I have been throwing up most mornings when brushing my teeth, Just bile.  But i sometimes carry on heaving for a while. But if i think about it during the day i heave, If i cough i heave and when i brush my teeth at night i am sick, As i have eaten. I seem to pick up colds and upset tummies a lot lately.
Hi. Welcome to Chat Doctor. I read your query. Do you clean your palate and tongue while brushing? Maybe you tend to clean it too far deep or maybe you have oversensitive palate or gagging sensation. This can also be due to gastric troubles and acidity. Try brushing with a soft brush using correct brushing method (ask your dentist). Use mouthwash. Clean your tongue, palate and oral mucosa gently with a gaze piece. Take deep breaths through nose while brushing or cleaning mouth and think of something else than focusing on vomiting sensation. If the problem persists, consult a physician for upset stomach and gastrointestinal check up. Hope the answer helps you. Thank you!
