Acute Gastroenteritis: Symptoms, Recovery, and Dietary Tips

Acute gastroenteritis

Hello doctor, last Monday I had a high fever and went to the emergency room.
At that time, I had no symptoms, and the rapid test was inconclusive, but the doctor still prescribed Tamiflu.
Later, my fever even rose above 39 degrees Celsius.
Starting early Monday morning, I began experiencing diarrhea, going to the bathroom nearly ten times a day.
The fever started to subside on Tuesday, and on Wednesday and Thursday, I still had diarrhea more than seven or eight times.
Upon follow-up, the doctor suspected it was caused by acute gastroenteritis.
Over the weekend, my condition improved, and I went about three to five times a day.
Today is Monday, and although I saw formed stools twice, the other three times were still loose and mixed with soft stools.
I have started eating normally, with a lighter diet, but since school life inevitably involves classmates sharing snacks, I couldn't resist eating a few bites.
When can I expect my stools to return to normal? Should I still avoid dairy, eggs, and beans? Thank you.

A low-fat, dairy-free diet, combined with medication treatment, is sufficient.

More Info

Acute gastroenteritis is an inflammation of the stomach and intestines that can lead to symptoms such as diarrhea, vomiting, abdominal pain, and fever. Your experience of high fever followed by diarrhea aligns with common presentations of this condition. The recovery process can vary significantly among individuals, but there are several key points to consider regarding symptoms, recovery, and dietary recommendations.

Symptoms and Recovery
In your case, the initial high fever and subsequent diarrhea are typical signs of acute gastroenteritis, which can be caused by viral or bacterial infections. The fact that your symptoms have started to improve, with a reduction in the frequency of diarrhea, is a positive sign. It is common for bowel movements to remain irregular for a period after the acute phase of the illness has resolved. You may notice that your stools are still softer or more frequent than usual, which can last for several days to weeks as your digestive system recovers.

Typically, the recovery timeline can vary. While some individuals may return to normal bowel habits within a few days, others may take longer, especially if they have experienced significant gastrointestinal distress. It is essential to stay hydrated and monitor your symptoms closely. If you notice any signs of dehydration (such as dry mouth, decreased urination, or dizziness), it is crucial to seek medical attention.

Dietary Recommendations
Regarding your dietary choices, it is wise to continue with a bland diet as your digestive system heals. Foods that are easy to digest and low in fat are recommended. The BRAT diet (bananas, rice, applesauce, and toast) is often suggested for those recovering from gastroenteritis. These foods are gentle on the stomach and can help firm up stools.

You mentioned that you have been tempted to eat snacks offered by classmates. While it is understandable to want to indulge, it is advisable to avoid certain foods that can irritate your stomach or exacerbate diarrhea. Here are some dietary tips:
1. Avoid Dairy Products: After an episode of gastroenteritis, many individuals experience temporary lactose intolerance. Dairy can be hard to digest and may worsen diarrhea. It is best to avoid milk, cheese, and other dairy products until you are fully recovered.

2. Limit Fatty and Fried Foods: High-fat foods can be difficult for your stomach to process and may lead to further discomfort or diarrhea.

3. Stay Away from Spicy and Acidic Foods: These can irritate the gastrointestinal tract and should be avoided during recovery.

4. Hydration is Key: Continue to drink plenty of fluids, especially water and oral rehydration solutions, to replenish lost fluids and electrolytes.

5. Introduce Foods Gradually: As you start to feel better, you can gradually reintroduce other foods into your diet. Start with bland, low-fiber foods and slowly add in more complex foods as tolerated.

Conclusion
In summary, while your symptoms are improving, it is essential to be patient with your recovery. Your bowel movements may take some time to return to normal, and it is advisable to avoid dairy, fatty, spicy, and acidic foods during this period. If your symptoms persist or worsen, or if you have concerns about your recovery, it is important to consult with a healthcare professional for further evaluation and guidance. Remember, your body needs time to heal, and taking care of your gastrointestinal health is crucial during this recovery phase.
