Hep C risk factors (odds ratios)
Does not lower BP. The weight gain associated with qutting may cause a small BP rise. Cigarette smoking is an independent cardiovascular risk factor which has a weak association with hypertension.
Reducing salt intake (6g per day)
This is roughly as effective as antihypertensive monotherapy (ie reducing systolic blood pressure by 5-10mmHg). Reducing alcohol intake and taking more exercise have about the same benefit.
Losing weightIf a patient loses 1kg (about 2lb) in weight their blood pressure will fall by 1mmHg. A 10kg weight loss reduces systolic blood pressure by about 10mmHg.
