Gastric ulcer, melena?

About two weeks ago, I visited a doctor due to stomach discomfort.
The doctor performed an ultrasound and diagnosed me with a gastric ulcer and bloating.
I was prescribed medications, including Omeprazole and Gastronorm, for a week.
After finishing the medication, I felt better.
However, with midterm exams approaching, I stayed up late studying and drank coffee yesterday.
The dinner two nights ago was instant noodles, which I thought were ordinary, but they turned out to be slightly spicy (I haven't eaten spicy food for a long time).
Then, yesterday morning, I experienced diarrhea with dark-colored stools.
This morning, my stool was also muddy and dark.
(My bowel movements were generally normal until I consumed the instant noodles and coffee.) Could this be a direct result of irritating my stomach, causing a recurrence of the gastric ulcer with bleeding, leading to the dark stools? Should I return to see a doctor? What methods can help reduce the chances of a recurrence of the gastric ulcer? I would appreciate your response, thank you.

More Info

Black stool, or melena, can indeed be a concerning symptom, especially in the context of a diagnosed peptic ulcer. It often indicates the presence of digested blood in the stool, which can result from bleeding in the upper gastrointestinal tract, including the stomach and duodenum. Given your recent history of a peptic ulcer, it is essential to take this symptom seriously.

In your case, the consumption of spicy food and coffee, particularly after a period of avoiding such irritants, may have exacerbated your gastrointestinal condition. Spicy foods and caffeine can stimulate gastric acid secretion and may irritate the gastric mucosa, potentially leading to ulcer aggravation or even bleeding. However, it is also important to note that black stool can result from other factors, such as the ingestion of iron supplements or certain foods (like black licorice or blueberries), which can darken stool color without indicating bleeding.

Since you have experienced a change in stool color to black and noted that it is mud-like, it is advisable to consult your healthcare provider promptly. This is particularly important if you notice any additional symptoms such as dizziness, weakness, or abdominal pain, which could indicate significant bleeding or other complications.

Regarding your question about the duration for stool color to return to normal, it can vary. If the black stool is due to bleeding, it may take time for the underlying issue to resolve and for your stool to return to its normal color. If the black stool is due to dietary changes, it may return to normal once the irritants are removed from your diet.

To reduce the risk of peptic ulcer recurrence, consider the following strategies:
1. Dietary Modifications: Avoid spicy foods, caffeine, alcohol, and NSAIDs (non-steroidal anti-inflammatory drugs) as they can irritate the stomach lining. Instead, focus on a bland diet that includes foods like bananas, rice, applesauce, and toast (the BRAT diet).

2. Medication Adherence: Continue taking any prescribed medications, such as proton pump inhibitors (PPIs) like Pantoprazole, which help reduce stomach acid and promote healing. If you experience side effects, discuss alternatives with your doctor rather than discontinuing the medication.

3. Stress Management: Stress can exacerbate ulcer symptoms. Engage in relaxation techniques such as yoga, meditation, or deep-breathing exercises.

4. Regular Follow-ups: Keep regular appointments with your healthcare provider to monitor your condition. They may recommend periodic endoscopies or other tests to assess the healing of your ulcer and check for any complications.

5. Avoid Smoking: If you smoke, consider quitting, as smoking can impede ulcer healing and increase the risk of recurrence.

In summary, while dietary factors may have contributed to your current symptoms, the presence of black stool in the context of a peptic ulcer warrants medical evaluation. It is crucial to address this symptom with your healthcare provider to rule out any serious complications and to receive tailored advice on managing your condition effectively.
