Hi guys, great start to the article. Clean up your references per the email I forwarded to you recently. You don't need duplicate ref numbers if you're refering to the same reference. NeuroJoe (talk) 16:45, 30 October 2009 (UTC)

Great job on the article. You mention conditions (namely xerostomia, gastric reflux, lead poisoning, diabetes mellitus, and burning mouth syndrome) that dysgeusia can be a symptom of in your "Miscellaneous Causes" subsection, but I think if you could find some information on the mechanisms by which some of these conditions lead to dysgeusia your article would be even more useful. Some of this information may be hard to find (I just ran a few searches without success.) but if you did find anything it would be sure to make your article more medically significant and complete.

Also, as far as formatting your reflist goes, an improvement that will make your list of references more concise and save some space at the bottom of your article would be to use the following notation for sources that have been referenced previously:

<ref name="Name of previously cited article"/>

This should help you eliminate some of the repetitive references and make the article a bit neater. CharlesWCIItalk 20:36, 28 November 2009 (UTC)

In your article, emphasize the fact that the abnormal taste is usually metallicy or rancid in taste. I found this fact in many articles, and you never fleshed out this fact but only kept it as “abnormal.”

Under the “gustatory testing” section, you talk about magnitude matching. Explain further how using the 1000Hz sound reveals a comparison on the magnitude of taste. This was unclear to me as a reader, so further explain the procedure.

In diagnostic tools, the first paragraph, you talk about electrophysiological tests that can be done. You give an example using the trigeminal nerve-pontine brainstem-facial nerve pathway. Does this have to do with problems in dysgeusia? If so, explain how this nerve pathway correlates, and if not then maybe find an example that is relevant to the topic.

Reread your article for typos. One example is in the Miscellaneous Causes section: Dysgeusia was eliminated in 100% of these patients once when the obstruction was removed.

You talk a lot about the lack of saliva being a contributor to dysgeusia. You should explain its function and why it is necessary for taste. A good article is “Role of saliva in the maintenance of taste sensitivity” by R. Matsuo. IT can be found here on Pub Med:

In Psychological Impacts, you talk a lot about anorexia being a side effect, or weight loss. Is overcompensation of things such as salt and sugar ever an issue? And if so, does it ever lead to severe weight gain?

Overall, a very comprehensive article, and a job well done. Tothje (talk) 22:18, 29 November 2009 (UTC)


The fact that dysgeusia gives rise to a metallic flavor in the mouth was already stated in the causes section,but we added it also to the Symptoms section.

The footnotes have been adjusted.

The role of saliva has been further explained in the Causes section under chemotherapy.

More information about the mechanisms involved in conditions such as gastric reflux, lead poisoning, diabetes mellitus, and burning mouth syndrome could not be found. But since the role of saliva was expanded upon, it can be inferred that the loss of saliva in xerostomia would contribute to lack or alterations in taste.

Magnitude matching is basically comparing the relative strength of one sense to another in order to determine how they compare in strengths. Assuming the patient has normal hearing, he or she can rate intensities of a sound in relation to a taste stimulus. It's not really too complicated but just a test to see if an abnormal level of taste is present using some sort of standard scale (I could not find more information on this scale). It's important to keep in mind that its all relative to a normal sense, such as hearing the loudness of a tone and that this will be different for each person/case so each case should be treated individually.

The facial nerve is the seventh cranial nerve, which, in the current understanding of the gustatory pathway (refer to picture), plays a role in sensing taste. Hence, if lesions are present in this pathway, taste may be altered. I was just giving an example of a simple test that can be used to check if there is a problem in this pathway.

It is included in the Psychological Impacts section that patients must use caution when adding salt and sugar to foods. This is because diets high in salt and/or sugar are unhealthy.

Katie1341 (talk) 02:09, 7 December 2009 (UTC)

How could you group the caution over usage of salt and sugar in the psychological impacts section? That doesn't really make too much sense.

Dysgeusia and Tonsillectomy[edit]

I do not believe that nerve damage from surgery should be listed in the 'miscellaneous causes' of dysgeusia, given the fact that there is significant literature on dysgeusia from damage to the lingual branch of the glossopharyngeal nerve. I believe that this should be a separate section and I would really like some input on this before I go out of my way to put this. I also think there should be something put in the introductory paragraph about dysgeusia from nerve damage during surgery. Please give me some input before I change this - thanks!

Vitamin D[edit]

Should vitamin D be mentioned as a potential therapy? -- -- Vitamin D Deficiency Is a Cofactor of Chemotherapy-Induced Mucocutaneous Toxicity and Dysgeusia — Preceding unsigned comment added by (talk) 10:53, 25 September 2011 (UTC)

Pregnancy-related dysgeusia[edit]


I'm currently experiencing pregnancy-related dysgeusia, which I'm coming to understand is fairly common, and specifically results from the increased estrogen levels during pregnancy. I'd suggest adding this as a sub-section under causes. I'd do it myself, but alas, no time.

Thanks! (talk) 19:58, 28 October 2014 (UTC)
