Not a fatal one. Not in a modern society with advanced medical care, such as the world that Padme lived in. Women don't die from childbirth unless there is some terrible complication. I would be willing to grant that her death could be a result of her childbirth if Lucas had put in one solitary line of dialogue to explain that Padme had complications, either from the childbirth or from the force-choking. He pointedly did not. Nothing is ever mentioned about medical complications. The only reason Lucas ever gives us for Padme's death is that she lost the will to live. There's two issues here. One, the notion that a young woman -- a healthy, human woman who is not an elf, or part-elf, and who possesses no unusual physical powers or access to the Force -- would suddenly die for no other reason than a broken heart. That's bad enough. But what makes this truly horrendous storytelling is that this young woman, who according to Lucas simply willed herself to die, is leaving behind two newborn babies. That means Padme made a conscious decision to abandon her children. Children who were effectively fatherless and who needed her desperately, and yet she deliberately chose to leave them and die. Because Lucas couldn't be bothered to give us one valid medical reason to explain Padme's death, this ruins her as a mother and as a character. She never FOUGHT to stay with her babies -- because Lucas never gave her anything to fight against! Physically there was nothing wrong with her. Nothing.
