Why does drinking mineral water taste bitter?

Generally, a bitter taste when drinking mineral water may be caused by excessive water intake, indigestion, acid reflux, oral ulcers, or cholecystitis. If discomfort occurs, it is recommended to seek medical attention promptly. Detailed explanations are as follows:

1. Excessive Water Intake

Drinking large amounts of mineral water in a short period may reduce the concentration of saliva in the mouth, thereby impairing its lubricating and cleansing functions. This can lead to dryness and bitterness in the mouth, resulting in a bitter sensation when drinking mineral water. Usually, no other significant discomfort is present. It is recommended to drink water in moderation and avoid excessive intake at one time.

2. Indigestion

Eating too quickly may cause indigestion. When food is not fully digested in the gastrointestinal tract, it may produce a bitter taste, leading to a bitter sensation when drinking mineral water. Symptoms such as belching and reduced appetite may also occur. It is recommended to adjust eating habits, avoid overeating, and consume more easily digestible foods.

3. Acid Reflux

Acid reflux refers to the backward flow of acidic stomach contents into the esophagus, and sometimes even up to the throat and mouth, which may result in a bitter taste and thus a bitter sensation when drinking mineral water. It is often accompanied by symptoms such as chest pain and difficulty swallowing. Treatment under a doctor's guidance with medications such as omeprazole enteric-coated capsules, lansoprazole enteric-coated tablets, or hydrotalcite chewable tablets is recommended.

4. Oral Ulcers

Poor oral hygiene over a long period may lead to oral ulcers, which can produce certain chemical substances. When these substances mix with saliva, they may create a bitter taste, causing a bitter sensation when drinking mineral water. Symptoms such as gum bleeding and oral pain may also be present. Treatment under medical guidance with medications such as oral ulcer powder, Bingbor Powder, or ibuprofen tablets is recommended.

5. Cholecystitis

Cholecystitis is commonly caused by gallstones or bacterial infections. Water may stimulate the gallbladder, potentially aggravating the inflammatory response, thus causing a bitter taste when drinking mineral water. It is typically accompanied by symptoms such as right upper abdominal pain and nausea. Treatment under medical advice with medications such as racemic anisodamine tablets, cefixime capsules, or ursodeoxycholic acid capsules is recommended.

In daily diet, it is advisable to avoid spicy and raw-cold foods to prevent bodily discomfort.
