Thick Saliva

What is it?

Thick saliva refers to the condition where the saliva becomes unusually thick and sticky, which can make swallowing difficult and cause discomfort in the mouth. This can be caused by various issues such as dehydration, salivary gland disorders, infections, or side effects from certain medications.

Causes of Thick Saliva

• Dehydration. A lack of fluid in the body can reduce saliva production and increase its viscosity.
• Medications. Certain medications, such as antihistamines, antidepressants, or diuretics, can cause dry mouth and thick saliva.
• Oral Infections. Infections, such as stomatitis or candidiasis, can alter the composition of saliva, making it thicker.
• Salivary Gland Disorders. Chronic disorders of the salivary glands, such as Sjögren’s syndrome, can reduce saliva production and increase its viscosity.
• Diabetes. Uncontrolled blood sugar levels can lead to thicker saliva.
• Dry Mouth (Xerostomia). A decrease in saliva production can cause a sensation of dryness and thickness in the mouth.
• Allergies. Allergic reactions can also cause changes in saliva secretion, making it thicker.

When to See a Doctor?

• If thick saliva is accompanied by pain, inflammation, or discomfort in the mouth.
• If the condition persists for an extended period or worsens.
• If you notice other symptoms, such as thirst, dry mouth, difficulty swallowing, or speaking.
• If thick saliva is accompanied by a bad odor or mouth pain.

Diagnosis and Treatment

• Physical Examination and History. The doctor will perform an examination and gather information about symptoms to understand possible causes of thick saliva.
• Blood Tests. Tests to check blood sugar levels and other factors that may affect saliva viscosity.
• Salivary Gland Function Assessment. Tests may be conducted to assess the function of the salivary glands and detect conditions such as Sjögren’s syndrome.
• Treatment of the Underlying Condition. Depending on the cause, the doctor may prescribe medications to treat infections, restore salivary gland function, or improve hydration.
• Moisturizing Agents. Moisturizing products or saliva substitutes may be recommended to reduce discomfort.
