What's with the belching and vomiting at the bottom of the throat?

Burping at the lower part of the throat may be related to improper diet, indigestion and reflux esophagitis.

1. Improper diet

If you eat more food that is easy to produce gas, it can lead to increased pressure in the stomach, causing gas overflow, resulting in hiccups, nausea and throat blockage.

2. Indigestion

When indigestion occurs, it can lead to slower food emptying in the stomach. When it is over-fermented to produce more gas, it is also easy to cause related symptoms.

3. Reflux esophagitis

For reflux esophagitis, acid and gastric contents reflux can stimulate the esophagus, throat mucosa, can lead to nausea, throat obstruction and other discomfort, and can also stimulate the diaphragm, resulting in hiccups.
