Burping and left side chest pain can be caused by heart problems like angina, but they may also come from issues with the esophagus or stomach, such as acid reflux.
When you notice burping along with pain on the left side of your chest, there are a few possible causes. One cause could be heart-related issues like angina, which happens when your heart muscle does not get enough blood. In some cases, patients with angina have reported burping as a symptom. On the other hand, the pain and burping might be due to a problem in your esophagus or stomach, such as acid reflux. Acid reflux occurs when stomach acid flows up into your esophagus, and this can cause discomfort and burping. Additionally, some studies have mentioned that extra symptoms such as chest tightness and breathing difficulties might also appear in association with reflux or asthma-like issues. Because both heart conditions and gastrointestinal problems can sometimes look alike, it is important to share all your symptoms with your doctor so they can decide if further testing or treatment is necessary. Understanding the different ways these symptoms can come together helps your healthcare team give you the right care.
