Hi, My Dad is at age of 54 and have Diabetic for more than 15 years(Tablets only for 10years and Insulin also for last five years). He says his tongue became tasteless  for last one week. Is Diabetic causing this and how can be cured. Please let me know.
Thanks for your query, I have gone through your query. The tastelessness could be because of the loss of taste buds secondary to certain medicines like antihypertensives and antidiabetics. Loss of taste buds can also occur in gastroesophageal reflux diseases, in zinc deficiency, tobacco consumption (smoking), vitamin or nutritional deficiencies or anemia. Consult a general physician to rule out all these causes and treat accordingly. You can take becomes to correct any b complex deficiencies. Consume more of green leafy vegetables. Should have plenty amount of fluids(minimum of 3 liters). Maintain good oral hygiene.
