When the body does not have enough water and fluids to carry out normal functions, the consequences can be serious. The Mayo Clinic defines the loss of fluid and inadequate replenishment as dehydration. There are some early signs of dehydration that can signify the need for fluid intake to prevent complications. Some of these symptoms are clearly linked to dehydration, while others may be misattributed to some other ailment. Dehydration is caused by a number of things, including diarrhea, vomiting, fever, excessive sweating and excessive heat exposure.
Thirst
Even mild thirst can be a sign of dehydration. This sensation is the body's natural way of attempting to prevent the serious complications associated with inadequate fluid levels. Severe dehydration can lead to a thirst that is unable to be quenched. Best fluid choices include clear and sugar-free beverages. Avoid caffeine, carbonation and sugar until dehydration has improved.
Mouth Symptoms
Mouth dryness is often an early symptom of dehydration. The tongue and mouth may feel tacky or sticky. Bad breath is caused by mouth dryness and can be another early sign of dehydration.
Urinary Symptoms
When the body's fluid levels are diminished, the urinary output can be impacted. Some individuals may first notice darkened urine that has a strong odor. Eventually, dehydration can lead to a decreased amount of, if any, urination. In infants and children, this can mean very few wet diapers.
Dry Mucous Membranes
The body will conserve any fluids that do exist, which means withholding unnecessary secretions, such as tears. When dehydrated, infants or children may cry, but no tears will fall. The University of Maryland Medical Center points out that even the nose may become dry. Chapped, dry lips can also develop.
Discomfort
A headache or muscle weakness can occur as the result of dehydration. Depending on the level of dehydration, these can be mild or moderate. Rehydration can improve these symptoms, especially with the consumption of sodium-containing beverages, like clear broths. The Mayo Clinic suggests dizziness or lightheadedness can develop. A lack of fluids can lead to sleepiness or unusual tiredness, especially in children.
