What Causes a Dry Mouth | Dr Sanjeev Mohanty | Ent Surgeon

Updated: Nov 22, 2021

In itself, a dry mouth is not a disease and may be due to something as simple as cigarette smoking or constant breathing through the mouth, but can also often be a result of other more serious underlying conditions or other external factors. Several systemic diseases are known to present with xerostomia as a symptom.

A significant one is an autoimmune disease called Sjögren’s syndrome. Other conditions associated with xerostomia include hypertension, asthma, diabetes, hypothyroidism, rheumatic diseases, and eating disorders. Certain medications can contribute to low saliva production and a dry mouth, too, known as xerogenic medications. These can be either over-the-counter or prescription medications, such as anti-psychotics and anti-depressants (particularly those from the category of selective serotonin reuptake inhibitors), oral diabetes medications, diuretics used to treat hypertension, and antihistamines or decongestants commonly used for allergies and colds. There are also medical procedures, such as radiation therapy to the head and neck area, or chemotherapy, that can induce hyposalivation and xerostomia, primarily through damage to the salivary glands as an unavoidable side effect.
