DEHYDRATION Symptoms and Causes

When you're dehydrated, your body doesn't have enough fluid and electrolytes to work properly. An average person on an average day needs about 3 quarts of water. But if you're out in the hot sun or are exercising a lot, you need a lot more than that. You can also become dehydrated if you are vomiting, have diarrhea, or are sweating a lot. People who are elderly, very young, taking certain medications, or have a chronic illness have a greater risk.

Signs of Dehydration in adults include

  • Being thirsty
  • Urinating less often than usual
  • Dark-colored urine
  • Dry skin
  • Feeling tired
  • Dizziness and fainting

Signs of Dehydration in babies and young children include a dry mouth and tongue, crying without tears, no wet diapers for 3 hours or more, a high fever and being unusually sleepy or drowsy.

If you think you're dehydrated, drink small amounts of water over a period of time. Drinking too much all at once can overload your stomach and make you throw up. If you are exercising in the heat and losing a lot of minerals in sweat, sports drinks can be helpful. Avoid any drinks that have caffeine.

DEHYDRATION Clinical Trials and Studies

Treatments might be new drugs or new combinations of drugs, new surgical procedures or devices, or new ways to use existing treatments. The goal of clinical trials is to determine if a new test or treatment works and is safe. Clinical trials can also look at other aspects of care, such as improving the quality of life for people with chronic illnesses. People participate in clinical trials for a variety of reasons. Healthy volunteers say they participate to help others and to contribute to moving science forward. Participants with an illness or disease also participate to help others, but also to possibly receive the newest treatment and to have the additional care and attention from the clinical trial staff.
