Dehydration

Diagnosis

The doctor will ask about your symptoms and medical history, and perform a physical exam. This will probably include measuring your vital signs. To help provide information for the doctor, keep a diary of:

• your daily weight
• number of times you have vomited or moved your bowels
• your fluid and food intake
• your urine output
• recent travel
• self-treatments you have tried

Tests may include:

• stool sample
  to look for the cause of diarrhea
• urine tests
  to check the concentration of the urine
• blood tests
  to check body fluids and body chemistry
