Helicobacter pylori is a bacterium that lives in the stomach, and many people believe that H. pylori is closely related to digestive disorders, such as peptic ulcers and stomach cancer. However, research has now found that H. pylori is also closely related to other diseases outside the digestive system, such as eczema, acne, and hair loss. Therefore, when there are some skin diseases such as acne, eczema, etc., accompanied by bad breath, indigestion, epigastric pain, nausea and other digestive symptoms, it is recommended that the patient should be able to perform a carbon 13 or carbon 14 breath test on an empty stomach. If you do have H. pylori infection, you should be sure to undergo the standard four two-week eradication regimen. We will find that after H. pylori is eradicated, acne is likely to be cured with it, so there is still a relationship between H. pylori and years of acne.
