[18F] Experiencing nausea, diarrhea, fatigue, and brain fog

What might be happening

Based on the symptoms you've reported, here are a few possible causes:

• Gastroenteritis: Often referred to as the stomach flu, this condition can cause nausea, vomiting, diarrhea, and fatigue. It's typically caused by a viral or bacterial infection.

  • Treatment usually involves rest, hydration, and eating bland foods until your symptoms improve.

• Food poisoning: This occurs when you eat contaminated food. Symptoms can start within hours of eating the offending food and can include nausea, vomiting, diarrhea, and fatigue.

  • Treatment is similar to gastroenteritis with rest, hydration, and bland foods.

• Irritable Bowel Syndrome (IBS): This is a chronic condition that affects the large intestine. Symptoms include cramping, abdominal pain, bloating, gas, diarrhea or constipation, and mucus in the stool.

  • Treatment often involves long-term changes to diet and stress management.

Please note that this is not an exhaustive list and other conditions could also be responsible for your symptoms.

What you can do

1. Rest and stay hydrated. Drink plenty of fluids, especially water and electrolyte-rich drinks like sports drinks or rehydration solutions.
2. Eat bland foods like rice, bananas, and toast until your symptoms improve.
3. Avoid foods that can irritate your digestive system, like spicy or fatty foods.
4. Over-the-counter medications like Pepto-Bismol or Imodium can help with diarrhea and nausea, but they should not be used for more than two days without consulting a doctor.

What you should look out for

You should seek immediate medical attention if you experience any of the following:

• Severe abdominal or rectal pain
• Blood in your stool or black, tarry stools
• High fever (above 101.5°F)
• Symptoms of dehydration, like excessive thirst, dry mouth, little to no urination, severe weakness, dizziness, or lightheadedness
• Diarrhea for more than three days
