Mild Dehydration

When the body does not get enough water to fulfill its needs, it becomes dehydrated. The dehydration may be mild, moderate, or severe depending upon the amount of fluid deficiency.

Causes of dehydration

Some common causes of mild dehydration are as follows:

  • Excessive sweating 
  • Diarrhea and vomiting 
  • Some medical conditions that cause excessive peeing, such as diabetes mellitus
  • Brain abnormalities that keep a person from getting thirsty
  • Forgetting to drink water due to a busy schedule.
  • Lack of access to water
  • Medications like diuretics
  • Fever


The most common symptoms of mild dehydration are as follows:

  • Thirst 
  • Excessive dry mouth and throat
  • Highly concentrated urine (deep yellow)
  • Headache
  • Muscle pain or myalgia 
  • In children, crying without tears
  • Lack of energy
  • Low blood pressure


If dehydration is severe, feelings of thirst may be reduced and blood pressure may drop, causing dizziness or fainting, especially when standing up (a condition called orthostatic hypotension). If dehydration persists, shock and severe damage to internal organs, such as the kidneys, liver, and brain can occur. 

Brain cells are particularly sensitive to severe levels of dehydration. As a result, confusion is one of the best indicators of the severity of dehydration. Extremely severe dehydration can lead to coma.


Mild dehydration can lead to complications, so prompt medical treatment is required. Your medical provider may provide the following treatment plans for dehydration:

  • Fluid intake is the most common. Drink fluids and electrolytes if there is no nausea and vomiting. If drinking is not possible, fluids may be given intravenously.
  • Remove yourself from a hot environment and cool down the body either by air-conditioning or with cool water.
  • In case of fever, over the counter acetaminophen can bring down temperature
  • Remove clothes or shoes to lower body temperature.

Treatment should also be directed at the cause of dehydration. For example, if there is nausea and vomiting or diarrhea, medications may be needed to control or stop these issues.
