Gastroenteritis in Grand Rapids, MI

Gastroenteritis—often called the “stomach flu” (though it’s not actually influenza)—is a common illness in Grand Rapids, especially during fall and winter. It involves inflammation of the stomach and intestines and can affect people of all ages throughout West Michigan.

Typical Symptoms of Gastroenteritis

Typical symptoms of gastroenteritis include:

  • Abdominal cramps or stomach pain
  • Diarrhea (sometimes watery, occasionally bloody)
  • Nausea and vomiting
  • Loss of appetite
  • Bloating or excess gas
  • General feeling of being unwell or “wiped out”
  • Lethargy or fatigue
  • Body aches
  • Low-grade fever (in some cases)

In most healthy adults in Grand Rapids, gastroenteritis improves on its own within a few days. However, dehydration is a serious risk, especially for:

  • Young children
  • Older adults
  • People with chronic conditions (such as diabetes, heart disease, or kidney disease)

If dehydration becomes severe, you may need intravenous (IV) fluids in an emergency department or urgent care at local hospitals such as Corewell Health (formerly Spectrum Health) Butterworth Hospital, Trinity Health Grand Rapids, Metro Health – University of Michigan Health, or Mercy Health facilities.

Causes of Gastroenteritis

Gastroenteritis is usually caused by an infection, but chemicals and medications can also trigger it. In Grand Rapids and across Michigan, common causes include:

Viral Gastroenteritis

Viruses are the most frequent cause of “stomach flu.” Common viruses include:

  • Norovirus (often causes outbreaks in schools, nursing homes, and on cruise ships)
  • Rotavirus (especially in children)
  • Calicivirus
  • Astrovirus
  • Adenovirus

These viruses spread easily from person to person, particularly in closed or crowded environments like:

  • Schools and daycares in Grand Rapids and Kent County
  • Long-term care facilities
  • Workplaces and offices
  • Large family gatherings, especially during the winter holidays

You can catch viral gastroenteritis by:

  • Touching contaminated surfaces, then touching your mouth
  • Sharing utensils, drinks, or food with an infected person
  • Eating food or drinking water contaminated with the virus

Bacterial Gastroenteritis

Certain bacteria can cause gastroenteritis, including:

  • Campylobacter
  • Salmonella
  • Escherichia coli (E. coli)
  • Shigella

These bacteria are often found in:

  • Undercooked or raw meat, especially poultry
  • Unpasteurized milk or dairy products
  • Raw or undercooked eggs
  • Contaminated raw fruits and vegetables
  • Food that has not been kept at safe temperatures

Infection can occur when you:

  • Eat undercooked meat (especially chicken)
  • Eat food that was prepared on contaminated surfaces
  • Handle animals (including farm animals and backyard poultry) and then eat without washing your hands
  • Drink contaminated water (for example, during a boil-water advisory or when camping in Michigan without proper water treatment)

Some bacteria produce toxins (poisonous by-products) that contaminate food. Staphylococcal bacteria, for example, can produce toxins that cause rapid-onset vomiting and diarrhea even if the bacteria themselves are no longer alive in the food.

Parasitic Gastroenteritis

Parasites that can cause gastroenteritis include:

  • Giardia lamblia (giardiasis)
  • Cryptosporidium
  • Entamoeba histolytica

These parasites can be found in the bowels of humans and animals and can contaminate:

  • Lakes, rivers, and pools (a concern in Michigan’s Great Lakes region and inland lakes)
  • Untreated or poorly treated drinking water
  • Surfaces and hands after contact with infected stool

You can become infected by:

  • Accidentally swallowing water while swimming in contaminated pools or lakes
  • Drinking untreated or contaminated water when camping or traveling
  • Changing diapers or cleaning up after an infected child and not washing your hands
  • Handling infected animals and then touching your mouth or food

Non-infectious causes include:

  • Certain medications (such as some antibiotics or NSAIDs) in susceptible people
  • Chemicals or heavy metals (for example, lead poisoning)

If you suspect a chemical or medication is causing your symptoms, contact your healthcare provider or a Grand Rapids poison control resource right away.

Why Identifying the Cause Matters

Different types of gastroenteritis respond to different treatments:

  • Viral infections usually improve on their own with rest and fluids.
  • Bacterial infections may require antibiotics in some cases.
  • Parasitic infections require specific anti-parasitic medications.
  • Medication- or chemical-related causes need the trigger removed and supportive care.

Because of this, it’s important to see a healthcare provider in Grand Rapids if your symptoms are severe, prolonged, or unusual (such as bloody stools or high fever).

Diagnosis of Gastroenteritis in Grand Rapids

Healthcare providers in Grand Rapids may use several methods to diagnose gastroenteritis and rule out other conditions:

  • Medical history – recent travel, food intake, sick contacts, outbreaks at school or work
  • Physical examination – checking for signs of dehydration, abdominal tenderness, or fever
  • Stool tests – to look for viruses, bacteria, parasites, or blood
  • Blood tests – to assess dehydration, infection, and overall health

These services are available through local clinics, urgent care centers, and hospitals such as Corewell Health, Trinity Health Grand Rapids, Metro Health, and Mercy Health facilities.

Treatment for Gastroenteritis

1. Hydration: The Most Important Step

The main treatment for gastroenteritis is replacing lost fluids and electrolytes.

  • Sip small amounts of fluid frequently, especially if you are vomiting.
  • Use oral rehydration solutions (ORS) from local Grand Rapids pharmacies (Meijer, CVS, Walgreens, etc.). These contain the right balance of salts and sugars.
  • Avoid sugary drinks, energy drinks, and full-strength fruit juice, which can sometimes worsen diarrhea.
  • For adults, water, ORS, clear broths, and electrolyte drinks are usually helpful.
  • For children, follow your pediatrician’s advice; oral rehydration solutions are often best.

In severe cases—especially in young children, older adults, or people with chronic illnesses—hospital admission and IV (intravenous) fluids may be needed. This is available at emergency departments throughout Grand Rapids.

2. Medications

Treatment depends on the cause:

  • Antibiotics – may be prescribed if a bacterial infection is confirmed or strongly suspected. Not all bacterial gastroenteritis needs antibiotics; your provider will decide.
  • Anti-parasitic drugs – used if tests show a parasitic infection such as giardiasis or cryptosporidiosis.
  • Anti-nausea medications – sometimes prescribed to help you keep fluids down.
  • Anti-diarrheal medications – should be avoided unless specifically recommended by your doctor. They can sometimes keep the infection inside your body longer or be unsafe in certain infections.

Always follow your Grand Rapids healthcare provider’s advice before taking over-the-counter medications for vomiting or diarrhea.

3. Rest and Diet

  • Rest as much as possible.
  • Start with bland foods when you can eat again: toast, crackers, bananas, rice, applesauce.
  • Avoid greasy, spicy, or high-fiber foods until you feel better.
  • Continue regular feeding for infants and children as advised by their pediatrician; do not dilute formula unless instructed.

Preventing Gastroenteritis in Grand Rapids

Gastroenteritis is highly contagious. Good hygiene and safe food practices are especially important in a four-season climate like West Michigan, where indoor crowding in winter can increase spread.

Handwashing: Your Best Defense

Wash hands thoroughly with soap and water:

  • After using the toilet
  • After changing diapers or helping a child use the bathroom
  • After handling animals or cleaning up after pets
  • After blowing your nose, coughing, or using a tissue
  • Before preparing food or eating

Use soap and running water and scrub for at least 20 seconds. Dry with disposable paper towels rather than shared cloth towels, since germs can survive on fabric.

Note: Alcohol-based hand sanitizers, while effective against some viruses (like coronavirus), are not reliable against all causes of gastroenteritis, especially certain stomach viruses. Soap and water is best.

Stay Home When Sick

To protect your family, coworkers, and classmates:

  • Stay home while you are sick with vomiting or diarrhea.
  • Remain home for at least 48 hours after your symptoms have stopped, as you may still be contagious.
  • Children with gastroenteritis should stay home from school, daycare, and sports until at least 48 hours symptom-free.

Safe Food Handling in Your Grand Rapids Kitchen

Keep your kitchen clean and practice safe food handling:

  • Separate raw and cooked foods

    • Use different cutting boards, knives, and tongs for raw meat and ready-to-eat foods.
    • Wash utensils and surfaces thoroughly with hot, soapy water between uses.

  • Keep cold foods cold and hot foods hot

    • Cold foods: below 5°C (41°F)
    • Hot foods: above 60°C (140°F)
    • Refrigerate leftovers promptly—within 2 hours (or within 1 hour in hot weather, such as summer cookouts in West Michigan).

  • Cook foods thoroughly

    • Cook poultry and ground meats to safe internal temperatures.
    • Avoid eating raw or undercooked eggs, meat, or poultry.

  • Clean surfaces and objects regularly

    • Wipe and disinfect kitchen counters, cutting boards, and utensils.
    • Clean bathroom surfaces, especially toilet seats, flush handles, door handles, and faucets.
    • Clean baby changing tables after each use.

Preventing Spread at Home

If someone in your Grand Rapids household has gastroenteritis:

  • Disinfect frequently touched surfaces (phones, remotes, doorknobs, light switches).
  • Wash soiled clothes and bedding promptly in hot water.
  • Use gloves when cleaning up vomit or stool, and wash your hands thoroughly afterward.
  • Keep sick children away from group activities, daycare, and school until fully recovered.

Travel and Outdoor Precautions

When traveling—especially to areas with poor sanitation—or camping in Michigan:

  • Drink only bottled or properly treated water.
  • Use bottled or boiled water to brush your teeth.
  • Avoid ice in drinks if you are unsure of water quality.
  • Avoid raw or undercooked foods, food buffets, and unpeeled fruits and vegetables.
  • Do not swallow water when swimming in lakes, rivers, or pools.
