Upper respiratory infection (URI) is a condition, which involves illness, mainly caused by critical infection in the upper respiratory tract. This region includes the pharynx, larynx, nose and sinus. This infection causes diseases, such as tonsillitis (tonsils get inflamed), pharyngitis (causes sore throat) sinusitis (nasal passage becomes inflamed), laryngitis (voice box in your throat gets inflamed) and common cold.

Causes of upper respiratory infection (URI):
1. Both virus and bacteria cause upper respiratory infection (URI). The most common form of virus causing this infection is known as 'rhinovirus.'

2. The immune system of young adults and children are often very vulnerable. Hence, they are more likely to develop upper respiratory tract infection.

3. URI is also contagious and airborne in nature. So if a person comes in contact with an infected person suffering from URI, he/she is likely to develop this infection.

4. Not washing hands before meals can also cause upper respiratory infection because the virus can be transferred easily to the mouth and can travel into your system.

5. If you have any lung problem or heart disease, you are more likely to be susceptible to upper respiratory infection.

6. Those who already have inflamed tonsils can trigger tonsillitis by drinking any cold or spicy beverage like ice-creams or cold milkshakes.

7. Exposure to some flu or cold can cause pharyngitis. It can also be caused by second hand smoking.

8. Birth defects or structural defects in the nasal cavity or nasal polyps can cause sinusitis. Sometimes the inside part of the nose may get swollen due to common cold and block your ducts. This is a common cause for sinusitis.

Symptoms of acute upper respiratory infection:
1. Congestion in the lungs or nasal area.
2. Whooping cough
3. Running nose due to common cold.
4. Feelings of fatigue and lethargy throughout the day.
5. Your body will start aching without engaging in any physical exercise.
6. You can also lose consciousness in severe respiratory tract infections.
7. Difficulty in breathing.
8. Oxygen levels in blood drop down drastically.

Sometimes in worse cases, acute upper respiratory tract infection (URI) can also cause respiratory failure, respiratory arrest and congestive heart failure. Therefore, it is necessary to book an appointment with a doctor as soon as you start experiencing the above symptoms.

Acute Upper Respiratory Infection: Causes and Symptoms

Lung diseases are some of the most common diseases suffered by human beings throughout the world. Smoking and infections are responsible for most lung diseases. The lungs perform one of the most important functions of the body. It is also one of the most active organs in the human body and hence lung problems can arise due to problems in any other part of the body. Some of the most common and infectious lung diseases are discussed below.

1. Asthma
Asthma is a common long term disease which is characterized by reversible airflow obstruction and bronchospasm. The symptoms of asthma include coughing, shortness of breath and tightness of chest. These symptoms may occur frequently during a day and depending on the person, it may become worse during night or during a certain exercise.

2. Pneumonia
Pneumonia is another common lung problem which is suffered due to inflammation in the microscopic air sacs in the lungs known as alveoli. Symptoms of pneumonia include dry cough, chest pain, breathing problem and fever. Pneumonia is caused most commonly by viruses or bacteria. It is also caused by certain medications and conditions which are popularly known as autoimmune diseases. There are a number of vaccines available to prevent certain types of pneumonia. Other methods include hand washing and refraining from smoking.

3. Tuberculosis
Tuberculosis is a very infectious disease which is caused by the bacteria mycobacterium tuberculosis. Although tuberculosis generally affects the lungs, but it has been known to affect other parts of the body as well. Symptoms of tuberculosis include cough containing sputum with blood, night sweats, fever and weight loss. Air is an active medium for spreading tuberculosis. This happens when people who already have tuberculosis sneeze, cough or speak. Infection occurs more in those who have hiv/aids or those who smoke. Prevention of tuberculosis includes staying away and keeping those who are at high risk, early detection and treatment and vaccination.

4. Mesothelioma
Mesothelioma is a type of cancer which affects the lungs. It affects the lining of the lungs and chest wall. Symptoms of mesothelioma include shortness of breath, swollen abdomen, cough, chest pain, weight loss and general lethargy. Mesothelioma is caused mainly due to exposure to asbestos. Those people who mine asbestos, produce products from asbestos, work with asbestos products are at high risk. Mesothelioma also results from genetical problems and due to infection caused by the simian virus 40.

5. Pulmonary embolism
This is a disease caused due to blockage of an artery in the lungs by a substance which has travelled from another part of the body by the bloodstream. Symptoms of this disease include chest pain, breath shortness and coughing up of blood. There may also be signs of blood clot in the legs.

Types of Lung Diseases

Do you know about a condition called cystic fibrosis that makes your baby s skin taste very salty after birth? The condition changes over time, in which the body makes sweat and mucus, and also affects the digestive system and lung functioning. The condition generally occurs because of a flawed gene. This is a severe and life-threatening disease that affects different people in different ways.

Causes
The gene, called CTFR is present in all humans. It makes a protein that controls the amount of water and salt, which get moved in and out of your cells. In the case of cystic fibroids, the CTFR gene is broken. This happens when a person inherits two bad copies of this specific gene. One bad CFTR gene may cause your cells to make the wrong or imbalanced amount of water and salt. Because of this, your body becomes unable to get the supply of sufficient nutrients and oxygen that are lost through sweating.

Symptoms
There are several symptoms associated with cystic fibroids that include the following:

It is likely for you to cough up thin mucus, along with shortness of breath, and wheezing.
The development of polyps in your nose is indicated.
Sinus infections, pneumonia, or bronchitis may occur.
Your stool may be oily, bulky, and with a foul odor.
Liver diseases and gallstones may develop later in life because of cystic fibroids.
Treatment
There is no certain treatment for cystic fibroids. However, there are various treatment procedures that are used for providing relief to the symptoms of the condition. This allows an affected patient to breathe easily, feel better, and experience lesser stomach infections. You can opt for airway clearance technique that helps you with your breathing. The procedure involves the clearance of mucus from your lungs. This procedure is carried out in several ways and special devices may be used during the proceedings.

Certain inhaled drugs like steroids, salt solutions, and antibiotics are used for thinning your mucus layers, and for clearing lung infections.
If your pancreas do not work properly, you may be prescribed enzyme pills for the digestion of fats and protein, and for the absorption of more nutrients from the food you consume.
You may also be prescribed vitamin A, D, and E supplements for getting these nutrients, which are not being absorbed by your intestine.
You must consult a doctor on experiencing any symptom of cystic fibrosis in your baby. This will allow the condition to be diagnosed at an early stage, thereby preventing further worsening.

Cystic Fibrosis - 5 Strange Signs You Must Know About!

Interstitial Lung Disease (ILD) is a term which is used for a large collection of disorders that can cause scarring of the lungs. The scarring gives rise to stiffness in the lungs that make it troublesome for breathing. Some of the examples of ILDs include Asbestosis, Hypersensitivity Pneumonitis, Sarcoidosis, and Idiopathic Pulmonary Fibrosis.


Causes -
ILDs could be caused by being exposed to dangerous chemicals, medical treatments, and certain medications. In nearly all cases, the result is unspecified. In several cases, it can be reduced by certain medications. Many drugs can harm the lungs, especially heart medications which are used to treat irregular heartbeats and hence might damage the lung tissue. Chemotherapy drugs that kill cancer cells, can also harm lung tissue.
Anti-inflammatory drugs and some antibiotics can also cause lung damage. The desecrate of the lung from many ILDs is progressive and irreversible which means it gets adverse over time. So, doctors often recommend lung transplant for the people having interstitial lung disease.

Symptoms -
The earliest symptoms and signs of interstitial lung disease are dry cough and shortness of breath at rest.

Risk Factors -
  Chemotherapy and Radiation: Using therapy drugs or having radiation treatments to chest makes it more likely to develop lung disease.
  Age: Interstitial lung disease affect adults more, although children and infants sometimes develop this disorder.
  Smoking: It occurs mostly in people who have a history of smoking. Active smoking might make the condition worse.
  Gastroesophageal Reflux Disease: If a person is having indigestion or uncontrolled acid reflux, he or she may be at risk of Interstitial Lung Disease (ILD).

Treatment -
The lung scarring or the lung fibrosis that occurs in interstitial lung disease cannot be changed and therapy will not every time be effective in stopping or finishing the ultimate development of the disease. Some treatments might slow the progression of this disease or improve symptoms temporarily. Others may help to improve quality of life. Many different scarring disorders have no proven therapies.

  Oxygen Therapy: Lung damage cannot be stopped by the oxygen therapy, but it can improve the sense of well-being and sleep because when sleeping, one receives more oxygen. It can also relax blood pressure in the right part of the heart. It can make breathing easier. Oxygen therapy can also lessen or prevent difficulty from low blood oxygen levels.
  Pulmonary Rehabilitation: Pulmonary rehabilitation not only improves daily functioning but also helps in live life fully to the people who are suffering from Interstitial Lung Disease. Pulmonary rehabilitation programs focus on breathing techniques which enhance lung efficiency, physical exercise to enhance endurance, nutritional counseling, and emotional support.

Take Away -
Interstitial Lung Disease (ILD) is a group of disorders that can be the cause of scarring of the lungs, which ultimately lead to lung damage. This condition affects more adults than children. The progression of this condition can be curtailed by adopting certain therapies.

What Is Interstitial Lung Disease?

Interstitial lung disease is an umbrella term that includes a number of conditions that causes scarring of the tissues of the lungs. This scarring can hamper your breathing and therefore cause less oxygen to be present in your blood.

When you are exposed to hazardous materials like asbestos for long periods, you can get interstitial lung disease. Even autoimmune conditions like rheumatoid arthritis can result in this condition. 

Once the tissues of your lungs are scarred, chances are that it can t be reversed. While medications can slow the progress of the but you won t be able to regain the full functionality of your lungs. In such cases, you can consider a lung transplant.

What are the signs?

You will difficulty in breathing   it may be aggravated when you exert yourself or you may experience shortness of breath during rest periods. A dry cough is another sign of this condition.

What causes it?

Interstitial lung disorders occur when you ve had an injury in your lungs that set off an abnormal healing process. With the healing not happening in a normal way, the tissues around your air sacs tend to thicken and get scarred. The does not allow oxygen to get into your blood.

There are certain triggers for this condition  

If you are exposed to certain pollutants or toxins like silica dust, bird dropping and grain dust for long periods.

Medications like chemotherapy drugs, anti-inflammatory drugs and heart medications.

If you have the following medical disorders   scleroderma, rheumatoid arthritis, mixed connective tissue disease, dermatomyositis, Sjogren's syndrome and sarcoidosis.

What is the treatment? 

First, a doctor will carry out diagnostic tests to identify the cause of the problem. The following tests are usually performed  

Blood tests to detect autoimmune responses to pollutants

Imaging tests like CT scan and echocardiogram

Tests like oximetry and spirometry to determine your lung s capacity

Surgical biopsy and bronchoscopy to analyse your lung tissue

Once the diagnosis is done, the doctor can suggest any one of them or a combination of the following methods  

1. Medications 

Corticosteroids are used to suppress the immune system. GERD can also damage your lungs, so you may be given medicines to reduce stomach acid if you have an excess of it.

2. Oxygen therapy

Oxygen therapy can help you with breathing and help you sleep better. But it won't stop damage to the lung tissues.

3. Pulmonary rehabilitation

Pulmonary rehabilitation can help you perform your daily tasks without any hitch. It includes exercise, breathing techniques, eating healthy and emotional support.

Surgery

If nothing else works, then the doctor may recommend a lung transplant. 

Moreover, there are certain lifestyle remedies that you can adopt  

Avoid smoking as it can aggravate your condition.

Eat a healthy and nutritious diet.

Take vaccines for respiratory infections like the flu and pneumonia.

The best way to deal with this disorder is to not have it at all. But with proper treatment, your symptoms can be reduced.

Interstitial Lung Disease - Know More!

The lungs are responsible for taking in and filtering out oxygen which is then supplied to the body via circulation. They are also responsible for removing the carbon dioxide from the body. This happens through breathing, and though no effort is required, when the function is impaired, the entire body system takes a toll.

Lung function can be impaired by a multitude of issues including infections like pneumonia, chronic diseases like COPD and pulmonary hypertension, heart conditions like a congestive failure, etc. While the acute cases would go off once the infection is treated, the long-term conditions are helped by physiotherapy in addition to medications.

The lungs are made up of elastic tubules and have the ability to hold secretions. Therefore training the lungs to improve their function via exercise can help improve overall lung function. Some of the routine exercises are simple ones as below.

Active breathing: The patient is taught to breathe in a more aware manner so that the lungs take in air to their maximum ability.
Postural drainage: The lungs are like containers for mucus, and over a period of time, they need to be drained. Depending on where the fluid accumulation is, the patient is taught to lie in various positions so that it can be drained, allowing for instant relief.
Nasal saline rinse: This helps in clearing the secretions and also the saline provides an antibacterial effect to clear off residual infection. Clearing sputum is highly critical for reducing chances of repeat infections and hospitalizations.
Peripheral and respiratory muscle training: Though it goes unnoticed, breathing also involves neck and shoulder muscles and strengthening these is also essential for effective breathing.
Multiple studies have shown that physiotherapy plays a vital role in lung rehabilitation. As noted above, while the benefit may be not very evident in short-term lung impairment, it makes a significant difference in long-term and chronic conditions like COPD, pulmonary hypertension, and even congestive heart failure. Lung rehab has shown to produce the following changes:

Reduce episodes of breathlessness and fatigue. A person can gradually resume his normal chores without too much assistance.
Help in clearing secretions, which can worsen congestion and breathlessness.
Increase overall quality of life. There could be even people who cannot do routine activities like walking to the bathroom. They could be benefitted with pulmonary rehabilitation.
Reduce the number of hospitalizations due to mucus accumulation and breathlessness.
Improve exercise tolerance. It is well known and proven that those who exercise on a regular basis can improve lung function over a period of time.
