The problem of dry mouth, or xerostomia, often occurs due to dehydration, stress or a cold. However, if the unpleasant feeling haunts you constantly, it can be a sign of dangerous diseases. As the Daily Mail writes, British doctor Philippa Kay explained that chronic dry mouth is often associated with serious disorders of the body.
Xerostomia occurs when the salivary glands produce too little saliva. This makes it difficult to swallow, speak, alters the sense of taste, and increases the risk of oral infections.
The most common causes of dry mouth
Medication side effects.
Antidepressants, antihistamines, antihypertensives, muscle relaxants, and urinary incontinence medications often cause xerostomia. If a side effect is suspected, doctors advise discussing a medication change or dose adjustment.
Aggressive therapy:
Radiation therapy and chemotherapy can temporarily damage the salivary glands. The condition usually improves after treatment is complete, and patients are recommended artificial saliva substitute sprays or gels.
Systemic diseases that dryness may signal
Persistent xerostomia can be a sign of serious chronic diseases:
-
Sjögren's syndrome.
An autoimmune disease that affects the glands that produce saliva and tears. Requires consultation with a rheumatologist and special therapy. -
Diabetes:
High blood sugar levels can cause dehydration, which can cause dry mouth. Treating the underlying condition often helps resolve the symptom. -
Parkinson's disease.
Affects the nervous system, and some Parkinson's medications can also cause dryness. Patients are advised to stimulate saliva production by chewing sugar-free gum and lozenges.
When to see a doctor
Philippa Kay emphasizes: if dry mouth does not go away and is not associated with temporary factors, this is a reason to consult a family doctor. Xerostomia can be the first symptom of diseases that require early diagnosis and treatment.
