Water - Water deficiency/dehydration/intoxication
3 important questions on Water - Water deficiency/dehydration/intoxication
- How is water lost in the body (normal processes) and what happens when not replaced?
- What is the recommended daily intake?
Lost water must be replaced or you become dehydrated:
- normal perspiration
- breathing
- urination
- feces elimination (caution diarrhea)
RDI
- minimal 1 Liter per day (one quart each day)
- physically active = 2 liter en 36ml (8 oz)
- Thirsty ---> drink water
- normal perspiration
- breathing
- urination
- feces elimination (caution diarrhea)
RDI
- minimal 1 Liter per day (one quart each day)
- physically active = 2 liter en 36ml (8 oz)
- Thirsty ---> drink water
Although water intoxication is uncommon it can occur:
- When can it occur (primary reason)?
- Name the symptoms
- What happens in the body with the excess water and what is its consequence?
- Which role does edema and water retention plat in this and what does it sign?
Can occur
- when kidneys malfunction
Symptoms
- headache
- nausea
- bloating
- low body temperature
- seizures
Excess water
--> dilutes sodium in blood
--> causing swelling of cells
Edema + water retention
- water from plasma flows from circulatory system
--> into extracellular spaces between cells
--> swollen fingers/ankles --> sign poorly hydrated body
- when kidneys malfunction
Symptoms
- headache
- nausea
- bloating
- low body temperature
- seizures
Excess water
--> dilutes sodium in blood
--> causing swelling of cells
Edema + water retention
- water from plasma flows from circulatory system
--> into extracellular spaces between cells
--> swollen fingers/ankles --> sign poorly hydrated body
- What is the first sign of water deficiency and what happens if it is not corrected?
- Name 5 symptoms of dehydration
- Which people are more at risk for this and why?
Thirst is first sign of water deficiency: if not corrected:
- exhaustion
- weakness
- delirium
- death
- kidneys permanently damaged --> in extended state
Symptoms: dehydration
- thirst
- dark-yellow urine
- slight headache
- difficulty concentrating
- cognitive deterioration
People at risk for dehydration:
- elderly people: sense of thirst diminishes over age
- infants/kids: smaller body size: more water per pound than adults
- exhaustion
- weakness
- delirium
- death
- kidneys permanently damaged --> in extended state
Symptoms: dehydration
- thirst
- dark-yellow urine
- slight headache
- difficulty concentrating
- cognitive deterioration
People at risk for dehydration:
- elderly people: sense of thirst diminishes over age
- infants/kids: smaller body size: more water per pound than adults
