lifeinthesun, I'm sorry you were scared by the DM.
I know you're not in the UK, but the NICE guidelines on CS here - guidance.nice.org.uk/CG13/Guidance/pdf/English - are what clinical decisions in the NHS are based on, and are the best source of info I'm aware of.
A shorter version 'For pregnant women, their partners and the public' is here - www.nice.org.uk/nicemedia/live/10940/29336/29336.pdf
That said, as Cosmosis and others have pointed out, the 'cause and effect' discussion around CS and risk is not straightforward. Many CS's are carried out because of maternal or foetal health problems which mean they are more likely to experience health issues after birth than mothers and babies who are very low risk - however they are born.
And the NICE guidance is clear about this. The shorter version contains a summary of risks, comparing VB and CS births, but has a disclaimer which reads: - 'It is not clear whether the increased risk of these problems is a RESULT of a caesarean section or BECAUSE of the reasons for needing a CS.' [caps are mine]
If you looked at mortality rates following heart operations, you would see a higher mortality rate than you would for, say, having your tonsils out. However, you wouldn't assume the heart operations were actively causing patient deaths, and cancel them all in the interests of patient safety!
Also, CS statistics do not differentiate between emergency CS's (carried out because there is an immediate and severe problem with mother/baby), and planned CS's, which can be seen more as preventative or pre-emptive action, to avoid emergency problems.
So overall, the risk picture isn't that easy to summarise. (as an aside, something I never see anyone mention is that the risk of physical trauma to the baby is LESS for a CS than for an instrumental VB - and that for mothers, the incidence of bladder incontinence 3 months after the birth is LOWER for those who've had CS births than those who've had VBs. The figure is less than 10 percent for both groups, btw - another thing to be aware of when discussing risk, as others have mentioned. Phrases like 'five times more likely' sound very alarming until you realise that both figures come in at less than 1 percent - like 'death of the mother', for example).
