Risk of Dehydration During a Fever

dehydration-fever

Fever is defined as an elevated body temperature (above 98°F) and can be caused by conditions such as the common cold, influenza, infections (viral and bacterial), or gastroenteritis.

When you experience a fever, you often suffer from increased sweating which can lead to fluid and electrolyte loss. You might also eat or drink less fluid due to feeling unwell.

This combination of reduced fluid intake and sweating can lead to mild dehydration.

Managing Dehydration Due to Fever

It is important to monitor for signs and symptoms of dehydration during a fever.
Please seek further medical advice if*:

  • Fever persists for more than 3 days
  • Temperature rises above 104°F
  • You experience a temperature without sweating
  • Unusual symptoms (such as hallucinations, neck stiffness, skin rash, etc.) occur
  • You are suffering from confusion and drowsiness
  • Your condition is getting progressively worse with time

*This is not an exhaustive list. Please seek medical advice for further information.

As patients with a fever can often have a reduced interest in fluid consumption, small volumes of an oral rehydration solution (Hydralyte) may encourage drinking and help to address mild dehydration.

When managing dehydration in children or the elderly, the use of an oral fluid intake chart may be useful to measure fluid intake and losses.
