Acute Gastroenteritis or Norovirus? Your Symptoms and Treatment

Acute gastroenteritis? Norovirus?

Hello Doctor: On March 5th around 11 PM, I experienced severe cramping pain in my lower abdomen (similar to the sensation of intestinal twisting).
This was followed by diarrhea; from the night of March 5th to the morning of March 6th, I had about 5-6 bowel movements.
Initially, it was diarrhea with a semi-liquid consistency, which later progressed to watery stools.
On the morning of March 6th, I visited a gastroenterologist who prescribed the following medications (strocain, kascoal, spastec, biotase, imodium) but did not specify whether it was a case of general gastroenteritis or norovirus (I had fish for lunch on March 5th and am unsure if it was spoiled).
Throughout March 6th, the pain shifted to my upper abdomen (stomach), and any food or water intake would lead to bowel movements approximately 1-2 hours later (watery stools), including when taking medication with water.
The anti-diarrheal medication imodium also did not seem to help, as I continued to have watery stools.
I have been eating very little throughout the day.
Currently, I do not have a fever, nausea, or vomiting, but I am experiencing belching, stomach rumbling, and excessive flatulence.
I would like to ask the doctor if, given my current condition, it would be better to fast and only replenish with electrolytes, as even drinking water triggers diarrhea.
Thank you for your response, Doctor!

There is no specific antiviral medication for norovirus; treatment is generally based on symptom management, similar to that for general gastroenteritis.
The treatment approach includes fasting, replenishing fluids and electrolytes, and using medications to control symptoms.
It is also important to ensure proper disinfection of the environment, such as toilets.

More Info

Based on your symptoms and the timeline you've provided, it appears that you may be experiencing acute gastroenteritis, which could be caused by a viral infection such as norovirus, especially considering your recent consumption of fish. Acute gastroenteritis is characterized by inflammation of the stomach and intestines, leading to symptoms such as abdominal pain, diarrhea, and sometimes vomiting. In your case, the absence of fever, nausea, or vomiting is noteworthy, but the persistent diarrhea and abdominal discomfort are significant.

Norovirus is a common cause of gastroenteritis and is highly contagious. It often spreads through contaminated food or water, or by coming into contact with surfaces contaminated with the virus. Symptoms typically include sudden onset of diarrhea, vomiting, nausea, and stomach cramps. The fact that you experienced intense abdominal pain followed by diarrhea aligns with this. However, other viral or bacterial infections could also present similarly, making it difficult to pinpoint the exact cause without further testing.

Regarding your treatment, the medications prescribed (strocain, kascoal, spastec, biotase, and imodium) are commonly used to manage symptoms of gastroenteritis. However, it's important to note that Imodium (loperamide) is generally not recommended in cases of suspected viral gastroenteritis, especially if there is a high fever or blood in the stool, as it can prolong the infection by slowing down the elimination of the virus from your system.

In terms of dietary recommendations, if you are experiencing frequent watery diarrhea, it is advisable to temporarily avoid solid foods and focus on rehydration. Oral rehydration solutions (ORS) are ideal as they help replenish lost fluids and electrolytes. You should aim to sip on clear fluids such as water, broth, or diluted sports drinks. If you find that even water triggers diarrhea, you might want to try taking small sips or ice chips to see if that helps.

As for fasting, it can be beneficial in the short term to allow your gastrointestinal tract to rest. However, complete fasting is not necessary; instead, focus on hydration and gradually reintroducing bland foods as your symptoms improve. Foods like bananas, rice, applesauce, and toast (the BRAT diet) are often recommended once you can tolerate liquids without triggering diarrhea.

If your symptoms persist beyond a few days, worsen, or if you develop new symptoms such as high fever, severe abdominal pain, or signs of dehydration (such as dizziness, dry mouth, or decreased urination), it is crucial to seek medical attention promptly. In some cases, further evaluation may be necessary to rule out other conditions or complications.

In summary, while your symptoms are consistent with acute gastroenteritis, possibly due to norovirus, careful monitoring and supportive care are essential. Focus on hydration, consider a temporary diet of clear liquids, and avoid medications that may hinder recovery unless advised by a healthcare professional. If your condition does not improve or worsens, do not hesitate to consult a physician for further evaluation and management.
