Does Dehydration Cause Nausea?

All the Signs That Say You Need to Drink More Water

Once you're thirsty, you've already reached the point of dehydration. It's your body literally telling you that it needs more water. Thirst along with extremely yellow pee are two obvious indicators that you need to up your liquid intake. But there are several not-so-clear signs of dehydration that may end up going ignored. For instance, if you're always low on energy and feeling sluggish, it could be due to — you guessed it — dehydration.

And while it's super easy to remedy (just add water), the consequences of long-term dehydration can actually be life-threatening. Severe side effects can even include brain swelling and kidney failure, which are really not worth it, in my opinion.

Here are other signs to watch out for, according to Mayo Clinic:

  • Extreme thirst
  • Nausea
  • Dizziness
  • Dark-colored urine
  • Diarrhea
  • Vomiting
  • Fatigue
  • Less frequent urination
  • Increased urination
  • Fever
  • Excessive sweating
  • Confusion

And if you have any of the following symptoms, it's time to contact your doctor:

  • Diarrhea for 24 hours or more
  • Black or bloody stool
  • Difficulty keeping fluids down
  • Disorientation

In any case where you're urinating more frequently, sweating more, suffering from diarrhea, or vomiting, be sure you're replenishing your body with more fluids to make up for the loss. Otherwise, you'll be stuck in a vicious cycle.
