SYMPTOMS OF DEHYDRATION
Headaches and cramping are common signs of dehydration, as well as tiredness, irritation, discomfort, and hypotension among others. However, these are late signs. Unfortunately, the body hides mild dehydration very well, and it can take hours before you recognize that you are dehydrated.
TYPE OF DEHYDRATION
Dehydration is a condition that results when the body looses more water than it takes in. The imbalance disrupts the usual level of salts (serum sodium levels, commonly known as electrolytes) and sugars present in the blood.
Type of Dehydration
Based on Sodium level as per mEq/liter
When proportionally the same amount of water and sodium is lost from the body and the dehydration does not affect the concentration of sodium in the extracellular fluid, it is called isotonic or iso-osmolar dehydration. Statistically, in most cases (~ 80%) dehydration is of isotonic type.
When dehydration results in a decreased sodium concentration of the extracellular fluids, it is called hyponatremic or hypotonic or hypoosmolar dehydration, a condition in which the body loses a significant quantity of electrolytes along with the excreted fluids.
When dehydration results in an increased sodium concentration of the extracellular fluid, it is called hypernatremic dehydration or hypertonic or hyperosmolar dehydration. Hypernatremia, a frequently encountered electrolyte disorder, is defined as a serum sodium.
