Fatigue in older adults

Overview

Fatigue is not just feeling tired. It's an overwhelming, persistent feeling of exhaustion that doesn't go away with rest. In older adults, it can interfere with daily activities like walking, cooking, or even getting out of bed.

Yes, feeling very tired is a common complaint among older adults. Studies suggest that 1 in 3 adults over 65 experiences fatigue regularly. But it is not a normal part of aging, and it is often treatable.

Fatigue can affect any older adult, but it is more common in those with long-term health conditions such as heart disease, diabetes, or arthritis. It also affects people who take multiple medications, have poor sleep, or feel lonely.

Causes

Main causes

• Anemia (low iron or vitamin B12 levels)

When to see a doctor

See a doctor urgently if:

• Fatigue that comes on suddenly or is severe
• Fatigue with chest pain, breathlessness, or fainting

Book a routine appointment if:

• Fatigue that lasts more than two weeks
• You feel too tired to do your usual activities
• You have other symptoms like weight loss, pain, or mood changes

Diagnosis

Your doctor will start by asking you about your fatigue, your daily routine, your sleep, and any other symptoms. They will also review your medical history and any medications you take.

Tests that may be done

• Blood tests to check for anemia, thyroid problems, vitamin deficiencies, and diabetes
• A sleep study if sleep apnea is suspected
• Heart tests such as an electrocardiogram (ECG) if heart disease is a possibility
• A depression screening questionnaire

What to expect at your appointment

The doctor may ask you to keep a fatigue diary for a week or two – noting when you feel tired and what helps. This can give valuable clues. Most tests are simple and can be done during a routine visit to your GP or a geriatrician.

Treatment

Treatment for fatigue depends on the cause. Often, addressing an underlying health condition, adjusting medications, or improving sleep and nutrition can make a big difference. Your doctor will work with you to create a plan that fits your life.

Self-care at home

• Aim for 7–8 hours of sleep each night. Keep a regular bedtime routine.
• Stay physically active with gentle activities like walking, chair exercises, or tai chi. Start slowly and build up.
• Eat a balanced diet with plenty of fruits, vegetables, lean protein, and whole grains. Stay hydrated.
• Take breaks during the day, but avoid long naps (keep them to 20 minutes or less).
• Reduce stress through relaxation techniques like deep breathing or listening to music.

Medical treatments

If an underlying condition is found, your doctor may recommend treatment such as iron or vitamin supplements (only if a deficiency is confirmed), medication for thyroid problems, or adjustments to your medicines. For sleep problems, you may be referred to a sleep specialist. For depression, talking therapies like counselling can help. Your doctor will explain the options and their benefits and risks.

When is surgery considered?

Surgery is almost never needed for fatigue itself. In rare cases, if fatigue is caused by a condition like severe anaemia from blood loss or a growth in the body that needs to be removed, surgery may be part of the treatment plan.

Living with this condition

Living with fatigue can be frustrating, but there are ways to manage it. Plan your day around your energy peaks. Do the most important tasks when you feel best. Ask family or friends for help with heavy chores like shopping or cleaning. Use assistive tools like a walking stick or a perching stool in the kitchen to conserve energy.

Lifestyle tips

• Set realistic goals each day. It is okay to rest when you need to.
• Stay connected with others – join a club, call a friend, or attend a local community group.
• Keep a routine: eat, sleep, and do activities at about the same time each day.
• Avoid alcohol and smoking, as they can worsen fatigue.

Diet and exercise

Eat small, frequent meals to maintain energy. Include foods rich in iron (such as lean red meat or spinach), Vitamin B12 (eggs, dairy), and water. Gentle exercise like walking for 10–15 minutes a few times a day can actually boost energy over time. Always talk to your doctor before starting a new exercise program.

Mental health and emotional wellbeing

Ongoing fatigue can make you feel sad, anxious, or hopeless. It is common to feel frustrated or alone. Remember that fatigue is a physical symptom, not a sign of laziness. Talking to a counsellor or joining a support group can help. If you have thoughts of harming yourself, call your local emergency number or a crisis helpline immediately.

Prevention

While not all fatigue can be prevented, you can reduce your risk by staying physically active, eating well, managing ongoing health conditions, and getting enough sleep. Regular check-ups can catch problems early.

Complications

If left untreated

• Higher risk of falls and fractures
• Difficulty caring for yourself (e.g., bathing, cooking)
• Social isolation and loneliness
• Worsening of other health conditions
• Increased risk of depression

Long-term outlook

Most causes of fatigue in older adults can be treated or improved. With the right help, many people regain their energy and return to activities they enjoy. It may take time, but small steps every day can lead to big improvements in how you feel.
