  • Dehydration occurs when you lose more fluids than you are consuming.
  • Most people make 1 to 3 quarts of urine per day, yet people with diabetes insipidus can make up to 20 quarts of urine per day.
  • When the body is dehydrated, it can struggle to regulate its temperature, which can cause additional fatigue and lethargy.
  • Because alcohol inhibits antidiuretic hormone, it can force liquids out of your body along with essential minerals and electrolytes – this process occurs even faster on an empty stomach.

Reasons you’re dehydrated

  • Although alcohol has no health benefits, many people enjoy drinking beer, wine, or other alcoholic beverages, and there are several ways you can minimize or avoid alcohol dehydration.
  • The subjects still get the initial spike in urine flow after the first drink, but then urine flow dies down.
  • Too much sodium increases fluid loss as your body tries to flush it out.

  • How much water you need to drink is unique to your situation, depending on the amount of energy you use.
  • These effects might not last very long, but that doesn’t make them insignificant.

Since those effects don’t last long, you might not worry much about them, especially if you don’t drink often.
