What are the most common causes of left lower quadrant pain in children?

In young children it is often quite difficult for them to show exactly where the pain is. If this is the case, the field of options widens to almost any cause of tummy ache (abdominal pain). In children common causes of left lower quadrant (LLQ) pain include:

Constipation

  • Very common in children.
  • Means passing hard stools (faeces), with difficulty, less often than normal.
  • Commonly causes pain on the left, over the last part of the colon (descending colon).

See separate leaflet called Constipation in Children for more information.

Gastroenteritis and food poisoning

  • Cause diarrhoea.
  • May also cause the child to be sick (vomit) and have crampy tummy (abdominal) pains.
  • Pain may be anywhere in the tummy.
  • Pain may ease for a while each time some diarrhoea is passed.

See separate leaflets called Gastroenteritis in Children and Food Poisoning in Children for more information.

Lactose intolerance

  • Leads to bloating, tummy pain, wind and watery stools after drinking milk.
  • Lactose intolerance can sometimes occur for a while after gastroenteritis. The condition gets better when the infection is over and the gut lining heals.
  • Some people are born with a tendency to develop it.

See separate leaflet called Lactose Intolerance for more information.

Mesenteric adenitis

  • In children with infections such as colds, glands within the tummy commonly become inflamed giving them tummy ache.
  • The child may have other symptoms of a cold, such as a runny nose or a sore throat.

See separate leaflet called Mesenteric Adenitis for more information.

Torsion of the testicle

  • Occurs when a testicle (testis) twists around in the scrotum.
  • It occurs in boys and young men, typically teenage boys.
  • It is unusual over the age of 25 years.
  • Severe pain develops quickly.
  • It can affect either side.

See separate leaflet called Torsion of the Testis for more information.

Coeliac disease

  • Coeliac disease is caused by a reaction of the gut to gluten. Gluten is found in many foods.
  • it can cause poor growth
  • Stools may be pale, smelly and difficult to flush away.
  • Pain doesn't always occur but can be anywhere in the tummy. It tends to come and go.

See separate leaflet called Coeliac Disease for more information.
