The amount of water in the human body ranges from 50-75%. Dehydration occurs when the body loses more water than it gets. When too much fluid is lost, our body loses its ability to function. Severe dehydration can be fatal.
How Do We Lose Water?
We lose water in the form of water vapor when we breathe, and as water when we sweat, urinate, and in stools. Small amounts of salts are also lost in the process.
Severity Of Dehydration
There are 3 states of dehydration: mild, moderate and severe. Mild and moderate states can often be reversed by intake of fluids containing electrolytes. But if not treated, moderate can become a severe state of dehydration and lead to death.
Symptoms of Dehydration
Mild and moderate dehydration signs can include:
- Increased thirst
- Dry mouth
- Tiredness and sleepiness
- Reduced urination
- Dry skin
- Severe constipation
Severe Dehydration will include all the symptoms above in exacerbated version.
- Urine will appear dark yellow or amber, or even not at all
- Lightheadedness and increased dizziness will impair normal functions
- Drops in blood pressure when standing
- Loss of skin elasticity (skin doesn’t bounce back when pinched)
- Rapid heart rate
- Lethargy that can lead to coma
Conditions That Can Lead to Dehydration
Several conditions, if not closely monitored can lead to dehydration
- Heat exposure
So, always think to drink enough to avoid dehydration when having those conditions.
