How This Dehydration Assessment Works
Scientific Methodology
This assessment tool is based on validated clinical research:
- 1Clinical Dehydration Scale (CDS)
Developed by Goldman et al. (2008) and validated for clinical accuracy in assessing dehydration severity.
- 2WHO Guidelines
World Health Organization dehydration assessment criteria, widely used in clinical practice globally.
- 3Weighted Symptom Scoring
Symptoms are weighted based on clinical significance - severe symptoms like confusion or rapid heartbeat receive higher scores than mild symptoms like thirst.
Understanding Dehydration Levels
| Level | Body Water Loss | Typical Symptoms | Action Required |
|---|---|---|---|
| Well Hydrated | 0% | None - pale urine, normal energy | Maintain current intake |
| Mild (1-3%) | 1-3% | Thirst, dark urine, dry mouth | Drink 1-2 glasses water |
| Moderate (3-5%) | 3-5% | Headache, dizziness, fatigue | Rehydrate over 2-4 hours |
| Severe (5%+) | 5%+ | Confusion, rapid heart, no urination | Seek medical attention |
