Obesity is associated with significantly lower circulating levels of B-type natriuretic peptide (BNP) and N-terminal pro-atrial natriuretic peptide (N-ANP) compared to lean individuals, independent of hypertension and diabetes status.
If you are obese, your body's natural blood pressure-regulating hormones (BNP and ANP) are likely suppressed, which may contribute to higher blood pressure. This is not just about 'stress' on the heart; it involves how fat tissue clears these hormones. Weight loss may help restore these protective hormone levels.
GoodSupportsHIGH confidence
Obese individuals have low circulating natriuretic peptide levels, which may contribute to their susceptibility to hypertension and hypertension-related disorders.
Why this rating
Large sample size (n=3389), multivariable adjustment, and consistent findings across two peptide types.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
