What is the difference between bronchitis and pneumonia?

 What is the difference between bronchitis and pneumonia?

Although both bronchitis and pneumonia are problems related to the lungs, bronchitis affects the airways and pneumonia affects the air cells.

Although both these diseases have similar symptoms like cough, fever and difficulty in breathing, pneumonia can be more serious.

If there is a cough or fever and the chest feels full due to phlegm, this may be a sign of bronchitis or pneumonia. Both of these are problems related to the lungs and their symptoms are similar to each other.

Both these infections affect the breathing process and coughing is common along with severe pain. The fact that the symptoms of bronchitis and pneumonia are similar does not mean that these two diseases are the same. There is a very important difference between the two.

What is bronchitis?

Bronchitis is not always due to infection alone; It can also be caused by allergies, dust, smoke, pollution or autoimmune. Therefore, it is wrong to understand it only by connecting it with infection.

Bronchitis is an inflammation of the bronchial tubes in the lungs. When these tubes swell, their inner lumen narrows, causing difficulty in breathing. In addition, there are symptoms such as continuous coughing, feeling of phlegm in the chest, and a tickling sensation in the throat.

When the mucus gland is active, more phlegm is produced, which aggravates the problem. Bronchitis is of two types—acute (short-term) and chronic (long-term).

What is pneumonia?

Pneumonia is an infection in the alveoli of the lungs. In this case, liquid or pus can fill inside the alveoli, which hinders oxygen exchange. It is usually caused by a viral, bacterial or fungal infection, not an allergy.

What are the causes of bronchitis and pneumonia?

due to bronchitis

Bronchitis is an infectious condition and many people are affected by it. Usually it is not serious. But chronic bronchitis can gradually reduce lung function and can be life-threatening.

Due to acute bronchitis

Viral infection: Bronchitis caused by a virus causes cough and difficulty in breathing.

Bacterial infection: Bacteria can also cause bronchitis and increase breathing problems.

Fungal infection: Sometimes fungal infection can also cause this problem.

Other causes: Exposure to substances that irritate the lungs such as smoking, dust, fumes, vapors, and air pollution can also cause bronchitis.

Due to chronic bronchitis

Chronic bronchitis is caused by persistent swelling in the airways. This is a form of 'Chronic Obstructive Pulmonary Disease'. According to the US National Institutes of Health, bronchitis is an inflammation of the mucus membrane while pneumonia is an inflammation of the lung tissue, which can be caused by a bacterial, viral or fungal infection.

due to pneumonia

Pneumonia is caused by a viral, bacterial or fungal infection. In addition, pneumonia can also occur when some harmful substances enter the lungs. When these bacteria or irritants reach the alveoli, pneumonia develops.

Types and causes of pneumonia

Bacterial Pneumonia: The most common type of pneumonia caused by bacteria. Its main type is pneumococcal pneumonia, which is caused by the bacterium Treptococcus pneumoniae.

Viral Pneumonia: Caused by viruses like influenza.

Mycoplasma Pneumonia: It is caused by a microscopic parasite called Mycoplasma, which has some characteristics of both viruses and bacteria.

Fungal Pneumonia: Pneumonia caused by fungal infection.

Symptoms of bronchitis and pneumonia

The symptoms of both diseases are similar to a large extent, but some symptoms can help distinguish the difference.

Similar symptoms

- Acute cough and expectoration

- White, green or yellow phlegm

- Fever or chills

- Shortness of breath or wheezing

-Feeling of chest tightness

- Sore throat

More common symptoms of pneumonia

-Discomfort or confusion, especially in elderly people

- Abnormally increased or decreased breathing rate

- Nausea or vomiting

- Loss of appetite

- Chills or muscle aches

Why is it difficult to tell the difference?

The symptoms of bronchitis and pneumonia are very similar. Therefore, it is difficult to distinguish based on simple symptoms only. Medical examination is necessary for correct diagnosis.

In which case should you consult a doctor immediately?

- Difficulty breathing

- Inability to stop coughing

- High fever

-Symptoms do not improve or recur frequently even after treatment

-Seeing blood in the phlegm

- Acute chest pain

-Feeling extremely weak

- Pre-existing serious illness and increased breathing problems

Breathing problems can quickly become serious, so emergency treatment may be necessary in such cases.

How is bronchitis and pneumonia diagnosed?

The doctor first understands the symptoms, their duration and the patient's health history. Then the stethoscope listens to the sound of the lungs. If necessary, the following tests can be performed.

Sputum Culture: Bacterial infection is detected by testing a sputum sample.

Chest X-ray: Shows the condition of infection in the lungs and helps to differentiate between bronchitis and pneumonia.

Pulse oximetry: The amount of oxygen in the blood is measured.

Pulmonary function test: How much air the lungs can take in and out is checked.

Treatment of bronchitis

Car treatment disease

Depends on the loan. In most cases of acute bronchitis, it is viral, so antibiotics do not work.

- Adequate rest

-Abundant fluid intake

-Fever or pain reliever medicine

- Cough medicine

-Using a humidifier or steam at night

- If the cause is bacteria, the doctor can give antibiotics.

Chronic bronchitis

It may not be completely cured, but the symptoms can be controlled

– Inhaler

-Pulmonary rehabilitation therapy

Medicines to reduce swelling

- Stop smoking completely

Treatment of pneumonia

The treatment of pneumonia depends on its type.

Bacterial pneumonia: Antibiotics

Fungal pneumonia: Antifungal drugs

Viral Pneumonia: Although there is no specific viral drug, treatment is given according to the symptoms.

Also:

-Fever or pain reliever medicine

- Consuming a lot of junk food

- Adequate rest

- Use a humidifier or steam to thin the phlegm

- Stay away from smoking

- In severe cases, hospitalization may be required

How is lung cancer treated? Let's go into detail

 How is lung cancer treated? Let's go into detail

Surgery can be an important treatment when the cancer is confined to the lungs and the patient can tolerate surgery.

Lung cancer may not have symptoms in the early stages, so if you have a cough, chest pain, or blood in your sputum, you should see your doctor.

Lung cancer is one of the most serious health problems worldwide. Since there may be no obvious symptoms in its early stages, many people are diagnosed only after the disease has spread. People who smoke for a long time are especially at risk. However, even non-smokers can get lung cancer. Timely diagnosis of the disease and starting the correct treatment according to the type and condition of cancer is considered very important for the treatment results.

Lung cancer is mainly of two types, non-small cell lung cancer and small cell lung cancer. Non-small cell lung cancer is seen relatively more. These two types of cancer may differ in growth, spread and treatment. Therefore, all patients with lung cancer are not treated in the same way.

Why does lung cancer occur?

The most important risk factor for lung cancer is smoking. Consumption of cigarettes, bindis and other tobacco products increases its risk. Second-hand smoke can also increase the risk of living with a smoker for long periods of time.

Similarly, exposure to air pollution, long-term contact with some industrial chemicals, radon gas, and some types of dust or toxic substances in the workplace can also increase the risk. Although the risk increases with age, lung cancer can occur in people of any age.

What are the initial symptoms?

In the early stages of lung cancer, there may be no symptoms. Symptoms may include prolonged coughing, changes in the appearance of an old cough, difficulty breathing, chest pain, blood in the sputum, frequent lung infections, changes in voice, abnormal weight loss, loss of appetite, and excessive fatigue.

The presence of any of these symptoms does not necessarily mean that cancer is present. These symptoms can also be seen in many other diseases. But if the symptoms persist for a long time, it is necessary to check with a doctor.

How is cancer diagnosed before treatment?

If lung cancer is suspected, the doctor will conduct necessary tests after obtaining information about the patient's health history, smoking status and symptoms. Usually, imaging tests such as chest X-rays and CT scans can look for abnormal lumps or other changes in the lungs.

But imaging tests alone do not definitively confirm cancer. Biopsy is done if necessary. In this, tissue or cells are removed from the suspicious part and tested in the laboratory.

In some cases, the necessary tissue can be removed by viewing the inside of the trachea and lungs through bronchoscopy. In some cases, a sample is taken from the lung nodule through a needle. Sputum cytology can also be done to see if there are cancer cells in the stool.

Why is it important to find out the stage of cancer?

The next important step after cancer is confirmed is staging. That is, how big the cancer is, whether it has spread to nearby lymph nodes and whether it has reached other parts of the body is found out.

For this, tests such as CT scan, PET scan, MRI of the brain can be done as needed. Knowing the stage of cancer makes it easier to plan the right treatment.

Generally, lung cancer is classified into different stages from early stage to advanced stage. In the early stages, the cancer may be limited to the lungs, while in the advanced stage, it may spread to nearby lymph nodes or other parts of the body.

Why are biomarker and gene testing important?

Especially in non-small cell lung cancer, molecular or biomarker tests can be important in choosing treatment. Cancer cells can be tested for certain gene changes such as EGFR, ALK, ROS, BRAF, KRAS, MET, RET, and NTRK. Similarly, in some cases, biomarkers such as PD-L1 are also tested.

Such tests help the doctor to decide which of the targeted drugs or immunotherapy might be useful. So just knowing the name of the cancer is not enough when the cancer is confirmed; It may also be important to understand its biological characteristics.

How is lung cancer treated?

Lung cancer treatment is not the same for all patients. Treatment is selected based on the type of cancer, stage, gene mutation, tumor location, patient's age, lung function and overall health.

1. Surgery

Surgery can be an important treatment when the cancer is confined to the lungs and the patient can tolerate surgery. In surgery, the cancerous part is removed.

Wedge resection or segmentectomy can be done in small tumors. A lobectomy is performed in cases where the entire lobe with cancer needs to be removed. In special circumstances, pneumonectomy is performed when the entire lung needs to be removed. During surgery, nearby lymph nodes can also be removed to check if the cancer has spread.

2. Chemotherapy

In chemotherapy, drugs are used to stop or destroy the growth of cancer cells. Medicines are usually given intravenously, but some medicines can also be taken orally are Chemotherapy may be used to reduce the size of the tumor before surgery or to destroy cancer cells that may remain in the body after surgery. In advanced cases, it is also used to control the growth of the disease and reduce the symptoms.

Side effects such as fatigue, nausea, loss of appetite, hair loss and decrease in the number of blood cells may occur during chemotherapy. But not all side effects are seen in all patients and many can be controlled with medication and other supportive treatments.

3. Radiation therapy

In radiation therapy, an attempt is made to destroy or control cancer cells by targeting high-energy rays at the cancerous part. It can be used before or after surgery. Radiation may be the main treatment for some early cancers that cannot be operated on. In advanced cases, radiation can also be used to reduce pain, bleeding, or other symptoms caused by the spread of cancer.

4. Stereotactic body radiotherapy

Stereotactic body radiotherapy is a very precise technique of radiation therapy. In this, a high dose of radiation is targeted at a specific location with a small tumor and an attempt is made to protect the surrounding healthy tissue as much as possible. This treatment may be useful in some early-stage non-small cell lung cancer patients who cannot undergo surgery.

5. Targeted drug therapy

Targeted therapy can be used if certain gene changes or other specific biological changes are found in cancer cells. Its purpose is to target specific processes that cause cancer to grow compared to normal cells. But targeted drugs are not effective for all patients who do not have gene changes. Therefore, it is important to test the necessary biomarkers before treatment.

6. Immunotherapy

Immunotherapy helps the body's immune system to work effectively against cancer cells. In some types of advanced lung cancer, immunotherapy may be used alone or in combination with chemotherapy. The doctor decides which patient to give this treatment based on the type of cancer, stage and necessary biomarker tests.

7. Supportive care is also important during treatment

Cancer treatment is not only about removing the tumor or stopping the growth of cancer. Management of problems such as pain, difficulty breathing, nausea, loss of appetite, weakness and mental stress during treatment is also important.

This is called supportive or palliative care. Such care can be initiated not only at the end of treatment but also as needed along with cancer treatment. Its purpose is to improve the patient's quality of life and control symptoms.

Why is regular follow-up necessary after treatment?

Even after the treatment is completed, regular follow-up is necessary. The doctor can perform a physical examination, necessary imaging and other tests based on the patient's condition. From this, it can be evaluated whether the cancer has reappeared, whether the treatment has long-term effects, and whether additional treatment is necessary.

What can be done to prevent lung cancer?

Not all lung cancer risks can be prevented, but many significant risks can be reduced. One of the most important steps a smoker can take is to quit smoking. Stay away from other people's smoke as much as possible.

People who come into contact with dust, chemicals or other hazardous substances in the workplace must use the necessary protective equipment. In case of high air pollution, it is also useful to take measures to reduce the risk.

Treatment is not the same for everyone

The treatment of lung cancer is now more developed than ever before. New treatments such as surgery, chemotherapy, and radiation therapy, along with targeted drugs and immunotherapy, have expanded treatment options for many patients. But the treatment is not the same for all patients. Based on the type of cancer, stage, biomarkers, patient's health condition and response to treatment, the expert doctor decides the treatment plan.

Therefore, symptoms such as prolonged coughing, blood in the sputum, chest pain, difficulty in breathing or weight loss without any reason should not be ignored. Medical examination should be done on time.
