stomach with nausea

Overview

Nausea is that sick feeling in your stomach that makes you feel like you might vomit (throw up). It’s not a disease itself but a symptom of many different things – from a mild stomach bug to something more serious.

Yes, nausea is one of the most common reasons people visit their doctor or feel unwell.

Nausea can affect anyone, at any age – from infants to older adults.

Symptoms

Common symptoms

• Feeling queasy or sick to your stomach
• An urge to vomit
• Stomach discomfort or cramping
• Dizziness or lightheadedness
• Increased saliva (spit) in your mouth

Symptoms in children

• Crankiness or fussiness
• Pale skin
• Lack of appetite
• Complaining of belly pain

Symptoms in older adults

• Loss of appetite
• Confusion or weakness (sometimes nausea is less obvious)
• Dry mouth or dehydration from not drinking enough
• Worsening of other health conditions

Causes

Main causes

• Viral or bacterial infections (like stomach flu or food poisoning)
• Motion sickness or seasickness
• Pregnancy (especially in the first trimester)
• Emotional stress or anxiety
• Certain medications (such as antibiotics or pain relievers)
• Overeating or eating spoiled food

Risk factors

• Traveling by car, boat, or airplane
• Being pregnant
• Having a sensitive stomach or a history of migraines
• Taking medications that can upset the stomach
• Having a chronic condition like acid reflux or irritable bowel syndrome

When to see a doctor

See a doctor urgently if:

• Nausea with chest pain or shortness of breath
• Nausea with severe headache or neck stiffness
• Nausea with blood in your vomit (looks like coffee grounds) or in your stool
• Nausea with confusion or loss of consciousness
• Nausea after a recent head injury

Book a routine appointment if:

• Nausea that keeps coming back or lasts longer than a week
• Nausea that makes it hard to eat or drink anything
• Nausea that wakes you from sleep
• Nausea along with unexplained weight loss

Diagnosis

Your doctor will ask about your symptoms, when they started, and what makes them better or worse. They may also check your vital signs and do a physical exam.

Tests that may be done

• Blood tests to check for infection or dehydration
• Urine test to look for signs of pregnancy or infection
• Stool sample to test for bacteria or viruses
• Imaging tests (like an ultrasound or CT scan) if the cause is unclear

What to expect at your appointment

Most people with nausea do not need any special tests. Your doctor will likely give you advice on self-care and when to follow up. If tests are needed, they are usually simple and done in the doctor’s office or a nearby lab.

Treatment

Treatment depends on the cause. For most mild nausea, simple home remedies and rest are enough. If an underlying condition is found, your doctor will treat that condition.

Self-care at home

• Sip clear fluids like water, diluted fruit juice, or clear broth frequently
• Eat small, bland meals like crackers, toast, or rice
• Avoid strong smells (like cooking food, perfume, or smoke)
• Get fresh air or sit near a fan
• Rest in a quiet room and try to relax

Medical treatments

If nausea is severe or due to a medical condition, your doctor may recommend over-the-counter remedies (always check with a pharmacist first) or prescribe medications to calm the stomach. These are not the same as drugs for vomiting. For nausea caused by motion sickness, special patches or pills may help.

When is surgery considered?

Surgery is rarely needed for nausea alone. It may be needed if nausea is caused by a blockage in the bowel or a problem with the gallbladder or appendix – but only after careful diagnosis.

Living with this condition

You can manage mild nausea at home by avoiding triggers and taking care of yourself. If you have a chronic condition that causes nausea, work with your doctor to have a plan.

Lifestyle tips

• Eat small, frequent meals instead of large ones
• Avoid spicy, greasy, or very sweet foods
• Stay hydrated throughout the day
• Get regular exercise (gentle walking can help)
• Practice relaxation techniques like deep breathing or meditation

Diet and exercise

A plain diet – like the BRAT diet (bananas, rice, applesauce, toast) – can help settle your stomach. Avoid high-fiber foods until you feel better. Gentle movement, like a short walk, may reduce nausea, but avoid vigorous exercise when you’re queasy.

Mental health and emotional wellbeing

Feeling sick can be stressful and may affect your mood. It’s normal to feel frustrated or worried. If nausea is long-term, it may lead to anxiety or depression. Talk to your doctor if you’re struggling emotionally.

Prevention

Not all nausea can be prevented, but you can reduce your risk. Avoid foods that have been left out too long, wash your hands regularly, and take motion sickness medicine before travelling if you’re prone to it.

Complications

If left untreated

• Dehydration from not drinking enough fluids
• Electrolyte imbalances (mineral levels in your blood can get out of balance)
• Weight loss or poor nutrition
• Damage to the esophagus (the tube connecting your mouth to your stomach) from repeated vomiting

Long-term outlook

Most people with nausea recover completely without any long-term problems. Even if nausea is caused by a chronic condition, it can often be managed well with the right treatment and lifestyle changes.
