  https://my.clevelandclinic.org/health/diseases/21463-h-pylori-infection

  H. pylori is a bacteria that can cause peptic ulcer disease and gastritis. Only 20% of those infected have symptoms. Symptoms include dull or burning stomach pain, unplanned weight loss and bloody vomit. H. pylori can also inflame and irritate the stomach lining (gastritis). Untreated, long-term H. pylori infection can lead to stomach cancer (rarely). […] Most children with H. pylori infection don’t have symptoms. Only about 20% do. […] Symptoms and signs, if present, are those that arise from gastritis or peptic ulcer and include: Dull or burning pain in your stomach (more often a few hours after eating and at night). Your pain may last minutes to hours and may come and go over several days to weeks. Unplanned weight loss. Bloating. Nausea and vomiting (bloody vomit). Indigestion (dyspepsia). Burping. Loss of appetite. Dark stools (from blood in your stool). […] If you have an H. pylori infection, you have an increased risk for stomach cancer later in life.

• #4 Helicobacter pylori – Wikipedia

  https://en.wikipedia.org/wiki/Helicobacter_pylori

  Infection of the stomach with H. pylori does not necessarily cause illness: over half of the global population is infected, but most individuals are asymptomatic. Persistent colonization with more virulent strains can induce a number of gastric and non-gastric disorders. Gastric disorders due to infection begin with gastritis, or inflammation of the stomach lining. When infection is persistent, the prolonged inflammation will become chronic gastritis. Initially, this will be non-atrophic gastritis, but the damage caused to the stomach lining can bring about the development of atrophic gastritis and ulcers within the stomach itself or the duodenum (the nearest part of the intestine). At this stage, the risk of developing gastric cancer is high. However, the development of a duodenal ulcer confers a comparatively lower risk of cancer. Helicobacter pylori are class 1 carcinogenic bacteria, and potential cancers include gastric MALT lymphoma and gastric cancer. Infection with H. pylori is responsible for an estimated 89% of all gastric cancers and is linked to the development of 5.5% of all cases cancers worldwide. H. pylori is the only bacterium known to cause cancer.

  H. pylori enters the body through the mouth, moves through the digestive system, and infects the stomach or the first part of the small intestine. The spiral-shaped bacterium uses its tail-like flagella to move around and burrow into the stomach lining, which causes inflammation. […] Depending on where the infection occurs in the stomach, H. pylori can also cause overproduction of stomach acid. […] While there is no formal progression of the H. pylori infection, several steps are well documented. This process is very slow, taking decades, and may stop at any step because gastric cancers probably require several other factors to develop in addition H. pylori infection. […] Stage 2: Inflammation of the stomach lining (chronic gastritis) […] Stage 3: Loss of stomach cells and impaired digestive system (atrophic gastritis) […] Stage 4: Transformation of the stomach lining (intestinal metaplasia) […] Stage 5: Beginning stages of stomach cancer (dysplasia) […] Stage 6: Stomach cancer (gastric adenocarcinoma)

• #15 Symptoms of Acute and Chronic H. pylori Infection | SpringerLink

  https://link.springer.com/chapter/10.1007/978-981-287-706-2_15

  Helicobacter pylori (H. pylori) has urease and ureI gene to overcome gastric acid to survive on the acidic human stomach mucous membrane. Once H. pylori enters the stomach, acute gastroenteritis symptoms, such as nausea, vomiting, epigastric pain, and heartburn, occur. These symptoms emerge within the first week of infection, and the symptoms reach their maximum severity on the ninth to 12th day of the infection. Then, the symptoms get better, and most of those are gone after 2 weeks of the infection. Based on a gastroscopic view of H. pylori infection, erythema can be seen on the gastric mucosa after the fifth day of infection, and gastric juice pH is reported to be 7.0, which is neutral. Then, the erythema findings get better after 2 weeks of infection, while the gastric juice pH is 7.5, which is indifferent. Later, the gastroscopic view is back to normal after 74 days of H. pylori infection, while lymphocyte and plasma cell infiltrations increase, and gastric juice pH becomes 2. Thus, continued H. pylori infection after 2 months can be considered as chronic infection. Once chronic infection is maintained, H. pylori influences on symptoms that might be related to the brain-gut axis through various immunologic mechanisms and is expected to cause symptoms on organs other than stomach. However, unequivocal data concerning the direct and immediate effect of H. pylori infection on the brain-gut axis are still lacking. Therefore, further studies evaluating the clinical importance of these host-bacteria interactions will improve our understanding of H. pylori infection pathophysiology.

  Atrophic gastritis and intestinal metaplasia are precursors to gastric cancer and are strongly associated with H. pylori infection in adults. Gastric cancer types include adenocarcinomas, which account for 95% of gastric cancers, and gastric lymphomas, such as mucosal-associated lymphoid tissue (MALT) lymphoma. Gastric adenocarcinoma can be classified according to anatomic site of occurrence. Cardia adenocarcinomas are located near oesophagus, whereas non-cardia adenocarcinomas occur in the mid and distal region of the stomach. Nearly 90% of non-cardia adenocarcinomas and 72-98% of gastric MALT lymphomas are associated with H. pylori.

  H.Pylori can also be the cause of different types of stomach or gastric ulcers. An ulcer is a break in the lining of the stomach or upper bowel (the duodenum). Ulcers occurring in these areas are often called peptic ulcers. H.Pylori is the cause of about 90% of ulcers in the duodenum. The common symptom is pain in the upper part of the abdomen. However, it is important to recognise that pain is often not due to ulcers as some ulcers cause no symptoms. A small proportion of ulcers cause serious complications such as bleeding or perforation (bursting). […] H.Pylori is also the cause of about 70% of stomach ulcers. Most of the remaining 30% are due to drugs taken for arthritis (non-steroidal anti-inflammatory drugs), or aspirin taken to prevent heart attacks or strokes. Some patients have both risk factors. The symptoms and complications of stomach ulcers are the same as for duodenal ulcers. Modern anti-ulcer drugs heal virtually all duodenal and stomach ulcers but there is a high chance that the ulcer will come back if H.Pylori is not eradicated. If H.Pylori infection is cured, the risk of the ulcer returning is very low, unless aspirin or anti-inflammatory drugs need to be taken.
