What is pneumonia? Pneumonia is an infection of 1 or both of the lungs caused by bacteria, viruses, or fungi. It is a consequential infection in which the air sacs fill with pus & another liquid. What are the symptoms of pneumonia? The symptoms of bacterial pneumonia include: Before symptoms of viral pneumonia are the…
What is emphysema? Emphysema is a lung situation that causes shortness of breath. In people with emphysema, the air pouch in the lungs (alveoli) is damaged. Over time, the inner walls of the air pouch weaken and rupture — creating larger air spaces instead of many small ones. This decreases the surface area of the…
What is acute bronchitis? Bronchitis is inflammation of the breathing tubes. These airways are also called bronchi. This inflammation causes increased mucus production and another change. Although there are several various types of bronchitis, the most common are acute and chronic. Acute bronchitis may be called a chest cold. Most symptoms of acute bronchitis last…
Key facts Chronic obstructive pulmonary disease (COPD) is the 3rd leading cause of death worldwide, causing 3.23 million deaths in 2019. Nearly 90% of Chronic obstructive pulmonary disease and COPD deaths in those under 70 years of age happen in low- and middle-income countries (LMIC). Early diagnosis & treatment, involving smoking cessation support, is needed…
What is polymyositis? Polymyositis is an inflammatory muscle disease that causes muscle weakness. Myositis means inflammation of the muscle. Commonly, polymyositis affects the muscles that are closest to the trunk of the body. Eventually, people with polymyositis have trouble when rising from the sitting position, climbing stairs, lifting objects, or reaching overhead. In certain cases,…

According to the Centers for Disease Control & Prevention (CDC), about of 25 million Americans, a trusted source has asthma. It is the most usual chronic condition…
What is Nerve conduction velocity (NCV)? Nerve conduction velocity (NCV) also called as electroneurography, Energy, or nerve conduction study, a nerve conduction velocity (NCV) test is a measurement of the speed of conduction of an electrical impulse through a nerve. Nerve conduction velocity (NCV) can determine nerve damage and destruction. During the test, the nerve…
What is electromyography (EMG)? Electromyography (EMG) measures muscle response or electrical activity in reaction to a nerve’s stimulation of the muscle. The test is used to assist detect neuromuscular abnormalities. During the test, one or more little needles (also called electrodes) are inserted through the skin into the muscle. The electrical activity taken up by…
