How Can Foaming That Regurgitates To The Throat Be Diagnosed And Treated?
PH monitoring of the esophagus might be recommended to confirm diagnosis
It seems very likely your husband is having gastroesophageal reflux disease or the so called GERD.
This is mostly suspected if the patient has content coming back from his stomach to his mouth. Endoscopy might notice redness of the esophagus but most of the time is not diagnostic for GERD. If clinically we suspect GERD but is not diagnosed or the patient is not responding to treatment then it is recommended to have PH monitoring with ambulatory esophageal reflux monitoring- this is the most accurate test to relate symptoms with GERD.
I would recommend you to talk with your doctor on the possibility of having this test as it is recommended for presumed GERD cases that are resistant to treatement with PPI (nexium). Your husband has been using nexium, which is a PPI. PPI are considered the most effective treatments for GERD. This test will confirm if the symptoms your husband has are related to GERD or not and will direct further steps in diagnosis and treatment.
I hope this is helpful and answers to your question but please feel free to let me know if i can assist you any further.
