Is there a way to prevent ageusia?

Avoid Causes. Deficiency of vitamin b3 (niacin) and zinc can cause problems with the endocrine system, which may cause taste loss or alteration. Disorders of the endocrine system, such as cushing's syndrome, hypothyroidism and diabetes mellitus, can cause similar problems. Local damage and inflammation that interferes with the taste buds or local nervous system should be avoided.
