Other Causes of Ageusia
A deficiency of zinc and vitamin B3 may lead to endocrine system issues, which eventually causes alteration or loss of taste. In addition, ageusia is associated with some disorders of this system, such as diabetes mellitus, hypothyroidism, and Cushing’s syndrome. Some medications can trigger this condition as a side effect. These include antiproliferative medications and antirheumatic drugs. Other possible causes of ageusia include glossitis, radiation therapy, the use of dentures, or smoking. They basically cause inflammation or local damage that can interfere with the local nervous system or taste buds. Some rare triggers might be liver failure, kidney failure, anxiety disorder, and aging. [4]
