Here is a clear, practical guide on what to eat (and avoid) when you have diarrhea:
What to Eat During Diarrhea
The BRAT Diet - Your Foundation
These four foods are the go-to starting point because they are bland, low in fiber, and help firm up loose stools:
| Food | Why it helps |
|---|---|
| Bananas | Rich in potassium (replaces lost electrolytes); starch helps absorb water in the colon |
| Rice (white) | Easy to digest; white rice is better than brown during diarrhea |
| Applesauce (unsweetened) | Gentle on the gut; pectin (a soluble fiber) helps slow things down |
| Toast (white bread) | Bland and binding; white bread is easier on the stomach than whole grain |
Other Safe Foods to Add
Starchy/bland foods:
- Oatmeal (plain, not sugary)
- Plain crackers (like saltines)
- Mashed or boiled potatoes (peeled, no butter or cream)
- Plain white pasta or noodles
- Plain boiled rice soup (congee)
Protein sources (low fat):
- Boiled or baked chicken (no skin)
- Boiled or baked fish (lean varieties)
- Eggs (boiled or scrambled, no butter)
- Smooth peanut butter in small amounts
- Plain low-fat yogurt (the live cultures may help restore gut flora)
- Firm tofu
Cooked vegetables (soft/blended):
- Mashed squash, yams, carrots
- Clear vegetable soup
- Well-cooked, peeled vegetables
Staying Hydrated - Critically Important
Diarrhea causes rapid fluid and electrolyte loss. Aim to drink small sips frequently:
- Water (plain, at room temperature)
- Clear broth (chicken or vegetable soup) - replaces sodium and potassium
- Oral Rehydration Solution (ORS) - best for significant fluid loss (especially in children and the elderly)
- Diluted sports drinks (like Gatorade) - though they can be high in sugar
- Weak, unsweetened tea (decaffeinated)
- Coconut water - natural source of electrolytes
Eat 5-6 small meals throughout the day rather than 3 large ones - this is much easier on the gut.
Foods to AVOID
| Category | Examples |
|---|---|
| High-insoluble fiber | Whole grains, nuts, seeds, raw vegetables, bran, popcorn |
| Dairy | Milk, cream, ice cream (lactose can worsen diarrhea) - plain yogurt is often okay |
| Fatty/greasy/fried foods | Fast food, deep-fried anything, high-fat meats |
| Spicy foods | Chili, hot sauces, heavily seasoned dishes |
| High-sugar foods | Fruit juice, soda, chocolate milk, candy |
| Sugar alcohols | Sorbitol, mannitol, xylitol (found in sugar-free gum and candy) - these actively cause diarrhea |
| Caffeine | Coffee, energy drinks, strong tea |
| Alcohol | Worsens dehydration and gut irritation |
| Citrus fruits | Oranges, lemons, grapefruit |
| Carbonated drinks | Soda, sparkling water |
When to See a Doctor
Seek medical attention if you notice:
- Diarrhea lasting more than 2 days in adults (or 24 hours in children/infants)
- Signs of dehydration: dry mouth, dizziness, no urination, sunken eyes
- Blood or mucus in the stool
- High fever
- Severe abdominal pain
Key principle: Eat soft, low-fiber, low-fat, bland foods. Avoid anything that stimulates or irritates the gut. Prioritize fluids and electrolytes above everything else - dehydration is the main danger of diarrhea, especially in children and older adults.
like in my hostel 4 people already have diarrhoea and got admitted in hostel
This sounds like a disease outbreak - 4 people in the same hostel getting diarrhea at the same time strongly suggests a common source infection (contaminated food or water).
This is a public health emergency. Act now.
🚨 Immediate Steps
1. Report It
- Tell hostel warden/management immediately - they must investigate the food/water source
- Contact your local health authority or municipal health officer - cluster outbreaks are legally reportable
- If you're in a college hostel, notify the college medical officer
2. Stop Eating from the Common Source
- Stop eating hostel food until the source is identified
- Stop drinking tap water - switch to sealed bottled water only
- Do not share utensils, water bottles, or food with others
3. If YOU have symptoms
- Go to a doctor/hospital today - don't wait
- Common culprits in hostel outbreaks: Salmonella, E. coli, Vibrio cholerae, Norovirus, Shigella
- These can get serious fast, especially cholera
What Likely Happened
| Possible Source | Signs |
|---|---|
| Contaminated drinking water | Everyone drinks same water |
| Mess/canteen food (undercooked, stored badly) | People who ate same meal got sick |
| Infected food handler | Cook/server with infection touched food |
| Poor sanitation in kitchen | Fecal-oral route spread |
While Waiting / If Mild Symptoms
- Drink ORS (Oral Rehydration Salt) sachets - available at any pharmacy, very cheap
- Mix 1 ORS sachet in 1 litre of sealed bottled water
- Sip continuously - do not gulp
- Eat only: plain rice, bananas, plain crackers, boiled potato
- Avoid hostel food entirely for now
⚠️ Go to Hospital Immediately If You See
- Watery diarrhea more than 3 times in an hour (could be cholera)
- Rice-water stools (thin, pale, large volume - classic cholera sign)
- Vomiting + diarrhea together (fast dehydration)
- Muscle cramps, weakness, dizziness
- No urination for several hours
The fact that 4 people are already hospitalized means this is serious. Even if you feel fine right now, avoid all common food/water sources in the hostel until the outbreak source is found and fixed. Your priority is prevention and early hydration if any symptoms start.

Here is a practical breakdown, keeping in mind your hostel outbreak situation:
⚠️ Important First
Since this is a cluster outbreak (4+ people from the same place), the doctor treating the hospitalized people likely already knows the cause. Call them or go to the same hospital - they can tell you exactly which antibiotic is needed. Taking the wrong one wastes time.
What You Can Take Right Now (Before Seeing a Doctor)
1. ORS - Most Important Medicine
Oral Rehydration Salts (ORS) - this is your #1 priority, not antibiotics.
- Buy Electral, Enerlyte, or any ORS sachet from a pharmacy
- Mix 1 sachet in 1 litre of sealed bottled water
- Sip slowly throughout the day even if you feel okay - it prevents dehydration
- Cost: Rs. 5-15 per sachet, available everywhere
2. Zinc (If Under 5 Years or Child)
- 20 mg/day for 10-14 days in children
- Reduces severity and duration of diarrhea
Medicines for Symptom Relief (Short Term)
| Medicine | What it Does | Caution |
|---|---|---|
| Loperamide (Imodium) | Slows gut motility, reduces frequency | Do NOT use if you have fever or blood in stool - it can trap bacteria inside |
| Racecadotril (Hidrasec) | Reduces fluid secretion in gut, safer than loperamide | Preferred in infectious diarrhea |
| ORS + Zinc | Rehydration | Always safe |
Antibiotics - Only If Prescribed
Do not self-prescribe antibiotics. But in a hostel outbreak, doctors commonly use:
| Bacteria Suspected | Antibiotic Typically Used |
|---|---|
| Cholera (Vibrio cholerae) | Doxycycline 300mg single dose OR Azithromycin |
| Shigella / E. coli | Ciprofloxacin OR Azithromycin |
| Salmonella | Ciprofloxacin OR Ceftriaxone (if severe) |
| Giardia / Parasites | Metronidazole (Flagyl) |
The hospitalized patients will have stool tests done - that result will tell the doctor exactly which bug is causing the outbreak, and you can get the right antibiotic.
Right Now, Do This:
- Buy ORS sachets immediately - start drinking
- Call the hospital where the 4 students are admitted - ask what bacteria was found
- See a doctor today - even if your symptoms are mild, get checked given the outbreak
- Do not eat hostel food or drink tap water until cleared
Go to Emergency Immediately If:
- Diarrhea more than 5-6 times in a few hours
- Vomiting so much you can't keep ORS down
- Feeling very weak, dizzy, or faint
- No urination for 6+ hours
- Watery, pale, large-volume stools (cholera sign)
The most dangerous thing about diarrhea in an outbreak is dehydration - ORS can genuinely save your life while you wait to see a doctor.

In your specific situation - multiple people in the same hostel, same time, same food/water source - this is a classic common-source outbreak. Here is what the textbooks and epidemiology point to:
Most Likely Causes - Ranked for Your Situation
🥇 #1 Most Likely: Contaminated Food or Water (Bacterial)
Salmonella - Top suspect in hostel/mess outbreaks
- Source: Undercooked chicken, eggs, rice stored at wrong temperature, creams/mayonnaise
- Onset: 6-48 hours after eating
- Symptoms: Watery diarrhea, fever, vomiting, abdominal cramps
- Severe enough to require hospitalization - matches your situation
Shigella (Bacillary Dysentery)
- Source: Contaminated water or food handled by an infected cook
- Onset: 1-3 days
- Symptoms: Bloody diarrhea, high fever, severe cramps
- Spreads very easily person to person - explains why multiple people are sick
E. coli (ETEC / EHEC)
- Source: Contaminated water, undercooked meat, unwashed vegetables
- ETEC causes large-volume watery diarrhea
- Very common in India and developing countries
Vibrio cholerae (Cholera)
- Source: Contaminated water supply - very important if your hostel water is suspect
- Onset: Hours
- Symptoms: Sudden massive watery diarrhea (rice-water stools), rapid dehydration
- Can hospitalize people very fast - explains the severity
🥈 #2: Norovirus (Viral)
- Source: Infected food handler touching food, contaminated surfaces
- Onset: 12-48 hours
- Symptoms: Sudden vomiting + diarrhea, no blood, low-grade fever
- Spreads explosively in closed settings (hostels, ships, schools)
- Most common cause of outbreak diarrhea worldwide
- No antibiotic needed - self-limiting in 1-3 days
🥉 #3: Staphylococcus aureus or Bacillus cereus (Food Toxin)
- Source: Reheated rice, stored cooked food left out for hours, creamy foods
- Onset: Very fast - 1-6 hours after eating
- Symptoms: Sudden severe vomiting + diarrhea, usually no fever
- If everyone got sick very quickly after the same meal, this is likely
How to Identify the Cause (Clue Chart)
| Clue | Most Likely Bug |
|---|---|
| Sick within 1-6 hours of eating | Staph aureus or B. cereus (preformed toxin) |
| Sick 6-24 hours later, watery diarrhea, fever | Salmonella, E. coli |
| Sick 1-3 days later, bloody diarrhea | Shigella, E. coli O157 |
| Massive watery diarrhea, no fever, rapid weakness | Cholera |
| Vomiting is main symptom, mild diarrhea, no fever | Norovirus |
| Everyone who ate the same dish got sick | Bacterial food poisoning |
| Everyone who drank the water got sick | Cholera, E. coli, Shigella |
Bottom Line for Your Hostel
Given that people are sick enough to be hospitalized, the top suspects are:
- Salmonella from mess food (most common in India in hostel outbreaks)
- Shigella from contaminated water or food handler
- Cholera if the water supply is the source
All three require antibiotics + IV fluids in hospital, which is why the others were admitted. This is exactly why you should not wait - get checked now, and avoid all common food and water in the hostel until the source is confirmed and fixed.
