chronic cough

[Jenn869]

For the past 3 years I've had a cough that will not go away. I saw my doctor, and was tested positive for asthma. I was prescribed Advair and a rescue inhaler. None of it worked. I coughed all day long until I vomited. Mainly when I cough I produce large amounts of mucus. I went to another doctor after my previous doctor relocated. The new doctor agreed that I had asthma and prescribed Singular and Symbicort. Again, I saw no results but my doctor insisted that I stayed with the treatment. After I year, I moved to Japan and was still using Symbicort and Singular with no affect on my cough. I started seeing a new doctor who told me that I had walking pneumonia. He prescribed a large round of anitboitics. Little has changed. I still have coughing attacks anytime I do anything physical (walking up stairs, riding a bike, waking up in the morning, etc.). I've been coughing for 3 years and nothing has changed. I need to be cured of this cough because I can't go on like this for another year.

I've been on Spiriva for the past week. There has been some improvement but I still wake up in the morning coughing, and I still have coughing spells that result in vomiting mucus. My doctor told me I have mild COPD. I'm 25 years old and never smoked a day in my life. I'm going to see a pulmonary doctor for a second opinion.

Sublingual (under the tongue) vitamin B12 - 1000mcg daily is highly recommended for see if this improves your chronic unexplained cough. I use sublingual spray which i prefer; no waiting for the sublingual tablet to dissolve.  

Try 2000 IU vitamin D3 daily for asthma and mucus build up.  If i forget to take my vitamin D3 supplement, i find myself clearing my throat due to excess phlegm.

"The Scientific Study

Background information
The relationship between vitamin B12 and unexplained chronic cough was assessed in 40 study participants with unexplained chronic cough. Participants were evaluated with spirometry and nitric oxide levels were measured. Histamine inhalation was used to evaluate the bronchial, extrathoracic airway and cough thresholds. The study aimed at testing the hypothesis that vitamin B12 deficiency causes unexplained chronic cough via sensory neuropathy.

Results
25 out of the 40 participants with unexplained chronic cough were vitamin B12 deficient and all had higher levels of nerve growth factor (NGF) in epithelial cells than non-deficient patients. Elevated NGF levels increase neurogenic (nervous tissue) inflammation of the airway, which interrupts the passage of air and causes coughing. The study results indicate that vitamin B12 deficiency causes neurogenic inflammation of the airway, wihch in turn leads to chronic cough. Patients deficient in vitamin B12 also had lower extrathoracic airway, histamine and cough thresholds.

Results
Vitamin B12 supplementation improved histamine thresholds with improvement in bronchial (p<0.01), extrathoracic airway (p<0.001) and cough (p<0.01) thresholds."


"In the last twelve months, multiple studies have shown a connection between Vitamin D and asthma. Initially, studies demonstrated that Vitamin D deficiency may be a significant causative factor in the development of the condition. More recently, clinical trials have shown that those with higher Vitamin D levels show an improved patients response to standard asthma treatments and Vitamin D supplements significantly reduce the number and severity of asthmatic attacks in children."
