Hi,
A bitter taste in the mouth can be caused by several factors, including:
- GERD (
gastroesophageal reflux disease): When stomach acid flows back into the
esophagus, it can cause a bitter taste in the mouth.
- Medications: Certain medications can cause a bitter taste in the mouth as a side effect.
- Dental issues:
Gum disease, cavities, and other dental problems can lead to a bitter taste in the mouth.
- Infections: Sinus infections, respiratory infections, and other infections can cause a bitter taste in the mouth.
- Dehydration: Not drinking enough water can cause a bitter taste in the mouth.
- Nutritional deficiencies: Deficiencies in certain nutrients, such as zinc and
vitamin B12, can cause a bitter taste in the mouth.
- Liver or
gallbladder issues: Liver or gallbladder issues can cause a buildup of bile in the mouth, leading to a bitter taste.
In your case, the bitter taste in your mouth, along with
nausea and poor exercise performance, may indicate a possible gastrointestinal issue, such as GERD or liver/gallbladder issues. It is recommended that you see a healthcare professional for further evaluation and diagnosis.
