Being overweight doesn’t just make you heavier—it triggers problems like diabetes and high blood pressure that directly increase your chance of a heart attack or stroke.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.
Systematic Reviews & Meta-Analyses
Max 100Randomized Controlled Trials
Max 90Cohort Studies
Max 72Case-Control Studies
Max 58Cross-Sectional Studies
Max 44Case Reports & Case Series
Max 30Expert Opinion & Narrative Reviews
Max 559 / 72
Evidence Score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

Carrying extra weight makes it more likely you'll have a heart attack or stroke because it pushes up your blood pressure, messes up your cholesterol, and causes body-wide inflammation.
For people who are overweight (BMI 23 or higher), high blood pressure is responsible for about 1 in 5 of the extra heart attack and stroke risk — it’s the second biggest reason after diabetes that extra weight leads to heart problems.
If you’re overweight (BMI 23 or higher), having type 2 diabetes explains about a quarter of why you’re more likely to have heart problems — meaning diabetes is a big reason why extra weight hurts your heart.
If you're overweight (BMI 23 or higher) and have both diabetes and high blood pressure, these two conditions together are responsible for about 19% of your extra heart disease risk — and they make things much worse when they happen at the same time than if you had just one of them.
If you're overweight (BMI 23 or higher) and have kidney disease by itself, it doesn’t really raise your risk of heart problems. But if your kidney disease is caused by high blood pressure or diabetes, then your risk of heart issues goes up a bit.
