Stomach pain can be triggered by a variety of factors. The most common causes include an unbalanced diet, excessive consumption of coffee or alcohol, stress, taking certain medications, an infection with Helicobacter pylori and digestive problems caused by insufficient chewing. Hyperacidity or hypoacidity of the stomach can also cause symptoms. However, the actual cause often lies in the intestines – for example, due to impaired intestinal flora or poor pre-digestion in the mouth. In order to alleviate stomach pain in the long term, it is important to identify the exact cause and treat it holistically.
