Flu

Flu - Animation

Your head is throbbing. Your throat is burning. You're coughing nonstop, and your whole body aches. This is no run-of-the-mill cold. You may have the flu. Let's talk about influenza, also known as the flu. Winter is a time for sledding, snowball fights, and flu. Every winter, millions of Americans come down with this respiratory ailment and feel absolutely miserable. Like the common cold, the flu is caused by a virus. But with the flu, it's the influenza virus that makes people so sick. The flu virus comes in a few different forms. Influenza A is most common between early winter and spring. You can catch influenza B year-round. Swine flu, or H1N1, is a specific type of influenza A. You catch the flu from someone who has it. When people with the flu sneeze or cough, they send a spray of droplets filled with the flu virus into the air. If you're unlucky enough to be nearby, you could breathe in those droplets. Or, you might touch a surface that the droplets have fallen on and then touch your nose or mouth. Two to three days later, the first flu symptoms will appear. Usually you'll start running a fever. Then you'll feel achy and tired. You may have the chills and feel sick to your stomach. After a couple of days, the sore throat and cough will set in. So, how do doctors treat the flu?Because a virus causes the flu, antibiotics won't treat it, they only kill bacteria. There are antiviral medicines, but you need to start taking them within the first 2 days after your symptoms appear. Until the illness runs its course, help yourself feel better by getting a lot of rest and drinking extra fluids. You can take an over-the-counter cold medicine to relieve your congestion and cough. Tylenol, Advil, or Motrin can bring down your fever and take some of the pain out of your sore throat. Aspirin isn't recommended during the flu, especially under age 18, because it could increase the risk for a rare, but serious, condition called Reye syndrome. By itself, the flu usually isn't harmful. But it can make existing conditions like asthma and breathing problems worse. In older people or those with a weakened immune system, the flu can turn into pneumonia, bronchitis, and other more serious diseases. For most healthy people, the flu is a short-term annoyance. They're stuck in bed for a week or two, and then their symptoms go away and they're back up and around. But thousands of people each year get very sick from the flu, especially the elderly, young children, and pregnant women. Many are hospitalized, and about 36,000 people die from flu complications. To avoid getting the flu, eat well, get plenty of exercise and sleep, and practice good hygiene. Wash your hands often with warm water and soap or use an alcohol-based hand sanitizer. Don't share cups, plates, or utensils, especially during flu season. And most effective, get your flu shot every fall to protect you through the whole flu season.

Tips on buying cold and flu medicines - Animation

They call it the common cold for a reason. Colds are extraordinarily common. Children average 3 to 8 colds a year and adults almost that many. I'm doctor Alan Greene and I want to give you a couple of tips about navigating the cold and flu aisle at the drug store. Many of the offerings that are there will offer relief in several different ways. They may have a decongestant in there to try to reduce nasal congestion. An antihistamine that may help a bit with sleep or may also help with some congestion. They may have a cough suppressant in there to make you cough less. An expectorant to make your cough more productive, so you can cough things out easier and may have something to bring down a temperature or relieve aches and pains, like acetaminophen, or ibuprofen. But if you pick-up more than one of these, it's pretty common for people to double-up on a specific ingredient. So, if you're using more than one, look at the ingredient list. You don't want to see the same thing on both. For instance, if you have the decongestant pseudoephedrine on two different lists, the double-dose is not good for you and doesn't add any extra help. But beyond that, you don't even want to find the same action in two different multisymptom things. So if you have been taking a decongestant, you don't want a decongestant in the other one, whatever kind of decongestant it is. And as a reminder for kids under 6, decongestants, antihistamines, and cough suppressants have not been shown to help them any better than placebo and do have some side-effects. So, I don't recommend them at all for kids under 6.

The difference between a cold and the flu - Animation

So what's the difference between cold and flu. The two words go together like salt and pepper or like New Year's and weight loss. I'm Dr. Alan Greene and I want to help you figure out what the difference is. Most people have a general idea that they are different, but when pressed have a hard time really saying what the difference is. The cold, the common cold, is something very common you usually get on average 3 or more times during a year. And it is a virus that's primarily in the nose. The cold is focused in the nose. The 3 main symptoms of a cold are sneezing, nasal stuffiness, and runny nose. All are focused in the nose. You may have other symptoms - you may have a fever of 100°, 101°, maybe you may have some tickling or scratchiness in the back of the throat. In fact, that may be the very first symptom - a little scratch in the back of the throat. Then after a couple days the nasal discharge tends to turn a little bit darker, greener. And then after about a week you're all the way better. But it's focused in the head, focused in the nose. With the flu you're sick all over. It's a whole body disease. It's a much more serious illness. The flu in the United States today still kills about 36,000 people a year. Mostly people who already are weak for some reason or another. But it's a serious illness. And it usually slams into you with a fever. Typically the fever is in the 102° all the way up to a 106° range. A higher fever often the first symptom and you feel sick all over. You have muscle aches, you're tired, you feel out of it, you really feel crummy. And after a couple of days the respiratory symptoms start to come too. And depending where the flu virus settles you might have some sneezing, you might have some coughing. The classic symptom is a dry, hacking kind of cough, could be wheezing, could be other things, but the cough is the most common. Then it's there also for around 7 days or so and then at the end of it you may have another peak of fatigue and a second peak of fever. But usually after about a week you'll start feeling better with most cases of the flu. Colds and flus are very, very different illnesses with a few of the same symptoms.
