Can Diabetes Cause a Metallic Taste in your Mouth?

Can Diabetes Cause metallic Taste In Mouth

If you have diabetes, it is important to keep your blood sugar within a healthy range. In the event that your blood glucose levels become too high, you may notice a funny, irritating metallic taste in your mouth. This metallic taste is medically known as dysgeusiaDiabetes and metallic taste can be related to other causes as well, such as certain medications. 

What is Diabetes?

Chronic high blood sugar levels are indicative of diabetes. The food you consume breaks down into sugar (glucose) and is released into your bloodstream. As your blood sugar increases, the pancreas will release insulin. Insulin’s role in the body is to convert this sugar into energy. 

Unfortunately, diabetes prevents the body from making enough insulin or does not utilize the insulin properlyThis insufficient amount or improper use of insulin leads to an excess accumulation of sugar in the bloodstream, causing diabetes.

Does Diabetes Cause Metallic Taste in the Mouth?

Metallic taste in the mouth can be related to diabetes. The most common causes include:

Metformin used to treat Type 2 diabetes


Metformin is a prescription drug used to treat Type 2 diabetes. Metformin works by lowering blood sugar levels to a safe range. Although metformin helps stabilize blood sugar levels, it can also leave the unpleasant side effect of metallic taste in the mouth.  


Diabetes causes high blood sugar in the body. Prolonged high blood sugar can cause damage to nerves in the body. Parageusia is a taste disorder that occurs when there is injury or damage to the central nervous system. When these nerves become damaged, taste disturbances, such as metallic taste, may develop.

Diabetic Tongue

Diabetic tongue is a combination of xerostomia, or dry mouth, and too much sugar in the saliva. Diabetic tongue can trigger a condition known asoral thrush. Oral thrush occurs when fungus starts to grow rapidly in the gums, tongue, and the roof of the mouth. Oral thrush often results in secondary burning mouth syndrome, which, in turn can cause metallic taste in the mouth.  

Oral Diseases

High blood sugar levels increase the sugar level in saliva. When your saliva contains high sugar levels, your oral health will become compromised. High sugar levels in saliva can increase your risk for cavities, gingivitis, and periodontitis. These can all cause metallic taste in the mouth.

Metallic Taste Problems

People suffering from metallic taste may experience a decrease in their quality of life. Metallic taste can often cause poor nutrition, as it causes aversion to certain foods because the food tastes unpleasant or different. This also often leads to people eating less or making poor nutritional choices. 

To mask the unpleasant taste caused by dysgeusia, people choose to eat spicier, saltier, or overly sweet foods. As a result of this, sodium and sugar intake often increase and can lead to complications or cause additional health problems. 

One study also showed that some dysgeusia patients begin drinking excess amounts of water. This can create a risk of polyuria, incontinence and higher risk of falls in the elderly. 

Will Metallic Taste from Diabetes Go Away?

Metallic taste resulting from diabetes may improve over time. If the metallic taste is due to medication, metallic taste should subside once your body adjusts to the medication. Adjusting your dosage may also help improve metallic taste.
