Alcohol, as well as alcohol-induced cirrhosis, leads to decreased red blood cell (RBC) production. Hypersplenism, a condition characterized by an enlarged spleen and deficiency of one or more blood cell types, can induce premature RBC destruction. Blood loss occurs primarily in the gastrointestinal tract (e.g., at the sites of peptic ulcers) and is increased in patients with reduced platelet numbers. Folic acid deficiency impairs RBC production and results from decreased ingestion, decreased absorption, and abnormal metabolism of folic acid.
How does alcohol consumption affect my high cholesterol or risk of other cardiovascular issues?
While alcohol may have blood thinning effects, it may also increase the risk of cardiovascular conditions and blood clots. Research suggests drinking alcohol may thin the blood by affecting platelets, which are the parts of blood that initiate coagulation, or clotting. Evidence of oxidative stress is found after short periods of alcohol consumption (2 to 18 weeks), at least in animal models. These data suggest that antioxidant defense mechanisms that attempt to protect the heart against oxidative damage appear to be initiated soon after drinking alcohol. Also, as noted below, data from other studies demonstrate the protective role of administered antioxidants, such as a synthetic compound that mimics the native superoxide dismutase enzyme, called a superoxide dismutase mimetic. This suggests a direct or indirect role for ethanol-mediated oxidative stress in the heart (Jiang et al. 2012; Tan et al. 2012).
Effect of alcohol intoxication on the risk of venous thromboembolism
The associations between drinking and CV diseases such as hypertension, coronary heart disease, stroke, peripheral arterial disease, and cardiomyopathy have been studied extensively and are outlined in this review. Although many behavioral, genetic, and biologic variants influence the interconnection between alcohol use and CV disease, dose and pattern of alcohol consumption seem to modulate this most. Low-to-moderate alcohol use may mitigate certain mechanisms such as risk and hemostatic factors affecting atherosclerosis and inflammation, pathophysiologic processes integral to most CV disease. Both the negative and positive effects of alcohol use on particular CV conditions are presented here. The review concludes by suggesting several promising avenues for future research related to alcohol use and CV disease. The cohort studies and case-control studies (hereafter referred to as ‘conventional observational studies’) used in these meta-analyses are known to be subject to various types of bias when used to estimate causal relationships11.
Alcohol’s Effects on Iron Metabolism
- However, in a recently conducted Mendelian randomization study, Vu and colleagues (2016) reported that low-to-moderate alcohol consumption reduced triglyceride and LDL-c and increased HDL-c, in particular the HDL2-c subfraction.
- The AI cohort exhibited a higher hazard ratio for individuals aged between 20 and 50 years.
- Depending on who you ask, you might be told to drink a few glasses of red wine a day or to avoid alcohol altogether.
Alcohol-induced structural abnormalities in red blood cell (RBC) structure. (A) Normal RBC’s have a characteristic disclike shape; the cell in the center is a neutrophil. (B) Stomatocytes have a defect in their membranes that causes them to assume a mouth-, or stoma-, like shape when viewed under a microscope. (C) Spur cells are characterized by spikelike protrusions that result from the assimilation is alcohol a blood thinner of excess cholesterol into the cell’s membrane. The NHIRD covers nearly 99% of the population of Taiwan and is a representative data source that includes age, sex, and comorbidity information. Because each resident in Taiwan is assigned a unique personal identification number, all of the study participants could be traced through the NHI records for the entire follow-up period.
Thus, alcohol is directly toxic to the bone marrow, which contains the precursors of all blood cells, as well as to the mature cells circulating in the bloodstream. Moreover, long-term excessive alcohol consumption can interfere with various physiological, biochemical, and metabolic processes involving the blood cells. They include anemia, which in severe cases can have debilitating effects; an increased risk of serious bacterial infections; and impaired blood clotting and fibrinolysis, which can cause excessive bleeding and place the drinker at increased risk of strokes. These direct effects may be exacerbated by the presence of other alcohol-related disorders, such as liver disease and nutritional deficiencies. Abstinence can reverse many of alcohol’s effects on hematopoiesis and blood cell functioning.

- Neutrophils obtained from intoxicated volunteers had the same defect.
- MTOR regulates cell growth, proliferation, motility, and survival; protein synthesis; and transcription (Donohue 2009).
- Both the negative and positive effects of alcohol use on particular CV conditions are presented here.
- And if you have an underlying health condition such as diabetes or kidney disease, ask your doctor whether it’s safe for you to drink at all.
These direct and indirect effects of alcohol can result in serious medical problems for the drinker. For example, anemia2 resulting from diminished RBC production and impaired RBC metabolism and function can cause fatigue, shortness of breath, lightheadedness, and even reduced mental capacity and abnormal heartbeats. Finally, alcohol-induced abnormalities in the plasma proteins that are required for blood clotting can lead to the formation of blood clots (i.e., thrombosis).
