Asthma Treatment and Diagnosis




Asthma Treatment and Diagnosis

By Richard Robertson

If you ever met anyone with asthma, an attack usually encompass a shortness of breath that soon passes without treatment. But it can also be a very life threatening event that can end up putting the sufferer in an emergency room. An average of 5,000 asthma deaths are reported in the United States each year. Most of the deaths occurred in patients who misjudged the severity of their symptoms or failed to reach a hospital or clinic in time to prevent death.

Diagnosing Asthma

Asthma diagnosis is based on repeated, careful measurements of how efficiently the patient can force air out of the lungs and on a thorough medical history and laboratory tests to find out what triggers the patient's acute attacks.

People with asthma react to external irritants in a way that non-asthmatics don't. Many, but not all, sufferers have allergies that cause their bodies to produce an abnormal array of chemicals in response to environmental allergens. In that sense, asthma is like pollen allergies, hives, and eczema. But in asthma, the allergic reaction contributes to inflammation of the airways rather than of skin, eyes, or nose and throat. An acute asthma attack may come on rapidly after exposure to an irritant or develop slowly over several days or weeks, which can complicate the job of identifying a patient's asthma triggers.

Which drugs asthma patients need, when to use them, and how much to use depend largely on the character of their illness, as shown by the degree of breathing impairment and the frequency and severity of acute attacks. Many doctors and researchers agree that the first line of defense is avoidance of whatever brings on an acute asthma episode. In some asthmatics, attacks can be brought on by strenuous exercise, exposure to cold outdoor air, industrial or household chemicals and food additives such as sulfites. Influenza or even cold viruses can also trigger asthma episodes. There are many cases where triggers cannot be identified, even after a thorough investigation.

Asthma Treatment

Knowing what provokes an asthma attack is critically important in prevention, but it's often difficult or impractical to avoid contact with triggering irritants. Today, however, doctors can prescribe drugs to lessen the risk of acute attacks after exposure to an offending irritant, as well as halt attacks that can't be prevented.

The drugs used to treat asthma fall into two broad categories: controllers to prevent acute attacks and relievers that check acute symptoms when they occur. Some drugs do both.

In light of mounting evidence that asthma is fundamentally an inflammatory disease, asthma authorities today regard inhaled corticosteroids--marketed under numerous brand names as the most effective agents for controlling airway inflammation and thus preventing acute asthma attacks. Corticosteroids in pill or tablet form and in liquid form for children are prescribed long-term for some patients with severe asthma, or short-term for patients with a serious asthma episode.

Bronchodilators work to help open the breathing tubes (bronchi), but do not treat the underlying inflammation. There are both short-acting and long-acting bronchodilators. Long-acting inhaled bronchodilators, and long-acting oral bronchodilators, are often used in conjunction with anti-inflammatory agents to control symptoms. They don't provide immediate relief of symptoms, but their preventive action persists for many hours, which makes them useful in controlling attacks that might occur during hours of sleep.

Drugs to bring quick relief in acute asthma attacks are chiefly short-acting inhaled bronchodilators that act rapidly but for a relatively brief time to relax bronchial constriction. Although these drugs are effective in treating asthma, there is some controversy about their safety, especially when they are overused. Scientific debate makes it clear, however, that an increasing need for inhaled bronchodilators, or a decreasing response to each dose, is a signal that the patient's asthma is not being adequately controlled. Patients who have an increasing need for short-acting inhaled bronchodilators should be re-evaluated promptly by their physicians.

Both prescription and over-the-counter short-acting bronchodilators are available. Like the prescription drugs, the OTC drugs act only to provide symptom and relief, and they are generally effective for a shorter period. They may be useful, therefore, as temporary treatment for mild asthma attacks. Ready availability in drugstores makes the OTC products potentially helpful as a "stopgap" for patients who do not have their prescription medication at hand when an asthma attack occurs. More importantly, patients who use OTC inhalers should still seek advice from a health professional about the long-term treatment of their asthma.

The key to effective, long-term treatment of asthma is finding the drugs and dosage plan most effective in dealing with or preventing acute episodes. But effective treatment depends as well on the patient and the care-giver knowing what the various anti-asthma drugs do, when and in what amount each drug should be used, when a change in symptoms or in the response to a particular drug requires a call or visit to the physician, and when to get emergency help. Physicians who specialize in treating asthmatics go over these points in detail as part of an overall treatment plan designed and, as necessary, adjusted to meet the needs of each individual patient.

A cure for asthma is judged by experts to be still a far-off possibility. But the majority of asthma sufferers can lead essentially normal, symptom-free lives by understanding and sticking to a well-planned strategy to keep clear of asthma triggers and to use the right drugs in the right way.

Top Five Foot Heel Pain Remedies



Top Five Foot Heel Pain Remedies

By Dave Wilson


Years of walking and running can wear down our feet, and can be hard on our heels. Likewise, poor circulation, improperly trimmed toenails, disease and tight fitting shoes all contribute to pain in the heel.

1. Massage with water

This treatment is ideal for any type of foot or heel pain and only needs a container of hot and cold water. Here's what you do:

a. Soak your foot for 5 minutes in cold water

b. Move the foot to a container of hot water of a tolerable temperature. The temperature of the water should not be cool or even lukewarm

c. Soak the foot in the hot water for 5 minutes

d. Return to the cold water

Repeat the procedure until the pain is gone. This process has a massaging effect that revitalizes feet by opening and closing blood vessels.

It is also a great idea to rub moisturizing lotion into your feet before getting into bed. The lotion makes feet easier to massage and therefore bring relief faster.

2. Put some heat on your feet

Using ointments enriched with capsaicin, an active natural ingredient in hot peppers also helps in relieving foot pain.

These products are excellent in cooling the pain caused by burning feet particularly for diabetes patients. Initial application of the ointment may cause some burning sensation for many people, but when used regularly, the burning effect is likely to lessen.

Moreover, people who been using the capsaicin in treating their burning feet have experienced great improvement and were able to walk more easily compared to those using other types of creams. Best of all, since these are topical medicine, patients tend to avoid a lot of side effects that usually happen when taking pills.

Most ointments are available over the counter, however it is important to talk with your doctor before you begin, as this type of therapy is not right for everyone.

3. Avoid high-heeled shoes

For recreational walkers and runners it is important to temporarily lower how much you're walking or running when you're about to use brand new shoes. This will help you to eliminate many of the break-in pains. Advances in shoe development have made modern athletic footwear much less likely to cause a problem than ever before.

4. Stretch out your calf

Stretching the heel cord at the back of the foot can relieve heel pain.

Start by:

a. Standing three feet away from a wall, place your hand on the wall.

b. Lean in to the wall, bringing one leg forward and bending at the elbows.

c. Keep your back leg straight with the heel on the floor and then gently stretch the calf muscle.

d. Repeat for the other foot.

e. Buy shoes that fit the shape of your feet.

Shoe size is considered to be the most important aspect in buying shoes -- but the shoe shape is equally important. You read it right; the shape of the shoe is also an important factor to consider.

There three basic foot shapes -- curved, slightly curved and straight. Although, there may be some variations, generally those individuals with high arches need a curved shoe; those with flat feet need a straight shoe and those who have neither flat or high arches need a slight curve.

When buying running or walking shoes it is best to select shapes that fit the curve of the arch on the inner side of the foot.
Before you try any of the remedies discussed here, consult your own doctor for the treatments that will be best for your unique situation.
