Gastrointestinal issues


Hello Doctor, I would like to ask about something that happened to me yesterday.
Before going to bed, I suddenly felt bloated in my stomach.
I managed to fall asleep, but I woke up in the middle of the night feeling uncomfortable and had to have a bowel movement.
It wasn't watery, but it was loose, and I felt a bit nauseous, almost to the point of vomiting, but I decided not to since it was late.
I took a medication called Yiwei tablet and Yifuning, which I had previously received from my internist when I was worried about sudden abdominal pain.
They arranged for a stool occult blood test, which came back negative.
After taking the medication, I went back to sleep.
This morning, I had a bowel movement, but it was formed and not loose.
Currently, I don't feel nauseous, but I keep passing gas, and occasionally my stomach makes gurgling sounds.

I would like to know what this situation generally indicates.
I'm wondering if it could be food poisoning or gastroenteritis since I ate out for two meals yesterday.
I recall seeing news about norovirus recently.
The clinic is closed today, and I plan to visit tomorrow, Monday.
Could you please advise me on what might be happening or what I should do in the meantime? I read online that I shouldn't take antacids because it might prevent bacteria from being expelled, which could lead to perforation, and that sounds quite alarming.
Additionally, do you think I need to undergo an endoscopy? After my last visit, where the report was negative, the doctor mentioned that I didn't need one.
Thank you, Doctor, and I apologize for bothering you during your time off.

Hello, based on your description, it seems to be acute gastroenteritis.
As for whether it is caused by norovirus, testing may be needed to confirm.
However, the management typically involves a bland diet, plenty of rest, and increased fluid intake, which should lead to gradual improvement.
If there is severe abdominal pain, then antacids may be necessary.
Generally, an endoscopy is only indicated in cases of gastrointestinal bleeding or gastroesophageal reflux disease.
Thank you for your inquiry.

More Info


It sounds like you're experiencing a range of gastrointestinal symptoms that can be quite distressing. Based on your description, it seems you had an episode of abdominal discomfort, followed by loose stools and some nausea. You also mentioned that you had previously undergone tests that ruled out serious conditions, which is reassuring.

From what you've described, there are a few potential explanations for your symptoms. One possibility is that you may have experienced a mild case of gastroenteritis, which is often caused by viral infections (like norovirus, which you mentioned) or sometimes by bacterial infections from contaminated food. Symptoms of gastroenteritis can include abdominal pain, diarrhea, nausea, and sometimes vomiting. The fact that you had loose stools and some abdominal discomfort aligns with this possibility.

Another consideration is that your symptoms could be related to dietary choices, especially if you've been eating out frequently. Foods that are rich in fats, spices, or that are not prepared in a hygienic manner can sometimes lead to gastrointestinal upset. Additionally, if you have a history of irritable bowel syndrome (IBS) or other functional gastrointestinal disorders, stress or certain foods can trigger symptoms like bloating, gas, and changes in bowel habits.

Regarding your concern about taking medications like antacids or other gastrointestinal drugs, it's important to note that while these medications can provide relief, they may also mask symptoms that could indicate a more serious condition. If your symptoms are mild and improving, it may be reasonable to monitor your condition for a short period. However, if you experience worsening symptoms, persistent nausea, vomiting, high fever, or blood in your stool, you should seek medical attention promptly.

As for the need for an endoscopy (gastroscopy), this is typically reserved for cases where there are persistent symptoms that do not respond to treatment, or if there are concerning signs that warrant further investigation. Since your previous tests were negative and you are currently feeling better, it may not be necessary at this time. However, if your symptoms return or worsen, discussing this with your healthcare provider would be a good idea.

In the meantime, here are some general recommendations to help manage your symptoms:
1. Stay Hydrated: Make sure to drink plenty of fluids, especially if you have had diarrhea. Oral rehydration solutions can be beneficial.

2. Dietary Adjustments: Stick to a bland diet for a few days, such as bananas, rice, applesauce, and toast (the BRAT diet). Avoid spicy, fatty, or heavy foods until you feel better.

3. Monitor Symptoms: Keep track of your symptoms, including any changes in bowel habits, pain levels, or the presence of any new symptoms.

4. Rest: Ensure you get adequate rest, as fatigue can exacerbate gastrointestinal symptoms.

5. Seek Medical Attention: If symptoms persist or worsen, or if you have any concerns about your health, do not hesitate to consult a healthcare professional.

In conclusion, while your symptoms may be indicative of a mild gastrointestinal issue, it's essential to listen to your body and seek medical advice if things do not improve. Your health is paramount, and it's always better to err on the side of caution when it comes to gastrointestinal symptoms.
