NF06.2/T66-T78 Post exertional dehydration



Post exertional dehydration is caused by insufficient fluid intake during exercise, which can lead to a decrease in intravascular fluid volume, resulting in a decrease in blood pressure and a decrease in circulating blood volume.


Post exertional dehydration is typically diagnosed based on a physical examination and medical history. Signs and symptoms of dehydration may include extreme thirst, dry mouth, low urine output, dizziness, and fatigue.

Differential diagnosis

Differential diagnosis for post exertional dehydration includes other conditions that can lead to dehydration such as diabetes, heat exhaustion, and kidney disease.


The primary treatment for post exertional dehydration is to replenish fluids and electrolytes. This can be done by drinking plenty of water or sports drinks, and eating foods high in water and electrolytes such as fruits and vegetables.


With appropriate treatment, post exertional dehydration can be effectively managed and reversed. However, it is important to note that dehydration can lead to serious health issues if left untreated, so it is important to seek medical attention if symptoms persist.
