Apart from the pretty constant sore throat, as well as other throat sensations including hoarseness, my sinuses and ears were not good at all.
I had not, at that stage, related my throat clearing, mucous build up and Post Nasal Drip to all be part of typical LPR symptoms. I was fairly ignorant of how LPR can present and the symptoms that go with it.
I now understand why it is termed a multifactorial condition and whilst it can be typically diagnosed by an ENT it's management can be most difficult.
Traditional reflux treatments can be somewhat inadequate.
I did read about a couple of drugs trials which didn't work out that well to try and limit the refluxing of Pepsin. It doesn't have to be in a liquid form but a gas or aerosol burped up into your airways.
As well as LPR impacting in my sinuses, and ears, there were noted structural issues with my maxillary, frontal and ethmoid sinuses which required two FESS operations to correct.
Diet and lifestyle including anxiety and stress plays, imo and from what I have read, a very big part in the management of LPR.
I have used with some success high alkaline water, above 9 in the scale. That helps to deactivate and destroy the Pepsin that it would comet into contact with. Of course as pepsin continues to be deposited then that process is ongoing.
I also irrigated several times a day using a more alkaline mix. Sometimes I would also use a facial steam machine with alkaline water to breathe that into my airways.
But, for me, the irritating cough was fairly minimal, others are more impacted with their airways and lungs.
High alkaline water can be bought, made with a filter type jug or, less ideal, made by using sodium Bicarbonate in water. The latter isn't much use for people with high BP as it contains lots of salt.
The other symptoms that you note, digestive disturbances and gases etc... Remember that LPR is multifactorial and presents with a wide range of symptoms.
I knew one person who has LPR and she told me that her specialist related it to IBS of the upper digestive tract to what the more typical IBS is of the lower digestive tract.
