Drugs and ageing are the most common causes of dry mouth. But if you have rheumatoid arthritis (RA) or lupus you’re also at increased risk of Sjogren’s syndrome, an autoimmune disorder whose main symptoms are dry mouth and eyes, said the Arthritis Foundation.
The health site continued: “For years, Sjogren’s was considered a nuisance condition that didn’t cause serious problems.
“It’s now known that it can also affect your joints, kidneys, lungs, skin and cause ongoing fatigue.
“Like other autoimmune diseases, Sjogren’s occurs when inflammation is directed against the body’s own tissues – in this case, the glands that produce moisture in your mouth and eyes.”
