Is it a chest infection? Just a cough? Or is it pneumonia? Let's talk!

Have you ever had a fever with a feeling of tightness in your chest and difficulty breathing? Most of the time, we think of these as a common cold or flu, but sometimes they can be something a little more serious. That's what pneumonia is. Today, let's talk about this disease called pneumonia in detail and simply, okay?

What exactly is pneumonia?

Simply put, pneumonia is an infection of your lungs. To be precise, it is when the tiny air sacs inside your lungs called alveoli become inflamed and fill with fluid or pus. Think of your lungs as little clusters of grapes that are located behind the bronchioles that branch out like the branches of a tree. These air sacs are where the oxygen we breathe in is absorbed into the blood. So, what happens when these become infected? You can't absorb oxygen properly, you have difficulty breathing, you have chest pain, and you cough up mucus. Do you understand? This can happen in just one lung, or it can happen in both lungs.

What are the causes of pneumonia?

Now let's see what are the main causes of this disease called pneumonia. Most of the time, it is caused by tiny organisms that are invisible to our eyes.

• Bacteria: Pneumonia can occur when certain types of bacteria enter the lungs. Streptococcus pneumoniae is a common cause of pneumonia. This type of bacteria usually doesn't cause any harm in our throats and noses, but it can become a problem if it gets into the lungs when our immune system is weakened.
• Viruses: Viruses that cause illnesses like colds and flu that we all get can sometimes progress to pneumonia. This is especially common in young children and the elderly. Examples of viruses include `(Influenza virus)` (we call it the 'flu' virus), `(Respiratory Syncytial Virus - RSV)`. We have seen that the Covid-19 (`COVID-19`) virus can also cause severe pneumonia.
• Fungi: This is a little less common, but people with weakened immune systems, or those with other serious illnesses (e.g., HIV/AIDS), can also develop pneumonia due to fungal infections.
• Aspiration of food or liquids into the airways (Aspiration Pneumonia): Sometimes, especially in people who are unconscious (e.g., someone who has had a stroke) or have difficulty swallowing, food or drink, or stomach contents (acidic fluids) can enter the lungs, causing pneumonia. This is called aspiration pneumonia.

Look, there are different causes, right? That's why sometimes a doctor needs to find out exactly what type of germ is causing it before treating it.

Are there types of pneumonia?

Yes, there are some classifications of pneumonia based on how it develops and where it occurs. You don't need to study these like you're going to a big exam, but it's good to know a little bit.

• Community-Acquired Pneumonia (CAP): This is the type of pneumonia we commonly see, contracted outside of hospitals, in everyday environments.
• Hospital-Acquired Pneumonia (HAP): Pneumonia that develops while someone is in the hospital for another illness (usually within 48 hours of being admitted to the hospital). This can be quite serious, as germs found in hospitals can sometimes be resistant to medications.
• Walking Pneumonia: This is a milder, less severe form of pneumonia. Some people don't even know they have it, it just feels like a common cold. They can go about their daily lives, which is why it's called "walking" pneumonia. But it can also be serious if not treated properly.

Even though there are types like this, the most important thing is to seek medical advice as soon as symptoms appear.

How do you know if you have pneumonia? - Symptoms

Okay, now let's look at what symptoms you might get when you get pneumonia. These don't come on the same way for everyone. Some people may start slowly, while others may have a sudden onset.

• Cough: This is the main symptom. The cough may sometimes produce yellow, green, brown, or bloody phlegm. Sometimes it can start as a dry cough.
• Fever: You may develop a fever, which can be as high as 38 degrees Celsius (100.4 degrees Fahrenheit) or higher.
• Difficulty breathing: Difficulty breathing when you are slightly tired, or feeling suffocated or short of breath even when you are just standing still.
• Chest pain: You may feel a sharp, stabbing pain on one side or in the middle of your chest when you breathe or cough. This pain may worsen when you take a deep breath.
• Fatigue: Feeling tired and unable to do anything.
• Nausea, vomiting, or diarrhea: Some people may also experience these symptoms, especially young children.
• Confusion or altered consciousness: This is a symptom that is especially common among older people (over 65 years of age). They may experience some confusion, such as losing their sense of place and time.
• Sweating and feeling cold.
• Loss of appetite.
• Headache (tension) and muscle pain.

Important: In addition to fever and cough, a baby with pneumonia may also show symptoms such as chest indrawing, rapid breathing, refusal to breastfeed, drowsiness, vomiting, and abdominal distention. Therefore, if you see any of these symptoms in a baby , you should see a doctor immediately.

If you have one or more of these symptoms, it's best to see a doctor rather than dismissing it as just a cold.

Who is at higher risk of developing pneumonia?

Although anyone can develop pneumonia, some people are more likely to develop it, that is, they are at higher risk .

• Babies under 2 years old: Because their immune systems are not yet fully developed.
• People over 65 years of age: Because the immune system weakens with age and other chronic diseases may occur.
• Smokers: Smoking damages the defense mechanisms of the lungs, making them more susceptible to germs.
• People with other lung diseases: For example, people with diseases such as asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis.
• People with a weakened immune system: People with HIV/AIDS, people taking cancer medications (e.g., chemotherapy, radiotherapy), organ transplant recipients, and people taking long-term medications that suppress the immune system, such as steroids, have a reduced ability to fight off diseases.
• People with chronic diseases such as diabetes mellitus, heart disease, and kidney disease.
• People who have recently undergone major surgery or are receiving hospital treatment, especially those who have been connected to a ventilator.
• People with difficulty swallowing (dysphagia), e.g. due to stroke, Parkinson's disease.

If you fall into this category, it's a good idea to be a little more aware of the symptoms of pneumonia, and also think about ways to prevent pneumonia.

How does a doctor diagnose pneumonia?

When you go to a doctor, he or she will run several tests to find out if you have pneumonia.

• You will be asked about your medical history: What are your symptoms, how long have you had them, do you have any other illnesses, do you smoke, have you traveled recently, and is anyone else in your home sick?
• Physical Examination: The doctor will listen to your chest with a stethoscope, looking for abnormal sounds (such as crackles and rhonchi) in your lungs. They will also check for fever, respiratory rate, and heart rate.
• Chest X-ray: This is the most common test used to confirm pneumonia. The X-ray can clearly show areas of infection (like white spots) in the lungs.
• Blood tests: A full blood count (FBC) can show if there is an infection (an increase in the number of white blood cells) and how severe it is. A test called C-Reactive Protein (CRP) can also give an idea of ​​the severity of the infection. Sometimes a blood culture may also be done, especially if the infection is severe.
• Sputum culture and Gram stain: If you have phlegm, this test can be done to take a sample of the phlegm and find out what germ is in it. This will make it easier to give the right medicine for that germ.
• Pulse Oximetry: A small clip-like device is attached to your finger to measure the oxygen saturation in your blood. This can be low in pneumonia (normally it should be above 95%).

In some severe cases, special tests may be needed, such as a CT scan (of the chest), a pleural fluid culture, or a bronchoscopy. But most of the time, pneumonia can be diagnosed with the tests mentioned above.

What are the treatments for pneumonia?

The treatment for pneumonia depends on factors such as the cause (bacterial or viral), your age, overall health, and the severity of your symptoms.

• For bacterial pneumonia: Your doctor will often prescribe antibiotics . It is important to take these medications exactly as your doctor tells you, for the full duration of your treatment. Do not stop taking them just because you feel better. Doing so may cause your infection to get worse or cause antibiotic resistance.
• For viral pneumonia: Antibiotics do not work against viruses. For some viral pneumonias (such as those caused by influenza), antiviral drugs can be given within the first 48 hours of the illness. However, most viral pneumonias resolve on their own within a few days or weeks. It is important to get plenty of rest and fluids (water, soup, fruit juice) during this time.
• For fungal pneumonia: Antifungal drugs are used for this.

In addition, medications are also given to control symptoms:

• Reduce fever, reduce pain: something like paracetamol.
• Cough medicine: Sometimes doctors don't prescribe cough suppressants because coughing is a natural way to clear mucus from the lungs. If there is a lot of mucus, they may prescribe expectorants to thin it out a bit.

At home? At the hospital?

Most people can recover from pneumonia at home with treatment. However, if your condition is severe, such as difficulty breathing, low blood oxygen levels (below 92% on a pulse oximeter), an older person (over 65 years of age), someone with other serious medical conditions, or a young baby (especially under 6 months old), your doctor may decide to hospitalize you. In the hospital, you may be given IV antibiotics, oxygen therapy, saline solution if needed, and other necessary treatments.

The most important thing is to listen to what the doctor says and get the right treatment. If you take the right medicine and get enough rest, you will start to feel better in a few days. But it can take a few weeks to fully recover.

Ways to avoid pneumonia

There is a saying that goes, "It's better to be safe than sorry after getting sick." Let's see what we can do to avoid pneumonia.

• Get Vaccines: There are vaccines against some of the bacteria and viruses that cause pneumonia.
• Pneumococcal vaccine: This protects against the bacteria Streptococcus pneumoniae. It is recommended for people over 65 years of age, children under 2 years of age, and people with certain chronic diseases.
• Influenza vaccine (Flu shot): Getting this vaccine every year can prevent the flu and can also protect against pneumonia caused by the flu.
• Get other childhood vaccines (such as the Hib vaccine and measles vaccine) on time.

It is very important to talk to your doctor about these vaccines and get the one that is right for you.

• Follow good hygiene practices:
• Wash your hands often with soap and water (for at least 20 seconds), especially before eating, after using the bathroom, after being sick, and after coming from outside. Use soap or an alcohol-based hand sanitizer.
• Cover your mouth and nose with a tissue or your elbow when coughing or sneezing. Throw used tissues in the trash immediately.
• Try to stay away from people who are sick. If you are sick, stay home to avoid spreading it to others.
• Avoid smoking: If you are a smoker, try to quit. Avoid breathing in smoke when you are around other people who smoke (passive smoking). Smoking damages the natural defense mechanisms of the lungs.
• Keep your immune system strong: Eat a healthy diet (vegetables, fruits, and whole grains), get enough sleep (7-8 hours a day), and exercise regularly. These things will increase your body's ability to fight off illness.
• Manage chronic diseases: If you have diseases like diabetes, heart disease, or asthma, follow your doctor's instructions to properly manage them.

These little things can make a big difference, right?

When should I see a doctor?

If you have one or more of the following symptoms, other than a common cold or fever that doesn't go away in a few days, see a doctor immediately.

• If you have severe difficulty breathing , or if your chest hurts when you breathe.
• If you have severe chest pain .
• If the fever does not go down for more than 3 days , or if the fever continues to be higher than 39 degrees Celsius (102 Fahrenheit).
• If you cough up blood .
• If your lips or fingernails turn blue (this is a condition called cyanosis, a sign that your blood is not getting enough oxygen).
• If there is confusion or changes in consciousness (especially in the elderly).
• If it feels like it's getting worse than before , or if it feels like it's much worse than a common cold.
• If you vomit frequently and cannot keep anything down.

If you have symptoms like these, especially in a young child (especially a baby under 2 months old), an elderly person, or someone with other chronic illnesses, it's best to take them to the doctor without delay. Sometimes starting treatment early can make a big difference.

In conclusion, remember this:

Okay, so we've talked a lot about pneumonia today, haven't we? Remember, pneumonia is an infection of the lungs. It can be caused by germs like bacteria and viruses. The main symptoms are cough, fever, and difficulty breathing.

The most important thing:

* If you suspect you have symptoms of pneumonia, see a doctor immediately. Do not self-treat.

* Take the medications prescribed by your doctor, especially antibiotics, exactly for the prescribed period and in the prescribed dosage. Don't stop taking them just because you feel better.

* Pneumonia can be largely prevented by getting vaccinated, practicing good hygiene (especially hand washing), and avoiding smoking.

* Get plenty of rest, eat nutritious foods, and stay hydrated.

Pneumonia is not something to be afraid of, but it is not something to be ignored either. If you get proper treatment, you can recover quickly. I wish you and your family good health!
