Nausea in older adults

Overview

Nausea is the feeling you need to vomit but may not actually vomit. It is a common problem in older adults and can be caused by many things, including medications, infections, or other medical conditions.

Yes, nausea is a common symptom in older adults. Many people over 65 experience it at some point, especially if they take multiple medicines or have chronic conditions.

Nausea can affect anyone, but older adults are more at risk due to age-related changes in digestion, side effects from medicines, and higher rates of infections or long-term illnesses.

Symptoms

Common symptoms

• Feeling sick to your stomach
• Queasiness
• Loss of appetite
• A sensation of needing to vomit

Symptoms in children

• Children may express nausea differently, such as crying, irritability, or refusing to eat.
• They might complain of stomach pain or appear pale.

Symptoms in older adults

• May feel unsettled rather than clearly nauseated
• May have fewer or different symptoms, like confusion or dizziness
• Often accompanied by loss of appetite or weight loss

Causes

Main causes

• Side effects from medications (such as antibiotics, painkillers, or heart medicines)
• Infections like gastroenteritis (stomach flu)
• Digestive problems like acid reflux, gastritis, or constipation
• Inner ear problems (vestibular disorders) affecting balance
• Food poisoning or intolerance to certain foods
• Migraine or headaches
• Problems with the liver, kidneys, or pancreas
• Anxiety or emotional stress

Risk factors

• Taking multiple medications (polypharmacy)
• Being over 65
• Having chronic conditions like diabetes, heart disease, or Parkinson’s
• Recent surgery or hospitalization
• Poor dental health or difficulty swallowing

When to see a doctor

See a doctor urgently if:

• You have nausea along with chest pain, shortness of breath, or confusion – call emergency services immediately.
• You cannot keep any fluids down for 24 hours.
• You have signs of dehydration (dark urine, dry mouth, dizziness).
• You see blood in your vomit or stool.

Book a routine appointment if:

• You have nausea that lasts more than a few days.
• You have other symptoms like unexplained weight loss, pain, or fever.
• You are concerned about a side effect of a medicine.
• You have a long-term health condition that might be causing nausea.

Diagnosis

Your doctor will ask about your symptoms, medical history, and medications. They may also ask about your eating habits, stress levels, and any recent illnesses.

Tests that may be done

• Blood tests to check for infection, kidney or liver problems
• Urine test to look for infection or dehydration
• Stomach tests like endoscopy (a thin tube with a camera)
• Imaging scans like ultrasound or CT if needed
• Balance tests if inner ear problems are suspected

What to expect at your appointment

The doctor will work with you to find the cause. They may adjust medications or recommend simple changes. It may take a few visits to identify the exact issue, but most causes can be managed.

Treatment

Treatment depends on the cause. Often, nausea gets better with simple home remedies or adjusting current medications. Your doctor may suggest anti-nausea medicines (no specific brand names) if needed.

Self-care at home

• Drink small amounts of clear fluids often, like water or clear broth.
• Eat small, bland meals – toast, crackers, bananas, rice.
• Avoid fatty, spicy, or very sweet foods until you feel better.
• Rest and avoid strong smells.
• Ginger tea or peppermint may help soothe the stomach.
• Keep a glass of water by your bed and sip it during the night.

Medical treatments

If self-care is not enough, your doctor might prescribe medication to reduce nausea. These are usually taken as a tablet, liquid, or dissolving wafer. The exact type depends on the cause. Never use over-the-counter remedies without checking with a doctor or pharmacist, especially if you take other medicines.

When is surgery considered?

Surgery is rarely needed for nausea alone. It might be considered if the cause is a blockage in the digestive system or another condition that requires surgery.

Living with this condition

With the right approach, most people can manage nausea at home. Keep a food diary to identify triggers. Stay hydrated and eat small meals. Talk to your doctor or pharmacist about any medicines that might be causing symptoms.

Lifestyle tips

• Eat small, frequent meals instead of large ones.
• Avoid lying down right after eating.
• Drink fluids between meals, not during meals.
• Keep your home well-ventilated and avoid cooking smells if they bother you.
• Use relaxation techniques like deep breathing to reduce stress-related nausea.

Diet and exercise

Stick to a plain diet when nausea is bad. Gentle exercise like walking or stretching can help keep your digestion moving. But rest when you feel unwell. Stay active within your limits.

Mental health and emotional wellbeing

Chronic nausea can be distressing and may cause anxiety or depression. It can affect your appetite and social life. Talk to your doctor if you feel overwhelmed. They can recommend support or counseling.

Prevention

Not all nausea can be prevented, but you can reduce the risk. Eat well, drink enough fluids, and take medications as prescribed. Avoid known triggers like strong smells or fatty foods. Keep a healthy weight and manage chronic conditions.

Vaccines

Getting recommended vaccines, such as the annual flu vaccine, can help prevent infections that cause nausea.

Screening programmes

There are no routine screening tests for nausea. However, if you have a known condition like diabetes or heart disease, regular check-ups can help prevent problems that cause nausea.

Complications

If left untreated

• Dehydration and electrolyte imbalances
• Malnutrition and weight loss
• Falls due to dizziness or weakness
• Hospitalization, especially if vomiting is severe
• Worsening of underlying conditions

Long-term outlook

For most people, nausea gets better with simple treatments or by addressing the cause. Even if it takes time, there is usually a way to manage it effectively. Your healthcare team can help you find the right approach so you can feel well and stay active.
