Key takeaways

Stomach infections (gastroenteritis) are commonly caused by contaminated food or water.
The primary goal is maintaining electrolyte balance using ORS and clean fluids.
Incorporate the BRAT diet (Bananas, Rice, Applesauce, Toast) and fresh dahi.
Avoid milk, fatty foods, carbonated drinks, and raw salads.

Stomach infection, also known as gastroenteritis or food poisoning, is an inflammation of the stomach and intestines caused by viruses, bacteria, or parasites. In Kanpur, eating street food or drinking contaminated water during summers and monsoons frequently leads to stomach infections. Recovery relies heavily on hydration and resting the gut.

Best Foods for Stomach Infection Recovery

Rest your gut and restore hydration:

ORS & Rehydration Fluids: Drink ORS water, coconut water, or clean salted buttermilk to replenish lost minerals.
Dahi-Chawal: Fresh curd supplies active probiotics to fight infection, while white rice is easy to digest.
Bananas: Soft on the stomach and rich in potassium to prevent weakness.
Moist Toast or Cream of Wheat (Suji Dalia): Bland carbohydrates that are easy to absorb.

Foods to Avoid During Infection

Avoid items that can trigger vomiting or diarrhea:

Dairy Milk: Gut lining damage makes it temporarily hard to digest lactose, worsening diarrhea.
Fried & Spicy Foods: Intestinal walls are raw; oil and spices will cause immediate cramping.
Raw Vegetables: Raw fiber requires heavy digestive work.

When to Consult a Gastroenterologist?

Most stomach infections resolve in 2-3 days. However, severe infections require clinical diagnosis and antibiotics.

WARNING: If you cannot keep fluids down for 24 hours, have a high fever, notice blood in your vomit or stool, or experience signs of severe dehydration (dizziness, dark urine), seek urgent medical care.

Get evaluated by Dr. Vikas Sengar at Medi Help Hospital, Kanpur, for professional diagnosis and intravenous hydration if required.

Frequently Asked Questions (FAQs)

Q1: Should I stop eating completely during a stomach infection?
No. While you should avoid heavy foods, keeping yourself hydrated and eating small amounts of bland food (rice, toast) supports recovery.

Q2: Are probiotic drinks helpful?
Yes, probiotics help restore the healthy bacteria in your gut that may have been flushed out during infection.

Q3: Can I take antibiotics directly?
No, taking antibiotics without a doctor's advice is unsafe as they can disrupt gut flora and are ineffective against viral infections.
