There are many different causes of GERD,  is is a digestive disorder that affects the lower esophageal sphincter (LES), the ring of muscle between the esophagus and stomach. Many people, including pregnant women, suffer from heartburn or acid indigestion caused by GERD and there are many questions regarding the root cause. However, there are many different ways to treat it and keep it under control regardless of the cause.

What is H Pylori?

H Pylori is one of the many types of bacteria that resides in the stomach and it has adapted with time just like everything else. The bacteria moves through the mucus lining of the stomach using the numerous flagella on the body. When they reach the wall of the stomach they will attach and start to release an enzyme known as urease, which takes urea and creates ammonia.

The ammonia level reduces the level of the acid in the stomach and then the bacteria multiplies and takes over the stomach. There are many different risks associated with those that have the bacteria in their stomachs, including gastric or stomach cancer and duodenal and stomach ulcers.

 Is GERD caused by H Pylori?

 It has been shown that H Pylori isn’t a common cause of acid reflux in many people, but there are always the rare few who are an exception to every rule. However, it might contribute to some of the atypical symptoms in many people. H pylori is an infection that needs to be treated and sometimes it can increase the level of acidity in some people, but it all depends.

There are numerous studies that have been done to show the correlation between the 2 and it was shown that those with GERD were more likely to have H Pylori than others. However, they didn’t find this to be the same of the patients with ISB or irritable bowel syndrome.

 This shows that having H Pylori is something that is not commonly found in patients that are suffering from GERD, especially those with Barrett’s esophagus or esophatigitis. However, those who have a lower severe symptoms of GERD are commonly found to have it.

Does low levels of stomach acid cause GERD?

There aren’t any studies that show that a low level of stomach acid causes GERD, but again it can cause some atypical symptoms of acid reflux in numerous people. However, it has been suggested that having not enough stomach acid might cause GERD, but there hasn’t been any conclusive studies regarding the correlation.


The top reason that there might be a lower level of stomach acid in most people is the use of drugs that reduce it, including proton pump inhibitors, H2 blockers and antacids. The 2nd common cause is a chronic inflammation of the stomach, which is called CAG or chronic atrophic gastritis and it is typical of those who have had an ongoing infection of H pylori along with PPI drugs.
There are many different ways to combat this disease, but there haven’t been any studies that link low levels of stomach acid or H pylori to a higher level of GERD and most often it is found to be the other way around.
