Viral gastroenteritis, also known as the "stomach flu," can hit fast and leave you feeling drained. At Gastrodoxs in Houston, we know how stressful it can be to deal with sudden stomach cramps and frequent trips to the bathroom. In this guide, we’ll explain what viral gastroenteritis is, how it spreads, the symptoms to watch for, and simple ways to prevent it. Dr. Bharat Pothuri shares expert tips to help you recover quickly.
Viral gastroenteritis is an infection of the stomach and intestines caused by a virus. It’s different from the flu that affects your lungs in winter. This “stomach flu” can affect anyone, from kids to adults, and spreads quickly in crowded places like schools, offices, or homes in Houston.
Quote from Dr. Bharat Pothuri:
“Viral gastroenteritis is common, but most people recover at home with rest and simple fluids. Knowing the basics helps you feel better faster.”
Understanding how the virus spreads helps you stop it. It spreads in the following ways:
In Houston, most cases start when someone touches a contaminated surface and then touches their mouth. Practicing good hand hygiene helps prevent the spread.
Common symptoms appear 1–2 days after exposure. These include:
If a child in your home shows these signs, watch closely. Dehydration can happen quickly.
Here’s how to tell viral gastroenteritis from bacterial gastroenteritis:
| Feature | Viral Gastroenteritis | Bacterial Gastroenteritis |
| Common Causes | Norovirus, rotavirus | E. coli, Salmonella |
| Onset of Symptoms | 1–2 days after exposure | 6–24 hours after exposure |
| Type of Diarrhea | Watery, non-bloody | May be bloody or mucousy |
| Fever | Mild to moderate | High fever possible |
| Duration | 1–3 days | 3–7 days or more |
| Treatment | Rest, fluids, electrolytes | Sometimes antibiotics |
Quote from Dr. Bharat Pothuri:
“Most viral cases resolve on their own. Bacterial forms may need antibiotics. Accurate diagnosis helps guide the right treatment.”
When dealing with viral gastroenteritis, focus on comfort and hydration:
Quote from Dr. Bharat Pothuri:
“Home care focuses on gentle foods and fluids. Call your Houston care team if symptoms worsen or last beyond a few days.”
Most people feel better after 48–72 hours. If you’re still unwell after 7 days, check with your Gastrodoxs provider or your local Houston clinic.
Yes, dehydration is a common risk. Diarrhea and vomiting can quickly deplete your body of water and important electrolytes like sodium and potassium.
“Mild dehydration can be treated at home,” says Dr. Pothuri. “But if you or a loved one shows severe signs like confusion, fainting, or no urination, seek immediate help.”
Stopping the spread of the virus is key. Follow these tips:
“Proper hygiene in Houston’s busy community centers makes a huge difference,” Dr. Pothuri reminds us.
Most people recover at home, but see a doctor if you experience:
Gastrodoxs offers both telehealth and in-person visits in Houston. If you need IV fluids or intensive treatment, visit your local urgent care or ER.

It’s a stomach infection caused by viruses like norovirus. It spreads through person-to-person contact, contaminated food or water, and touching infected surfaces.
Common symptoms include watery diarrhea, vomiting, stomach cramps, low-grade fever, headache, and mild dehydration.
Stay hydrated, rest well, eat bland foods (BRAT diet), and monitor hydration. Only use medications if a doctor approves.
Most people recover in 1-3 days, with full recovery in about a week. If it lasts longer, see a doctor.
Wash hands often, clean and disinfect surfaces, cook food safely, and stay home when sick.
Viral gastroenteritis is watery and short-lived, while bacterial can cause bloody stool, high fever, and last longer. Bacterial cases sometimes need antibiotics.
Yes. Diarrhea and vomiting lead to fluid loss. Watch for dark urine, dizziness, and dry mouth.
Not always. Other conditions cause vomiting too. See a doctor if vomiting is severe or persistent.
Wait at least 48 hours after diarrhea and vomiting stop to reduce the risk of spreading the virus.
