Handling a Stomach Bug at Home in Brampton: Fluids, Rest and Red Flags

It often starts in the middle of the night. One family member wakes up with cramps and nausea, and before long the vomiting and diarrhea begin. In a busy Brampton household, especially one with young children, grandparents and working adults under the same roof, a stomach bug can work its way through the whole family in a matter of days.

Most cases of what people call “stomach flu” are caused by viruses, such as norovirus, and are not related to influenza at all. Food poisoning from bacteria or toxins in food causes similar symptoms. For healthy adults, these illnesses are usually unpleasant but short, often improving within one to three days. The main risk is dehydration, particularly for young children, older adults and people with chronic health conditions.

This article explains how to manage a stomach bug at home, how to prevent dehydration, which medicines to be careful with, how to protect others, and when to seek help. The pharmacists at Pharmasave WestBram on Pertosa Drive can help you choose rehydration products and check whether your usual medicines need attention while you are sick.

What usually causes a stomach bug

Common causes of sudden vomiting and diarrhea include:

• Norovirus, a very contagious virus that spreads through contaminated hands, surfaces, food and water, and is common in late fall through early spring
• Rotavirus, which mostly affects young children, though routine infant vaccination has reduced cases
• Food poisoning from bacteria such as Salmonella, Campylobacter or E. coli, or toxins in food that was not stored or cooked properly

Viral stomach bugs usually begin suddenly with nausea, vomiting, watery diarrhea and stomach cramps, sometimes with a low fever, headache and body aches. Food poisoning may start within hours to days of eating contaminated food, depending on the cause.

Preventing dehydration comes first

Vomiting and diarrhea cause the body to lose water and important salts called electrolytes. Replacing them is the most important part of home care.

Some practical tips:

• Start with small, frequent sips. After vomiting, wait a little, then try a teaspoon or a small sip every few minutes. Gradually increase as you tolerate it.
• Use oral rehydration solutions for moderate fluid losses, especially for children and older adults. These contain a balanced mix of water, salts and sugar designed to help the body absorb fluid.
• Water is fine for mild cases in otherwise healthy adults, along with clear broths.
• Avoid very sugary drinks, such as undiluted juice, pop and many sports drinks, which can sometimes make diarrhea worse, especially in children.
• Avoid alcohol and limit caffeine while recovering.

Oral rehydration products are available at the pharmacy as ready-to-drink liquids, powders and freezer pops, which children often accept more easily. Follow the label directions for preparation; do not dilute or concentrate them differently than instructed.

Signs of dehydration to watch for

Check for these signs, particularly in children and older adults:

• Passing very little urine, or dark urine
• Dry mouth, lips and tongue
• No tears when crying (in children)
• Sunken eyes
• Unusual sleepiness, irritability or confusion
• Dizziness, especially on standing
• In babies, fewer wet diapers or a sunken soft spot on the head

If these signs appear, increase fluids and seek medical advice. Severe dehydration needs urgent care.

Eating again after the worst is over

There is no need to stop eating for long. Once vomiting has settled, start with small portions of plain, easy-to-digest foods as you feel ready, such as:

• Rice, plain khichdi or congee
• Toast, crackers or plain roti
• Bananas and applesauce
• Plain potatoes
• Soup or broth
• Yogurt, if tolerated

Gradually return to your normal diet over a day or two. Very fatty, spicy or heavy foods may be harder to tolerate at first. For babies, continue breastfeeding or formula feeding, and follow the advice of your healthcare provider.

Medicines to use carefully

Several over-the-counter medicines are sold for nausea and diarrhea, but they are not suitable for everyone:

• Antidiarrheal medicines may help adults with mild diarrhea who need relief, such as for work or travel. They should generally be avoided if there is blood in the stool, a high fever or suspected bacterial food poisoning, and they are not recommended for young children unless a healthcare provider advises.
• Bismuth-containing products may help some symptoms but contain a salicylate, which is not suitable for children and teens recovering from viral illnesses, or for people who are allergic to ASA or take blood thinners. They can also temporarily turn the tongue and stool black.
• Anti-nausea medicines vary in suitability depending on age and health conditions.

Follow the label directions and ask your pharmacist before using these products, especially for children, older adults, during pregnancy or if you take other medicines. For nausea and vomiting in pregnancy specifically, see our pregnancy nausea page.

A “sick day” plan for regular medicines

If you take medicines for chronic conditions, a stomach bug can create special risks. When you are vomiting, have diarrhea and cannot keep fluids down, some medicines can increase the risk of dehydration-related kidney problems or low blood sugar. Examples can include certain diabetes medicines, some blood pressure medicines, diuretics and some anti-inflammatory pain relievers.

Never stop a prescription on your own, but talk to your pharmacist or prescriber about whether you should have a written sick day plan that tells you what to do in this situation. People with diabetes should monitor blood sugar more often when sick and follow the plan they have worked out with their healthcare team. Our diabetes support service can help with this. A medication review is a good time to set up a sick day plan; ask whether you qualify.

If you have vomited shortly after taking a medicine, ask the pharmacist whether to take another dose. The answer depends on the medicine.

Stopping the spread at home

Viral stomach bugs like norovirus spread very easily. Even a tiny amount of virus can make someone sick, and it can survive on surfaces for days. To protect others in your household:

• Wash hands thoroughly with soap and water for at least 20 seconds after using the toilet, changing diapers, cleaning up and before preparing food. Alcohol-based hand sanitisers are less effective against norovirus than soap and water.
• Clean contaminated surfaces promptly with a bleach-based household cleaner, following product directions. Wear disposable gloves.
• Wash soiled laundry on a hot cycle and dry thoroughly.
• Avoid preparing food for others while sick and for at least 48 hours after symptoms stop.
• Use a separate bathroom for the sick person if possible.
• Do not share towels, utensils or cups.

Stay home from work, school or daycare until at least 48 hours after symptoms have stopped, or as your workplace or school advises. This matters especially for people who work in food handling, health care, child care and long-term care. Peel Public Health provides information on infectious diseases and when to stay home.

When to get medical help

Seek medical care if you or a family member has:

• Signs of moderate or severe dehydration
• Vomiting that prevents keeping any fluids down for many hours
• Blood in the vomit or stool, or black stools
• High fever
• Severe abdominal pain, or pain concentrated in one area
• Symptoms lasting more than a few days, or diarrhea lasting more than a week
• A stiff neck, confusion or severe headache
• A weakened immune system, or significant chronic illness

Babies, young children, pregnant people and older adults should be assessed sooner. Call 911 for signs of severe illness, such as fainting, difficulty breathing or unresponsiveness. Ontario residents can also call Health811 for health advice.

Stock a small recovery kit before you need it

It helps to have a few items at home before illness strikes: oral rehydration solution, a thermometer, disposable gloves, a bleach-based cleaner, and plain foods like crackers and rice. If you prefer not to leave home while sick, ask about our home delivery service.

Prevention in the kitchen also reduces the chance of food poisoning. Keep raw meat, poultry and fish separate from ready-to-eat foods, use a separate cutting board for them, and cook them thoroughly. Refrigerate leftovers promptly rather than leaving large pots of curry, rice or stew on the stove to cool for hours, which is common after big family meals and gatherings. Reheat leftovers until steaming hot, and when in doubt about how long something has been sitting out, it is safer to throw it away. Rice in particular should be cooled quickly and refrigerated if it will not be eaten right away.
