Why Dry Mouth
What is Xerostomia?
Doctors call a chronic lack of saliva xerostomia. Its not the same as simply feeling thirsty; its when your salivary glands dont produce enough fluid, leaving your tongue and gums stuck in a cottonlike state.
How Diabetes Triggers It
High bloodsugar levels pull water out of your cells, which means you pee more and lose fluids faster. Your kidneys work overtime, and the result is dehydration that hits your mouth first. Studies from the show a clear link between uncontrolled glucose and reduced saliva flow.
Low Blood Sugar Too?
Its not just hyperglycemia. When your blood sugar dips, the body releases adrenalinea fightorflight hormonethat also suppresses saliva. So, both ends of the glucose spectrum can leave you with that parched feeling.
Medications That Contribute
Many diabetes medicines have dryness as a sideeffect. Metformin, for instance, is notorious for causing a dry mouth at night. If youre on an SGLT2 inhibitor, you might notice extra nocturnal thirst because those drugs push glucose (and water) out through urine.
