[36F] Experiencing nasal congestion, fatigue, and gastrointestinal upset

What might be happening

Based on the information you've provided, here are a few possible explanations for your symptoms:

• Common Cold: This is a viral infection of your nose and throat. It's usually harmless, although it might not feel that way. Common symptoms include a runny or stuffy nose, sneezing, mild headache, and general fatigue.

  • Treatment typically involves rest, hydration, and over-the-counter remedies for comfort.

• Influenza (Flu): This is a more severe viral infection that can cause fever, chills, muscle aches, cough, congestion, runny nose, headaches, and fatigue.

  • Treatment typically involves rest, hydration, and possibly antiviral medications if diagnosed early.

• Gastroenteritis: Also known as the stomach flu, this condition causes inflammation in your stomach and intestines, which can lead to symptoms like nausea, vomiting, diarrhea, and abdominal pain.

  • Treatment usually involves rest, hydration, and eating bland foods as tolerated.

• Side effects of Sertraline: Sertraline can cause side effects such as nausea, diarrhea, and upset stomach.

  • If you suspect your symptoms are related to your medication, it's important to discuss this with your doctor. Do not stop taking your medication without consulting your doctor.

What you can do

While you should seek care from a healthcare professional for a formal diagnosis and treatment, here are some things you can do in the meantime:

1. Rest and hydrate: Make sure you're getting plenty of sleep and drinking enough fluids. This can help your body recover.

2. Over-the-counter remedies: Over-the-counter cold and flu remedies can help alleviate some of your symptoms.

3. Monitor your symptoms: Keep track of your symptoms and how you're feeling. This information can be helpful when you see a healthcare professional.

4. Avoid spreading the illness: If you have a cold or the flu, it's important to avoid close contact with others to prevent them from getting sick.

What you should look out for

If your symptoms worsen or you develop new symptoms, you should seek medical attention. Specifically, look out for:

• Severe headache
• High fever (over 100.4°F)
• Severe abdominal pain
• Blood in your stool or vomit
• Symptoms that persist for more than a week
