As we all know in diabetes there are frequent changes in the blood sugar level. It’s very hard to keep blood sugar levels normal all the time and no one can manage it perfectly. Even repeated blood sugar readings don’t guarantee perfect control and a sudden spike in blood sugar level is expected every so often. High blood sugar levels lead to dry mouth or xerostomia.


Also, if you are suffering from diabetes and you have a persistent feeling of dry mouth that indicates that your blood sugar levels may be running high for a longer period. These high blood sugar levels not only give you a dry mouth but also make you more prone to gum and teeth diseases like tooth decay, gingivitis (gum infection), oral thrush (fungal infection), etc.

People with diabetes are advised to repeatedly check their blood sugar levels and keep a record. To fight dehydration from high blood sugar drink water every hour. If you have high blood sugar levels, visit your doctor. You may be given different drugs and a diabetic diet chart.


Apart from treating diabetes, your doctor may advise you to get some routine tests like Ultrasonography or sialometry (measures the rate at which saliva flows). sometimes just the alteration in dose or schedule of medicines you are taking might help to relieve xerostomia.


Sometimes bigger investigations might be required to make a proper diagnosis. Your doctor may ask you to undergo sialography through which any stone or mass can be detected. Also, patients suffering from dry mouth for a longer period should frequently visit dentists to rule out any tooth decay.
