Journal of Respiratory Diseases and Medicine spotlight on diverse range of topics like acute bronchitis, asthma, chronic inflammatory lung diseases, chronic obstructive, emphysema, pulmonary disease, influenza, pleural cavity diseases, paediatric respiratory diseases, pulmonary vascular diseases, respiratory tract infections, respiration physiology, respiratory medicine, respiratory tumours, … Diseases of the respiratory system may affect any of the structures and organs that have to do with breathing, including the nasal cavities, the pharynx (or throat), the larynx, the trachea (or windpipe), the bronchi and bronchioles, the tissues of the lungs, and the respiratory muscles of the chest cage. Much rarer, unless you count choking and drowning, are conditions that affect the larger passageways of the lungs such as the trachea and the bronchi. Diseases of the respiratory system occur primarily in the bronchioles and the alveoli. In addition, severe chest pain may be caused by the spread of malignant disease to involve the pleura or by a tumour that arises from the pleura itself, such as in mesothelioma. How about medical conditions? Asthma is a chronic disorder involving soreness and swelling of the interior airway walls. Facts about smoking and respiratory diseases. Researchers monitor for next novel influenza strain. The brain? The two main types of COPD are chronic bronchitis and emphysema.

Consequently, air is obstructed from circulating freely in the lungs and cannot be expired. Chronic diseases, such as asthma, are persistent and long-lasting. Leads to limited airflow into and out if the lungs, with increased difficult in breathing Your airways narrow and make too much mucus. Fortunately, pain of this severity is rare. This sensation, of complex origin, may arise acutely, as when a foreign body is inhaled into the trachea, or with the onset of a severe attack of asthma. In an asthma attack, the inflamed airways become irritated during inhalation. Acute respiratory distress syndrome (ARDS) occurs when fluid builds up in the tiny, elastic air sacs (alveoli) in your lungs.

Hemoptysis is also a classic sign of tuberculosis of the lungs. Airborne allergens and viral or bacterial infections can inflame the mucous membranes. Acute pleurisy with pain may signal a blockage in a pulmonary vessel, which leads to acute congestion of the affected part. The respiratory system diseases are the diseases that occur in the lungs or the human airway, which affects human respiration. This interferes with oxygen absorption, making the patient feel short of breath. Emphysema destroys the walls of the alveoli of the lungs, resulting in a loss of surface area available for the exchange of oxygen and carbon dioxide during breathing. Various conditions affect different parts of your respiratory system and hinder your ability to … Emphysema (COPD) – Chronic Obstructive Pulmonary Disease, of which emphysema is one of, results in progressive destruction of the air sacs in the lungs and loss of respiratory membrane for oxygen exchange. Refer any person meeting one of the following criteria for medical evaluation: Any person with respiratory symptoms that are … Smooth muscles in the airway wall tighten, resulting in bronchoconstriction (constriction of the bronchiole tubes) and excess mucus production. Loss of appetite and loss of weight, a disinclination for physical activity, general psychological depression, and some symptoms apparently unrelated to the lung, such as mild indigestion or headaches, may be diverse indicators of lung disease. There are two types of respiratory diseases and disorders: infectious and chronic.

This produces symptoms of shortness of breath, coughing, and wheezing. It is commonly dyspnea that first causes a patient to seek medical advice, but absence of the symptom does not mean that serious lung disease is not present, since, for example, a small lung cancer that is not obstructing an airway does not produce shortness of breath. Some lung diseases can lead to respiratory failure. Occupational respiratory disorders are defined as any disorder … Lung Cancer. of Health and Human Services Office on Women's Health Pulmonary infections are most commonly bacterial or viral. When this occurs, if the right ventricle that pumps blood through the lungs is functioning normally, the lung capillaries become engorged, and fluid may accumulate in small alveoli and airways.

See our privacy policy for additional details. In some lung diseases, the first symptom may be a swelling of the lymph nodes that drain the affected area, particularly the small nodes above the collarbone in the neck; enlargement of the lymph nodes in these regions should always lead to a suspicion of intrathoracic disease.

Thus, a hip fracture from bone metastases, cerebral signs from intracranial metastases, or jaundice from liver involvement may all be the first evidence of a primary lung cancer, as may sensory changes in the legs, since a peripheral neuropathy may also be the presenting evidence of these tumours. The symptoms of lung disease are relatively few. During an asthma attack, smooth muscles that surround the airways spasm; this results in tightening of the airways, swelling and inflammation of the inner airway space (lumen) due to fluid buildup and infiltration by immune cells, and excessive secretion of mucus into the airways. Respiratory System: Disease # 8.

Respiratory diseases affect millions of people in the United States. More often, it is insidious in onset and slowly progressive. Because the symptoms of lung disease, especially in the early stage, are variable and nonspecific, physical and radiographic examination of the chest are an essential part of the evaluation of persons with these complaints. The shortness of breath may vary in severity, but in diseases such as emphysema (see below Pulmonary emphysema), in which there is irreversible lung damage, it is constantly present. Respiratory diseases range from mild and self-limiting, such as the common cold, to life-threatening entities like bacterial pneumonia, pulmonary embolism, and lung cancer.

More than 25 million people in the United States have asthma. In emphysema, the alveoli in the lungs are damaged. In fact, smoking is directly responsible for almost 90% of lung cancer and COPD deaths. Severe fibrosis of the lung, resulting from occupational lung disease or arising from no identifiable antecedent condition, may also cause severe and unremitting dyspnea. The second most important symptom of lung disease is dyspnea, or shortness of breath. The narrow, obstructed airways restrict normal airflow into and out from the lungs. Millions of people are suffering from genetic or environmental built up respiratory conditions. Literally, “an imperfect expansion” in Greek.

The bane of long term smokers. Once inhaled, the flu virus moves into the respiratory tract and enters epithelial cells that line the airways. The pain disappears when fluid accumulates in the pleural space, a condition known as a pleural effusion. Acute bronchitis; Bronchiolitis Chest trauma can result in a puncture or tear in lung tissue, however. During normal breathing, inhaled air travels through two main channels (primary bronchi) that branch within each lung into smaller, narrower passages (bronchioles) and finally into the tiny, terminal bronchial tubes. Diseases and conditions of the respiratory system fall into two categories: viruses, such as influenza, bacterial pneumonia, enterovirus respiratory virus; and chronic diseases, such as asthma and chronic obstructive pulmonary disease (COPD). You’ll need to know a lot to answer 44 of the hardest questions from Britannica’s most popular quizzes about health and medicine.

They range from acute infections, such as pneumonia and bronchitis, to chronic conditions such as asthma and chronic obstructive pulmonary disease. Healthy People 2030 focuses on increasing prevention, detection, and treatment of respiratory diseases. Emeritus Professor of Medicine, University of British Columbia, Vancouver. The inflammation blocks the sinus openings and prevents the mucus from draining. In chronic bronchitis, inflamed airways constrict and generate excess mucus, making it hard to breathe. With the ability to develop in any part of the lungs, this cancer is difficult to detect.
