[34F] Experiencing nausea, vomiting, and other gastrointestinal symptoms

What might be happening

Based on the symptoms you've described, the following conditions could be possible:

• Gastroenteritis: This is an inflammation of the stomach and intestines, usually resulting from a viral or bacterial infection. Symptoms can include nausea, vomiting, and diarrhea, although you've mentioned that you do not have diarrhea. It's also common to have a loss of appetite, which could explain your fatigue.

  • Treatment usually involves rest, hydration, and over-the-counter remedies. Antibiotics may be prescribed if a bacterial infection is suspected.

• Gastritis: This is an inflammation of the stomach lining, which can cause nausea, vomiting, and a feeling of fullness in your upper abdomen after eating. Gastritis can be caused by various factors, including long-term use of NSAIDs, infection with Helicobacter pylori bacteria, and certain autoimmune disorders.

  • Treatment usually involves taking antacids and other drugs to decrease stomach acid, which can help speed the healing process.

• Pregnancy: Some of your symptoms, such as nausea, vomiting, fatigue, and increased urination, can also be early signs of pregnancy. Given your age and sex, and the fact that you're sexually active and not using protection, it's possible that you could be pregnant.

  • A home pregnancy test can usually detect a pregnancy from the first day of your missed period. If you're pregnant, you should start prenatal care as soon as possible.

What you can do

While waiting for your appointment with a healthcare professional, here are some things you can do to manage your symptoms:

1. Stay hydrated: This is especially important if you're vomiting. Try to sip small amounts of water regularly.
2. Eat small, light meals: If you can, try eating small amounts of bland foods, like rice, applesauce, or crackers.
3. Rest: Your body needs energy to fight off an infection. Getting rest can help.
4. Avoid irritants: If you have gastritis, it can help to avoid things that aggravate your stomach lining, like alcohol, NSAIDs, and spicy or fatty foods.

What you should look out for

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

• Severe abdominal pain
• Blood in your vomit or stool
• Signs of dehydration, like not urinating, extreme thirst, very dry mouth and throat, or feeling dizzy when you stand up
• A high fever (over 100.4°F or 38°C)
• Symptoms that last for more than a week
