Nausea and gastrointestinal issues?


Hello Doctor: Last week, I went to a night market and ate some food (egg cake, quail eggs, and fried chicken leg).
After returning, I felt nauseous and wanted to vomit.
The next day, I went to see a doctor who diagnosed me with gastritis and prescribed medication.
Now that I have finished the medication, my symptoms have improved, but I still experience some nausea, a desire to vomit, and mild stomach pain (I have had similar issues before and have undergone an endoscopy and taken medication).
During this time, I have avoided fried foods, snacks, sweets, and only consumed fruits (but not sour ones).
I have yogurt for breakfast and drink black tea.
I would like to ask why, despite having a light diet, I still experience these symptoms.
Are there any foods I should avoid?

It may take some time to recover, and medication can be taken again if necessary.
If you consume food that causes discomfort, take a break from eating.

More Info


Understanding nausea and gastrointestinal issues after eating can be quite complex, especially when considering the various factors that can contribute to these symptoms. Based on your description, it seems that you have experienced nausea, vomiting, and mild stomach pain after consuming certain foods, particularly after a visit to a night market where you indulged in fried and potentially greasy foods. Your doctor diagnosed you with gastritis and prescribed medication, which has helped alleviate some of your symptoms, but you are still experiencing lingering nausea and discomfort.

Gastritis, which is the inflammation of the stomach lining, can be triggered by a variety of factors, including diet, stress, and certain medications. In your case, the consumption of fried foods and other rich items may have exacerbated your condition. Fried foods are often high in fat and can be difficult for the stomach to process, leading to increased gastric irritation and symptoms such as nausea and pain. Additionally, if you have a history of gastritis or other gastrointestinal issues, your stomach may be more sensitive to certain foods.

Even though you have switched to a lighter diet, including fruits and yogurt, it is important to recognize that some foods can still provoke symptoms. For instance, while yogurt is generally considered beneficial for gut health due to its probiotics, some individuals may find that dairy products can trigger discomfort, especially if they are lactose intolerant or sensitive. Similarly, certain fruits, particularly those that are acidic (like citrus fruits), can irritate the stomach lining and should be avoided during flare-ups.

To manage your symptoms effectively, consider the following dietary recommendations:
1. Avoid Trigger Foods: Steer clear of fried, greasy, and spicy foods, as well as acidic fruits and beverages (like citrus and coffee). Processed foods, sugary snacks, and carbonated drinks can also contribute to gastrointestinal discomfort.

2. Incorporate Gentle Foods: Focus on bland, easy-to-digest foods such as plain rice, boiled potatoes, bananas, applesauce, and oatmeal. These foods can help soothe the stomach and reduce irritation.

3. Stay Hydrated: Drink plenty of water throughout the day. Herbal teas (like ginger or chamomile) can also be soothing for the stomach.

4. Eat Smaller, Frequent Meals: Instead of three large meals, try eating smaller portions more frequently. This can help reduce the burden on your stomach and minimize symptoms.

5. Monitor Your Symptoms: Keep a food diary to track what you eat and how it affects your symptoms. This can help you identify specific foods that may trigger discomfort.

6. Consult Your Doctor: Since your symptoms persist even after dietary changes, it may be beneficial to follow up with your healthcare provider. They may recommend further evaluation, such as an endoscopy, to assess the condition of your stomach lining or to rule out other potential issues.

7. Consider Stress Management: Stress can significantly impact gastrointestinal health. Techniques such as mindfulness, meditation, or gentle exercise may help alleviate stress and improve your overall well-being.

In conclusion, while you have made commendable efforts to adjust your diet in response to your symptoms, it is essential to remain vigilant about what you consume and to seek further medical advice if your symptoms do not improve. Gastritis can be a chronic condition, and managing it often requires a combination of dietary changes, medication, and lifestyle adjustments. Always consult with your healthcare provider before making significant changes to your diet or treatment plan.
