According to Dr. Vipin Dehane - Head of Dentistry & maxillofacial Surgery, Fortis Hospital, India, a sour taste in the mouth is a common symptom that many people experience, which can appear temporarily or continuously for a long time. Although sometimes it is just a normal reaction after eating, if this condition persists, it can be a sign of a health problem that needs attention.
Gastroesophageal reflux disease (GERD)
This is the leading cause of sour taste in the mouth. When stomach acid flows up into the esophagus and even into the mouth, it can cause a burning, uncomfortable feeling and leave a sour or bitter taste. This condition often occurs after eating a full meal, lying down right after eating, or eating foods high in acidity.
Poor oral hygiene
Not brushing your teeth regularly or not cleaning your tongue can lead to the growth of bacteria in the mouth. These bacteria can produce unpleasant-smelling and flavored compounds, including sour taste. gingivitis, tooth decay, or gum infections can also contribute to this phenomenon.
Eating habits
Eating too many acidic foods such as oranges, lemons, tomatoes, vinegar... or using carbonated drinks, coffee, alcohol can increase the acidity in the mouth and cause sourness. Eating late or eating on time also affects digestive activity, easily causing acid reflux.
Side effects of drugs
Some medications, especially antibiotics, blood pressure medications, or iron and zinc supplements, can cause taste changes, leading to a feeling of sourness, bitterness, or metal in the mouth.
Digestive disorders
Digestive problems such as bloating, indigestion, stomach ulcers or liver-bile dysfunction can also affect taste and cause a sour taste in the mouth.
Pregnancy
Pregnant women often experience hormonal changes, changing their taste and taste buds. Acid reflux is also more common during pregnancy, contributing to the sour taste in the mouth.
When should you see your doctor?
If the sour taste in the mouth persists for many days, the cause is unknown or accompanied by other symptoms such as abdominal pain, difficulty swallowing, weight loss, frequent heartburn... then you should go to the doctor for timely diagnosis and treatment.
How to fix it
Keep your teeth clean.
Limit acidic foods.
Eat on time, avoid eating late at night.
Avoid lying on your stomach immediately after eating.
Drink enough water to neutralize acid and keep the mouth cleaner.
See your doctor if the condition persists or becomes serious.
