Yes, dry mouth can be a symptom of the end of life.
As a person approaches the end of life, especially in their final hours or days, they often experience a decrease in the need for both food and fluids. This is also often accompanied by a state of unconsciousness and mouth breathing. Consequently, the production of saliva diminishes, leading to a dry and uncomfortable mouth, a condition known as xerostomia. As stated in the reference on 14-Jul-2023, "When a person is dying, in their last hours or days of life, they are often require less food and fluids and people are often unconscious and mouth breathing. Less saliva is produced, and the mouth can become dry (xerostomia) and uncomfortable."
Understanding Dry Mouth at End of Life
Dry mouth, or xerostomia, occurs due to a reduced production of saliva. This can be caused by several factors, particularly in the context of end-of-life care:
- Reduced Fluid Intake: As individuals near death, their desire for food and liquids decreases significantly, reducing the fluids available to the body, including those for saliva production.
- Mouth Breathing: Unconsciousness often leads to mouth breathing, which further dries out the oral cavity.
- Medications: Certain medications, which might be administered in palliative care, can also contribute to dry mouth.
- Dehydration: The body’s overall hydration level often diminishes as the end of life approaches, further reducing saliva production.
Managing Dry Mouth at End of Life
While dry mouth can be uncomfortable, it can be managed to improve comfort:
- Frequent Oral Care: Regular moistening of the mouth with swabs or damp cloths.
- Lip Care: Applying lip balm to prevent cracking and dryness.
- Artificial Saliva: Using commercial saliva substitutes as prescribed or recommended by a healthcare professional.
- Ice Chips: Small ice chips can help to keep the mouth moist, provided the individual can handle them.
The Importance of Comfort
Maintaining oral hygiene and addressing dry mouth at the end of life is crucial for overall comfort and dignity. A moist, comfortable mouth can significantly improve a dying person’s quality of life.
