When experiencing stomach ache and loose motions, and after taking Pantop D (which helps reduce stomach acid and improve motility), it's important to manage symptoms carefully. You might consider:

• Hydration: Drink plenty of fluids to prevent dehydration from loose motions.
• Oral Rehydration Salts (ORS): These can help replace lost electrolytes.
• Antidiarrheal medications: Medicines like loperamide can reduce diarrhea but should be used cautiously and not if you have fever or blood in stools.
• Probiotics: These may help restore gut flora balance.

However, if symptoms persist beyond 2 days, worsen, or are accompanied by high fever, severe pain, or blood in stools, you should seek medical attention promptly. Avoid self-medicating with multiple drugs without professional advice, as the cause of symptoms could be infection or other conditions requiring specific treatment.

Please consult a gastroenterologist for a thorough evaluation and appropriate treatment.
