sensitivity. Children may complain of stomach pain before school, exams, travel, or other stressful events.

Functional abdominal pain does not mean the pain is imaginary. A pediatric gastroenterologist can help rule out other causes and recommend suitable dietary, lifestyle, and emotional support.

7. Worm Infection

Worm infection may sometimes cause stomach pain, bloating, changes in bowel habits, poor appetite, itching around the anus, or weight loss. Symptoms can vary depending on the type of parasite.

Deworming medicine should be given only according to a doctor’s advice, especially in young children. A pediatrician may recommend testing or treatment based on symptoms and exposure history.

8. Urinary Tract Infection

A urinary tract infection can sometimes cause lower abdominal pain in children. Other symptoms may include:

• Burning or pain while urinating
• Frequent urination
• Fever
• Bedwetting after being toilet-trained
• Strong-smelling urine
• Back pain
• Vomiting

If your child has stomach pain with fever or urinary symptoms, consult a doctor promptly.

9. Appendicitis and Other Emergency Conditions

Appendicitis can begin with pain around the belly button and later move to the lower right side of the abdomen. The pain may become severe and worsen with movement. Other symptoms can include vomiting, fever, loss of appetite, and abdominal tenderness.

Intestinal obstruction, gallbladder disease, pancreatitis, kidney stones, and other conditions can also cause severe abdominal pain. These problems require urgent medical assessment.

What Symptoms Can Occur With Stomach Pain in Children?

The symptoms accompanying abdominal pain can provide important clues about its possible cause. Depending on the condition, a child may also experience:

• Constipation or diarrhoea
• Vomiting or nausea
• Fever
• Bloating or abdominal swelling
• Poor appetite
• Pain during urination
• Weight loss or poor growth
• Weakness or unusual sleepiness
• Pain related to meals, bowel movements, or stressful situations

A doctor should assess symptoms that are severe, persistent, recurrent, or associated with changes in the child’s general health.

When Should Parents Take a Child to the Doctor for Stomach Pain?

Parents should consult a doctor if their child’s stomach pain is:

• Severe or getting worse
• Recurrent or lasting for several days
• Associated with repeated vomiting
• Associated with blood in the stool or vomit
• Accompanied by persistent fever
• Associated with ongoing diarrhoea
• Causing poor appetite or reduced fluid intake
• Associated with weight loss or poor growth
• Waking the child at night
• Associated with abdominal swelling
• Associated with marked tenderness
• Accompanied by weakness, unusual sleepiness, or dehydration

Seek urgent medical care if your child has sudden severe abdominal pain, repeated vomiting, a swollen or hard abdomen, blood in the stool, difficulty breathing, fainting, severe weakness, or pain that moves to the lower right side of the abdomen.

How Is Recurrent Stomach Pain in Children Evaluated?

When a child has recurring abdominal pain, the doctor may ask about:

• The location and duration of the pain
• The relationship between pain and meals
• Bowel movements and constipation
• Vomiting or diarrhoea
• Fever or urinary symptoms
• Food triggers
• Sleep and school-related symptoms
• Weight loss or poor growth
• Previous illnesses and medications
• Family history of digestive diseases

The doctor may examine the abdomen and recommend tests only when needed. Depending on the symptoms, investigations may include blood tests, stool tests, urine tests, an ultrasound, or other evaluations.

When Should a Child See a Pediatric Gastroenterologist?

If your child’s stomach pain keeps coming back, affects eating or school, causes frequent vomiting or constipation, or is associated with poor weight gain, consult a pediatric gastroenterologist.

• Encourage regular toilet habits
• Avoid overeating and fizzy drinks
