It's all about control.
I'm weeks from 79 years of age and 20 years of COPD. I know the insides of ERs (A & E to Brits) and innumerable exacerbations with the attendant antibiotics and steroids at almost monthly intervals. That was until 30 months ago.
My new view
I took the view that our bodies WERE supplied with immune systems so lets get them working on this problem (It was only a week ago I learned that antibiotics and steroids are seriously not good for the bacteria which run out immune system).
A search of the internet found a US collection of cheap common supermarket products which boost the immune system which I take every morning for those 30 months. Far more recently I have changed my diet a smidgen towards green veg and away from highly processed foods and also started taking a probiotic.
What helps my symptoms
The original formula (I take only 50% of each item) is 2 tablespoons of each of honey, lemon juice and apple cider vinegar plus some hot water. The 4th element, a teaspoon of cinnamon powder I add to the breakfast cereal. In each case I avoid the more expensive brands - honey is honey no matter where it comes from.
This is NOT a cure but it helps control the symptoms - I have gone back to the gym daily, dig the garden and generally live an active life which I could not do 3 years ago. I still take the prescribed medicines.
For more info check "microbiome" on google; it is a very young branch of medicine but will help explain how the immune and other body systems work and fail.
