Radiotherapy is the treatment of radiation, and the main ways for patients to restore their sense of taste after radiation therapy are food stimulation of taste buds or medication. Patients lose their sense of taste after radiation therapy because the main location of radiation therapy is in the nasopharynx or cervical lymph node drainage area, and the taste buds are more sensitive to radiation, so patients will lose their sense of taste after radiation therapy. It is recommended that patients consume stimulating foods in moderation after radiation therapy, such as plums, onions, umeboshi, etc., which can stimulate the taste buds and be conducive to the recovery of the sense of taste. In addition, patients can also restore the sense of taste through medication. Patients can follow the doctor’s instructions to take oral rehabilitation of new liquid, methylcobalamin tablets and other drugs to promote mucosal and nerve recovery, which is conducive to helping patients restore the sense of taste. Patients who have no sense of taste after radiation therapy can help stimulate their taste buds through food and medication to restore their sense of taste, and it is recommended that patients eat nutritious food, such as chicken, lean meat, beef, etc. after radiation therapy. Patients should follow the doctor’s instructions to review on time, which is conducive to the recovery of the organism.
