Other Indicators
In addition to these symptoms, people with dehydration might also experience some other conditions. A lack of water would make you feel exhausted even when you are resting. This might be caused by a lower level of blood pressure and reduced energy. Nausea and dizziness can also happen and trigger vomiting, which would make you lose more water and worsen the symptoms. In severe cases, dehydration would result in fainting and lightheadedness when you suddenly stand up. Last but not least, some vision changes might be an indication of this health issue. Insufficient fluids in your eyes would make your vision become blurry due to irritation or dryness. [10]
