Talk:Vitamin deficiency

Stub-worthy, or better?
The essential question is whether any content can be generated for this article that is not covered in the individual articles on vitamin deficiencies (or the parallel vitamin articles). David notMD (talk) 01:19, 3 February 2019 (UTC)
 * Adding refs - intention is to add the NIH fact sheet and DRI chapter for each individual vitamin deficiency. These are all free references. Still does address question of whether there is content for the body of the article. David notMD (talk) 03:28, 3 February 2019 (UTC)
 * Copied History section from Vitamin article, then shortened a bit. David notMD (talk) 03:50, 3 February 2019 (UTC)
 * Copied content from Food fortification into a section on prevention. David notMD (talk) 12:09, 5 February 2019 (UTC)
 * A section that may have merit would be a presentation on how vitamin deficiency is defined. Easy if there is a consensus on what are valid measurements, for example plasma concentration, but difficult if there is no biomarker. And likewise, is a deficiency what causes a specific deficiency disease - vitamin D and rickets - or is there an optimal intake which is higher than what is needed to avoid a frank deficiency? Meanwhile, still adding the NIH and DRI refs for each vitamin. David notMD (talk) 11:55, 3 February 2019 (UTC)
 * David, thanks for your substantial effort to improve this article. In my opinion, it is certainly C class and approaching B classification. Referring to Quality scale, under "Reader's experience", the article now is "useful to a casual reader" (C class), "although the content may not be complete enough to satisfy a serious student or researcher" (B class). I will change the classification to C, subject to input or revision by others. As I feel we should follow the editing suggestions to attain B class (see Quality scale, Editing suggestions: "A few aspects of content and style need to be addressed. Expert knowledge may be needed. The inclusion of supporting materials should be considered if practical"), it would be helpful to have a few points on your to-do list here on the talk page. One note working backwards: all vitamin DRIs derive from knowledge of diseases caused by deficiencies, as presented in your section on Individual vitamin deficiencies. Perhaps this section needs expansion. Will be reviewing and working with you on this. --Zefr (talk) 17:16, 8 February 2019 (UTC)
 * I am working through the individual vitamin deficiency statements, to include whether they are rare or common. And if there is a diagnosis based on plasma or serum concentration. I had been thinking of a separate Treatment section, but have decided against it, as too close to giving medical advice. Welcoming your and any other editor's assistance. Planning to get this close to closure by the 9th so it would qualify for a Did You Know via 5X expansion completed within seven days. If I submit, will make clear that the History and Food fortification sections were copied in, not created de novo. David notMD (talk) 20:57, 8 February 2019 (UTC)

Thank you for reviewing and upgrading to C-class. I am still working on the individual vitamin statements. The section was getting long, so split to fat- and water-soluble. David notMD (talk) 05:18, 9 February 2019 (UTC)
 * This was a useful edit for division of topics. --Zefr (talk) 00:03, 11 February 2019 (UTC)

Added Defining deficiency section David notMD (talk) 14:22, 9 February 2019 (UTC)
 * I do not intend to add any more to the article (pending the DYK review). David notMD (talk) 23:27, 10 February 2019 (UTC)
 * Great work. I noticed some of the history sources are dead links. Will be reviewing and copyediting further in coming days. --Zefr (talk) 00:03, 11 February 2019 (UTC)
 * Section copied from Vitamin, so dead there too. Thanks for being involved. For the moment, I am vitamin fatigued David notMD (talk) 01:28, 11 February 2019 (UTC)

No images
Some of the articles on vitamin deficiencies have images of people that show the symptoms of deficiency (scurvy, rickets...), but in my opinion too morbid to include in this general article. David notMD (talk) 13:40, 10 February 2019 (UTC)


 * Pictures do have much power, good or bad. Until hurting effects. I do not look for (these) pics now, please. But if ´too morbid´, then it is not information, it is hurting.
 * I just want to support the saying of this note. Thanks this note.

Vitamin deficiency has effects to the stomach(gastric)-intestinal household
The biggest (most important) immune-section (-organ, -area) is the stomach-intestinal houshold, I am told these days, of the body immune-system. Sorry, I just cannot take the time of effort, to view, whether this is mentioned in the article. If: then very sorry. (Then, if wished, I can delete again this note here. --Visionhelp (talk) 17:07, 27 March 2021 (UTC)

Avitaminosis and hypovitaminosis
Here in the infobox they are listed as synonims. Literally, one means total absense of some vitamin (which is extremely unlikely to happen), and the other means relative deficit. Is there a source that explains the history of these terms? Interestingly, in many languages both articles exist. --Hwem (talk) 07:19, 10 February 2022 (UTC)
