Nausea what it can mean

Overview

Nausea is an unpleasant feeling in your stomach that makes you feel like you might vomit (throw up). It is not a disease itself, but a symptom of something else going on in your body.

Yes, nausea is extremely common. Nearly everyone will have nausea at some time in their life, often from a viral infection, food poisoning, or motion sickness.

Nausea can affect people of any age, from infants to older adults. However, some groups, such as pregnant women, people with certain medical conditions, or those taking certain medications, may experience it more often.

Symptoms

Common symptoms

• Feeling sick or queasy in the stomach
• A sensation that you might vomit
• Stomach discomfort or cramping
• Loss of appetite
• Feeling weak or sweaty

Symptoms in children

• Children may complain of a 'tummy ache' or feeling sick
• They might refuse to eat or drink
• Crying or fussiness without an obvious cause
• Pale skin or looking unwell

Symptoms in older adults

• Nausea may be less obvious and might be described as 'feeling off' or 'dizzy'
• Older adults are at higher risk for dehydration from vomiting
• They may have a loss of appetite that lasts longer
• Nausea can be a sign of a medication side effect or a more serious illness

Causes

Main causes

• Viral or bacterial infections (such as stomach flu or food poisoning)
• Motion sickness (from travel in a car, boat, or plane)
• Pregnancy (especially in the first trimester – called morning sickness)
• Side effects of medications (like antibiotics or pain relievers)
• Overeating, indigestion, or eating spoiled food
• Migraine headaches or inner ear problems (like vertigo)
• Stress, anxiety, or strong emotions
• More serious conditions such as appendicitis, pancreatitis, or gallbladder problems

Risk factors

• Travelling or being in moving vehicles
• Pregnancy
• Taking certain medications (ask your doctor or pharmacist)
• Having a history of migraines or motion sickness
• Eating undercooked or spoiled food
• Being exposed to others with stomach bugs
• Having certain medical conditions like diabetes or kidney disease

When to see a doctor

See a doctor urgently if:

• Go to an emergency room or call your local emergency number if you have chest pain, severe headache, vomit blood, or signs of stroke.
• Seek urgent care if you have severe stomach pain, can't keep fluids down for over 24 hours, or show signs of dehydration.

Book a routine appointment if:

• Make an appointment with your doctor if nausea lasts more than a few days without a clear cause.
• See a doctor if you have unexplained weight loss, frequent nausea after eating, or if you think a medication is causing it.
• Also see a doctor if nausea is affecting your daily life or if you are pregnant and worried about morning sickness.

Diagnosis

Your doctor will ask you about your symptoms, how long you've had nausea, what makes it better or worse, and any other health issues. They may also ask about your diet, travel, and medications.

Tests that may be done

• Physical examination: your doctor will check your stomach, listen to your bowel sounds, and look for signs of dehydration.
• Urine test: to check for infection or dehydration.
• Blood tests: may be done to look for signs of infection, liver or kidney problems.
• Imaging tests (like an ultrasound or CT scan) only if a specific cause is suspected, such as a blockage or gallstones.

What to expect at your appointment

Your doctor will work with you to find the cause of your nausea. Most cases are diagnosed based on your history and symptoms. Tests are only done if needed. Your doctor may suggest trying simple treatments first and checking back if symptoms don't improve.

Treatment

Treatment for nausea focuses on the underlying cause. Often, simple home care is enough. If nausea is due to a condition like a stomach bug or pregnancy, it usually gets better on its own. For severe cases, medical treatment can help control symptoms and prevent dehydration.

Self-care at home

• Sip clear fluids like water, clear broth, or an oral rehydration solution (ask your pharmacist) in small amounts frequently.
• Eat bland foods like crackers, toast, rice, or bananas once you can keep fluids down.
• Rest and avoid strong smells or spicy foods.
• Try ginger tea or ginger sweets – some people find these help.
• Use acupressure bands (sold at pharmacies) for motion sickness or pregnancy nausea.

Medical treatments

If self-care isn't enough, your doctor may recommend anti-nausea medications (antiemetics) that can be prescribed or bought over the counter. These help reduce the feeling of sickness. In severe cases, you may need fluids through a drip (intravenous) if you are dehydrated. Your doctor will choose the best option for your situation based on the cause of your nausea.

Living with this condition

If you have ongoing nausea, it can be frustrating. Keep a diary of when it happens and what seems to trigger it. Talk to your doctor about managing any underlying conditions. Small, frequent meals are often better than large ones.

Lifestyle tips

• Avoid strong odors, greasy or spicy foods, and excessive heat.
• Get fresh air when you can – a short walk may help.
• Manage stress with relaxation techniques like deep breathing or meditation.
• If motion sickness is a trigger, plan ahead (sit in the front of the car, look at the horizon).

Diet and exercise

Eat small, bland meals throughout the day. Foods like dry toast, plain crackers, boiled potatoes, and bananas are gentle on the stomach. Avoid heavy, fatty, or very sweet foods. Drink fluids between meals rather than with them. Gentle exercise like walking may help, but avoid intense activity if you feel unwell.

Mental health and emotional wellbeing

Constant nausea can make you feel anxious, irritable, or stressed. It may interfere with your daily activities and social life. It's important to talk to your doctor if it's affecting your mood. Remember that nausea is usually treatable, and you are not alone in dealing with it.

Prevention

Not all nausea can be prevented, but you can reduce your risk. Wash your hands often to prevent infections. Handle and cook food safely to avoid food poisoning. If motion sickness is a problem, try to sit in a position that minimizes movement. Avoid overeating and foods that tend to upset your stomach.

Complications

If left untreated

• Dehydration (not having enough water in your body) – this is the most common complication, especially in children and older adults.
• Electrolyte imbalances (minerals in your body get out of balance), which can cause weakness or confusion.
• Weight loss or malnutrition if nausea lasts a long time.

Long-term outlook

For most people, nausea goes away on its own or with simple home care. Even when it's caused by a more serious condition, treatment is usually effective. With proper care, you can feel better. Always talk to your doctor if you are worried.
