What Is Dehydration & Fatigue?
Dehydration & fatigue often go hand in hand. Dehydration happens when your body loses more water than it takes in. As a result, you may feel tired or weak.

Because of this, preventing fatigue from dehydration is important for both body and mind.

Sometimes, urine tests help show if you are dehydrated. Blood tests can also check for changes in salt and mineral levels. In some cases, doctors look for other causes of fatigue to make sure dehydration is the main problem.
