Published: Last Updated on

We usually associate the sweet taste with pleasant things and delicious foods. Still, when you feel it continuously in your mouth, it becomes unpleasant; it prevents you from enjoying other flavors and reduces your appetite.

These taste disorders are medically called dysgeusia; alterations in the mouth’s typical taste are a must-have. Depending on what is ingested or specific circumstances, we can all feel how our taste changes, but dysgeusia is an alteration maintained over time and persists despite trying to end it.

If you feel sweet saliva, wondering what the cause it is the most normal thing in the world; that is why at FastlyHealwe bring you this article so that you know what diseases and conditions can manifest with this symptom, apart from explaining other symptoms that can help you identify the trouble. To find out, keep reading this article on sweet taste in the mouth: causes.

Sweet taste in the mouth, a symptom of diabetes

The sweet taste in the mouth is one of the symptoms that may indicate that the person has some diabetes. This disease is due to sugar in the blood caused by the body’s resistance to insulin. This fact causes glucose to enter cells and produce energy, which leads to it accumulating in the blood and creating hyperglycemia.

In addition to the sweet taste in the mouth, other symptoms can alert you that you have diabetes; here are some of them:

  • Constant thirst and desire to drink.
  • Increased appetite
  • Frequent urge to urinate.
  • Accused of weight loss.
  • Vision loss or blurred vision.
  • Drowsiness and tiredness
  • Gum, urine, or skin infections.
  • Healing is slower than usual.
  • Tingling sensation in the limbs or numbness.

A sweet taste in the mouth is a symptom of indigestion.

Another disease and medical condition that can cause this annoying symptom is gastroesophageal reflux disease. This disease causes indigestion that causes stomach acid to go the other way and travel up the esophagus. Anyway, it must be clarified that the sweet taste in the mouth is not one of its main symptoms mainly. GERD is diagnosed by :

  • Nausea and the urge to vomit after eating.
  • Feeling that food does not go down or stays in the stomach.
  • Heartburn that rises to the pharynx
  • Burning sensation and pain in the chest.

The sweet taste is in the second group of more specific symptoms depending on the person, such as:

  • Regurgitation of food and acid.
  • hypo
  • Cough and other respiratory symptoms.
  • Problems swallowing food.

Neurological disorders and sweet saliva

As you already know, from our nervous system, all the functions that have to do with the senses are controlled; be it smell, touch, taste, sight, or hearing. The nervous system is a complex structure that runs through our body, branching out from the spinal cord and brain to all areas of the body. But for it to function correctly, it is necessary that all the nerves accurately receive and send electrical signals to the brain, where they are processed.

When we chew food, for example, the taste nerves located under the tongue transmit taste signals to our brain. Our brain deciphers that it is one flavor or another, depending on the signal they send.

If our nervous system is affected by some underlying problem, such as a cardiovascular accident, these functions can be altered, and the wrong signals can be sent. One of the things that can happen is that electrical signals of the sweet taste are constantly being sent, causing this sensation always.

Sweet taste in the mouth: ketosis

When our body needs energy, it burns fat, breaking it down and generating a chemical known as ketone. This physiological procedure is called ketosis, and it creates a by-product from ketone called acetone. Once created, our body needs to eliminate it, and it does so through breathing. This causes the person to notice a strange taste in their mouth, a bite that many people define as sweet or fruity and others describe as metallic.

However, in people with metabolic problems, especially in diabetes mellitus, these bodies cannot be expelled; a metabolic state is known as ketoacidosis. This state is complex; it was the leading cause of death among people with diabetes before injectable insulin was invented.

This taste is different from bad breath caused by poor oral hygiene, as it has to do with the inability to burn carbohydrates to transform them into energy. Ketoacidosis is a common condition both in people with diabetes and in those who follow a diet with low carbohydrates, which causes normal blood glucose levels to drop.

If you have a sweet taste in your mouth due to your diet, you should review your eating habits, increasing the levels of carbohydrates you eat. In addition, we remind you that whenever you do a diet to lose weight, you must consult with a nutritionist or a doctor so that you can design a diet adapted to your needs, your health, and your condition.

Other diseases that cause a sweet taste

If you wonder why the sweet taste in the mouth is due, you should know that in addition to the diseases that we have already explained, some others conditions and conditions can manifest themselves through this symptom:

Pseudomonas infection

Although it is not especially common for this symptom to occur, it is possible, so we warn you about it. Pseudomonas is a type of bacteria that can cause some health problems. They usually attack the nose and ears, but if they attack the taste receptors, they can cause that particular sweet taste. Among the most common symptoms of pseudomonas infection, we find:

  • Nasal congestion
  • Chest pain
  • Trouble breathing
  • Taste effects

A blood test can detect these infections, which are treated with antibiotics.

Nerve infection

A viral infection that affects the nerve responsible for sending taste signals to the brain can cause the person to notice changes and disorders in taste, from feeling a metallic taste to catching sweet saliva.


Among the side effects of certain medications, we find alterations in taste or decreased saliva levels.

Sweet taste in the mouth after exercising

Have you ever noticed that carbohydrate-based drinks designed for athletes taste pretty bland? Now, have you noticed that when you drink them after exercising, they taste lovely? The reality is that the sweet taste in the mouth is entirely typical; in addition, it has also been shown that the perception of the sweet changes when we exercise.

When we exercise, we sweat; therefore, once finished, our body needs to ingest more carbohydrates to recover those we have lost and thus avoid dehydration. In this way, our whole body is oriented toward that objective. Also, the sense of taste-making makes us crave more those foods that provide us with the substances that we have lost. The sweet taste in the mouth after exercising is caused by the need to eat foods with salt. Producers of sports drinks know this, so they include less sugar, knowing that whoever drinks them will notice them sweeter.
