Why does my mouth feel bitter? Is it caused by disease?

If your mouth tastes bitter, it most likely means that you have some disease, the most likely being a digestive system disease. Some people also suffer from oral diseases, but if the bitter taste in your mouth only lasts for a short period of time, it is not a big problem.

1. A bad smell in the mouth, which is often bitter, is a sign of illness. It is most likely a digestive system disease. For example, a bitter taste in the mouth may occur when the gastrointestinal digestion function is poor. This may also happen in patients with gallbladder disease. In addition, because there is inflammation in the liver and gallbladder, especially in patients with cholecystitis and cholelithiasis, due to poor gallbladder function and biliary system motility disorders, abnormal bile secretion can occur, resulting in a bitter taste in the mouth, and is often accompanied by headaches, dizziness, flushed face and eyes, impatience and irritability, dry stools, and a red tongue.

2. Some oral diseases, such as cavities in teeth and gingivitis, can also cause bad odor and bitterness in the mouth. In addition, some patients with chronic diseases, such as diabetes, often have a bitter taste in their mouth. It is worth noting that bitter taste in the mouth is also common due to mental stress. Some people may experience bitter taste in the mouth due to great pressure from work and study, and when they are often angry, irritable, anxious, fearful, uneasy, insomniac, or drink too little water.

3. If the bitter taste in your mouth only lasts for a short period of time , don’t worry too much, it may disappear naturally. However, if the bitter taste in the mouth persists for a long time, and is even accompanied by symptoms such as abdominal pain, bloating, fever, weight loss, and obvious fatigue, it is necessary to look for the cause from all aspects. In addition to visiting the dentistry department to check for local oral problems, it is best to visit the gastroenterology department and do some related examinations, such as abdominal B-ultrasound or endoscopic examination, to check for cholecystitis, cholelithiasis, gastrointestinal diseases and other systemic diseases.
