Dizziness, headache, nausea, vomiting, diarrhea, and decreasing urine output are all signs of which heat-related condition?

• A. Dehydration
• B. Heat Exhaustion
• C. Heat Stroke
• D. Hypothermia

Answer: (B)

These signs show dehydration from heat exposure presenting as heat exhaustion. Sweating in hot conditions causes fluid and electrolyte losses, which lead to dizziness, headache, nausea, vomiting, and sometimes diarrhea and reduced urine output as the body becomes dehydrated. Heat exhaustion occurs when the body’s cooling mechanisms can’t keep up due to fluid loss and electrolyte imbalance, producing these symptoms without the severe mental changes or extremely high temperature seen in heat stroke. It’s different from hypothermia, which is a drop in body temperature, and from heat stroke, which involves confusion or altered consciousness and very high core temperature. So, heat exhaustion best fits this cluster of symptoms. If needed, rehydrate and cool the person gradually, and seek medical attention if symptoms worsen or don’t improve.
