Hello, the location of abdominal pain is significantly related to differential diagnosis.
The presence of dark-colored stools may indicate a positive fecal occult blood test, which requires further examination.
It is recommended to consult a gastroenterologist for precise abdominal pain localization and fecal occult blood testing, which will help in identifying the cause of the symptoms promptly.

Understanding gastrointestinal issues, particularly loose stools and abdominal pain, can be complex and multifaceted. Based on your description, it seems you have been experiencing loose stools since returning from Japan, accompanied by abdominal pain that is sometimes severe and associated with darker stool. These symptoms can arise from various causes, and it’s essential to consider both dietary and potential infectious factors.

Firstly, the change in your stool consistency to a loose or watery form could be attributed to several factors. One common cause is dietary changes, especially after traveling. Different food types, preparation methods, and even water quality can significantly affect your gastrointestinal system. For example, if you consumed foods that are rich in fats, spices, or unfamiliar ingredients, your digestive system might react by producing looser stools. Additionally, if you consumed any contaminated food or water, it could lead to gastroenteritis, which is an inflammation of the stomach and intestines, often resulting in diarrhea and abdominal pain.

The presence of abdominal pain, particularly if it is severe and persistent, raises the concern for other underlying conditions. The fact that you mentioned the pain is sometimes accompanied by darker stools is particularly noteworthy. Dark stools can indicate the presence of blood, which may suggest gastrointestinal bleeding. This could be due to several reasons, including peptic ulcers, gastritis, or even more serious conditions such as diverticulitis or colorectal issues.
Moreover, the pain you experience after eating could be related to food intolerances or allergies, which can manifest as abdominal discomfort and changes in bowel habits. Lactose intolerance, for instance, is common and can lead to symptoms like bloating, diarrhea, and abdominal pain after consuming dairy products. Similarly, gluten sensitivity or celiac disease could also be potential culprits if you have recently changed your diet.

Given the duration and nature of your symptoms, it is crucial to seek medical attention. A healthcare provider may recommend several diagnostic tests, including stool tests to check for infections, blood tests to assess for anemia or inflammation, and possibly imaging studies to evaluate your gastrointestinal tract. If necessary, an endoscopy may be performed to visually inspect the upper gastrointestinal tract for ulcers or other abnormalities.

In summary, your symptoms of loose stools and abdominal pain could stem from various causes, including dietary changes, infections, or more serious gastrointestinal conditions. It is essential to consult with a healthcare professional who can provide a thorough evaluation and appropriate management based on your specific situation. Early intervention can help prevent complications and improve your overall gastrointestinal health.
