Frequently Asked Questions

How can I become dehydrated?

There are many ways your body can become dehydrated, leaving you searching for a way to give your body the water it so desperately needs. Some of the most common causes of hydration are:

 

  • - Diarrhoea
  • - Vomiting
  • - Diabetes
  • - Heatstroke
  • - Sweating from exercise
  • - Too much alcohol
  • - Taking medicines which make you use the bathroom
  • - Having a high temperature

What are the symptoms of dehydration?

Symptoms of dehydration include:

 

  • - Feeling thirsty
  • - Dark yellow and strong-smelling urine
  • - Dizziness
  • - Feeling tired
  • - Dry mouth, lips and eyes

Why does vomiting and diarrhoea cause dehydration?

If you’re ill with a nasty stomach bug, frequent vomiting or diarrhoea can cause you to become dehydrated.

 

This is because your body is losing more fluids than it’s taking in, and it’s also losing essential salts and nutrients.

 

Your body needs water to function properly, so when you’re losing fluids through vomiting or diarrhoea you may start to experience symptoms like feeling thirsty, tired or dizzy.

How do rehydration sachets work?

Rehydration sachets typically contain a formula of salts, glucose and essential minerals to help your body boost its hydration levels and correct electrolyte imbalance.

 

You will usually dissolve them in water to replace fluids after a bout of vomiting or diarrhoea.
