Unlike an aftertaste caused by eating foods containing sugar or artificial sweeteners, a persistent sweet taste in the mouth is typically caused by an underlying medical condition.
These conditions can be serious and will often require medical attention, so it is vital to receive a proper diagnosis.

Diabetes
Diabetes is a common cause of a sweet taste in the mouth. Diabetes affects how well the body can use insulin, which has a direct effect on the body’s ability to control blood sugar.
Uncontrolled diabetes can result in high levels of sugar in the blood. Diabetes can sometimes cause a sweet taste in the mouth and is often accompanied by other symptoms.
Additional symptoms include:
- reduced ability to taste the sweetness in foods
- blurred vision
- excessive thirst
- excessive urination
- extreme fatigue
Diabetic ketoacidosis
Diabetes may also cause a serious complication called diabetic ketoacidosis. This happens when the body cannot use sugar for fuel and begins using fat instead. This causes an acid called ketones to build up in the body.
Excess ketones in the body can cause a sweet, fruity smell and taste in the mouth. Diabetic ketoacidosis may cause other symptoms, including:
- extreme thirst
- confusion
- fatigue
- nausea and vomiting
- abdominal cramping
Low carb dieting

People who are on low carbohydrate diets may find that they develop a similar fruity, sweet taste in the mouth. Carbohydrates are a common source of fuel in the body and going without them makes the body burn fat instead.
This process is called ketosis and causes ketones to build up in the bloodstream, producing a sweet taste in the mouth.
Anyone embarking on a low-carb or ketogenic diet should get guidance from a nutritionist or healthcare professional. Getting advice might help prevent harmful levels of ketones building up in a person’s body.
Infections
Certain bacterial infections can trigger a sweet taste in the mouth. Infections that affect the airways can interfere with how the brain responds to the taste senses.
Even simple infections, such as a cold, flu, or sinus infection, may cause the saliva to have more glucose in it. Glucose is a type of sugar, so may cause a sweet taste in the mouth.
If this is the case, the sweet taste will usually clear up when the infection is treated.
Neurological conditions
Nerve damage can also cause a persistent sweet taste in the mouth. People who experience seizures or who have had a stroke may experience sensory dysfunction. This can affect their senses, including taste and smell.
The outcome of this damage is complex and may be different in each case. In some cases, people may experience a sweet taste in their mouth that does not go away or that comes and goes.
Gastroesophageal reflux disease

Some people with gastroesophageal reflux disease (GERD) also complain of having a sweet or metallic taste in their mouth.
This is due to digestive acids that back up into the food pipe (esophagus) and eventually the mouth. This taste may seem to originate at the back of the mouth. Managing GERD with dietary and lifestyle changes will reduce symptoms.
Pregnancy
Pregnancy is another possible cause of a sweet taste in the mouth. Pregnancy causes changes in a woman’s hormones levels and digestive system, both of which can affect taste and smell.
Pregnant women may experience unexplainable sweet or metallic tastes in the mouth. The underlying cause could still be another condition, such as GERD or gestational diabetes, so any woman experiencing persistent changes in taste should talk with a doctor.
Medications
Some medications may also be to blame for a sweet taste in the mouth. Chemotherapy drugs often alter a person’s sense of taste.
This is a minor side effect of drugs that are used for serious illnesses, but doctors will still want to check and be sure that it is the medications causing the symptom.
If the sweet taste is affecting a person’s diet or quality of life, doctors may be able to prescribe an alternative.
Lung cancer
Lung cancer is an uncommon cause of a sweet taste in the mouth, but it should not be overlooked. Rarely, tumors in the lung or respiratory tract can raise a person’s hormones levels and affect their sense of taste.
