Should you go to urgent care for a stomach bug? Most stomach bugs pass on their own within one to three days, and rest plus fluids is usually enough. You should be seen when you cannot keep liquids down, show signs of dehydration, have a high fever, see blood in your stool or vomit, or when symptoms last longer than a couple of days. At Urgent Care & Family Medicine in Conway, SC, we can check your hydration, run on-site lab tests when they are needed, and help you feel better faster. Walk-ins are welcome, or you can call ahead.

What Is a Stomach Bug?
“Stomach bug” is the everyday name for gastroenteritis, which is inflammation of the stomach and intestines. Viruses such as norovirus cause most cases, especially the ones that sweep through schools, offices, and households. Bacteria from undercooked food or contaminated water can cause similar symptoms, and so can some parasites, though those are less common.
Even though people often call it the “stomach flu,” it is not influenza. The flu is a respiratory illness. A flu shot does not prevent gastroenteritis, and antibiotics do nothing against the viruses that cause most stomach bugs. If you are dealing with fever, body aches, and cough instead, read our post on when to go to urgent care for the flu.
What Are the Common Symptoms?
Symptoms usually start suddenly, often 12 to 48 hours after exposure. They can include:
- Nausea and vomiting
- Watery diarrhea
- Stomach cramps or a crampy, uneasy belly
- Low-grade fever and chills
- Headache, tiredness, and muscle aches
- Loss of appetite
For most healthy adults, the worst of it lasts about a day, and they feel close to normal within three days. Children, older adults, pregnant women, and people with chronic conditions such as diabetes or kidney disease can get dehydrated more quickly and may need care sooner.
When Should You Go to Urgent Care for a Stomach Bug?
Come see us if any of these apply:
- You cannot keep even small sips of fluid down for more than about 12 hours
- Diarrhea lasts longer than two days for an adult, or vomiting lasts longer than a day
- You have a fever of 102°F or higher
- You notice signs of dehydration (see below)
- Your stool is black or bloody, or you see blood in your vomit
- You recently traveled, ate at a restaurant linked to illness, or several people who shared a meal got sick
- You have diabetes and are struggling to manage your blood sugar while sick
- You are pregnant or have a weakened immune system
Our providers can examine you, check your vital signs, and order on-site lab work when it helps answer the question. Learn more about our on-site labwork and x-rays.
Can’t keep fluids down? Our team in Conway can help. Walk in during open hours or call before you come.
What Are the Signs of Dehydration?
Dehydration is the main risk with any stomach bug. Watch for:
- Very dark yellow urine, or not urinating for eight hours or more
- Dry mouth, dry lips, and extreme thirst
- Dizziness or lightheadedness, especially when you stand up
- A fast heartbeat
- Unusual tiredness, weakness, or confusion
- In children: no tears when crying, few wet diapers, sunken eyes, or unusual sleepiness
Mild dehydration can often be fixed at home with oral rehydration drinks. If you are moderately dehydrated and cannot keep fluids down, our clinic offers IV hydration, which delivers fluids directly into a vein. You can read more in our post on IV hydration in Conway.
When Is a Stomach Bug an Emergency?
Some symptoms point to something more serious than a routine stomach bug. Call 911 or go to the nearest emergency room if you have:
- Severe, constant abdominal pain, especially in the lower right side
- A rigid, hard belly that hurts to touch
- Large amounts of blood in vomit or stool
- Confusion, fainting, or trouble staying awake
- Signs of severe dehydration in an infant or elderly person
- Chest pain or trouble breathing

How Is a Stomach Bug Treated?
Because most cases are viral, treatment focuses on keeping you hydrated and comfortable while your body clears the infection. Depending on your symptoms, your provider may recommend:
- Fluids: small, frequent sips of water, oral rehydration solution, broth, or diluted sports drinks
- Anti-nausea medicine: a prescription can help you keep fluids down when vomiting is persistent
- IV fluids: for moderate dehydration when drinking is not working
- Testing: stool or blood tests if symptoms are severe, bloody, or lasting longer than expected
- Antibiotics: only in specific bacterial infections where they are known to help
Your provider will also tell you which over-the-counter medicines are safe for you. Anti-diarrheal products are not right for everyone, particularly if you have a fever or bloody stool, so it is worth asking first.
What Can You Do at Home?
For a mild case, these steps usually help:
- Rest your stomach for an hour or two after vomiting, then start with a teaspoon or two of fluid every few minutes
- Gradually increase how much you drink as you keep it down
- When you feel ready, try bland foods such as toast, crackers, rice, bananas, applesauce, or plain soup
- Avoid alcohol, caffeine, greasy or spicy foods, and very sugary drinks until you feel better
- Get plenty of rest
If you are caring for a child, offer small amounts of an oral rehydration solution often. Call your child’s provider or come in if your child seems very sleepy, stops making wet diapers, or will not drink.
How Do You Keep a Stomach Bug From Spreading?
Norovirus in particular spreads very easily. A few habits make a big difference:
- Wash hands with soap and water for at least 20 seconds, especially after using the bathroom and before eating. Hand sanitizer does not work as well against norovirus.
- Clean surfaces with a bleach-based cleaner, especially bathrooms and kitchen counters
- Wash soiled laundry on the hottest setting it can handle
- Do not prepare food for others while you are sick and for at least two days after symptoms stop
- Stay home from work or school until you have been symptom-free for at least 24 to 48 hours, or as your employer or school requires

Is It a Stomach Bug or Food Poisoning?
The two can feel almost identical. Food poisoning tends to start within hours of eating contaminated food, and several people who shared the same meal often get sick around the same time. A viral stomach bug more often spreads person to person over several days, moving through a household or classroom. In both cases the first priority is the same: stay hydrated and watch for warning signs. If symptoms are severe, bloody, or not improving, your provider may order a stool test to look for bacteria that need specific treatment. Telling us what you ate, where, and when can help narrow down the cause.

Frequently Asked Questions
How long does a stomach bug usually last?
Most stomach bugs last one to three days. Norovirus often improves within 24 to 72 hours. If symptoms last longer than two days for an adult, or you are getting worse instead of better, it is a good idea to be seen.
Is a stomach bug contagious?
Yes. Viral stomach bugs such as norovirus spread easily through contaminated hands, food, surfaces, and close contact. People can remain contagious for a few days after they feel better, so careful handwashing matters.
Will I get antibiotics for a stomach bug?
Usually not. Most stomach bugs are caused by viruses, and antibiotics do not treat viruses. Antibiotics are used only for specific bacterial infections when your provider finds a reason to prescribe them.
Can urgent care give IV fluids for dehydration?
Yes. Our Conway clinic offers IV hydration for patients who are moderately dehydrated and cannot keep fluids down. Your provider will decide whether IV fluids are right for you after an exam.
Do I need an appointment?
No. Walk-ins are welcome during open hours. You can also call 843-347-2121 before you come in if you have questions.
