What is right lower quadrant pain?

Pain in the tummy (abdomen) is a common problem in children. The right side of the lower part of the tummy (below the tummy button) is called the right lower quadrant of the abdomen. The main issue when pain is in this area is whether or not the diagnosis is acute appendicitis, but there are many other possible causes.

When pain comes on suddenly it is called 'acute'. Acute right lower quadrant pain may be caused by (see links for further details):

When pain comes on more gradually and is more persistent (chronic) or comes and goes (recurrent), the possible causes of right lower quadrant pain include:

In children common causes of right lower quadrant (RLQ) pain include:

Estreñimiento

  • Very common in children.

  • Means passing hard stools (faeces), with difficulty, less often than normal.

  • May cause RLQ pain but more 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 y intoxicación alimentaria

  • Cause diarrhoea.

  • May also cause the child to be sick (vomit) and have crampy tummy (abdominal) pains.

  • Pain may be anywhere in the tummy.

  • El dolor puede aliviarse por un tiempo cada vez que se pasa algo de diarrea.

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

Intolerancia a la lactosa

  • 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.

Adenitis mesentérica

  • In children with infections such as colds, glands within the tummy commonly become inflamed giving them tummy ache.

  • El niño puede tener otros síntomas de un resfriado, como secreción nasal o dolor de garganta.

See separate leaflet called Mesenteric Adenitis for more information.

Apendicitis

  • In older children, symptoms will be similar to those in adults (see separate leaflet on right lower quadrant pain).

  • Babies may get watery diarrhoea and vomiting.

  • Preschool children may just have vague tummy pains and go off their food.

See separate leaflet called Appendicitis for more information.

Torsión del testículo

  • Occurs when a testicle (testis) twists around in the scrotum.

  • Ocurre en niños y hombres jóvenes, típicamente adolescentes.

  • Es inusual por encima de los 25 años.

  • Severe pain that develops quickly.

  • Puede afectar a cualquiera de los lados.

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

Preguntas frecuentes

Can common childhood illnesses cause right lower quadrant pain?

Yes, infections like colds can lead to glands in the tummy becoming inflamed, causing stomach ache, a condition known as mesenteric adenitis. The child might also have other cold symptoms like a runny nose or a sore throat.

If my child has right lower quadrant pain, does that mean they definitely have appendicitis?

While acute appendicitis is a significant concern when there is pain in the right lower quadrant, it is not the only cause. Many other common conditions can cause similar pain, such as gastroenteritis, urinary tract infection, or even constipation.

My child often gets an upset stomach after drinking milk. Could this be related to right lower quadrant pain?

Yes, if your child experiences bloating, tummy pain, wind, and watery stools after drinking milk, they might have lactose intolerance. This can sometimes happen temporarily after gastroenteritis or some children are born with a tendency to develop it.

What kind of pain might indicate a more serious condition like a twisted testicle in boys?

A twisted testicle (torsion of the testicle) causes severe pain that develops quickly. It typically affects boys and young men, especially teenagers, and can occur on either side.

Can constipation cause pain in the right lower quadrant?

Constipation, which means passing hard stools with difficulty and less often than normal, can indeed cause pain in the right lower quadrant. However, it more commonly causes pain on the left side, over the last part of the colon.
