A number of other health conditions occur more frequently in those with asthma,
including gastro-esophageal reflux disease(GERD), Rhinosinusitis, and obstructive sleep apnea.
Taking into account that in Spain between 0.9 and 1.8 million cases are registered annually,
it is estimated that the approximate cost of acute Rhinosinusitis in our country is between 700 and 1400
million euros each year.
