Alcohol is a toxin that can have both short-term and long-term effects on the body and muscles. While moderate drinking can have some health benefits, excessive alcohol consumption can cause dehydration, electrolyte imbalance, inflammation, and the body's breakdown of alcohol into toxic metabolites. Alcoholic myopathy, a condition that affects the muscles, can develop after binge drinking or chronic alcohol use, leading to muscle weakness, pain, and other symptoms. Alcohol also interferes with muscle growth and recovery by disrupting protein synthesis, hormone levels, and sleep patterns. It's important to understand the effects of alcohol on the body and make informed choices, especially for athletes and those with fitness goals.

What You'll Learn

Alcoholic myopathy
There are two types of alcoholic myopathy: acute and chronic. Acute alcoholic myopathy occurs after binge drinking, typically 4-5 drinks that result in a blood alcohol level of 0.08 grams per deciliter or more. This can lead to a life-threatening condition called rhabdomyolysis, where alcohol causes muscle tissue to break down and release myoglobin into the bloodstream. Rhabdomyolysis can cause severe kidney damage and even failure, requiring dialysis.
Chronic alcoholic myopathy, on the other hand, is linked to long-term heavy drinking. This type of alcoholic myopathy is much more common than the acute form and is associated with a lifetime of excessive alcohol consumption. Over time, excessive alcohol leads to tissue damage and deficiencies in vitamins and minerals such as B vitamins, iron, zinc, potassium, and vitamin D. These deficiencies cause problems with converting protein into muscle and repairing muscle tissue. Additionally, alcohol generates excess free radicals, causing oxidative stress and further tissue damage.
The symptoms of alcoholic myopathy vary between individuals, with acute myopathy manifesting as muscle tenderness, weakness, swelling, and dark urine. It can also lead to kidney failure and abnormal walking. Chronic myopathy, on the other hand, presents with progressive muscle weakness and wasting over weeks to months, affecting muscles near the body's midline, such as the pelvis and shoulders. This can result in difficulties with daily tasks like standing and walking.
The best treatment for alcoholic myopathy is abstinence from alcohol. Acute alcoholic myopathy typically resolves within 1-2 weeks of refraining from alcohol, while chronic myopathy may take longer to recover, with muscle strength and movement improving within 2-12 months of quitting. In most cases, the condition is reversible, with 85% of people achieving full recovery within 5 years of sobriety. However, in some instances, particularly with severe heart damage, the condition may not be reversible.

Dehydration and inflammation
Alcohol is a toxin that can cause dehydration, an electrolyte imbalance, and inflammation in the body. Dehydration and inflammation are closely related. Dehydration does not cause symptom flare-ups, but not drinking enough fluids can worsen pain and inflammation. Our bodies are 60% water, and our organs require water to function correctly. Without sufficient fluids, our bodies struggle to flush out toxins and keep our cartilage and other tissues lubricated.
Our bodies store most of the water in connective tissue, such as tendons, ligaments, and joints, to act as a lubricant. When we become dehydrated, the body will redistribute the water where it is needed. When this happens, toxins can accumulate, and our joints lose much-needed lubrication, resulting in pain and inflammation. Drinking enough water increases synovial fluid production, helping to reduce inflammation and pain.
Alcoholic myopathy is a muscle condition that can affect people with alcoholism or binge drinkers. It happens in about one-third of people with alcoholism. It can come on suddenly after binge drinking or develop over time with regular alcohol use. Alcoholic myopathy can lead to heart muscle damage, or cardiomyopathy, which makes it difficult for the heart to pump blood through the body.
Chronic alcohol use has been found to cause rhabdomyolysis, the breakdown of muscles, in 67% of cases. This causes muscle tissue to break down and release myoglobin into the bloodstream. This toxic protein can cause severe damage to the kidneys.

Impaired muscle growth and recovery
Alcohol consumption has been proven to negatively impact muscle growth and recovery. Firstly, alcohol reduces insulin production, which is necessary for muscle growth as it allows the body to absorb carbohydrates into the muscles. Alcohol also disrupts the body's protein synthesis, hindering the process of building muscle. This is because alcohol is a toxin that the body prioritizes removing, taking longer to rid the body of other toxins and thus impairing muscle development and recovery.
Alcohol also negatively impacts sleep patterns, reducing the amount of Human Growth Hormone (HGH) produced by the body. HGH is needed to help build and maintain muscle. Alcohol increases levels of the stress hormone cortisol, which has the effect of reducing HGH levels. This can lead to a noticeable decrease in muscle strength and mass, or atrophy, with 33% of alcoholics experiencing this.
Alcoholic myopathy is a condition that affects the muscles of those with alcoholism or binge drinkers. It causes loss of function and strength in skeletal muscles and can come on suddenly or develop over time. It can lead to heart damage, kidney failure, and deficiencies in vitamins and minerals. About 85% of people recover within 2 to 12 months of quitting alcohol, but in some cases, heart damage may be irreversible.
Overall, alcohol consumption can cause significant setbacks in gaining muscle and can hinder recovery, making it more difficult to achieve fitness goals.

Hormone disruption
Alcohol can cause both short-term and long-term effects on muscles, including muscle pain, weakness, and reduced strength. Alcoholic myopathy, a condition that affects the muscles, can develop after binge drinking or chronic alcohol use.
Alcohol interferes with the body's hormone system, causing hormonal disturbances that can lead to profound consequences. The endocrine system, which is responsible for communication between various organs, is disrupted by alcohol consumption, affecting the entire body. This disruption can result in various disorders, including stress intolerance, reproductive dysfunction, thyroid problems, immune abnormalities, and psychological and behavioral issues.
The hypothalamic-pituitary-adrenal (HPA) axis, the hypothalamic-pituitary-gonadal (HPG) axis, and the hypothalamic-pituitary-thyroid (HPT) axis are all affected by alcohol use. The HPA axis is responsible for regulating the body's stress response, while the HPG axis plays a crucial role in reproductive functions. Alcohol can decrease testosterone production by inhibiting protein kinase C, a key enzyme in testosterone synthesis. It can also alter estrogen levels in adolescent girls, with effects sustained for long periods.
Alcohol also impacts the HPT axis, which regulates the thyroid hormones thyroxine (T4) and triiodothyronine (T3). These hormones affect every cell and organ in the body, influencing metabolic processes. Additionally, alcohol can interfere with calcium levels in the body, which is necessary for strong bones and communication between cells. Parathyroid hormone (PTH), vitamin D-derived hormones, and calcitonin work to regulate calcium absorption, and alcohol can disrupt these hormones, affecting bone metabolism.
Furthermore, alcohol can increase the stress hormone cortisol, which has been linked to reduced human growth hormone (HGH) levels. HGH is essential for building and maintaining muscle and collagen, and alcohol's disruption of sleep patterns can also decrease HGH production. Alcohol can also cause oxidative stress by increasing free radicals, leading to tissue damage and affecting muscle contractions and strength.

Kidney damage
While alcohol does not directly harm the kidneys, it can cause a range of issues that can lead to kidney damage and disease. The kidneys are responsible for filtering harmful substances from the blood, including alcohol. The more alcohol consumed, the harder the kidneys have to work.
Heavy drinking, defined as more than three drinks a day for women and four drinks a day for men, can lead to dehydration, high blood pressure, and liver disease, all of which can negatively impact kidney function. Dehydration, for example, impairs the normal function of cells and organs, including the kidneys. Liver disease can alter blood flow to the kidneys, reducing their filtering ability. Binge drinking, or consuming five or more drinks within a short time, can lead to acute kidney injury (AKI), a sudden drop in kidney function that can cause lasting damage.
Chronic alcohol use can also lead to tissue damage and deficiencies in essential vitamins and minerals, such as B vitamins, iron, zinc, potassium, and vitamin D. These deficiencies can further impact kidney health. Additionally, alcohol consumption can cause oxidative stress by increasing the production of free radicals, which damage tissues and reduce natural compounds that protect against this damage.
Alcoholic myopathy, a condition caused by long-term or heavy drinking, can also indirectly contribute to kidney problems. This condition affects the proper functioning of muscle fibers, leading to muscle weakness and pain. In severe cases, alcoholic myopathy can cause rhabdomyolysis, a breakdown of muscle tissue that releases myoglobin into the bloodstream. Myoglobin is a toxic protein that can cause severe damage to the kidneys.
It is important to note that the impact of alcohol on kidney health is complex and varies from person to person. While moderate alcohol consumption may not significantly increase the risk of kidney disease for most individuals, those with existing kidney disease should be cautious and consult their healthcare provider for personalized advice.
