Final answer:
HRT can potentially reduce cholesterol levels and prevent cardiovascular disease by increasing estrogen levels.
Step-by-step explanation:
HRT, or hormone replacement therapy, can have an impact on the cholesterol profile by potentially reducing the amount of cholesterol in the blood vessels. Estrogens, which are increased through HRT, have been shown to decrease cholesterol levels and can help prevent cardiovascular disease. However, it's important to note that the use of HRT is still a topic of debate and should be used cautiously, with regular check-ups and in the lowest dose possible for the shortest time possible.
