Appendicitis is when the appendix (a small thin pouch connected to the large intestine) becomes inflamed.1
Symptoms of appendicitis include a pain that begins in the middle of the tummy that can progresses to the lower left side of the tummy becoming more severe and constant (this is where the appendix is located).
This area may feel tender to the touch. You may also experience loss of appetite, feel sick or have diarrhoea.1
If you have these symptoms seek medical advice from a GP, NHS 111 or in an emergency dial 999; if the appendix bursts this can be life-threatening.
