    • Antidepressants: Some medications used to treat depression can affect taste perception.
  • Dry Mouth (Xerostomia):

    • Respiratory Infections: Sinusitis, respiratory infections, or postnasal drip can lead to an unpleasant taste.
  • Gastroesophageal Reflux Disease (GERD):
    • Stomach acid flowing back into the esophagus (acid reflux) can cause a sour or bitter taste in the mouth.
  • Dietary Factors:

  • Neurological Conditions:
    • Certain neurological conditions, such as multiple sclerosis or Bell’s palsy, can affect taste perception.

    • Chronic acid reflux can cause stomach acid to flow back into the mouth, leading to an unpleasant taste.
  • Pregnancy:
    • Hormonal changes during pregnancy can alter taste perception, leading to a metallic or unpleasant taste.
  • Tobacco Use:
    • Smoking or using other tobacco products can contribute to a bad taste in the mouth.
