[22F] Experiencing nausea and diarrhea postprandially

What might be happening

Based on the information you've provided, possible causes for your symptoms include:

• Gastroenteritis: This is an inflammation of the stomach and intestines, usually caused by a viral or bacterial infection. It can cause nausea, vomiting, and diarrhea.

• Food poisoning: This occurs when you eat food that is contaminated with bacteria, viruses, or parasites. Symptoms can start within hours of eating the contaminated food and can include nausea, vomiting, and diarrhea.

• Side effects of medication: Both fluoxetine and olanzapine can cause gastrointestinal side effects, including nausea and diarrhea.

• Anxiety: Anxiety can also cause physical symptoms, including nausea and diarrhea.

What you can do

1. Stay hydrated: Diarrhea can cause you to lose fluids quickly, so it's important to drink plenty of water. You can also drink oral rehydration solutions, which are available over the counter at most pharmacies.

2. Rest: Your body needs energy to fight off the virus or bacteria causing your symptoms. Getting enough sleep can help your body recover.

3. Eat small, light meals: If you can eat, try small amounts of bland foods like rice, bananas, or toast.

4. Continue taking your medications: Unless advised otherwise by a healthcare professional, continue taking your prescribed medications.

What you should look out for

If your symptoms persist for more than a few days, or if you experience any of the following, seek medical attention immediately:

• Severe abdominal or rectal pain
• Blood in your stool or vomit
• Signs of dehydration, such as excessive thirst, dry mouth, little to no urination, severe weakness, dizziness, or lightheadedness
• A high fever (over 101.5°F)
