If choking occurs, head to the A&E department where a doctor can remove the obstruction.
Choking may occur when food gets stuck in your trachea (windpipe). Food can also get stuck in your oesophagus (food pipe).

When food gets stuck in your food pipe
What happens when a foreign object gets stuck in your throat or food pipe?
Symptoms
- Pain when swallowing
- Difficulty swallowing (including saliva)
- Discomfort
- Breathing difficulties
Dangers
- Throat injuries from bones and hard objects
What should you do?
- Drink water to try moving it down (if not bones or hard objects)
- Do not attempt to remove bones and hard objects by yourself as they may injure the throat
- Head to the A&E department where a doctor can remove the obstruction
- Specialised equipment may be needed to remove food stuck deep in the throat
Choking foods
Some items that may get stuck in the throat (potentially everything!) include:
- Small fish bones
- Plant fibres
- Chicken bones
Other less common items include:
- Hot dog
- Hard candy
- Chewing gum
- Nuts and seeds
- Chunks of meat or cheese
- Whole grapes
- Popcorn
- Chunks of peanut butter
- Raw vegetables
- Raisins
Common reasons why people choke
- Talking or laughing while chewing and swallowing
- Eating while running (mostly kids) = food may be inhaled with deep breaths
- Alcohol impairs the swallowing mechanism and gag reflex
- Big bites and improper swallowing
- Small foods like nuts can go into the windpipe by mistake
- Advanced age may weaken the gag reflex
- Diseases like Parkinson’s may disrupt the swallowing mechanism
