Many illnesses and leading causes of death can be prevented or delayed with lifestyle changes.
Lifestyle factors:
Can reduce the risk of cardiovascular disease by over 80%
Can reduce the risk of diabetes by over 90%
Are attributed to 40% of dementia cases
Are attributed to 42% of cancer cases
Preventive care matters:
"But preventive care under insurance misses the mark — bloodwork at an average annual physical doesn’t test for 80+ important markers."
Illness is expensive. Even with insurance coverage, co-pays and non-covered services add up.
Treatment costs might look like:
Treating diabetes can cost $12,022 per year out of pocket
Heart failure costs an average of $4,423 per year out of pocket
The average hospital stay in the U.S. costs $2,529 per day out of pocket
The bottom line:
Testing can save you thousands in future health costs.
