Study of blood lipids under the effect of oral contraceptives

ABSTRACT

Serum cholesterol and beta lipoproteins were studied after the intake of Anovlar and Anovlar 1 tablets for short duration [six months] and long duration [2 to 10 years]. There was a significant increase in total serum cholesterol and in beta [atherogenic] lipoproteins, more marked in the long-term users. The state of hyperlipaemia induced by the combined pills can play a role in the pathogenesis of venous thrombosis, either by accelerating clotting or by inhibiting fibrinolysis
