What diseases are linked to waist circumference in the Styku report?

Styku’s scan report uses waist circumference to estimate a client’s risk for several preventable diseases. This article explains the medical basis for each disease category shown in the report.

  • Abdominal fat promotes chronic inflammation, which may encourage cancer cell growth.
  • Higher levels of hormones like estrogen, produced by abdominal fat, are associated with hormone-sensitive cancers.
  • Cancer types with established links to abdominal obesity include:
    • Colorectal cancer
    • Ovarian cancer
    • Endometrial cancer
    • Postmenopausal breast cancer
  • The report displays a combined risk score across all cancers, not individual cancer types.
  • Note: The report does not account for genetic or hereditary cancer risk.
  • Abdominal fat is more metabolically active than fat elsewhere in the body.
  • It releases fatty acids and inflammatory molecules that can:
    • Build up plaque in the arteries
    • Increase the likelihood of blood clots
    • Raise blood pressure
  • Conditions included under this category:
    • Coronary heart disease (heart attack)
    • Cerebrovascular disease (stroke)
    • Hypertension (high blood pressure)
    • Peripheral arterial disease (atherosclerosis)
  • Abdominal obesity causes systemic inflammation that can lead to airway inflammation, reducing breathing quality.
  • Physical pressure from excess abdominal weight can restrict lung expansion.
  • Conditions that may be affected include:
    • Asthma
    • Chronic obstructive pulmonary disease (COPD)
    • Pulmonary fibrosis

All Other Diseases and All-Cause Mortality

Section titled “All Other Diseases and All-Cause Mortality”
  • A high waist circumference is broadly associated with increased risk across many additional health conditions.
  • All-cause mortality refers to premature death from health-related diseases — a larger waist circumference increases this risk.
  • This category provides a general estimate of overall disease and mortality risk.
  • All disease risk values in the Styku report are derived from peer-reviewed scientific literature.
  • Risk multipliers greater than 1.0 indicate elevated risk; a value of 1.4 means 40% greater risk than baseline.
  • These are population-level estimates and should not be used as a substitute for clinical diagnosis or medical advice.
  • Practitioners can use this information to explain to clients how excess abdominal fat affects health at a physiological level and to support motivation for lifestyle change.
