Dr. Josephson explains, "Sweet taste in the mouth can be caused by various medical problems. For instance, various metabolic problems can cause a sweet taste in your mouth; for example,
diabetes can cause this. Overall this symptom is poorly understood. We know that
diabetes can give a patient a sensation of sweet taste in the mouth."
What other medical conditions can cause this problem? "Neurologic problems such as a stroke, seizure disorder or
epilepsy can cause this problem. The patient may not even be aware that they are having a seizure,
epilepsy or a stroke because this may be the only symptom. Furthermore, virus that attack the olfactory (sense of smell) nerve or nerve that sends the signals of taste can lead to this sweet taste."
It doesn't stop there; Dr. Josephson continues: "On the other hand, infection in the sinuses, nose and/or throat, especially with the bacteria pseudomonas, can give you a sweet taste or smell." This type of bacteria can cause sinus and other ear nose and throat
infections especially in people with compromised immune systems including
diabetes aids and other immune system dysfunctions. This bacteria often causes urinary tract
infections and pneumonia. Though this bacterium can cause the sweet taste in your mouth,
infections by pseudomonas can be life-threatening.
But don't panic. Normal people can get infected with pseudomonas and do fine.
