Sometimes a sour or bitter taste indicates an underlying fever, but if this taste is experienced daily, it could be a sign of a stomach problem. Every oral problem is connected to the stomach.

What is the reason for a bitter or sour mouth?
Mornings are refreshing because the body has been repairing itself overnight. However, if you wake up with a sour or bitter taste in your mouth, you should be alert. Let's find out why.
Do you feel a sour or bitter taste in your mouth?
Sometimes a sour or bitter taste indicates an underlying illness, but if this taste is experienced daily, it could be a sign of a stomach problem. Every oral problem is linked to the stomach. If the stomach is healthy, oral disorders are less likely.
Due to which stomach problem does this happen?
Modern medicine has linked a sour or bitter taste in the mouth to stomach disorders. Increased stomach acid is the primary cause of a sour or bitter taste in the mouth. Modern medicine calls it acid reflux, but Ayurveda considers it a disease of the Pitta Dosha. According to Ayurveda, when there is an increase in Pitta in the body, the acid in the body increases. This not only causes stomach-related disorders but also weakens the bones and joints.
These mistakes at night also have an impact
There are many reasons for a sour or bitter taste in the mouth, including eating late at night, consuming alcohol and tobacco, liver dysfunction, a weakened digestive fire, and increased stomach acid. Poor eating habits and prolonged fasting can also contribute to increased stomach acid.
These Ayurvedic methods work
Ayurveda offers a solution to this problem. In Ayurveda, Triphala powder is considered the most beneficial for stomach ailments. Take half a teaspoon of Triphala powder with lukewarm water at night. This will cleanse the stomach in the morning and calm the bile at its root. Changing the timing of dinner can help reduce stomach acid.
Sleeping pattern also needs to be changed
Avoid eating late at night and eat dinner around sunset. Don't lie down immediately after eating; take a walk around and sleep on your left side. Science suggests that sleeping on your left side prevents stomach acid from rising up the esophagus and maintains good blood flow to the heart.
These remedies also help
Copper water is an excellent remedy for calming stomach acid. It has a cooling effect, which helps calm stomach acid. To do this, store water in a copper vessel overnight and consume it in the morning. Copper water will help detoxify the body. Drinking fennel and sugar candy water before or after meals helps improve digestion and also relieves bad breath. Also, avoid excessive stress and anxiety. Stress increases stomach acid production three times more than normal.
