Not usually.  Every insurer has slightly different requirements, but most look for medical issues that are more recent.  Most applications look for medical issues that are either ongoing, have resulted in complications or occurred within the past two or three years.  In the majority of cases, medical issues that are more than two years past and have had no complications will not be an issue.  Some exceptions include (but are not limited to) AIDs, Parkinson ’s disease, Alzheimer’s, COPD, COLD, Lou Gehrig’s disease (ALS) and medical complications that resulted in amputation.
