Diabetes and Dry Mouth in Korea

Diabetes and Dry Mouth in Korea

Overview

Diabetes and dry mouth (xerostomia) are closely linked, as high blood sugar levels can reduce saliva production and cause dehydration. Many people with diabetes experience persistent dryness in the mouth, difficulty swallowing, bad breath, or increased dental problems.

This symptom is not only uncomfortable but also increases the risk of oral infections, gum disease, and tooth decay. Managing dry mouth is an important part of overall diabetes care.

In Korea, patients with diabetes and dry mouth can access specialized endocrinology and dental clinics, where modern diabetes management and oral health treatments are combined for comprehensive care.


Key Facts

Highlights:

➡️ Diabetes is a common cause of chronic dry mouth.
➡️ Caused by high blood sugar, dehydration, or medication side effects.
➡️ May lead to dental problems, oral infections, and difficulty eating.
➡️ Good blood sugar control helps reduce dry mouth symptoms.
➡️ Specialized oral and diabetes care is available in Korea.


What is Diabetes-Related Dry Mouth?

Dry mouth in people with diabetes occurs when salivary glands don’t produce enough saliva, often due to poorly controlled blood sugar.

Key Features:

  • Constant feeling of dryness in the mouth
  • Difficulty speaking or swallowing
  • Cracked lips or mouth sores
  • Sticky, thick saliva
  • Increased thirst

  • Oral fungal infections (thrush)

Highlights:

➡️ Increases risk of dental and oral complications.


What Causes / Possible Causes?

Highlights:

➡️ High blood sugar → causes dehydration and reduced saliva production.
➡️ Diabetes medications (some blood pressure or nerve drugs used in diabetics can cause dry mouth).
➡️ Nerve damage (diabetic neuropathy) affecting salivary glands.
➡️ Mouth breathing due to nasal congestion or sleep apnea (common in diabetes).
➡️ Dehydration from excessive urination (polyuria).

➡️ Persistent dry mouth despite good hydration.
