Causes, Treatment and Complications of Asthma

Treatments Asthma is usually treated by using an inhaler, a small device that lets you breathe in medicines. The main types are: reliever inhalers – used when needed to quickly relieve asthma symptoms for a short time preventer inhalers – used every day to prevent asthma symptoms occurring Some people also need to take tablets. Read more about how asthma is treated and living with asthma. Causes and triggers Asthma is caused by swelling (inflammation) of the breathing tubes that carry air in and out of the lungs. This makes the tubes highly sensitive, so they temporarily narrow. It may occur randomly or after exposure to a trigger. Common asthma triggers include: allergies – to house dust mites, animal fur or pollen, for example smoke, pollution and cold air exercise infections like colds or flu Identifying and avoiding your asthma triggers can help you keep your symptoms under control. Read more about the causes of asthma. How long does it last? Asthma is a long-term condition for many people, particularly if it first develops when you're an adult. In children, it sometimes disappears or improves during the teenage years, but it can come back later in life. The symptoms can usually be controlled with treatment. Most people will have normal, active lives, although some with more severe asthma may have ongoing problems. Complications Although asthma can normally be kept under control, it's still a serious condition that can cause a number of problems. This is why it's so important to follow your treatment plan and not ignore your symptoms if they're getting worse. Badly controlled asthma can cause problems such as: feeling tired all the time underperformance at or absence from work or school stress, anxiety or depression disruption of your work and leisure because of unplanned visits to your GP or hospital lung infections (pneumonia) delays in growth or puberty in children There's also a risk of severe asthma attacks, which can be life-threatening.

PF-ROM Exercises

"Pain-free range of motion’ or early mobilization exercises can help you heal" PF-ROM is physical therapy talk for “pain free range of motion.” When a therapist evaluates an injury, he or she will be interested to see how far you can move affected joints without hurting. Sometimes, of course, you can’t move at all without pain. But in most injuries, even many serious ones, you will have at least some painless movement. And whatever you’ve got, you should use. When you are hurt, the pain-free range is your new best friend: that’s the range you’ll be exercising in for a while. Pain free range of motion exercises are also known as “early mobilization.” Use it or lose it “Use it or lose it,” they say. And it’s true. While many seemingly simple medical questions are controversial, this one appears to be straightforward: plenty of recent research demonstrates that early mobilization is A Very Good Thing. A 2006 study of people with surgically repaired achilles tendon ruptures sh...

A Short Story

A silent, anonymous place I was still a child the last time I’d seen it. The hospital was an anonymous place my parents had taken me to, somewhere in the big city, far from home. I didn’t know where I was at the time, but when I saw it again as an adult, there was a match with something stored in my skull: the outline of the building like a stack of building blocks, the primary colours, the silence that seems out of place around a place built for children. Medical science failed me in that hospital. I was diagnosed early with “slow growth syndrome,” and this was the first mistake that science made with me: giving it a name. Slow growth syndrome is no syndrome at all. Some people grow slowly. So what? I was small for my age. I didn’t have a pathology: I had a velocity. I was taking my time. Nevertheless, the doctor wanted to keep an eye on me, so my parents dutifully took me back every two years to be measured and the pace of my growth evaluated for more distressing signs of oddity. I...

Don’t waste your money on expensive trainers

Expensive running shoes offer no benefit in terms of cushioning impact and overall comfort compared with 'cheap' trainers, reported The Times and other newspapers on October 11 2007. The researchers found that “no amount of built-in air bubbles, shock absorbers or other cushioning makes a difference to the overall pressure on the foot.” The stories are based on a study that compared the performance of low-, medium-, and high-priced running shoes in men while they were walking, and in a smaller group who ran. The interpretation by the newspapers that this study has shown that expensive trainers do not protect runners’ feet is not quite accurate as the “running” part of the experiment was small and the researchers themselves state that “it was not possible to reliably detect differences between pressure in shoes from different brands and across cost ranges”. Importantly, the participants in the study were normal runners. They didn’t have any gait abnormalities such as over or ...
