An overall meta-analysis and three subgroup-analysis were carried out for the included studies. Meta-analysis results showed that H. pylori infection was generally associated with the occurrence of pancreatic cancer (OR =1.30; 95% CI: 1.02–1.64; P=0.03) (Figure 2).
What other problems can H. pylori cause?
Besides ulcers, H pylori bacteria can also cause a chronic inflammation in the stomach (gastritis) or the upper part of the small intestine (duodenitis). H pylori can also sometimes lead to stomach cancer or a rare type of stomach lymphoma.
What organs are affected by H. pylori?
H. pylori is a type of bacteria that infects your stomach. It attacks your stomach and the first part of your small intestine (duodenum). This can cause redness and swelling (inflammation). Many people with the bacteria won’t have any symptoms.
What are unusual causes of pancreatitis?
In rare cases, pancreatitis may be caused by viral infections such as mumps, coxsackie B, mycoplasma pneumonia, and campylobacter.
Can H. pylori cause pancreatic cancer Related Questions
How long does it take for H. pylori to cause cancer?
Results: The patients were followed for up to 14.1 years (a mean of 5.6 years). During the follow-up, gastric cancer developed in 28 of the 1674 patients as long as 13.7 years after the cure of H. pylori infection.
What is the most common cancer associated with H. pylori?
Infection with H. pylori is the primary identified cause of gastric cancer.
What are the worst symptoms of H. pylori?
An ache or burning pain in your stomach (abdomen) Stomach pain that may be worse when your stomach is empty. Nausea. Loss of appetite. Frequent burping. Bloating. Unintentional weight loss.
What is the long term damage from H. pylori?
pylori can cause long-lasting irritation, swelling and pain in the stomach (known as ‘severe chronic atrophic gastritis’ or SCAG) and stomach ulcers. This can lead to cancer.
What is the number one cause of H. pylori?
You can get H. pylori from food, water, or utensils. It’s more common in countries or communities that lack clean water or good sewage systems. You can also pick up the bacteria through contact with the saliva or other body fluids of infected people.
Can H. pylori cause damage to the pancreas?
H. pylori infection has also been linked to the acute and chronic pancreatitis pathogenesis and it could be related to the development of autoimmune pancreatitis, diabetes mellitus and metabolic syndrome.
What autoimmune disease is caused by H. pylori?
Helicobacter pylori and immune thrombocytopenic purpura Immune thrombocytopenic purpura (ITP) is an autoimmune disease resulting from antibodies against platelet glycoproteins. Several microbial agents causing chronic infections such as HIV, Hepatitis C virus and H. pylori have been shown to be associated with ITP.
Can you become septic from H. pylori?
The prominent bronchovascular markings in the chest radiograph in our case were thought to reflect “atypical pneumonia” by the emergency department physician. However, in retrospect, these almost certainly reflected early pulmonary edema as part of a sepsis syndrome induced by the H. pylori bacteremia.
What is the biggest cause of pancreatitis?

Why is it so difficult to get rid of H. pylori?
Unfortunately, H. pylori is extremely difficult to remove. Due to the unique characteristics of the bacteria, it is able to create reservoirs that are protected by the biology of the stomach itself. Even if the reservoirs are eliminated, it may allow new mutant strains of H.
What are the stages of H. pylori?
The first step is chronic gastritis, followed after a time by the second step, atrophic gastritis. The third step is intestinal metaplasia, which may evolve into dysplasia. The last step is gastric adenocarcinoma.
What happens if H. pylori is left untreated for years?
H. pylori can also inflame and irritate the stomach lining (gastritis). Untreated, long-term H. pylori infection can lead to stomach cancer (rarely).
What are the symptoms of H. pylori cancer?
Abdominal pain or discomfort. Loss of appetite. Heartburn, indigestion or ulcer-type symptoms. Nausea and vomiting. Bloating or swelling in the abdomen. Diarrhea or constipation. Feeling full after eating small amounts of food. Bloody or black stools.
