These are the factors driving your profile, and what usually helps most.

Age
Risk rises with age — regular blood pressure and cholesterol checks matter more from 40 onwards.

This is an educational risk-factor profile, not a validated clinical score such as SCORE2 or QRISK, which need blood pressure and cholesterol measurements. BMI does not distinguish muscle from fat and is less reliable in athletes, pregnancy, and older adults. Nothing you enter is stored, sent or logged. If you have chest pain, breathlessness at rest or collapse, call 112 or 999.
