What is dehydration?
Dehydration occurs when fluid loss exceeds intake. Causes range from inadequate intake to excessive losses (vomiting, diarrhea, sweating, fever, diabetes). Most mild-to-moderate cases resolve with structured oral rehydration.
Severe dehydration is dangerous and needs IV fluids, especially in infants, elderly, and people with chronic conditions.
Do I have dehydration? Common signs
If most of these describe what you're experiencing, telehealth may be a good next step:
What causes it
Inadequate fluid intake, vomiting, diarrhea, fever, excessive sweating (exercise, hot weather), uncontrolled diabetes, certain medications, alcohol, kidney disease.
Is it contagious?
No (cause may be).
Pedialyte and sports drinks aren't equivalent — Pedialyte and Liquid IV match medical formulations more closely.
Can it be treated online?
Mild to moderate dehydration is well-suited to telehealth. Severe symptoms (no urine for 12+ hours, confusion, low BP, very rapid heart rate, inability to keep fluids down), infants, elderly with significant symptoms — need in-person care with IV fluids.
How dehydration is treated
Oral rehydration: electrolyte solutions (Pedialyte, Liquid IV, oral rehydration salts) most effective. Sports drinks are second-best (too much sugar). Water alone is fine for mild dehydration with food. Ondansetron if vomiting prevents fluid intake. Severe needs IV fluids in clinic, urgent care, or ER.
Self-care while you wait
- Small frequent sips — don't gulp
- Electrolyte solutions preferred
- Avoid alcohol and caffeine
- Cool dark room if heat-related
- Rest
- Salty crackers + electrolyte drink
- Monitor urine color — pale yellow is target
- Replace 1.5x fluid lost (sweating)
How long does it last?
Mild: hours. Moderate: 24 hours with oral rehydration. Severe: requires IV fluids.
Frequently asked questions
How much water do I need daily?
Roughly 64–96 oz total fluid (including food) for most adults. More with exercise, heat, illness. Thirst is reasonable guide for healthy adults.
Sports drinks vs Pedialyte?
Pedialyte has better electrolyte balance for medical rehydration. Sports drinks have more sugar — fine for exercise.
Can I drink too much?
Yes — hyponatremia (low sodium) from drinking excessive water without electrolytes is dangerous, especially during prolonged exercise.
Why dark urine?
Concentrated urine — kidneys conserving water. Goal is pale yellow.
Is coffee dehydrating?
Mild diuretic effect but net hydration is positive. Doesn't cause dehydration in regular coffee drinkers.
