What could be causing an extremely dry mouth, bad taste, and white film on the tongue with kidney disease?

These are actually recognized symptoms that can come with kidney disease — so you're not imagining it! When kidneys aren't filtering waste properly, toxins can build up in the blood and leak into saliva, causing that unpleasant taste. The white film on the tongue could be a condition called uremic stomatitis, or possibly a fungal infection called oral thrush, both of which are more common in people with kidney disease. Dry mouth is very common with kidney disease — about 3 out of 4 people on dialysis experience it. Some kidney disease medications can also contribute, including:

- Diuretics (water pills)
- Blood pressure medications
- Immunosuppressants
- Corticosteroids Some things that may help with dry mouth at home include:

- Sipping water frequently throughout the day
- Chewing sugar-free gum
- Using saliva substitute products
- Using a humidifier
- Avoiding caffeine and tobacco

It's really important to bring both the white film and the dry mouth to your doctor's and dentist's attention soon. The white coating especially needs to be checked out, as treatment will depend on the cause. Don't tough it out — there are prescription and over-the-counter options that can help!
