What Could Be the Reason for a Sweet Taste in the Mouth?

In our daily lives, we often pay attention to maintaining oral hygiene. However, sometimes we may suddenly experience a sweet taste in our mouths, even when drinking plain water. When such situations arise, it is crucial to take them seriously as they may indicate various health issues. One common cause is damp-heat in the spleen and stomach, which can lead to a persistent sweet taste in the mouth. Additionally, diabetes and other gastrointestinal diseases can also manifest with this symptom.

1.1 According to traditional Chinese medicine, the sweet taste in the mouth is primarily caused by damp-heat in the spleen and stomach. The spleen and stomach, which belong to the Earth element in the Five Elements theory, reflect an excessive sensation when they are obstructed by damp-heat, resulting in a sweet taste in the mouth. This condition differs from spleen and stomach heat, which is more dry and fiery. Damp-heat involves both heat and dampness, creating a unique combination.

1.2 Certain diseases can also cause a sweet taste in the mouth. For instance, diabetes and other gastrointestinal diseases can disrupt the balance of enzymes in saliva during the early stages of the illness, leading to a sweet taste in the mouth and even in plain water. Additionally, disorders of the digestive system can increase the level of amylase in saliva, converting it into glucose and stimulating taste buds on the tongue, causing a sweet taste.

1.3 Generally, sudden sweetness in the mouth may indicate discomfort in the stomach or spleen. In such cases, adjusting the diet and eating sensibly can often help alleviate the symptom.

2.1 A sour taste in the mouth is believed to be a sign of spleen deficiency and excessive liver fire according to traditional Chinese medicine. It can also be associated with diseases such as gastritis and peptic ulcers, which may increase the levels of lactic acid and phosphoric acid enzymes in saliva, leading to a sour taste. To manage this, it is recommended to consume foods rich in zinc, such as small fish, sesame, almonds, black rice, egg yolks, and animal livers. Additionally, eating fruits and vegetables to supplement vitamins A, E, and B is beneficial. It is advisable to avoid stimulating and extremely hot or cold foods, as well as overeating.

2.3 A bitter taste in the mouth is a common complaint with various potential causes. It can be triggered by lifestyle factors such as insufficient sleep, smoking, alcohol consumption, improper diet, changes in climate, oral and gastrointestinal inflammation, and hormonal imbalances in women (especially during menopause). However, it can also indicate more severe conditions like acute liver or gallbladder inflammation, diabetes, or even cancer. To manage this, it is recommended to reduce the intake of spicy, greasy, and fried foods and increase the consumption of cooling foods. Avoiding alcohol, maintaining a positive mood, and avoiding stress can also help.

2.4 A spicy or hot taste in the mouth may indicate insufficient kidney yin and excessive liver fire. People with this condition often have a higher than average tongue temperature and may suffer from hypertension, neurosis, menopausal syndrome, or long-term low-grade fever. To manage this, it is advisable to reduce the intake of spicy, drying, greasy, and seafood foods, as well as animal organs. Avoiding alcohol and maintaining a calm and relaxed state can also be beneficial.

2.5 A salty taste in the mouth is believed to be caused by kidney deficiency according to traditional Chinese medicine. This condition is often accompanied by symptoms such as weakness in the waist and knees, dizziness, and tinnitus. People with a salty taste in their mouths are more prone to developing chronic conditions like pharyngitis, chronic nephritis, neurosis, and oral ulcers. These conditions can increase the levels of chloride compounds like sodium, potassium, calcium, and magnesium in saliva, resulting in a salty taste. Managing this condition involves reducing the intake of cold, spicy, and greasy foods, increasing < the consumption of fruits and vegetables, avoiding smoking and alcohol, maintaining regular sleep patterns, and engaging in moderate physical activity.
