Nausea and vomiting are common symptoms that affect both adults and children. They can be caused by a wide range of conditions, from mild stomach viruses and food-related issues to medication side effects or more serious underlying illnesses.
In many cases, these symptoms resolve on their own within a short period. However, persistent vomiting can lead to dehydration, especially in young children, older adults, and individuals with chronic health conditions.
Severe dehydration, inability to keep fluids down, vomiting blood, severe abdominal pain, confusion, or signs of weakness should be treated as medical emergencies and require immediate evaluation at the nearest emergency room.
For non-emergency symptoms, UrgiClinic can help assess and manage gastrointestinal concerns through What We Treat.
What Is Nausea?
Nausea is the sensation of feeling like you may vomit. It is not a condition itself but a symptom of an underlying issue affecting the digestive system, nervous system, or other parts of the body. Nausea can be triggered by infections, motion sickness, medications, or digestive disorders.
What Causes Nausea and Vomiting?
Nausea and vomiting can have many different causes depending on age, health status, and exposure history.
Viral or Bacterial Infections
Stomach viruses (gastroenteritis) are one of the most common causes in both adults and children.
Food Poisoning
Contaminated or improperly handled food can trigger sudden vomiting and nausea.
Motion Sickness
Movement during travel by car, boat, or airplane can affect the inner ear and cause symptoms.
Medications
Certain medications may irritate the stomach or trigger nausea as a side effect.
Stress and Anxiety
Emotional stress can affect the digestive system and lead to stomach upset.
Pregnancy
Morning sickness is a common cause of nausea in early pregnancy.
Symptoms of Nausea and Vomiting
Common symptoms include:
- Queasiness or stomach discomfort
- Vomiting or dry heaving
- Loss of appetite
- Weakness or fatigue
- Dizziness or lightheadedness
- Abdominal cramping
In children, symptoms may also include irritability, crying, or refusal to eat or drink.
When Nausea and Vomiting Become Serious
While most cases are mild, some symptoms indicate the need for medical evaluation.
Seek care if you experience:
- Vomiting lasting more than 24–48 hours
- Inability to keep fluids down
- Signs of dehydration (dry mouth, reduced urination, lethargy)
- Blood in vomit or black-colored vomit
- Severe abdominal pain
- High fever
- Confusion or weakness
The Centers for Disease Control and Prevention (CDC) notes that foodborne illnesses are a major cause of vomiting and can become serious if dehydration develops.
Nausea and Vomiting in Children
Children are more vulnerable to dehydration due to smaller fluid reserves.
Warning signs in children include:
- Fewer wet diapers or urination
- Sunken eyes
- Dry lips or mouth
- Unusual sleepiness or irritability
- Refusal to drink fluids
Parents should monitor children closely and seek care early if symptoms persist.
How Nausea and Vomiting Are Diagnosed
Diagnosis typically involves a physical evaluation and symptom review. A healthcare provider may ask about:
- Duration of symptoms
- Recent food intake
- Exposure to sick individuals
- Medication use
- Travel history
In some cases, additional testing may be needed to identify infection or underlying conditions.
At UrgiClinic, providers can evaluate gastrointestinal symptoms through our Medical Assistance services.
Treatment for Nausea and Vomiting
Treatment depends on the underlying cause and severity of symptoms.
Hydration
Replacing lost fluids is the most important step. Oral rehydration solutions may be recommended.
Dietary Changes
Small, bland meals are often easier to tolerate once vomiting improves.
Medications
Anti-nausea medications may be used when appropriate.
Rest
Allowing the body time to recover is essential, especially in viral infections.
