Imagine you have a leaky roof. The roofer comes over, puts down some buckets, hands you a hefty bill and leaves without fixing the roof.
You'd never tolerate that, right?
Yet something similar happens in medicine all the time, and patients rarely complain.
Excessive weight is the underlying repairable cause of most chronic illnesses treated today. But instead of tackling the weight problem (the leaky roof) patients often take medications (buckets) for the illnesses caused by their weight problem.
