[18F] Experiencing gastrointestinal and flu-like symptoms

What might be happening

Based on the information you provided, the most likely causes of your symptoms could be:

• Viral Gastroenteritis (Stomach Flu): This is an inflammation of your stomach and intestines caused by a virus. Symptoms can include stomach cramps, nausea, and diarrhea. Dark stool could be due to the rapid transit of stool through the intestines, not giving bilirubin enough time to be broken down.

  • Treatment typically involves rest, fluids to prevent dehydration, and over-the-counter medications to help with symptoms like fever and aches.

• Food Poisoning: This is an illness caused by eating contaminated food. Symptoms are similar to those of the stomach flu, including stomach cramps, nausea, and diarrhea.

  • Treatment is similar to that of the stomach flu, with a focus on staying hydrated and resting.

Please note that dark stool can sometimes indicate bleeding in the upper gastrointestinal tract, such as from a stomach ulcer or gastritis. However, this is less likely given your age and the absence of other symptoms like vomiting blood or severe stomach pain.

What you can do

1. Stay hydrated: Drink plenty of fluids like water, broth, or oral rehydration solutions. Avoid caffeine and alcohol as they can worsen dehydration.
2. Rest: Your body needs energy to fight off the virus. Getting extra sleep can help.
3. Eat light: If you can eat without vomiting, eat small amounts of bland foods like rice, applesauce, or crackers.
4. Over-the-counter medication: You can take over-the-counter medication for symptom relief, such as acetaminophen for aches and fever.

What you should look out for

You should seek immediate medical attention if you:

• Notice your stool is black and tarry, or you see visible blood in your stool
• Have severe abdominal pain
• Have symptoms of dehydration, such as dry mouth, not urinating much, or feeling extremely thirsty, dizzy, or lightheaded
• Have a fever over 102°F (38.9°C)
• Your symptoms persist for more than a few days
