Hello, my 83 year old aunt who is a dibetic, has a metallic taste in her mouth. is has disrupted her life to the point she has stopped eating and now drinks only orange juice. my 79 year old mother my aunts youngest sister is very worried about her and asked for some sort of reason for this. My aunt heas not gone to the hospital yet but will go if it become much more serious. thank you. ..........I should have known there was some kind of hook hidden in your website. i understand that a doctor cant work for free but couldnt you be upfront enough tonote on the first line of you ad that there is a fee, albeit a small one but to receive your answer you will have to pay. some of us less paid individuals dont have the exrta $15 or $30 dollars to pay out when our family members are ill. our medical system here in canada is set up so that we can be treated for anything at a minimal cost or in other cases for free. i am sorry that i wasted both your time as well as mine to have a question answered that may be completely different from the actual problem. i feel i have been misled by your site. Please be considerate of lower income people who would feel somewhat better to be able to ask a medical question and be treated as a human not a dollar sign. Gordon Harper,  YYYY@YYYY

Thanks for using Chat Doctor. Read your query. Metallic taste in the mouth can be due to many etiological factors. Since your aunt is a diabetic, the medicines used for diabetic can itself induce the metallic taste in the mouth as an adverse effect. * Sometimes common cold, nasal infection or sinusitis are associated with this problem. *Poor oral hygiene, periodontitis often case the metallic taste in mouth. If I had a patient with the similar complaint I would have recommended them to have citrus fruits for next couple of days and maintenance of good oral hygiene. Also maintaining the sugar levels is very important. If the problem still persists, please consult your local doctor for further evaluation and treatment. Hope this was useful. Thanks and regards.
