No no, he makes a good point.

He drank one whole bacterium?
User avatar #1 - dabronydude (03/26/2014) [+] (13 replies)
but that only proves half of it,
yes he proved bacteria is a cause but did he also try to see if stress might also cause it?
proving one thing and from that claiming something is now impossible is not how things work.

We have numerous studies where we've biopsied stomach and duodenal mucous tissue and found the H. pylori bacterium inside the glands, the mode of infection is by ingestion.
Also, treatment with antibiotics reduces acid levels and ulcers in most cases, confirming the theory.
Second most common cause is use of NSAIDs, like Aspirin.

The guy below has a point. Stress (the psychological one) doesn't cause the ulcers per se. It may predispose you to the condition by increasing your craving of fatty and acid-inducing foods, it increases blood pressure, and it affects your immune system probably promoting inflammation.

He was just stressed about drinking the bacterium.

That must have been pretty stressful waiting for the ulcers to form.
User avatar #25 - Zydratejunkie (03/27/2014) [-]
Or maybe he was so stressed out about the prospect of developing stomach ulcers from drinking the bacterium that he developed stomach ulcers.

'drank bacterium'
'Bacterium' is singular, mate. Also, the man didn't give himself an ulcer, let alone plural 'ulcers'; he developed gastritis, an inflammation of the stomach lining which is usually a precursor to an ulcer. Obviously, this didn't explicitly prove a connection between the bacteria H. pylori and ulcers, but it steered subsequent scientific inquiry and medical treatment in that direction.

All that proves is that bacteria cause stomach ulcers. It doesn't disprove that stress cause ulcers. But I'm guessing there must've been more to this experiment or else he wouldn't have won the Nobel Prize. Unless they just felt sorry for him.

From what I can find it was a belief that stomach acids were causes exclusively by things like stress, spicy food, and too much acid, and this view had been held for decades. Doctors and scientist thought that stomach ulcers couldn't be caused by bacteria, since the bacteria would all be killed by the acidic environment of the stomach. This man and his partner proved those people wrong.

this is worded terribly. the fact that ingested a lot of bacteria and developed an ulcer only indicates that bacteria can likely cause ulcers. it tells us nothing about whether or not stress can cause ulcers.

since I don't know anything about this man, and I'm not going to be bothered to look it up, I'm just assuming this was edited down to fit into an image macro, since I'm sure the Nobel committee knows what it's doing.

Stress can worsen symptoms, but it is not the cause.
While excessive stomach acid secretion certainly plays a role in the development of ulcers, a relatively recent theory holds that bacterial infection is the primary cause of peptic ulcers. Indeed, research conducted since the mid-1980s has persuasively demonstrated that the bacterium Helicobacter pylori (H. pylori) is present in more than 90% of duodenal ulcers and about 80% of stomach ulcers.

Other factors also seem to contribute to ulcer formation. Overuse of over-the-counter painkillers (such as aspirin, ibuprofen, and naproxen), heavy alcohol use, and smoking exacerbate and may promote the development of ulcers.

Tell it to my ulcer, that stress does not cause it.

I went to a doctor, they took a piece of my stomach with probing, tested it for that bacteria and it came back negative. Still every time i get stressed out i get pains, or when i eat food with A LOT of preservatives.

i'm no scientist, but is there any correlation between build up of bacteria in the stomach and stress?

Oh, he drank bacterium? As in a singular bacterium? That must have been difficult. No wonder he won a ******* prize

Fact sites with poor grammar can get ****** .

Is this the guy who discovered the h. pilori bacteria?
