Tuberculosis treatment journey in older adults

Overview

Tuberculosis, or TB, is an infection caused by bacteria that usually affects the lungs. With treatment, most people recover completely.

TB is less common in the UK than in some other parts of the world, but it still affects thousands of people each year, including older adults.

TB can affect anyone, but older adults are at higher risk because the immune system weakens with age. People living in crowded conditions or with certain long-term health problems are also more at risk.

Symptoms

Common symptoms

• A cough that lasts more than three weeks
• Coughing up phlegm or blood
• Chest pain or pain when breathing or coughing
• Unexplained weight loss
• Feeling tired or weak
• Fever or night sweats

Symptoms in children

• Cough, fever, and weight loss
• Swollen lymph nodes in the neck
• Slow growth or not gaining weight

Symptoms in older adults

• A cough that may be mild or not noticeable
• Feeling generally unwell, confused, or weak
• Loss of appetite and weight loss
• Night sweats and fever may be less obvious

Causes

Main causes

• TB is caused by bacteria called Mycobacterium tuberculosis. It spreads through the air when an infected person coughs or sneezes.

Risk factors

• Being 65 years or older
• A weakened immune system due to age, illness, or medications
• Living in close contact with someone who has TB
• Living in a nursing home or other group setting
• Poor nutrition or other health problems like diabetes

When to see a doctor

See a doctor urgently if:

• If you have a cough that has lasted more than three weeks
• If you have unexplained weight loss, night sweats, or fever
• If you have been in close contact with someone who has TB

Book a routine appointment if:

• If you are at higher risk for TB, such as living in a care home or having a weakened immune system, talk to your doctor about screening.

Diagnosis

Your doctor will ask about your symptoms and health history. They may order a chest X‑ray, a sputum test (mucus from your lungs), or a blood test.

Tests that may be done

• Chest X‑ray to look for changes in the lungs
• Sputum test to check for TB bacteria in your phlegm
• Blood test (such as IGRA) to see if you have been exposed to TB

What to expect at your appointment

If TB is suspected, you may need to provide several sputum samples. Diagnosis may take a few days. If you are diagnosed, you will start treatment as soon as possible, and a specialist nurse will help you through the process.

Treatment

Treatment for TB uses a combination of antibiotics taken for several months. It is very effective, and most people recover fully. Older adults may need special monitoring because of other health conditions or medications they take.

Self-care at home

• Take all your medications exactly as prescribed, even if you start to feel better.
• Get plenty of rest and eat a balanced diet to help your body fight the infection.
• Avoid alcohol and smoking, as these can interfere with treatment.

Medical treatments

Treatment involves taking a combination of antibiotics every day for at least 6 months. For older adults, the doctor may adjust the dose or add a different medication if needed. Many people are also offered directly observed therapy (DOT), where a nurse watches you take your medications to ensure you get the full course. Regular blood tests and check-ups are needed to monitor progress and side effects.

When is surgery considered?

Surgery is rarely needed for TB. It may be considered in very rare cases where medication does not work or there is a complication, such as a lung abscess.

Living with this condition

Your daily routine will include taking medications at the same time each day. You may need to avoid close contact with others for the first few weeks of treatment until you are no longer infectious. Rest when you feel tired, and gradually return to normal activities as you recover.

Lifestyle tips

• Cover your mouth and nose with a tissue when you cough or sneeze.
• Wash your hands often, especially after coughing or touching your face.
• Keep windows open to let in fresh air if you are at home.

Diet and exercise

Eat a variety of nutritious foods, including proteins, fruits, and vegetables, to support your immune system. Light exercise like walking can help you regain strength, but listen to your body and avoid overexertion.

Mental health and emotional wellbeing

Having TB can feel isolating and stressful. You might feel anxious or low. It is important to talk about your feelings with your healthcare team, family, or a counsellor. Many people find support groups helpful.

Prevention

TB can be prevented in many cases. Good ventilation, covering coughs and sneezes, and treating people with active TB quickly all help stop the spread. For those at high risk, a blood test can find latent TB (inactive infection) and treatment can prevent it from becoming active.

Vaccines

The BCG vaccine is given to some babies and children in high-risk areas, but it is not generally recommended for older adults. Your doctor can advise if it is right for you.

Screening programmes

Screening for TB is offered to people at higher risk, such as those who have been in close contact with someone with TB or those from parts of the world where TB is common. Talk to your doctor if you think you need a test.

Complications

If left untreated

• TB can spread to other parts of the body, like the spine, brain, or kidneys.
• It can cause permanent lung damage and make it hard to breathe.
• Without treatment, TB can be fatal.

Long-term outlook

With proper treatment, more than 95 out of 100 people with TB are cured. Older adults may take a little longer to recover, but the outlook is very good. It is important to complete the full course of treatment to prevent the infection from coming back or becoming drug-resistant.
