What is Dry Mouth?
Dry mouth, also called xerostomia, is a condition in which your salivary glands do not produce enough saliva to keep your mouth moist.
There can be various causes due to which your salivary glands do not work properly, and one of the most common causes is diabetes.
What is the Relationship Between Diabetes and Dry Mouth?
Diabetes mellitus is a chronic condition that affects your body's ability to produce or use a hormone called insulin, resulting in high blood glucose levels.
Type 1 Diabetes is an autoimmune disorder, where your immune system mistakenly attacks and destroys the β-cells in your pancreas that are responsible for producing insulin. Type 2 Diabetes is a metabolic disorder characterised by insulin resistance in your cells and tissues, i.e. your cells are not able to utilise the insulin produced by your pancreas, which results in the glucose remaining in your blood.
The exact reason why diabetes causes dry mouth is still unclear. However, it could be due to various reasons as listed below:
- Dehydration: In diabetes, your kidneys continue to produce more urine to remove the excess glucose from your body. This results in frequent urination (polyuria), and dehydration, causing symptoms such as increased thirst and dry mouth.
- Medication: Dry mouth can also be a side effect of some medications used to manage diabetes.
- Hyperglycemia: According to some studies, the high blood glucose (sugar) levels in diabetes can alter the functioning of salivary glands, leading to reduced saliva production and dry mouth.
- Kidney Conditions: Consistently high blood glucose levels can lead to kidney disease, which may cause dry mouth.
What are the Symptoms of Dry Mouth?
Dry mouth can cause the following symptoms:
- Bad breath
- A rough and dry tongue
- Cracked lips
- Dryness or stickiness in your mouth
- Difficulty in chewing and swallowing food
- A changed sense of taste
- Wider space in teeth
- Loose teeth
- Thick, sticky spit
- Burning sensation in your mouth and throat
- Trouble talking
What are the Complications of Dry Mouth?
Your saliva plays a crucial role in your oral health. The enzymes in saliva help in breaking down food, controlling oral bacterial growth, and removing acid and food particles from your teeth and gums.
The absence of saliva and dry mouth may lead to oral complications such as:
- Plaque buildup
- Tooth decay
- Gum disease
- Oral infection
- Thrush or oral candidiasis, a fungal infection in the mouth
- Poor nutrition due to difficulty in swallowing food
How to Treat Dry Mouth?
The best way to treat dry mouth caused by diabetes is to keep your blood sugar levels in check and your diabetes under control. The symptoms of dry mouth can also be controlled by the following steps:
- Drink plenty of water and unsweetened fluids throughout the day.
- Avoid caffeinated drinks like coffee, tea, and some sodas as caffeine can lead to dry mouth.
- Avoid smoking and consuming alcohol as they can also lead to dryness of the mouth.
- Chew sugar-free gum as it can help in the production of saliva.
- Drink water while having meals as it moistens the oral cavity and helps in swallowing your food.
- Use a lip balm if your lips are cracked.
- Use a humidifier while you sleep at night as it can add moisture to the air you breathe.
- If a medication is the cause of dry mouth, you can discuss with your doctor about changing the medication or adjusting its dosage.
- Ask your doctor about using over-the-counter saliva substitutes that contain xylitol.
- Take care of your oral health by brushing your teeth twice daily, flossing, and visiting the dentist regularly.
