Some of the common causes of dry mouth include taking certain medications (antihistamines, blood pressure medications) and overall dehydration. In this video, integrative gastroenterologist Robynne Chutkan, MD, shares some solutions for dry mouth.

Causes of reduced saliva flow, or dry mouth, include certain medical disorders and are a potential side effect of numerous medications (prescribed and over-the-counter). Among them are antihistamines, decongestants, painkillers, high blood pressure medications, muscle relaxants, drugs for urinary incontinence, Parkinson’s disease medications, antidepressants and many others. Drying irritates the soft tissues in the mouth, which can make them inflamed and more susceptible to infection.

Dry mouth is a condition in which salivary production in the mouth is greatly reduced. Besides making you feel thirsty, dry mouth can cause cavities, food intake and tasting problems, promote gum disease and cause mouth pain. For some, this condition can negatively alter a person's quality of life in a profound way.

Medical studies suggest that an age-related decrease in energy production and adenosine triphosphate (ATP) has been suggested to result in impaired salivary secretion. Some cases of dry mouth can be caused by an autoimmune issue called Sjogren's Syndrome. But in many cases, it is unclear what is causing this problem. We do know that the incidence of dry mouth increases as we age, with a particularly high incidence among peri-menopausal women, which suggests that hormonal changes may play a role.
