Loss of Taste: Tongue Disorders and Their Causes

The tongue cannot taste the flavors of food?

Dr.
Li: Hello, I would like to greet you first.
I have developed a peculiar condition where I cannot taste the flavor of food.
I initially thought it was due to the common cold, so I decided to wait it out.
However, after more than half a month, it has not improved, and I now believe the situation is serious.
I tried chewing salt to test my taste sensation, but to my surprise, I could not taste it at all; it was not salty! I have never smoked, drank alcohol, gambled, or engaged in any vices.
My only pursuit, given my modest income, is to enjoy some inexpensive local delicacies.
I do not seek luxury or anything else; I just want to contribute to society through my work.
How could the heavens be so unfair to an ordinary good person, not allowing him to enjoy his later years? The hospital has prescribed me a medication called "Yue Ni Ting" (a type of film-coated tablet), but it seems ineffective.
Therefore, I am reaching out to you for guidance.
Thank you.
Sincerely, Gong Yue.

Dr. Li Jiaxuan reply Otolaryngology

Good morning, Mr.
Gongyue.
Individuals who lack taste often also experience a decrease in their sense of smell.
Given your age, it could be due to simple neurodegeneration or endocrine deficiency.
However, if you are concerned about other possibilities, Dr.
Hsu from the Department of Otolaryngology at Taipei Veterans General Hospital is an authority in this area.
It may be advisable for you to visit the hospital.
Wishing you good health.

Dear 弓月,
Thank you for reaching out and sharing your concerns about your loss of taste. It sounds like you are experiencing a condition known as ageusia, which is the complete inability to taste. This can be a distressing experience, especially for someone who values food as you do.
Loss of taste can be caused by a variety of factors, and understanding these can help in identifying the underlying issue. In your case, you mentioned that this started after a flu-like illness, which is a common trigger for taste disorders. Viral infections, particularly those affecting the upper respiratory tract, can lead to inflammation and damage to the taste buds or the nerves responsible for taste sensation. This is often temporary, but in some cases, it can persist longer than expected.

Other potential causes of taste disorders include:
1. Neurological Conditions: Conditions that affect the nervous system, such as Bell's palsy or other cranial nerve disorders, can impact taste perception. Since you mentioned having facial nerve issues, this could be a contributing factor.

2. Medications: Certain medications can alter taste perception. If you are taking any new medications, it might be worth discussing with your healthcare provider to see if they could be affecting your taste.

3. Nutritional Deficiencies: Deficiencies in certain vitamins and minerals, particularly zinc and vitamin B12, can lead to taste disturbances. Ensuring you have a balanced diet or considering supplementation might help.

4. Oral Health Issues: Dental problems or infections in the mouth can also affect taste. It’s important to maintain good oral hygiene and consult a dentist if you suspect any issues.

5. Psychological Factors: Stress and depression can alter taste perception as well. Given your concerns about your overall well-being, it might be beneficial to explore this aspect with a mental health professional.

Since you have already tried medication without success, I recommend a few steps moving forward:
1. Consult an ENT Specialist: An Ear, Nose, and Throat specialist can perform a thorough examination to rule out any anatomical or functional issues affecting your taste.

2. Taste Testing: Sometimes, a structured taste test can help determine if there are specific tastes you can still perceive, which can guide further treatment.

3. Nutritional Assessment: A dietitian can help assess your nutritional intake and suggest any necessary changes or supplements to address potential deficiencies.

4. Follow-Up on Medications: If you are on any medications, discuss with your doctor whether they could be contributing to your taste loss and if alternatives are available.

5. Patience and Monitoring: Taste recovery can take time, especially after a viral infection. Keeping a journal of your symptoms and any changes can help you and your healthcare provider track your progress.

In conclusion, while the loss of taste can be alarming, it is often reversible, especially if the underlying cause is identified and treated. I encourage you to seek further evaluation and support from healthcare professionals who can provide a comprehensive approach to your symptoms.
Take care, and I hope you find relief soon.

Best regards,
