What is Numark Rehydration Treatment?

Numark Rehydration Treatment sachets are a remedy for dehydration caused by diarrhoea or vomiting. It’s ideal for adults and children, helping to replace the fluids you’ve lost and restoring the balance of salts in your body. These sachets are blackcurrant flavoured, dissolving in water to make a delicious drink that will help you to stay hydrated until your diarrhoea has passed.


Why do I have diarrhoea?

Diarrhoea usually happens when you have a stomach bug, or gastroenteritis. This can be caused by a virus, such as norovirus, or food poisoning. When you have diarrhoea, it means that your bowel can’t absorb fluid or is secreting extra fluid, which is then passed from the body. Some of the other causes of diarrhoea include:

  • IBS
  • Inflammatory bowel disease
  • Coeliac disease
  • Diverticular disease
  • Drinking too much alcohol
  • Food allergies or intolerances
  • Some medications


How will Numark Rehydration Sachets keep me from becoming dehydrated?

Numark Rehydration Sachets work by helping your body to replace the fluids and salts it can lose when you have diarrhoea. These sachets are a type of treatment called oral rehydration solution (ORS), and they’re ideal for those who have lost fluids and are at risk of dehydration when they’re suffering with diarrhoea or vomiting.


How to use Numark Rehydration Treatment
