About 1 out of every 10 people (10%) have diarrhoea during their illness. You need to know what is normal for you when deciding whether you have diarrhoea or not.
Common signs and symptoms of diarrhoea
Generally, diarrhoea means:
- an increase in the number of bowel movements you have each day
- an increase in the amount (volume) of poo (stools or faeces) you have in a day
- a change in the way your poo looks (it goes from solid to soft or watery)
Other symptoms you may notice are:
- cramping pains in your tummy (abdomen)
- feeling sick
- needing to get to the toilet urgently
- a bloated feeling in the tummy
If you have a colostomy or ileostomy and you are emptying your stoma bag more often than normal, it may be a sign that you have diarrhoea.
Symptoms of severe diarrhoea
Severe diarrhoea can make you lose a lot of fluids (dehydration). This can make you very ill if you don't have treatment. You might have a serious infection that is making your diarrhoea worse.
So it’s important that you see your doctor if you have any of the following symptoms:
- a high temperature (fever) or chills
- signs of dehydration such as feeling very thirsty, a rapid heart beat, feeling or being sick, and dark urine
- blood or mucus in your poo
- severe cramping and tummy pain
When to contact your doctor or nurse
Sometimes it can be hard to know when to call your doctor or nurse because you don’t want to bother them. You may feel embarrassed about talking about diarrhoea.
Tell your doctor or nurse as soon as you have the first signs of diarrhoea. They will understand and want to help. They can advise you on how to manage your diarrhoea and may recommend some medicines.
