Signs and Symptoms of Dehydration

Signs and symptoms of dehydration, like those of many other treatable health conditions, can be virtually identical to senile dementia symptoms, age dementia symptoms and Alzheimers symptoms. Correcting dehydration can allow an older person to return to a full and normal life.

The most common signs and symptoms of dehydration include persistent fatigue, lethargy, muscle weakness or cramps, headaches, dizziness, nausea, forgetfulness, confusion, deep rapid breathing, or an increased heart rate. Dehydration is a very serious condition, more than most people realize. Since seniors often have a reduced sense of thirst, dehydration is one of the most frequent causes of hospitalization after age 65.

Other less common signs and symptoms of dehydration can include:

Excessive loss of fluid through vomiting, urinating, stools or sweating
Poor intake of fluids, "can't keep anything down"
Sunken eyes
Dry or sticky mucous membranes in the mouth
Skin that lacks its normal elasticity and sags back into position slowly when pinched up into a fold
Decreased or absent urine output
Decreased tears

If you or a loved one have any of these symptoms, and they are persistent for 2 to 3 days, call a doctor immediately — or go to a hospital emergency room. If left untreated, dehydration can quickly cause severe problems, even death.

— How to avoid dehydration —

Almost everyone gets about half their daily water requirement from solid foods and fruit and vegetable juices. But seniors often have a reduced sense of thirst and a reduced appetite. Here's the water content (by weight) of a variety of fruits and vegetables. Include the ones with the highest water content in meals or serve as snacks to help avoid dehydration.
