Why do I get diarrhea every time I eat food outside?

Diarrhea refers to loose bowels. Experiencing diarrhea after eating food from outside can be attributed to improper diet, acute gastroenteritis, gastrointestinal dysfunction, bacillary dysentery, irritable bowel syndrome, among other reasons. It is advisable to seek medical attention promptly and follow the doctor's instructions for corresponding improvements or treatments. Details are as follows:

1. Improper Diet:

If the food eaten outside is spicy or consumed too quickly, it may irritate the gastric mucosa, leading to diarrhea. This is usually transient and does not require treatment. Maintaining good dietary habits and avoiding frequent dining out is recommended.

2. Acute Gastroenteritis:

After consuming food from outside, if the intestines are infected by bacteria, viruses, or other pathogens, it may trigger acute gastroenteritis, manifesting as nausea, vomiting, and diarrhea. Treatment can include medications such as Compound Berberine Tablets, Norfloxacin Capsules, and Vitamin B6 Tablets, administered under a doctor's supervision.

3. Gastrointestinal Dysfunction:

Mental stress, improper diet, and gastrointestinal infections can induce gastrointestinal dysfunction, causing abnormal intestinal motility, poor digestion and absorption, and symptoms like diarrhea, abdominal pain, and nausea. Medications like Live Combined Bacillus Subtilis and Enterococcus Faecium Capsules, Bifidobacterium Triple Viable Tablets, and Mosapride Citrate Tablets can be prescribed.

4. Bacillary Dysentery:

Inadvertently consuming food contaminated with shigella bacteria while dining out may lead to bacillary dysentery, characterized by diarrhea, abdominal pain, nausea, belching, and fever. Treatment options include Amoxicillin and Clavulanate Potassium Tablets, Hydrotalcite Tablets, and Amoxicillin Capsules, administered under medical guidance.

5. Irritable Bowel Syndrome (IBS):

Individuals with IBS may experience aggravated symptoms, such as nausea and diarrhea, after consuming food from outside due to gastrointestinal irritation. Medications like Scopolamine Tablets, Raceanisodamine Tablets, and Atropine Tablets can be prescribed.

Additionally, it could also be ulcerative colitis. If symptoms persist, it is essential to seek medical attention for further evaluation. Regular physical adjustments, avoiding inappropriate dietary habits, maintaining a positive mindset, and engaging in appropriate physical activities are also crucial.
