Full Answer

Individuals who are dehydrated may notice that their tongue swells and the color of their urine is deep yellow or amber, explains WebMD. Some patients experience sluggishness that can result in fainting when dehydrated.

Patients who are dehydrated should consult with a physician when experiencing constant or increased vomiting for more than 24 hours or a fever over 101 degrees Fahrenheit, according to WebMD. Medical attention is also necessary when dehydrated individuals have diarrhea for more than two days, experience weight loss and decreased urine production and become extremely weak or confused.

Emergency care is necessary when people have difficulty breathing, chest or abdominal pain, headaches and sluggishness and begin having seizures, explains WebMD. A lack of urination within 12 hours or a fever higher than 103 degrees also indicates a medical emergency.

Dehydration occurs in normal human beings when they are not able to replenish fluid loss, explains WebMD. Individuals who have a fever, an infection that causes vomiting and diarrhea, or diseases such as diabetes are more susceptible to dehydration. Heat exposure and too much exercise can also cause dehydration.
