What is a swallowed object?

A swallowed object usually refers to any item that should not be swallowed. Healthcare professionals may call it an 'ingested foreign body'.

Sometimes people swallow non-food items that can be dangerous.

Some commonly swallowed objects are:

• coins
• small toys
• household objects

While most swallowed objects can pass through your body without a problem, some need to be removed. This is because they can cause significant harm or even death.

Some objects can be especially dangerous if they are swallowed, such as:

• magnets — especially 2 or more
• button batteries — which can burn through the lining of your oesophagus (food pipe), causing serious injury or death
• water beads

Water beads, or super-absorbent polymer balls, can expand up to 400 times their original size when placed in liquid. These toys are also called jelly beads, water balls or fairy beads. If you think someone has swallowed a water bead, seek medical attention straight away.

If you need to see your doctor but cannot wait for an appointment, you may be able to get treatment at a Medicare Urgent Care Clinic. Use the Service Finder to find your nearest one.

Button batteries and magnets need to be removed immediately to avoid serious complications, which can be life-threatening.

What symptoms are related to a swallowed object?

Symptoms can differ depending on what object you've swallowed and if the object becomes stuck. A child often won't have any symptoms when they have swallowed an object.

Objects can sometimes get stuck in your oesophagus, which can cause:

• drooling
• coughing or wheezing
• pain in the neck or chest
• difficulty swallowing food

If an object becomes stuck in your stomach or bowel, this may cause:

• vomiting (being sick)
• abdominal (tummy) pain
• blood in your vomit
• blood in your stool (poo)
• fever

If you or your child is coughing or having difficulty breathing, the object may be stuck in the airway or lungs.

Why would someone swallow an object?

One of the ways babies and young children learn about the world is by putting things in their mouths.

Children at highest risk of swallowing an object:

• are aged 6 months to 3 years
• have older brothers or sisters

Children can also be at higher risk of swallowing an object if they have:

• pica (a condition where they eat non-food items)
• an intellectual disability

It's important to make your home safe so that your child can't put something dangerous in their mouth.

Self-harm

Some people may swallow objects deliberately to harm or injure themselves. If you have done this, you should know you are not alone and help is available.

How is a swallowed object diagnosed?

Your doctor will ask you what object was swallowed and when this happened.

They may do an x-ray if the object is made of a material that will show up on an x-ray.

When should I see my doctor?

If you have swallowed a foreign object other than a magnet or battery and have symptoms, you should see a doctor.

You don't need to see a doctor if you have swallowed a harmless object and have no symptoms. Watch for symptoms over the next couple of days, and seek medical advice if you develop pain, vomiting or trouble swallowing.

When should I get emergency care?

Call triple zero (000) and ask for an ambulance, or go to the nearest emergency department, if you have:

• swallowed a button battery or magnet
• swallowed a large object
• swallowed a sharp object
• tried to harm yourself

You should also call triple zero (000) and ask for an ambulance if you notice symptoms such as:

• trouble breathing
• choking or coughing when eating or drinking
• severe vomiting
• gastrointestinal (GI) bleeding (blood in your vomit or poo)
• pain in your chest or neck
• confusion or loss of consciousness

What should I do while waiting for the ambulance?

Do not eat or drink anything until you have spoken to a doctor.

Do not try to vomit, as this could cause choking or block your airway.

How is a swallowed object treated?

Depending on what object was swallowed and where it is in your digestive system, the object may need to be removed.

Objects in the oesophagus often need to be removed, depending on the symptoms.

Most objects in the stomach or bowel will pass through on their own.

Button batteries and magnets need to be removed immediately.

Most objects can be removed using an endoscope (a thin, flexible tube with a light and camera at the tip). The endoscope can be used to find and remove the object.

Sometimes surgery is needed to remove a swallowed object.

Self-care at home

If you swallow a foreign object that is not one of the dangerous objects listed above and have no symptoms, you may not need to have the object removed. There is no need to look in your faeces (poo) to find the swallowed object.

How do you stop children from swallowing objects?

Keep all small objects away from young children. Small objects that can be swallowed include:

• coins
• pins
• magnets
• small toys
• button batteries

Also, make sure that all remote controls and toys that contain button batteries are kept out of reach.

What are the complications from swallowed objects?

Complications from swallowed objects can include:

• blockage of your oesophagus or bowel
• a tear in your oesophagus
• erosion (a hole) in your digestive system
• weight loss due to feeding problems
