What causes a sensation of metallic taste in the mouth?

Hello,

Welcome to icliniq.com.

There are several possible causes for a metallic taste in your mouth. Some of the most common include the following.

1. Some medications, such as certain antibiotics, antihistamines, and blood pressure medications, can cause a metallic taste in your mouth as a side effect.

2. Poor oral hygiene, gum disease, or tooth infections can cause a metallic taste in your mouth. In some cases, metallic dental restorations (e.g., fillings, crowns) can also contribute to a metallic taste.

3. Hormonal changes during pregnancy can sometimes cause a metallic taste in the mouth. This is usually a temporary condition and resolves after pregnancy.

4. Inflammation or infections in the nasal passages or sinuses can affect your sense of taste, leading to a metallic taste in your mouth.

5. Deficiencies in certain vitamins or minerals, such as vitamin B12, zinc, or iron, may cause a metallic taste in your mouth.

6. Gastroesophageal reflux disease (GERD) or acid reflux can cause stomach acid to flow back into the esophagus and mouth, leading to a metallic taste.

7. Not drinking enough water can cause a dry mouth, which can sometimes be accompanied by a metallic taste.

9. Ingesting or inhaling substances like lead, mercury, or other heavy metals can cause a metallic taste in your mouth.

According to your history, the most probable cause would be the medications you take as they may cause a hormonal disturbance, so, please take your physician's opinion and ask him to change it if possible.

Thank you.
