Chronic kidney disease and polycystic kidney disease often go undiagnosed and are allowed to progress because the signs and symptoms are so subtle. There are 5 key kidney disease symptoms.
1. Changes in Urination. Because your kidneys are tasked with making urine, and thereby eliminating waste, any changes in the frequency, color, or appearance of urine should be taken seriously. Some common types of changes include:
Urinating more frequently during the night or in greater amounts
Urinating less often or in smaller amounts
Having foamy or bubbly urine or blood in your urine
2. Swelling. If your kidneys are unable to remove extra fluid from your body, you will likely experience swelling in your legs, ankles, feet, face, or hands.
3. Skin Rash / Itching. If your kidneys are unable to remove waste from the bloodstream, the buildup can cause rashes and severe itching.
4. Leg, Back or Side Pain. Kidney problems can lead to pain in the back, side or even in the leg. Kidney cysts (large, fluid-filled sacs) resulting from polycystic kidney disease that form on kidneys and occasionally on the liver can also cause back and leg pain.
5. Metallic Taste in Mouth/Ammonia Breath. When waste builds up in the bloodstream, it can cause bad breath, a metallic taste in the mouth, and affect how food tastes. You may also have a change in appetite that results in weight loss.
