Frequently Asked Questions
How do you know you're dehydrated?
At Honolulu Urgent Care, we often see patients unsure if what they’re feeling is due to dehydration. Here are some common signs to watch for:
- Feeling very thirsty
- Dry mouth or sticky tongue
- Fatigue or low energy
- Dizziness or feeling lightheaded
- Headache that doesn’t ease up
- Dark yellow urine
- Less need to urinate
If you’re noticing two or more of these symptoms, especially in the heat or after exercise, you may be dehydrated. It’s always better to be cautious. Walk in to our clinic — no appointment needed — and a healthcare provider will assess your condition and help you feel better fast.
How long does it take to rehydrate your body?
The time it takes to rehydrate depends on how dehydrated you are and how you’re being treated. Mild dehydration from things like sweating or light illness can often be improved in a few hours with water and electrolytes. For moderate dehydration:
- Oral fluids may help in 2–4 hours
- IV fluids typically work faster — often within 30–60 minutes
To stay hydrated afterward:
- Sip water steadily throughout the day
- Add an electrolyte drink if you’ve lost a lot of fluids
- Monitor urine color — pale yellow is ideal
At our Honolulu walk-in clinic, we’ll help you rehydrate quickly and give you tips to maintain it.
What is the best drink for dehydration?
Water is always the best place to start, but when you’re dealing with dehydration — especially after vomiting, diarrhea, or heat exhaustion — your body also needs electrolytes. Here are good options:
- Oral rehydration solutions (ORS)
- Coconut water
- Sports drinks (look for low sugar)
- Electrolyte-enhanced waters
Avoid drinks with alcohol, caffeine, or too much sugar, as they can make dehydration worse. If you’re not sure what to choose, our physicians can guide you at the clinic. We’ll also offer you fluids that best match your needs based on your symptoms.
What are 5 symptoms of severe dehydration?
Severe dehydration is serious and can become life-threatening if not treated quickly. Here are five warning signs to look for:
- Rapid heartbeat or breathing
- Sunken eyes and dry, wrinkled skin
- Confusion or disorientation
- Very little or no urination
- Fainting or feeling like you might pass out
In infants and young children, watch for:
- No tears when crying
- Dry diapers for several hours
If you or someone else shows these signs, come to Honolulu Urgent Care immediately. If it’s extremely severe, head straight to the emergency room.
When to go to the ER for dehydration?
While our urgent care clinic treats most cases of dehydration, some situations require emergency care. Go to the ER if you or someone you’re with has:
- Confusion or trouble staying awake
- Rapid heartbeat with low blood pressure
- Fainting or near-fainting episodes
- Ongoing vomiting or diarrhea for more than 24 hours
- No urination for 12+ hours
Infants, older adults, and people with chronic health issues are especially at risk. If your symptoms feel overwhelming or you’re unsure, you can still stop by Honolulu Urgent Care for an evaluation. We’ll assess your condition and refer you to the ER if needed.
