Which combination is associated with a 400-700% increased risk of premature death?

• A. Diabetes & bleeding gums
• B. Heart disease & obesity
• C. Smoking & high cholesterol
• D. High blood pressure & age

Answer: (A)

When two health factors interact in a way that amplifies risk beyond simply adding their separate effects, you’re looking at a synergistic danger to health. Diabetes and periodontal (bleeding) gums fit this pattern because diabetes compromises immune function and promotes inflammation, while periodontal disease is a chronic infection that keeps systemic inflammation elevated and can worsen insulin resistance and vascular damage. Put together, these effects accelerate the kinds of complications—especially cardiovascular and kidney problems—that lead to premature death, producing a much higher mortality risk than either condition alone. That’s why this pairing is described as associated with a very large increase in risk.

Other risky combinations are indeed dangerous, but the dramatic 400-700% figure is most commonly linked to the combination of diabetes with periodontal disease in educational contexts, reflecting this strong synergistic impact. Maintaining good blood sugar control and oral health helps mitigate this combined risk.
