Asthma

Definition

Asthma is a condition which is created by the production of thick sticky mucus in the airway, compounded by spasm in the smaller airways.

Asthma represents a condition in which several problems overlap. One of the early symptoms of asthma is a dry cough, often worse at night. As the condition worsens, it usually proceeds to a wheeze, starting on the out-breath, but as is worsens, on the out and in-breath.

These problems may be grouped in three categories:

Allergic

In asthma the white blood cells, other cells, and chemical substances in the airway wall are primed to over-react to allergens (animal dander, dusts, dust mite fecal matter, pollens etc.) or chemicals (perfumes, smog, vehicle exhausts, cigarette smoke,) or food triggers (dairy products, peanuts, shellfish etc.).

Hyper-reactive airwaysRespiratory tree

This sensitive condition relates to allergies and is made worse as the muscle fibres in the medium and small airways (illustrated to the right) get more 'practice' in tightening up. These constrictive muscles are what, in health, help to protect our lungs from pollutants in the air. With asthma, the muscle bands around the airways get thicker. The muscle bands are illustrated by the pink fibres in this illustration.

This condition is accentuated by an imbalance in the fatty acid composition in the diet - too much Omega-6 and Omega-9 fatty acids. These substances are found in oils from corn, canola, soy, safflower and to a much lesser extent in flax. Commercially prepared packaged and fast foods are prepared using these oils because they can easily be purified i.e. stripped of their components which render them susceptible to rancidity, and which allow them to be heated to high temperatures without readily breaking down.

A diet with some of these oils is not harmful, but if the majority of the diet comes from such food, it creates an imbalance. The consequence of this imbalance is the tendency of the body to contract, to become inflamed, irritated.

To be healthy, we require a diet balanced by oils containing Omega-3 fatty acids. Omega-3 fatty acids are found in fish, flax, borage and evening primrose oils and some of the foods upon which fish feed - plankton, and blue green algae. Increasing the proportion of Omega-3 to Omega-6 and Omega-9 oils can help the airways relax and improve asthma symptoms.

Unfortunately, most of the commercially available fast foods are prepared with the problem oils, canola, safflower etc., so it takes some effort to shift the diet away from these foods.

Thickened mucus

Mucus becomes thicker in dry air, (winter heated air), with inadequate consumption of water, and in my experience, with excess dairy and flour consumption, and with insufficient vegetable foods in the diet.

How does Asthma start?expectant

Often the roots of asthma can be traced to the medical condition of the parents. Sometimes it's that they were allergic, or that they had asthma or eczema. The mother may report that she had some digestive difficulty with milk or dairy products during her pregnancy.

Some children get asthma with the introduction of cow's milk-based formulas. This is often accompanied by colic, heralding a digestive connection. Often the first asthma attack comes some time after a course of antibiotics. The connection in this case is likely that antibiotics can create a candida overgrowth in the digestive system, a condition called leaky gut, which, in my experience can lead to asthma. In children, acute ear infections, often following a viral upper respiratory infection, are a common reason for an antibiotic

My interpretation of these connections is that the digestive system of the affected children becomes injured in one, or several, ways leading to a condition referred to as 'leaky gut'. In this situation Candida is a common culprit. In leaky gut, proteins, often those from cow's milk, leak through the small intestine wall setting up a hyper-reactive response which seems to effect the lung as well as the intestine.

Breast fed infants seem less likely to have this reaction unless the mother is eating a lot of dairy and she can't fully digest it, or perhaps she is eating foods to which she is sensitive.

Antibiotics, while very helpful for bacterial ear (and other) infections, can strip the intestine of beneficial bacteria and leave it vulnerable to leaky gut. Dairy, wheat, and to some extent, baked flour products, may in my experience, also contribute to increased respiratory mucus. This mucus affects the eustachian tubes, the passages leading from the mouth to the middle ear and when these tubes become loaded with mucus, they provide fertile territory for infections.

What do drugs do for Asthma?

Bronchodilators puffer

These medications, like Ventolin®, cause the smooth muscle in the airway walls to relax. They work quickly and provoke the same kind of response as when we undertake strenuous exercise in which we produce adrenalin, which also opens the airways. Well known side effects include the 'jitters' and an increased heart rate. There are also a group of longer acting bronchodilators.

Steroids

These may come as a spray which is inhaled, as a powder which is sucked into the lungs. They can also be given orally or injected. Steroids reduce inflammation. They don't act quickly but when used regularly, usually twice daily, can have a very beneficial effect on asthma symptoms. The downside is that they encourage yeast infections - (thrush caused by Candida).

Immune Modifiers

These medications like Singulair™ reduce the way certain white blood cells, mast cells and eosinophils respond to allergens like pollens and animal dander. They can be quite helpful for some people.

What do I usually Recommend?

Often as you begin the process of healing your asthma, you will need to use your puffers or other medication. As you improve, with the permission of your doctor, you will likely be able to reduce the frequency of use of your puffers, and in some cases, be able to stop them. Some people need them only briefly when they have a viral upper respiratory infection.

You may find that, over time, you can identify triggers which you may be able to avoid. Some people find that allergy injections, prepared by an allergist, may help. During, or following a cold or flu, there may be a temporary worsening of symptoms which may require a brief return to medications.
