What Causes Stomach Illnesses

Food poisoning is a common reason people seek urgent care for nausea, vomiting, and diarrhea, but it isn't the only possible cause. Several illnesses can produce similar digestive symptoms, making a professional evaluation important.

Food Poisoning

Food poisoning occurs after eating or drinking contaminated food or beverages. Symptoms often develop within hours or days and may include nausea, vomiting, diarrhea, stomach cramps, and fever.

Viral Gastroenteritis (Stomach Bug)

Often referred to as the "stomach flu," viral gastroenteritis is a contagious infection that affects the digestive system. It commonly causes vomiting, diarrhea, stomach cramps, and fatigue.

Other Possible Causes

Digestive symptoms may also be related to:

Medication side effects

Food intolerances

Bacterial or parasitic infections

Other digestive conditions

Medical conditions that require further evaluation

Since many conditions can cause similar digestive symptoms, an evaluation is often the best way to determine the underlying cause and whether additional treatment is needed.

When to Visit Urgent Care for Food Poisoning & Stomach Illnesses

Stomach illnesses often cause a combination of symptoms that can range from mild to more severe. Many cases of food poisoning and stomach illnesses improve with rest and hydration. Still, persistent or worsening symptoms should be evaluated by a medical provider to help prevent complications such as dehydration.

You should consider visiting urgent care if you have:

Vomiting that continues for several hours

Frequent diarrhea

Difficulty keeping fluids down

Persistent stomach pain or cramping

Fever along with nausea, vomiting, or diarrhea

Symptoms that are not improving after a reasonable amount of time

Concern that your symptoms may be related to food poisoning

Symptoms that make it difficult to work, attend school, or perform normal daily activities

Our providers thoroughly evaluate you to determine the most appropriate treatment based on the cause and severity of your symptoms.

Watch for Signs of Dehydration

Vomiting and diarrhea can cause your body to lose fluids more quickly than you can replace them. Young children, older adults, and people with certain medical conditions may be at greater risk of becoming dehydrated.

Signs of dehydration may include:

Dry mouth

Dark-colored urine

Weakness

Feeling lightheaded when standing

Increased thirst

Dizziness

Fatigue

Urinating less often than usual

If you're concerned that dehydration is developing, prompt medical evaluation can help determine whether additional treatment is needed.

How We Evaluate Food Poisoning & Stomach Illnesses

Whether your symptoms are caused by food poisoning, a stomach bug, or another digestive illness, our providers begin with a thorough evaluation rather than making assumptions based on symptoms alone.

During your visit, our providers may:

Review your symptoms and when they began

Discuss recent meals, travel, or possible exposures when appropriate

Review your medical history and current medications

Perform a physical examination

Depending on your symptoms and examination, additional testing may be recommended when clinically appropriate. This may include:

  • Urinalysis to help assess hydration status or evaluate for other possible causes of your symptoms
  • Bloodwork when symptoms suggest dehydration, infection, or another medical condition that requires further evaluation

Testing is recommended only when it is medically appropriate and based on your symptoms.

Treatment Depends on the Cause

Food poisoning treatment depends on the severity of your symptoms and the underlying cause. Since nausea, vomiting, and diarrhea can result from several different conditions, the most appropriate care depends on what's causing your symptoms and how severe they are.

Your personalized treatment plan may include:

  • Recommendations to help maintain hydration
  • Guidance for managing nausea, vomiting, or diarrhea
  • Dietary recommendations during recovery
  • Treatment based on your diagnosis
  • Instructions for monitoring your symptoms at home
  • Follow-up recommendations if your symptoms persist or worsen

Our goal is to help you recover safely while identifying any signs that additional medical care may be needed.
