Doctors/hospitals/high intervention birth is safest for all women regardless of risk level. Many people have been hitting their heads against THAT brick wall for many years now. Midwives have been proven time and time again to have similar outcomes and less injury to moms.
Take episiotomy....done from 1950 on at almost all doctor-attended births. It was supposed to prevent tearing as the baby emerges, but that's nonsensical, because once you cut something, it tears MORE easily. A study 5 years ago finally brought the rates down from 90% of births to more like 20%, but even then at a frustratingly slow pace. Before that, moms have suffered horrendously and needlessly for decades.
Or cutting the umbilical cord right away, full of precious stem cells and iron. Babies have up to 40% less blood if it's cut right away rather than wait till it shuts off the flow by itself. It was an intervention never proven to be effective, but became the default.
There are two examples of an industry strewn with them.
Zone diet on and off for several years....worked, but too much focus on exact meal composition
Primal since July 2010...skinniest I've ever been and the least stressed about food
