It is often quite difficult for young children to show us where their pain is. Because of this, almost any problem in the abdomen can cause tummy pain. However, knowing "where it hurts most", can give us good clues as to the culprit. .
What are the most common causes of left-side abdominal pain in children?
In children common causes of left-sided tummy pain include:
- 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) where stools can get stuck.
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.
- Leads to bloating, tummy pain, wind and watery stools after drinking milk or any food containing dairy.
- Lactose intolerance can sometimes occur for a while after a bout of vomiting or diarrhoea. The condition gets better when the infection is over and the gut lining heals.
- Some people are born with a tendency to develop it.
- In children with infections such as colds, glands within the tummy commonly become inflamed giving them tummy ache. These glands are similar to the ones in the neck that get bigger or painful when we have sore throats.
- The child may have other symptoms of a cold, such as a runny nose or a sore throat.
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.
- If this occurs, you need to go to the emergency department immediately.
- Coeliac disease is caused by a reaction of the gut to gluten. Gluten is found in many foods such as pasta and bread.
- it can cause poor growth or weight loss.
- 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.
