Dehydration
. Another common cause is dehydration. During sleep, the body can go several hours without fluids, which limits saliva production. Saliva plays a crucial role in neutralizing acids and flushing away food particles.
How to ensure proper hydration: Drink water regularly throughout the day, especially if you have an active lifestyle or are exposed to hot weather. It’s a good idea to drink a glass of water before going to bed, and immediately after waking up in the morning to quickly restore normal saliva levels.
Liver and Bile Problems
: Although less common, liver problems can manifest as a bitter taste in the mouth. The liver plays a crucial role in filtering toxins and producing bile, which aids in the digestion of fats. Liver disorders, such as hepatitis, fatty liver disease, or other liver diseases, can lead to a bitter taste.
Other symptoms worth noting include: fatigue.
