Symptoms

Many people who develop chronic kidney disease do not have symptoms at first. This is known as the "silent" phase of the disease.

As your kidney function gets worse, you may:

• Urinate less than normal.
• Have swelling from fluid buildup in your tissues (edema).
• Feel very tired.
• Lose your appetite or have an unexpected weight loss.
• Feel nauseated or vomit.
• Be either very sleepy or unable to sleep.
• Have headaches or trouble thinking straight.
