Hi Dr. Saha,
She has had the condition for a long time and it occurs towards the end of the year for at least 3 months due to weather changes. It is like a chronic and constant cough during that time. There is only coughing and the vomiting is only recent and does not usually happen.
Apparently, she has been investigated and there is a name for the condition. I will get back to you with the name tomorrow. Sorry she's not been completely clear or detailed about her condition.
I have been able to find out that the white matter is simply sputum and that the condition is thought to be allergic cough to unknown allergens. It was just surprising, though, that the white matter could be found in the vomit and could cause vomiting.
Would you agree with such an assessment, considering coughing at certain times of the time only?
Thanks for the information Dr. Saha. She also mentioned that it is a form of asthma but not quite as serious. I though it might be asthma caused by allergic reaction but there is no typical wheezing or shortness of breath. I think the condition has probably been hard to know exactly but some inflammation of the lungs is involved.
