Week-Long Stomach Pain and Black Stool: When to Seek Help - Gastroenterology and Hepatology

Abdominal pain for one week + occasional black stools?


Hello, doctor.
Due to the end-of-term exams, my schedule has been a bit disrupted.
For the past week, I've been experiencing stomach pain at midnight (including pain under my right rib), specifically in the upper abdominal area.
It feels like my stomach is burning and churning, not the gurgling type.
I also feel nauseous, and my mouth has a slightly sour and bitter taste.
I tend to burp and pass gas easily after meals.
The first episode started when I had dinner an hour late, which marked the beginning of this week of stomach pain.
A few days ago, I skipped breakfast, and for the past two mornings, I've had intestinal pain and noticed black stools! Three months ago, I had a peptic ulcer (esophagus), which has since healed.
Currently, I'm taking antibiotics for a urinary tract infection.
Could this be related? What might be wrong with me, and should I see a doctor?

Hello Ms.
Lingling: It is still possible that your gastric or esophageal damage is caused by your lifestyle or antibiotics.
It is recommended that you return to the outpatient clinic for examination and treatment.

More Info


It sounds like you're experiencing a range of gastrointestinal symptoms that are concerning, especially given your history of peptic ulcer disease and the recent development of black stools. Based on your description, the burning sensation in your stomach, the urge to vomit, and the presence of black stools could indicate several potential issues that warrant medical attention.

Firstly, the burning sensation and discomfort in your upper abdomen, particularly under the right rib cage, could be related to gastritis or a recurrence of peptic ulcer disease. The fact that you have a bitter or sour taste in your mouth and experience excessive belching suggests that there may be an issue with acid production or reflux. This is often exacerbated by irregular eating patterns, stress, and certain dietary choices, such as consuming spicy or fatty foods, which can irritate the stomach lining.

The presence of black stools is particularly concerning. Black stools, or melena, can indicate bleeding in the upper gastrointestinal tract, such as from a bleeding ulcer or esophageal varices. Given your history of a peptic ulcer, this symptom should not be taken lightly. Even if the black color could be attributed to dietary factors (like iron-rich foods), the combination of your symptoms—especially the stomach pain and the black stools—suggests that you should seek medical evaluation promptly.

Regarding your current medication for urinary tract infection (UTI), antibiotics can sometimes lead to gastrointestinal side effects, including nausea and changes in bowel habits. However, they are unlikely to directly cause the symptoms you are experiencing unless there is an underlying condition that is being exacerbated by the medication.

Given your symptoms and medical history, I strongly recommend that you see a healthcare provider as soon as possible. They may suggest performing an endoscopy to visualize the upper gastrointestinal tract and assess for any ulcers or lesions. Additionally, they might conduct tests to check for Helicobacter pylori infection, which is a common cause of peptic ulcers.

In the meantime, consider the following recommendations to help manage your symptoms:
1. Dietary Modifications: Avoid spicy, fatty, or acidic foods that can irritate your stomach. Stick to bland foods like rice, bananas, and toast until you can see a doctor.

2. Hydration: Ensure you are drinking plenty of water, especially if you are experiencing any gastrointestinal distress.

3. Avoid NSAIDs: If you are taking any non-steroidal anti-inflammatory drugs (like ibuprofen), stop taking them as they can exacerbate stomach issues.

4. Stress Management: Since you mentioned that your symptoms began during a stressful period (final exams), consider incorporating stress-reducing techniques such as deep breathing, meditation, or light exercise.

5. Monitor Symptoms: Keep track of any changes in your symptoms, including the frequency and appearance of your stools, and any new symptoms that may arise.

In summary, your symptoms are concerning, especially the black stools and the history of peptic ulcer disease. It is crucial to seek medical attention promptly to rule out any serious conditions and to receive appropriate treatment. Your health is important, and addressing these symptoms early can prevent complications.
