Talk:Gastric acid

message: Contradictory statements: "Chemically it is an acid solution with a pH of 1 to 2 in the stomach lumen"
and "The pH of gastric acid is 2 to 3 in the human stomach lumen, the acidity being maintained..."  —Preceding unsigned comment added by 168.7.5.142 (talk) 20:30, 19 May 2009 (UTC)

message: Where does the body get chlorine atoms to make HCl from? From salt (NaCl)? If so, does this mean that while eating too much salt may be bad for your blood pressure, eating too little may make it impossible for you to digest your food? --Angr/comhrá 06:34, 25 Apr 2005 (UTC)
replies: text: Eating too high salt quantities will most certainly increase your blood pressure. Eating too little amounts of salt will reduce the amount of salt your kidneys excrete. When gastric acid is neutralized by NaOH from de pancreas NaCl is obviously formed, from which it can be absorbed again. I am not 100% sure whether or not NaCl is the only possible source of chlorine ions, but I am certain it is impossible not to receive it as it is in everything Redtails (talk) 22:20, 15 June 2009 (UTC)

message: The section named neutralisation uses sodium bicarbonate. Both in the text: "In the duodenum, gastric acid is neutralized by sodium bicarbonate.", and in the equation.  The rest of this article uses the bicarbonate ion, and the article about the duodenum also uses bicarbonate. I have not been able to find a reference to sodium bicarbonate anywhere else. Since HCl is already split into H+ and Cl-, the equation can be written without the chloride and the sodium ion. I get that introducing the H+ instead of HCl adds complexity (the reader must be familiar with acid solutions) and that the charge probably is maintained  closed to neutral by some positive ion. However, the introduction of sodium bicarbonate should have a reference.   — Preceding unsigned comment added by Haugstve (talk • contribs) 13:22, 14 October 2016 (UTC)

message: Gastric acid refers to the hydrochloric acid predent in gastric juice. gastric acid does not include enzymes etc. as far as i can work out from googling it. Bluemoose 10:03, 29 Apr 2005 (UTC)

message: The article mentions that many bacteria cannot survive exposure to gastric acid. What about other living contaminants, like fungi and viruses? --71.39.6.137 07:41, 26 March 2007 (UTC)
replies: text: Some species are capable of converting the urea present in the stomach to a base to protect themselves against the low pH levels. Most are not capable of surviving below a pH of 4 and ultimately die from protein denaturation. Redtails (talk) 22:23, 15 June 2009 (UTC)

message: I would support the merge between Gastric acid and Gastric juice. The two articles seem to cover almost identical subject matter. Scientific29 (talk) 05:45, 21 November 2010 (UTC)
thread_title:  Merge 

message: We were saying an acid was an acid in the first sentence. Then later that it was an acid.  Also not really covering the sections of the article.  Also poor communication to laypeople.
Probably a lot more needed in the whole article.  It is a mass of definition by blue-link.  I have a Ph.D. and have taken biochem (admittedly a long time ago) and found the article did not really describe the subject well.
Also only one source.

message: It is tricky to describe salts in any solution.  Gastric acid does not contain hydrochloric acid.  You can think of these solutions in such a way, but its probably technically incorrect. There are ions in these solution, but the idea that the cations "know" their anions is silly, although perhaps harmless.  To describe the composition of gastric acid, one should probably quote the solutes: a lot of ions (including pH).--Smokefoot (talk) 21:23, 28 January 2021 (UTC)
replies: text: While the cations don't know what anions are the anions do have an effect. For example bicarbonate ions and hydrogen+ will limiting out acidic a solution will be. Qtplatypus (talk) 06:19, 6 June 2023 (UTC)

replies: text: Gastric acid →  – Gastric acid is one component of gastric juice not an aka. Iztwoz (talk) 09:09, 5 May 2024 (UTC)

text: The components of stomach acid are primarily hydrochloric acid, various digestive enzymes and mucous sugars/proteins. It's my understanding that gastric acid refers to this mixture rather than just the hydrochloric acid, and that would make it an acceptable title. The pageviews for gastric juice also seem a little low (108 over 30 days) even compared to stomach acid (238 over 30 days) to be the primary topic name. Gastric acid has 100s of internal links while stomach acid and gastric juice each have fewer than 50, making me doubt gastric juice is really the most common name in-use as well. ― Synpath 14:29, 6 May 2024 (UTC)
replies: text: Hello Syn, have made some edits to the page and shall ask for move request to be removed. The use of gastric juice was added as an uncited aka some time ago. The page Gastric juice was merged to the page several years before the 'aka' was added. It had never been a question of renaming gastric acid but of simply citing it as a component but there is a lot more content on the acid.--Iztwoz (talk) 16:09, 6 May 2024 (UTC)
replies: text: Withdraw I should like to withdraw the move proposal.--Iztwoz (talk) 16:16, 6 May 2024 (UTC)

text: I did some searching and this chapter explicitly defines gastric juices as the stomach fluid mixture and uses gastric acid to refer to the acidic component(s). Perhaps that one can be added. I still think that the terms are probably used interchangeably in the broader population, but I suppose it doesn't matter much.  ― Synpath 18:40, 6 May 2024 (UTC)
replies: text: Thanks but relevant refs were already included in Secretion section. Gastric acid is probably more often referred to as it is involved in  conditions such as acid reflux or GERD.--Iztwoz (talk) 07:11, 8 May 2024 (UTC)
