H. pylori and chest tightness: what to know

H. pylori irritates the stomach and may cause upper-abdominal discomfort, nausea or indigestion. Acid reflux can create a burning or pressure sensation behind the breastbone, but chest tightness can also occur with angina, asthma, COPD, anxiety or panic. The location and trigger alone cannot safely identify the cause.

Notice whether symptoms start with exertion, breathing, meals or emotional stress, and whether breathlessness, sweating, dizziness or nausea occur. See [Chest Tightness](/symptoms/chest-tightness/) and [Acid Reflux](/conditions/acid-reflux/) for related information.

If tightness is new, recurrent or unexplained, arrange a clinical assessment rather than assuming it is H. pylori. Bring details about onset, duration, activity, meals, breathing and prescribed medicines. If H. pylori has been confirmed, follow the treatment plan, but do not use that diagnosis to dismiss chest symptoms.

People with a diagnosed airway condition should use inhalers only as directed; [Inhaler Therapy](/treatments/medical-management/inhaler-therapy/) may be discussed with a clinician.

Call emergency services now for severe or persistent chest tightness, pressure spreading to the arm, jaw or back, breathlessness, fainting, cold sweating, blue lips or sudden weakness. Do not drive yourself if you feel seriously unwell.

Could this be heart-related, reflux-related or caused by the lungs? What tests are appropriate? What symptoms mean I should seek emergency help? Should my H. pylori treatment change?
