Diarrhea occurring nearly 20 times?


Hello doctor, I have been experiencing severe diarrhea for the past few days and visited a nearby clinic.
The doctor suspected norovirus and prescribed medication.
After taking the medication and resting at home, I found that I immediately need to use the restroom after drinking water.
Yesterday, I had diarrhea as many as 20 times, and this morning I noticed blood in my stool.
Although I haven't finished the medication, should I go back for a follow-up or go to a larger hospital for further examination? Thank you for your guidance.

Maintain hydration and practice frequent handwashing.

More Info


Severe diarrhea can be a distressing and potentially serious condition, especially when accompanied by symptoms such as blood in the stool, excessive frequency, and dehydration. Based on your description, it appears that your situation has escalated from a suspected viral infection (norovirus) to a more concerning state, particularly with the presence of blood in your stool and the frequency of your bowel movements.

Firstly, it is crucial to understand that diarrhea can be caused by various factors, including infections (viral, bacterial, or parasitic), food intolerances, medications, and underlying health conditions. Norovirus is a common cause of gastroenteritis, leading to symptoms like vomiting, diarrhea, and abdominal cramps. While many cases resolve on their own with supportive care, certain signs indicate the need for further medical evaluation.

Given that you have experienced diarrhea 20 times in a single day and have noticed blood in your stool, it is advisable to seek medical attention promptly. Blood in the stool can be a sign of more severe conditions, such as gastrointestinal bleeding, inflammatory bowel disease, or severe infections that may require specific treatments. Additionally, the fact that you are unable to retain fluids and are experiencing frequent urges to use the restroom raises concerns about dehydration, which can lead to serious complications if not addressed.

Here are some key points to consider when deciding whether to seek further medical attention:
1. Blood in Stool: The presence of blood, even in small amounts, warrants immediate medical evaluation. It is essential to determine the source of the bleeding and whether it poses a risk to your health.

2. Dehydration Symptoms: Signs of dehydration include excessive thirst, dry mouth, decreased urine output, dizziness, and fatigue. If you are unable to keep fluids down or are experiencing these symptoms, you should seek medical care.

3. Duration of Symptoms: If your diarrhea persists for more than 48 hours without improvement, or if it worsens, it is crucial to consult a healthcare provider.

4. Underlying Health Conditions: If you have any pre-existing health issues, such as immunocompromised states, diabetes, or gastrointestinal disorders, you should be more vigilant and seek care sooner.

5. Response to Treatment: If the medications prescribed by your doctor do not seem to alleviate your symptoms or if you experience new symptoms, it is important to follow up.

In your case, since you have already been diagnosed with a suspected viral infection and are experiencing worsening symptoms, it would be prudent to visit a larger hospital or an emergency department for a more comprehensive evaluation. They may perform diagnostic tests, such as blood tests, stool cultures, or imaging studies, to determine the underlying cause of your symptoms and provide appropriate treatment.

In summary, do not hesitate to seek further medical attention given your current symptoms. It is better to err on the side of caution, especially when dealing with potential gastrointestinal issues that could lead to serious complications. Your health and well-being are paramount, and timely intervention can make a significant difference in your recovery.
