Recognizing Dehydration Signs in Adults and Children
In adults, early signs of dehydration include thirst, dark urine, and mild lightheadedness. In babies and toddlers, watch for dry diapers (no urination for 6 hours), dry mouth, lack of tears when crying, lethargy, or a sunken soft spot (fontanelle).
When to Seek Urgent Care
Severe dehydration can cause organ strain, low blood volume shock, or electrolyte imbalances. If you or a child experience confusion, fainting, inability to keep liquids down, or complete lack of urination, seek emergency care immediately.
When to Seek Urgent Medical Attention
- Severe confusion, lethargy, or difficulty waking a dehydrated person.
- Complete lack of urination for 8 hours in adults, or 6 hours in infants.
- Inability to keep liquids down due to constant vomiting or diarrhea.
Frequently Asked Questions
Dehydration occurs when your body loses more fluids and electrolytes than you take in. Common causes include vomiting, diarrhea, high fever, excessive sweating, or inadequate fluid intake.
Manage mild dehydration by drinking small, frequent sips of water or oral rehydration solutions (which contain balanced water, salts, and sugar). Avoid sugary drinks or sodas.
