What Causes Dry Mouth?
Dry mouth, or xerostomia, occurs when the salivary glands in the mouth don't produce enough saliva. This can cause uncomfortable symptoms, such as an inability to swallow, a dry or sticky feeling in the mouth, and a bad taste. Dry mouth is often caused by medications, certain medical conditions, or dehydration.
Medications
Many different types of medications can cause dry mouth, including decongestants, antihistamines, and antidepressants. Some medicines used to treat high blood pressure, as well as drugs used to treat Parkinson's disease, can also cause dry mouth.
Medical Conditions
Certain medical conditions can cause dry mouth, such as Sjogren's syndrome, diabetes, and HIV. Additionally, radiation therapy can cause dry mouth in some people.
Dehydration
A lack of fluids can cause dry mouth. Dehydration can be caused by not drinking enough water, exercising in hot weather, or being ill with vomiting or diarrhea.
Treating and Preventing Dry Mouth
There are several ways to treat and prevent dry mouth. Drinking plenty of fluids, avoiding foods that cause dehydration, and avoiding certain medications can help. Additionally, using a saliva substitute, such as a mouthwash or spray, may help. Consult a doctor for more severe cases.
