Why do you always dry-heave when you brush your teeth and want to throw up?

Symptoms of dryness and nausea when brushing teeth may be caused by improper brushing, pharyngitis or pregnancy.
1. Improper brushing: If the toothbrush enters too close to the throat or the brushing amplitude is too large, which causes the toothbrush to touch the pharyngeal reflex area, it may lead to dry heaving and nausea and other symptoms.
2. Pharyngitis: Pharyngitis is an inflammation that occurs in the mucous membrane of the pharynx and the surrounding tissues, and patients may experience throat discomfort, sore throat, bad breath and other symptoms.
3. Pregnancy: When a woman is pregnant, the increased secretion of chorionic gonadotropin in the body can lead to pregnancy reaction, at which time the patient may experience regurgitation, vomiting, nausea and other symptoms.
Dry heaving when brushing teeth may also be caused by other reasons, and it is recommended that patients go to the gastroenterology department of regular hospitals and other related departments for further consultation.
