My firend has a loss of taste buds and smooth area on her tongue

This answer was rated:

My firend has a loss of taste buds and smooth area on her tongue with a swollen uncomfortable tongue.
She has been put on Folates and extra vitamins for a B12 deficiency and learnt through tests she is aneamic. However the tongue still has a smooth patch, a slight taste of metal, and swollen.
What else could this be?
Thank you for help.
Dear customer
Welcome to and thank you for your question.
I'm so sorry to hear of your friend's discomfort due to metallic taste & loss of taste buds. I will do whatever I can to help answer your questions
Although vitamin B12 deficiency is one of the most common causes of metallic taste & loss of taste buds & also the tests have shown this.
As your friend is already taking Folates and extra vitamins for a B12 deficiency since couple of months there can be other issues also.
Metallic Taste in Mouth is scientifically known as ‘Dysgeusia'.This is not serious but is of concern.It can be due to other following causes:
-Dental caries (Foul Taste),Oral infections like gingivitis or periodontitis,Fluctuation in hormone especially estrogen levels,Gastritis (Foul Taste),Gastro-esophageal Reflux Disease(GERD) or zinc deficiency.
She needs a dental check up & testing of hormonal levels & serum zinc levels.Also her gastric issues(if any) needs to be considered.Certain brain disorders as the possibility will be considered afterwards.
Her anemia is also most likely because of vitamin B12 deficiency.
So for confirmation,I advice you to make an appointment with your doctor to have these specific tests done so as to know the exact underlying cause & then treatment will be done accordingly.
Till then she can take citrus juices, lemonade and foods marinated in vinegar.This will increase the saliva production & removing the metallic taste of mouth. Every time she brush her teeth,she should make sure to brush her tongue also.It will help in lessening the metallic taste.
So bot***** *****ne is that she needs to make an appointment with her dentist & the doctor for the tests described above.
Hope this helped.
My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back, I am happy to address follow-up questions.
Thank you *****
