- Dry Mouth: When you fast and abstain from eating or drinking for several hours, the production of saliva decreases. Saliva keeps the mouth clean and moist. A reduction in saliva leads to an increase in bacteria, which can cause bad breath.
- Metabolic Changes: Extended periods without food intake can initiate the process of burning fat for energy, known as ketosis. During ketosis, the body produces ketones, which are expelled through breath, resulting in a distinct odor.
- Dietary Imbalance: Consuming unbalanced meals during suhoor (pre-dawn meal) and iftar (breaking the fast) can also contribute to bad breath, especially if meals are rich in spices or fats.
- Lack of Oral Hygiene: Skipping brushing or oral hygiene practices near the time of breaking the fast can result in the persistence of bad breath.
