Dry Mouth and Lips: What you need to know!

Experiencing dry mouth and lips can be more than just a minor discomfort. It could be indicative of underlying issues or simply a response to environmental factors. In this article, we unravel the causes behind dry mouth and lips, the potential problems they pose, and the various solutions to combat these symptoms effectively. 

Understanding Dry Mouth and Lips:

Dry mouth, known medically as xerostomia, occurs when the salivary glands in your mouth don’t produce enough saliva, leading to a dry, uncomfortable feeling. Similarly, dry lips can result from a lack of moisture in the skin on and around the lips. Both conditions can occur simultaneously, affecting your overall comfort and oral health.

Dry Mouth and Lips

Common Causes:

  1. Dehydration:
  2. Medication Side Effects:
    • Certain medications can reduce saliva production or cause dehydration.
  3. Environmental Factors:
    • Dry or windy weather can dry out the lips and mouth.
  4. Mouth Breathing:
    • Breathing through the mouth, especially while sleeping, can dry out oral tissues.
  5. Underlying Health Conditions:
    • Conditions like Sjogren’s syndrome can cause chronic dry mouth and lips.
