Your symptoms of severe stomach pain, repeated vomiting, fever, and loose stools indicate an episode of acute infectious gastroenteritis (May be food poisoning or gut infection).
Because you had a very similar, severe infection requiring IV fluids only 3–4 weeks ago, your intestinal mucosal lining likely never fully healed, leaving your gut sensitive and vulnerable to reinfection or lingering gut inflammation.
The persistent heaviness and inability to keep fluids down put you at immediate risk for dehydration and electrolyte imbalance.
Next Steps
Do not gulp down large amounts of fluids all at once; instead, take small, frequent sips of ORS (one tablespoon every 5–10 minutes) to prevent triggering the vomiting reflex.
Stick strictly to light, bland foods like rice kanji, curd, or toast only when vomiting settles, and completely avoid raw fruits, fruit juices, milk, and oily foods for now.
Please book an online consultation with me immediately so we can prescribe appropriate antiemetics, assess for dehydration, and arrange basic stool and blood tests.
Health Tips
Avoid self-medicating with leftover antibiotics from your previous episode, as inappropriate use will further destroy your beneficial gut flora and worsen diarrhea.
Take proper rest and monitor your urine output to ensure you are passing clear to light-yellow urine at least every 4 to 6 hours.
Go to the nearest emergency room immediately if you cannot keep even sips of water down, notice blood in your vomit or stool, feel extreme dizziness upon standing, or develop high continuous fever.
