What does alcohol do to the blood?

Answer 1

Extended alcohol abuse can cause blood conditions including several forms of anemia and blood clotting abnormalities. These conditions could result in susceptibility to bleeding and bruising. Prolonged alcohol abuse can also impair white blood cell function and this makes the abuser more likely to become infected.

Drinking alcohol in moderation promotes good heart and cardiovascular health by improving blood profile. for example, it increases HDL ("good" cholesterol), reduces LDL ("bad" cholesterol), and improves cholesterol particle size.

It decreases dangerous blood clots (thrombosis) by reducing platelet aggregation, reducing fibrinogen, and increasing fibrinolysis. And it reduces coronary artery spasms,reduces blood pressure, reduces blood insulin levels, and increases coronary blood flow.
