[27F] With black stool and abdominal pain post suspected food poisoning

What might be happening

Based on the information you have provided, here are some possible explanations for your symptoms:

• Gastrointestinal Bleeding: Black, tarry stools (known as melena) can be a sign of bleeding in the upper gastrointestinal tract, such as the stomach or small intestine. This can be caused by ulcers, gastritis, or other conditions. The metallic smell and your symptoms of weakness, dizziness, and weight loss are also concerning for this possibility.

  • Typical Treatments and Testing: This condition often requires urgent medical evaluation. Tests might include a stool test, blood tests, and possibly an endoscopy to look inside your digestive tract.

• Pepto-Bismol Side Effects: Pepto-Bismol can cause black stools as a harmless side effect. However, given your other symptoms, this might not be the only cause.

  • Typical Treatments and Testing: If Pepto-Bismol is the cause, the black stools should resolve after stopping the medication. However, given your other symptoms, it's important to rule out more serious conditions.

• Constipation: Your feeling of incomplete bowel movements and slight constipation could be contributing to your discomfort and abdominal pain.

  • Typical Treatments and Testing: Increasing fiber intake, staying hydrated, and possibly using over-the-counter laxatives can help relieve constipation. However, given your other symptoms, it's important to seek medical advice.

What you can do

While waiting to see a healthcare provider, you can try the following to help manage your symptoms:

1. Stay Hydrated: Drink plenty of water to help with constipation and overall well-being.
2. Monitor Your Diet: Avoid foods that might irritate your stomach, such as spicy or fatty foods. Eating a bland diet might help.
3. Avoid Pepto-Bismol: Since it can cause black stools, avoid taking it until you have been evaluated by a healthcare provider.
4. Rest: Ensure you get plenty of rest to help your body recover.
5. Use MDandMe: Journal your symptoms, track your progress, and share your notes with your healthcare provider. This can help them understand your condition better.

What you should look out for

Seek medical attention urgently if you experience any of the following:

• Severe Abdominal Pain: If your pain worsens or becomes severe.
• Blood in Vomit: If you notice blood in your vomit or vomit that looks like coffee grounds.
• Persistent Black Stools: If your black stools continue or worsen.
• Fever or Chills: If you develop a high fever or chills.
• Dizziness or Fainting: If you feel very dizzy or faint.
