Staying Well for 6/1/09

Dehydration (For 6/1/09)
By Genesee County Health Department Staff

Dehydration occurs when the body loses too much fluid and that fluid is not replaced. Diarrhea, vomiting, fever, sweating, or exercise can lead to dehydration. Dehydration can occur at any age, but it is most dangerous for babies, small children, and older adults. These groups should be watched closely for the early symptoms of dehydration. Dehydration can cause minor health problems such as cramps and dizziness. However, it can also lead to shock, which is a life threatening health condition.

Thirst is one symptom of dehydration, but it is not an early warning sign. By the time you feel thirsty, you may already be dehydrated. Other symptoms of dehydration include:

• a dry mouth and sticky saliva.
• producing less urine and the urine is dark yellow.
• having no energy or being easily irritated.
• muscle cramps
• feeling dizzy or light-headed.

The following actions help prevent dehydration:

• Treat illnesses that cause diarrhea, vomiting, or fever. If the sick person begins to have symptoms of dehydration, check with a healthcare provider.
• During hot weather, drink 8 to 10 glasses of fluids. Water is best, but drinks such as Gatorade or Pedialyte help prevent dehydration too.
• Drink extra water before, during, and after exercise.
• Limit drinks that contain caffeine or alcohol, including beer and wine. They make you dehydrate faster.
• Stop working outdoors or exercising if you feel dizzy, lightheaded, or very tired.
• Wear lightweight, light-colored clothing and a light weight hat when you are working or exercising outdoors.
• Don’t intentionally exercise in clothes meant to cause extra sweating.
