pneumonia when to seek care

Overview

Pneumonia is an infection in one or both lungs. It causes the tiny air sacs inside the lungs to fill with fluid or pus, making it harder to breathe and causing cough, fever, and chest pain. It can be mild or serious, and it affects people of all ages.

Yes. Pneumonia is common worldwide. Many people get it at some point in their lives, and it is one of the most common reasons people visit the doctor or hospital.

Anyone can get pneumonia, but it is more likely to be serious in infants, young children, older adults, people with chronic health conditions, and people with weakened immune systems.

Symptoms

Common symptoms

• A cough that may bring up mucus, which can be clear, yellow, green, or sometimes bloody
• Fever, sweats, and chills
• Shortness of breath or fast breathing
• Chest pain that gets worse when you breathe deeply or cough
• Feeling very tired or weak
• Loss of appetite

Symptoms in children

• Fast breathing or grunting while breathing
• Flaring of the nostrils when breathing in
• The area between the ribs or below the ribs pulling in with each breath
• Cough and fever
• Irritability or unusual drowsiness
• Poor feeding or dehydration

Symptoms in older adults

• Confusion or changes in mental awareness
• A lower-than-normal body temperature instead of fever
• Weakness and fatigue
• Loss of balance or falls
• A cough that may not be very noticeable
• Less interest in food or fluids

Causes

Main causes

• Viruses, including the flu virus and the virus that causes COVID-19
• Bacteria, most commonly Streptococcus pneumoniae
• Fungi, which are less common and usually affect people with weakened immune systems
• In rare cases, inhaling food, liquid, or fumes into the lungs can cause 'aspiration pneumonia'

Risk factors

• Being under 5 or over 65 years old
• Smoking or exposure to secondhand smoke
• Chronic lung diseases like asthma, COPD, or cystic fibrosis
• Diabetes, heart disease, kidney disease, or liver disease
• A weakened immune system from HIV, cancer treatment, or medications that suppress immunity
• Being in a hospital or care setting, especially on a ventilator
• Having trouble swallowing or coughing (which can cause aspiration)

When to see a doctor

See a doctor urgently if:

• If you have trouble breathing, chest pain, or cough up blood, see a doctor the same day
• If you have a high fever that doesn't come down with over-the-counter medicine (as directed on the label), seek care promptly
• If you feel confused, very sleepy, or too weak to do daily tasks
• If you are older, very young, or have a chronic condition and have symptoms of pneumonia

Book a routine appointment if:

• If you have a persistent cough, fever, or feeling of being unwell for more than a few days, make a routine appointment
• If you have already been to a doctor and your symptoms get worse after a couple of days, follow up with your healthcare provider

Diagnosis

A doctor will ask about your symptoms and medical history, and listen to your lungs with a stethoscope. They may check your oxygen level with a small sensor on your finger. If pneumonia is suspected, they may order more tests.

Tests that may be done

• Chest X-ray to look for signs of infection in the lungs
• Blood tests to check for infection and see how severe it is
• A mucus sample from coughing (sputum culture) to see which germ is causing the infection
• A pulse oximetry test to measure the oxygen level in your blood

What to expect at your appointment

The doctor will explain what you have and whether it is likely viral or bacterial. They may prescribe medicine or advise home care. You may be given a follow-up appointment to check that your lungs are clearing up.

Treatment

Treatment depends on the cause, how severe the pneumonia is, and your overall health. Viral pneumonia usually needs rest and supportive care. Bacterial pneumonia is typically treated with antibiotics prescribed by a doctor. Some people with severe pneumonia need care in the hospital, including oxygen or help breathing.

Self-care at home

• Rest as much as possible and go slowly as you recover
• Drink plenty of fluids to stay hydrated and help thin mucus
• Use a cool-mist humidifier or take a steamy shower to ease cough
• Avoid smoking, secondhand smoke, and other lung irritants
• Take over-the-counter fever reducers or pain relievers only as directed on the label and never give aspirin to children under 16

Medical treatments

For bacterial pneumonia, doctors prescribe antibiotics. For viral pneumonia, antibiotics are not effective; the focus is on rest, fluids, and managing symptoms. In severe cases, you may need oxygen therapy, IV fluids, or breathing support in the hospital. Always follow the treatment plan given by your healthcare provider, and finish all prescribed medicine exactly as directed.

When is surgery considered?

Surgery is rarely needed for pneumonia. In rare cases, a pocket of pus around the lung (empyema) or a lung abscess may require a drainage procedure or surgery. Your doctor will explain if this is necessary for your situation.

Living with this condition

Recovery from pneumonia can take time. Even after the infection clears, you may feel tired for weeks. Go back to your normal routine gradually. Avoid heavy physical activity until you feel your energy returning. Keep all follow-up appointments so your doctor can make sure you are healing well.

Lifestyle tips

• Get plenty of sleep and rest
• Drink fluids such as water, warm tea, and soups to stay hydrated
• If you smoke, consider talking to a healthcare professional about help to quit
• Practice deep breathing exercises when you feel up to it to help clear your lungs
• Wash your hands often to avoid catching new respiratory infections

Diet and exercise

Eat nutritious meals with fruits, vegetables, whole grains, and protein to give your body strength for healing. It is normal to have less appetite – eat small amounts often. Once you feel better, gentle movement like short walks can help circulation, but talk to your doctor before resuming intense exercise.

Mental health and emotional wellbeing

Being ill with pneumonia can feel scary or exhausting. You may feel anxious, low, or frustrated, especially if recovery is slow. These feelings are normal. Talk to your doctor if you feel very anxious or depressed, and remember that crisis support is available if you need help right away.

Prevention

Many cases of pneumonia can be prevented. Good hygiene, like handwashing and covering coughs, helps stop the spread of germs. Not smoking and limiting exposure to smoke helps keep your lungs strong. Staying healthy overall with a balanced diet, exercise, and enough sleep supports your immune system.

Vaccines

Vaccines are available for some pneumonia-causing bacteria and viruses, including the pneumococcal vaccine, the flu vaccine, the COVID-19 vaccine, and whooping cough vaccine. Talk to your doctor or pharmacist about which vaccines are recommended for you or your child.

Screening programmes

There is no routine screening test for pneumonia in healthy people. You are checked for pneumonia if you have symptoms. Let your doctor know if you are at higher risk because of age or health conditions.

Complications

If left untreated

• Severe breathing failure, sometimes needing a breathing tube and machine
• Sepsis, a dangerous body-wide reaction to infection
• A pocket of pus around the lung (empyema)
• Lung abscess, where a pocket of pus forms inside the lung
• Spread of infection to other parts of the body

Long-term outlook

Most people with pneumonia recover fully with proper care, though it may take weeks or even a month or more to feel completely normal. The outlook is better when you seek medical care early and follow your doctor's advice. With the right treatment and support, even severe pneumonia can be overcome.
