Pregnant women with a burning sensation in their throat need to be alert to diseases such as reflux esophagitis and chronic gastritis. Many pregnant women experience changes in taste and hormonal disorders during pregnancy, resulting in excessive secretion of gastric acid. When gastric acid reflux occurs, it can cause damage to the mucous membrane of the esophagus and trigger an attack of reflux esophagitis, which not only causes a burning sensation in the throat, but also stimulates the diaphragm due to inflammation and can be accompanied by hiccups. During chronic gastritis, the inflammation of the gastric mucosa makes it more susceptible to the attack of stomach acid and causes a burning sensation in the throat. When the stomach swells and touches the diaphragm, the diaphragm is irritated and spasms occur, which can also cause hiccups.
