What Diseases Cause Dry Mouth?

2 min read

Diabetes Can Cause a Constantly Dry Mouth

Diabetes is one condition worth knowing about. High blood sugar can lead to increased urination, which pulls more fluid from the body. You may then feel thirsty and notice that your mouth feels sticky or unusually dry.

And sometimes the dry mouth is one of the signs that prompts someone to get checked for diabetes. It doesn’t prove you have the disease, though. Other symptoms matter too.

Sjögren’s Syndrome Is Closely Linked to Dry Mouth

Sjögren’s syndrome deserves special attention because dryness is one of its main features. It’s an autoimmune disease in which the immune system attacks glands that produce moisture, including the salivary glands.

Your mouth can feel painfully dry. Swallowing crackers suddenly becomes a chore. Some people also develop dry eyes, because the tear glands can be affected too.

Other Diseases That May Be Behind It

• Thyroid problems can sometimes be involved, especially when other changes in energy or body function show up alongside the dryness.

• Kidney disease may lead to changes in fluid balance. And that can leave your mouth feeling much drier than usual.

• HIV infection has been associated with dry mouth, although many other factors can contribute to the symptom.

• Anxiety itself isn’t a disease, but ongoing stress can reduce saliva flow. That cotton-mouth feeling before a big presentation is a familiar example.

Mouth Problems Can Follow Too

Saliva does more work than people give it credit for. It helps keep the mouth comfortable and protects teeth from acids. So when saliva stays low, tooth decay becomes easier to develop and the mouth can feel irritated.

Priya noticed this after several weeks of constantly sipping water at her desk. She also stopped reopening the same five tabs every morning just to remind herself to drink. The dryness kept coming back anyway, which finally convinced her to mention it at a dental visit.

When Dry Mouth Deserves Attention

If your mouth has been dry for weeks, don’t just accept it as your new normal. A dentist or doctor can look for an underlying reason and review medicines that may be affecting saliva.
