Symptoms of a fungal throat infection, or esophageal thrush, include pain in the esophagus, nausea, vomiting, pain when swallowing and white lesions on the esophageal lining, states Healthline. An infection that spreads to the mouth as oral thrush may also exhibit lesions on the palate and cracking on mouth corners.
Esophageal thrush is a yeast infection of the throat caused by the candida albicans fungus, explains Healthline. This infection develops when the balance between the yeast and healthy bacteria in the body is upset and causes the yeast to proliferate. Patients with compromised immune systems, such as those suffering from cancer, the elderly, diabetes mellitus patients and babies born of mothers who developed the condition, are at a much higher risk of developing the condition than healthy people. In addition, those who smoke, have a chronic disease, take medications such as antibiotics, eat sugary foods and wear dentures also increase their risk of getting the infection.
Treatment for esophageal thrush aims to kill the fungus and prevent it from spreading further, according to Healthline. Options include eating yogurt to restore the natural bacteria balance in the body for healthy adults and antifungal medication for both babies and adults with compromised systems. If left untreated, esophageal thrush may spread to other parts of the body and also cause the inability to swallow.
