Your lungs are directly affected by the outside environment. That means germs, fumes, smoke, and other pollutants can harm your respiratory system, contributing to a variety of lung infections and diseases. According to the U.S. National Library of Medicine, the common cold, which is an UPPER respiratory infection, is the most prevalent illness in the United States-there are a reported 1 billion colds each year. Colds are usually transmitted when a person inhales germs or touches a surface covered in germs and then touches their eyes or nose. Symptoms begin within a few days of the infection and can last up to two weeks. Between 5 and 20 percent of people in the U.S. get THE FLU annually. Most of the time people battle through the body aches, chills, cough, fever, headache, and sore throat that the flu causes. But this viral upper respiratory infection is responsible for 226,000 hospitalizations and up to 49,000 deaths in the U.S. EACH year. If people with asthma and chronic obstructive pulmonary disease get the flu it can seriously EXACERBATE their symptoms. Pneumonia is a lung infection that occurs when viruses or bacteria affect the lungs. Typical symptoms include coughing, difficulty breathing, fever, and chills. Those most likely be affected are people with preexisting health problems, such as COPD, those who smoke, or those who are older than 65 or younger than 2. Pneumonia is treated with antibiotics -- if it's caused by bacteria. Patients can reduce their symptoms by breathing in steam from a humidifier or a hot shower, drinking plenty of fluids, AND getting plenty of rest. A vaccine for children and adults 50 and older protects against more than 20 strains of the disease.Sometimes caused by the same viruses that triggers the flu and colds, bronchitis inflames the bronchial tubes, which are responsible for transporting air to and from your lungs. As a result, people start wheezing, and get chest pain, a low fever, shortness of breath, and a wet cough. Acute bronchitis lasts from a few days to 10. In rare instances it is caused by bacteria. Only then is it appropriate to treat it with an antibiotic. Chronic bronchitis is caused by inflammation of the airways, not from an infection, but from long-term exposure to tobacco smoke, dust, fumes, and air pollution. This form of the disease typically requires ongoing treatment and lifestyle changes to slow permanent damage the lungs.To avoid catching acute bronchitis or aggravating chronic conditions:-Try to avoid catching any respiratory infections by washing your hands frequently; avoiding crowds during the "cold and flu season"; never sharing food or drinks and getting the flu vaccine every year. Also, ask your doctor if you would benefit from the pneumonia vaccine.Learn more about respiratory conditions by watching other videos in this series.More »

You're probably accustomed to the sniffles and sore throats that usually go along with colds. But pneumonia is an infection of the LUNGS, so the symptoms differ.Pneumonia OFTEN begins when the bacteria or viruses infecting your NOSE and THROAT penetrate your lungs. And yes, you CAN catch it from someone else. No matter its ORIGIN, both viral AND bacterial pneumonia cause the lungs to become inflamed and filled with pus and fluid. The symptoms include: Coughing, which may or may not produce mucus. Mild or HIGH feverShaking CHILLSShortness of breath Heavy SWEATINGHeadacheLOSS of appetiteLOW energySharp CHEST painIn SEVERE pneumonia, it's possible to experience a worsening cough, rapid breathing, rapid pulse, breathlessness, bluish color in their lips and nails and mental confusion. MILD cases of pneumonia often go away after 2 weeks, but patients with severe cases will take longer to recover. Pneumonia has the possibility to lead to VERY serious health problems, such as RESPIRATORY FAILURE. This occurs when pneumonia overwhelms the lungs, preventing them from doing their job. Patients with respiratory failure may have to be put on a ventilator. Acute respiratory distress syndrome is a severe form of respiratory failure that often results in death. Pneumonia can also lead to BACTEREMIA. Pneumonia-causing bacteria may enter the bloodstream, causing a body-wide infection and organ shutdown.PLEURAL EFFUSION develops in about 20 percent of pneumonia patients. It causes fluid build-up between the 2 layers of the pleural membrane that surrounds each lung. When the fluid becomes inflamed, it's called pleurisy. When it's infected, it's called empyema.In SERIOUS cases, AIR instead of fluid may build up between the pleural membranes, causing pneumothorax, or collapsed lung.Although pneumonia should in all cases be taken seriously, MOST adults and children recover fully.

Flus and colds are MISERABLE! But PNEUMONIA is often far more severe. In the US, more than a million people a year are hospitalized with pneumonia - which inflames the air sacs in the lungs so that they fill with fluid or pus, making it hard to breathe.People often wait until pneumonia gets severe before seeking help. It's understandable to see why, as pneumonia often presents as a very bad cold. Symptoms of pneumonia include fever, COUGH, shortness of breath, SWEATING, chills, chest pain, HEADACHES, muscle pain and fatigue. SEVERE symptoms include extreme breathlessness and respiratory FAILURE. If you've had cold symptoms, including fever, for more than 7 DAYS, go get checked out by your doctor.Pneumonia has over 30 distinct causes, including various fungal infections, chemical exposure, and many viruses. But most cases are triggered by pneumococcus or other bacteria. When pneumonia IS caused by a VIRAL infection - as it is for about a third of the cases-the flu is often to blame. Other viruses that cause pneumonia are the adenovirus, herpes simplex virus, and rhinovirus, which is behind the common cold. Among infants, the RESPIRATORY SYNCYTIAL VIRUS is the most common cause. While many cases of pneumonia are MILD to moderate, this infection is high-risk for the most vulnerable, including: young children, the elderly,smokers,people with a chronic illness, such as asthma, or who are immune-suppressed, such as anyone with HIV/AIDS, those who are on immune-suppressing MEDICATIONS, such as methotrexate andanyone who's recently had surgery or been in the hospital. Remember, you can CATCH pneumonia from other people, even if they DON'T have symptoms yet. To DIMINISH your risk, wash your hands frequently, DISINFECT doorknobs and countertops, and keep your immune system strong by eating healthy, QUITTING smoking, getting plenty of sleep and treat any respiratory infections promptly. DON'T neglect to receive a flu shot AND-if your doctor recommends it-- the pneumococcus vaccine. Take a look at other videos in this series to get details on pneumonia symptoms and treatments.More »

Walking pneumonia is so named because, UNLIKE more SEVERE forms of pneumonia, it DOESN'T knock you off your feet. Also known as ATYPICAL pneumonia, walking pneumonia is usually caused by one of three types of bacteria-Mycoplasma pneumoniae, Chlamydophila pneumoniae, or Legionella pneumophila. MYCOPLASMA pneumoniae is responsible for 15 to 50 percent of all pneumonia cases in adults.CHLAMYDOPHILA PNEUMONIAE is behind 5 to 15 percent of all pneumonia cases. It's RELATED to the bacteria that cause chlamydia, but the two diseases are NOT similar. Mycoplasma and chlamydophila trigger similar symptoms, including chills, cough, FEVER and shortness of breath. Other symptoms are chest pain, HEADACHE, loss of appetite, LOW energy, fatigue, muscle aches, and sweating. Less common symptoms of mycoplasma pneumonia include ear pain, EYE pain and rash. Pneumonia caused by Legionella pneumophila-also known as Legionnaire's disease-- is most common in middle-aged and elderly people, smokers, and those with chronic illnesses such as heart disease and COPD or a weakened immune systems. People with Legionnaire's disease MAY also experience diarrhea and a cough that produces bloody mucus. These symptoms may worsen in the first 4-6 days and then improve over the next 4-5 days. On rare occasions Legionnaire's disease CAN cause kidney damage, the onset of COPD, diabetes and more. If your walking pneumonia treatment involves a course of antibiotics, make absolutely sure to FINISH your entire prescription even if you're feeling better-otherwise, your symptoms may return even stronger. Whether you feel like it or not, drink plenty of fluids and GET REST. Your doctor may allow you to treat your fever--and any aches and pains-- with over-the-counter medicines such as aspirin or acetaminophen. And remember, although walking pneumonia IS milder than other forms of the infection, you should still see your doctor for proper diagnosis and treatment.

Acute bronchitis heralds its arrival with MISERABLE symptoms such as constant, wet coughing, wheezing, sore throat, low fever, fatigue and chest pain.Since these symptoms are most often caused by a VIRAL infection, you can't relieve them with antibiotics. But good home care can often relieve your acute bronchitis symptoms. Start by looking for something warm and wet. You can turn on a humidifier or vaporizer to breathe humidified air. If you don't have one, STEAM from a hot shower will do the trick. The hot air will loosen up the mucus lining your lung's airways, making it easier to cough out. You can also eat chicken soup! Besides loosening your mucus, it has the added benefit of soothing your raw throat. Another tip is to drink PLENTY of fluids, especially hot tea. Like chicken soup, they will also loosen mucus. To relieve chest pain, body aches and fever, you CAN take acetaminophen, available over-the-counter. If you happen to be a smoker, STOP! Smoking inhibits your recovery from acute bronchitis because it LIMITS your lung's ability to clean out foreign particles and mucus. If you quit, you'll feel SIGNIFICANTLY better. Finally, it's important to get REST. Get into bed, and stay there longer than usual. You need energy to combat the infection that's attacking your lungs. Acute bronchitis is a SELF-LIMITING condition, which means it'll eventually go away on its own. Almost all symptoms should dissipate after a few days to 2 weeks, but your cough can linger for up to 2 months.

Most of us inhale and exhale without thinking. But, people with bronchitis often have a HARD time simply breathing. Bronchitis occurs when the lungs' airways-called bronchial tubes -- become inflamed, SWOLLEN and lined with MUCUS. ACUTE bronchitis and CHRONIC bronchitis have similar symptoms - they include incessant coughing that produces PHLEGM, wheezing, chest pain, fatigue, low fever, body aches, mild headaches and sometimes, shortness of breath. And, both conditions are MUCH more common in SMOKERS, so quitting is KEY to prevention. Even people who are regularly exposed to secondhand smoke are more susceptible to these diseases.ACUTE bronchitis- informally known as a chest cold-- occurs after a cold or flu. The viruses-and rarely bacteria-that cause these infections SPREAD into the lungs and trigger inflammation, swelling and mucus. Since most cases of acute bronchitis are VIRAL, antibiotics WON'T help. Instead, your doctor will recommend rest, fluids, over-the-counter pain relievers, and humidifier use. You MAY need medicine to open up your airways if you're wheezing. Most of your acute bronchitis symptoms will go away after a few days to 2 weeks, but the phlegmy COUGH can last up to 2 months. CHRONIC bronchitis is a LONG term condition that is caused 90 PERCENT of the time by - what else? -- CIGARETTE smoking. You don't need to catch an infection to develop it - chemical irritants in smoke, as well as smog or work-related air pollution-think about coal miners and textile workers-can damage the airways.You will be diagnosed with chronic bronchitis if you have a mucus-y cough most days for 3 months a year -- for 2 consecutive years. The onset is gradual, but it gets worse if you don't quit smoking. And for anyone with chronic bronchitis, getting a cold or the flu makes it even worse. To treat chronic bronchitis, doctors focus on easing symptoms. There is no cure. Patients may use inhalers, such as bronchodilators, to open up their bronchial tubes. In severe cases, they may require supplemental oxygen therapy. Generally, people with chronic bronchitis should also rest, drink plenty of fluids and use humidifiers. OVER TIME, people with bronchitis also develop EMPHYSEMA-the gradual destruction of the lung's air sacs. Together these two conditions are called Chronic Obstructive Pulmonary Disease, or COPD, the THIRD leading cause of death in the United States. I'll reiterate one more time - if you quit smoking, you'll REDUCE your chances of developing acute AND chronic bronchitis. And it's never too LATE to quit--people who already have these conditions feel better if they stop smoking.

Pneumonia is a lung infection that needs proper care. But knowing pneumonia treatment & prevention can be helpful in avoiding it. Watch the video to know more.

Pneumonia is an inflammation of the lungs. It can be caused by a bacterial or viral infection. And it's NOT an infection you can recover from in a day or two. So it's smart to try your best to PREVENT this disease. All infants 2 months and older and children up to age 18 should be vaccinated against BACTERIAL pneumonia - the cause of about 50% of all cases. The vaccine should also be given to all adults 65 and older. People between the ages of 18 and 65 may need the vaccination if they have a chronic illness. Ask your doctor what is best for you and your children. There are two types of vaccines: pneumococcal conjugate vaccine or PCV13 and pneumococcal polysaccharide vaccine - often called PPSV. The vaccines protect against anywhere from 13 to 23 different strains of the disease. This isn't every type of bacterial pneumonia-but it's enough to provide pretty good protection for most people.VIRAL pneumonia, on the other hand, most often develops as a result of having the FLU. So for prevention it's also smart to get an annual flu vaccine. Other ways to avoid BOTH types of pneumonia include:eating a nutritious diet, getting plenty of exercise, having good sleep habits, never smoking, and washing your hands OFTEN. Still, many people come down with pneumonia despite their best efforts. Fortunately, in most cases, pneumonia treatment is fairly straightforward. BACTERIAL pneumonia is usually treated with a course of antibiotics. You should always continue taking the medication to the end of the prescribed regimen, even if you're feeling better. Otherwise, the illness may return with greater strength. Most of the time, patients can recover at home with plenty of rest, fluid intake, and sometimes over-the-counter pain relievers and fever reducers. VIRAL pneumonia won't respond to antibiotics. A doctor may prescribe anti-viral medication, but in most cases this type of pneumonia will run its course after 1 to 3 weeks. Rest, fluids, pain relievers and fever reducers are the best bet. During treatment you can improve breathing and loosen mucus by using rhythmic breathing and inhaling steam. Try running a hot shower and sit in the room as it fogs up. Pneumonia patients who are elderly or have other illnesses such as cancer or heart disease should head to the HOSPITAL for treatment, particularly if they have fast breathing, a rapid heartbeat, low blood pressure, a fever above 104, or an altered mental state. A hospital visit is also necessary for children and infants who struggle with breathing and run high fevers. To learn more about pneumonia, take a look at other videos in this series.More »

Cough suppressants and expectorants are supposed to help relieve severe cough -- watch this video to learn if they are truly effective.
Transcript: Cough SUPPRESSANTS and cough EXPECTORANTS are both helpful medications, but each one is made to be used...
Cough SUPPRESSANTS and cough EXPECTORANTS are both helpful medications, but each one is made to be used for a different TYPE of cough. It's important to note that neither suppressants nor expectorants will TREAT what ails you, but it's possible they could help relieve your symptoms. The active ingredient in most over-the-counter cough SUPPRESSANTS is called dextromethorphan. It keeps you from coughing by repressing the cough REFLEX. Dextromethorphan should never be given to children under the age of 4 and NEVER give a child a cough suppressant made for adults. You can take cough suppressants IF your cough is DRY, meaning it doesn't produce mucus. Causes of dry cough include allergies,, ,viral infections, gastroesophageal reflux disease, and exposure to dust or environmental pollutants. You should NOT take cough suppressants if you have a WET, or PRODUCTIVE, cough, meaning that you cough up mucus and phlegm. Even though coughing is a hugely annoying -even painful-- symptom, you want to KEEP ON doing it in order to get rid of the mucus that's lining your airways. Causes of WET cough include acute and chronic bronchitis, asthma, pneumonia, colds, and flu. You can take cough EXPECTORANTS for these conditions. The main ingredient in expectorants is GUIAIFENISIN. This drug thins the mucus, making it easier to cough up. It should be noted that many doctors and experts--including those from the American College of Chest Physicians-- DON'T believe that cough suppressants or cough expectorants are effective for most people. But people do occasionally find them helpful, so they may be worth a try. If you have a cold or the flu, and these drugs DON'T have an effect on your dry or wet cough, try a decongestant. HOME remedies for soothing a cough include eating chicken soup and drinking plenty of fluids, especially hot ones, and steaming yourself in the mist from a hot shower or with your head covered over a pan of hot water. If your cough is a symptom of a serious respiratory condition such as chronic bronchitis, COPD or asthma, you'll need to see a doctor. Additionally, if your cough has persisted for 3 or more weeks, you should also see your doctor.More »

Coughing-it's a symptom that people with acute AND chronic bronchitis know all too well. Acute and chronic bronchitis happen when the airways in your lungs become inflamed, swollen and lined with mucus. The coughing is your body's attempt to rid itself of the mucus and open up those air passages once again. Other symptoms that acute and chronic bronchitis share are wheezing, fatigue, chest pain, slight fever, and body aches. People with chronic bronchitis may also experience swelling of the legs, ankles or feet, and shortness of breath. The conditions DO DIFFER dramatically in their TRIGGERS, DURATION, TREATMENT and possible COMPLICATIONS.ACUTE bronchitis begins when a virus -or, rarely, a bacteria -- that causes a cold or flu TRAVELS to the lungs from your nose and sinuses. It occurs more often in smokers, those exposed to secondhand smoke, and people who work with lung irritants such as chemicals and fumes...but it can also happen to people with chronic sinus infections and allergies. Acute bronchitis patients can't do much to TREAT their disease except rest, drink plenty of fluids, breathe in HUMIDIFIED air, take over-the-counter pain relievers and occasionally use an inhaler to open up their lung's airways. The viral infection cannot be treated with antibiotics. Acute bronchitis can go away in a few days to a couple weeks, but the persistent cough may last up to 2 months. CHRONIC bronchitis is a more serious condition. Defined as having a cough MOST days for 3 MONTHS a year for 2 years in a row, it's no surprise that it's caused by cigarette smoking 90 PERCENT of the time. Chronic bronchitis develops gradually, but it worsens after a cold or flu. In fact, sometimes a person has to cope with chronic AND acute bronchitis at the same time. Treating severe chronic bronchitis often involves inhaled medicine to help relieve shortness of breath and WHEEZING, OXYGEN therapy, and SOMETIMES pulmonary rehabilitation, which is a program that teaches you how to breathe more easily.While coughing up mucus doesn't SEEM life-threatening, OVER TIME chronic bronchitis can cause serious lung damage. It's one of two conditions that make up chronic obstructive pulmonary disease, which is the third leading cause of death in the U.S. To learn more about bronchitis and COPD, watch other videos in this series.More »
