If you are experiencing stomach pain for an extended period after eating a banana, it might be a good idea to consult a doctor or healthcare professional. While it is uncommon for a banana to cause prolonged stomach discomfort, there could be other underlying issues that need to be addressed.
The doctor will be able to assess your symptoms, take your medical history, and conduct any necessary tests to determine the cause of your stomach ache. It's important to communicate any other symptoms you may be experiencing, as well as any changes in your diet or lifestyle that could be relevant.
In the meantime, you could try keeping a food diary to see if there are any patterns between the foods you eat and your stomach pain. Avoiding bananas and observing if the symptoms improve might also provide some insight.
Remember, seeking professional medical advice is the best way to ensure proper diagnosis and appropriate treatment.
