Heavy alcohol use can cause deficiencies in specific components of the blood, including anemia (low red blood cell levels), leukopenia (low white blood cell levels), thrombocytopenia (low platelet levels), and macrocytosis (enlarged red blood cells). Chronic alcohol abuse is known for increasing the likelihood of developing certain medical conditions. Although alcohol has a minimal short-term effect on respiration, extended use can damage the airways by reducing breathing rate, decreasing saliva production, and increasing the risk for bacteria in the mouth.
How Drug and Alcohol Addiction Affect Your Immune System
As the immune system grows weaker, you’re left more vulnerable to infections, poor organ function, and disease. Sign up for our Newsletter and receive the latest on addiction treatment news. Keep up on new treatment methods, new intervention methods, new self help techniques, new drug and alcohol rehab centers and much more. Treatment remains the most effective way to help those struggling https://veritasbiomass.com/why-does-alcohol-cause-hypertension-2/ with drug or alcohol addiction.
Why does substance abuse increase the risk of infections?
Nutrients such as vitamin C, vitamin D, zinc, and omega-3 fatty acids are particularly important for a healthy immune response. At Cymbiotika, we offer a range of science-backed does alcohol weaken your immune system supplements to help fill nutritional gaps and support overall well-being. Alcohol can affect behaviors that increase the likelihood of acquiring or transmitting HIV to others. Alcohol may also speed HIV progression in people living with the disease, influence their engagement and retention in HIV treatment, and increase their susceptibility to organ damage and coinfections. Alcohol interferes with the brain’s communication pathways and can affect the way the brain looks and works.
Mental Health
The risk of developing heart problems is also an issue for those who drink to excess. Alcohol raises triglycerides in the blood, which can block arteries and cause problems such as high blood pressure and heart disease. Once a wound has healed, excess alcohol can impair the ability of your immune system’s macrophages, also known as “scavenger” cells, to remove excess scar tissue. Interferon causes your body to be less able to fight off infections, including COVID-19.
- Alcohol exposure, and particularly chronic heavy drinking, affects all components of the adaptive immune system.
- Chronic alcohol consumption, regardless of the source, weakens immune function.
- Immune cells identify threats by recognizing the structures common to bacteria, viruses, and other microbes.
- Injection drugs come with even higher risks, such as collapsing veins and infected blood vessels or heart valves.
After binding to LPS, monocytes are activated and mature into macrophages that travel to the site of infection to secrete important cytokines for what is alcoholism the inflammatory response. Several studies have demonstrated the dose-dependent effect that alcohol has on preventing both monocytes and macrophages from binding to the bacterial cell wall component lipopolysaccharide (LPS). Weakened immunity from drugs or alcohol makes it harder for the body to defend itself against harmful bacteria and viruses. The hypothalamic–adrenal–pituitary axis is a hormonal system that primarily is involved in the stress response. Activation of this system culminates in the production and release of corticosteroid (i.e., cortisol in humans and corticosterone in rodents) from the adrenal glands, which then act on various tissues to mediate the stress response.
Can Alcohol Consumption also Affect the Immune System?
Articles published in the last 20 years (January 2003 to November 2023) were included. Gateway Foundation provides treatment services at all levels of care, whether you are a good candidate for outpatient treatment or need the dedicated care offered by residential programs. If you or someone you care about needs help overcoming drug or alcohol addiction, call Gateway or request more information online. For this reason, it can be challenging to turn your focus and energy to a regular exercise plan.

- When our immune systems are not interrupted by harmful pathogens, bodily functions will run smoothly.
- To explore drugs predicted to influence a portion of the adaptive immune system, we identified a subnetwork based on the largest magnitude immunemod scores for T cell subsets and tissues (Supplementary Fig. 11).
- Before diving into the impact of drugs on the immune system, let’s establish a foundational understanding of what the immune system is and how it functions.
Whether these changes are long lasting still remains unclear, as reports in cocaine-addicted individuals are inconsistent 18,27. Prolonged dopamine induced activation is responsible for the suppression of NK-cell proliferation 28, which would be a possible scenario in cocaine addiction. Considering the major role that NK-cells play in anti-viral immune defense, these undesired changes in the levels of NK-cells may have severe consequences on immunity. In response to any type of stress, release of corticotropin-releasing hormone (CRH) and increased peripheral glucocorticoid levels initiate a cascade of biological responses that help counteract the altered homeostatic state. Parvocellular neurons in the paraventricular nucleus (PVN) of the hypothalamus synthesize and secrete CRH into the hypothalamic-pituitary portal network that connects the hypothalamus and the anterior pituitary. At the anterior pituitary, CRH stimulates the synthesis and secretion of a proopiomelanocortin (POMC)-derived peptide called adrenocorticotropic hormone (ACTH) from corticotropic cells.
These disruptions can change mood and behavior and make it harder to think clearly and move with coordination. More information about alcohol’s effects on the brain is available on NIAAA’s topic page on Alcohol and The Brain. Current research points to health risks even at low amounts of alcohol consumption, regardless of beverage type.
These data suggest that differences in the activity of the HPA axis may help determine whether certain individuals are at high risk for developing alcohol-related disorders and alcoholism. The negative effects of ethanol lead to alcoholic cirrhosis, where healthy liver tissue is replaced by scar tissue. This impairs liver function, affecting its role in detoxification and metabolism.
Impact of AUD on B cells
Additional studies in rodents assessed the effects of alcohol on the effectiveness of bacillus Calmette-Guérin (BCG) vaccination, which protects against tuberculosis. The studies found that when animals consumed ethanol before BCG vaccination, they were not protected against a subsequent pulmonary challenge with M. In contrast, mice that consumed ethanol after the BCG vaccination were protected against a subsequent M. Taken together, these data suggest that chronic ethanol exposure interferes with immunity to new antigens but not with immunity established before alcohol consumption. Alcohol-induced hyperprolactinemia has also been demonstrated in nonhuman primates and laboratory animals. Studies conducted in macaque female monkeys showed that the PRL levels were elevated after chronic self-administration of alcohol (3.4 g/kg/day)85, 86.
