Dehydration remedies: what to know

Mild fluid loss may improve with water and fluids taken regularly. Oral rehydration solutions contain water and salts in a balance intended to replace losses from vomiting or diarrhoea; follow the packet directions and do not make the mixture stronger. Sports drinks, very sugary drinks and alcohol are not interchangeable with oral rehydration fluid. Dehydration caused by Heat Exhaustion needs cooling as well as fluids. Kidney or heart conditions can change what is safe.

Rest in a cool place and take small sips every few minutes. If nausea settles, increase gradually. Eat light foods when wanted, and replace fluids after sweating or loose stools. Treat the likely trigger: seek advice for ongoing diarrhoea, vomiting, fever or painful urination rather than relying on fluids alone. Avoid salt tablets and unapproved herbal products. A pharmacist or clinician can help choose an oral rehydration product if you take regular medicines.

Seek urgent care for confusion, fainting, severe weakness, inability to swallow, repeated vomiting, very little urine or worsening dizziness. Get prompt advice for dark urine that persists, blood in vomit or stool, severe pain, high fever or signs of Heat Exhaustion. Children, older adults and people with long-term conditions may become unwell quickly.

Ask which fluid suits your symptoms, whether your medicines need review during vomiting or diarrhoea, and how to prevent another episode.
