Abdominal pain, diarrhea, and fever?


Hello Dr.
Hsu, I have been experiencing abdominal pain (around the central abdomen) and diarrhea (which occurs shortly after eating), accompanied by fever for the past three days.
Could you please tell me what type of gastrointestinal disease this might be? The Western medicine clinic only referred to it as a "viral cold," and the medication only addresses the fever, but the diarrhea persists.

Based on your description, the most likely diagnosis is acute gastroenteritis.
Most patients can recover on their own (or with a small amount of medication).
However, special infections of the gastrointestinal tract, irritable bowel syndrome, or intestinal tumors should all be included in the differential diagnosis.
It is advisable to first test the stool for inflammatory cells or occult blood before proceeding with further diagnosis.

Hello! It sounds like you're experiencing a challenging combination of symptoms: abdominal pain, diarrhea, and fever. These symptoms can indeed be indicative of various gastrointestinal issues, and it's important to consider a few potential causes.

Given that your symptoms have persisted for three days, and you are experiencing diarrhea shortly after eating, this could suggest an infectious cause, such as viral gastroenteritis, commonly referred to as a "stomach virus." This condition is often characterized by sudden onset of diarrhea, abdominal cramps, nausea, and sometimes fever. It is typically self-limiting, meaning it resolves on its own within a few days, but it can be uncomfortable and lead to dehydration, especially if diarrhea is severe.

Another possibility is bacterial gastroenteritis, which can occur after consuming contaminated food or water. Symptoms can be similar to viral gastroenteritis but may be more severe and last longer. If there is a history of recent travel, eating out, or consuming undercooked food, this could be a significant factor. In some cases, specific bacteria like Salmonella, E. coli, or Campylobacter can cause these symptoms, and they may require antibiotic treatment if the infection is severe.

Additionally, food intolerances or allergies can lead to gastrointestinal symptoms, including abdominal pain and diarrhea. If you've recently introduced new foods into your diet, this could be a factor. Conditions like lactose intolerance or celiac disease can also present with similar symptoms, although they typically do not cause fever.

It's also worth considering inflammatory bowel diseases (IBD) such as Crohn's disease or ulcerative colitis, especially if you have a history of similar symptoms or if there are other concerning signs like weight loss, blood in the stool, or persistent symptoms lasting more than a few days. These conditions often require more extensive evaluation, including imaging studies or endoscopy.

Given that you mentioned that a Western medicine clinic diagnosed you with "heat cold" and provided medication only for fever, it may be beneficial to seek a second opinion, especially if your symptoms are not improving. A thorough evaluation by a gastroenterologist may be warranted, including stool tests to check for pathogens, blood tests to assess for inflammation or infection, and possibly imaging studies to rule out other conditions.

In the meantime, it's crucial to stay hydrated, especially if you are experiencing diarrhea. Oral rehydration solutions can help replace lost fluids and electrolytes. Avoiding dairy products, high-fat foods, and overly spicy or rich foods may also help alleviate your symptoms until you can get a more definitive diagnosis.

In summary, while your symptoms could be due to a viral or bacterial infection, other gastrointestinal issues should also be considered. If your symptoms persist or worsen, please seek medical attention promptly to ensure you receive the appropriate care and treatment.
