Alcoholic myopathy is a condition that can affect people with alcoholism or binge drinkers. It involves muscle weakness and loss of muscle due to the abnormal breakdown of muscle tissue. Alcohol can also decrease the body's ability to absorb nutrients, which further affects muscle health. Alcoholic myopathy can lead to major complications such as high levels of potassium in the blood, kidney failure, and even heart failure. In addition, alcohol can cause dehydration, impair sleep patterns, and increase blood pressure, all of which can negatively impact muscle performance and overall physical health. While moderate alcohol consumption may not significantly affect the musculoskeletal system, excessive or long-term alcohol misuse can lead to serious health problems, including liver disease, cancer, and heart issues.

What You'll Learn
Alcoholic myopathy
There are two types of alcoholic myopathy: acute and chronic. Acute alcoholic myopathy occurs after binge drinking 4 to 5 alcoholic drinks, causing a blood alcohol level of 0.08 grams per deciliter or more. This can lead to a potentially life-threatening condition called rhabdomyolysis, where alcohol causes muscle tissue to break down and release into the blood. Chronic alcoholic myopathy, on the other hand, is linked to a lifetime of drinking high amounts of alcohol. Over time, excessive alcohol consumption leads to tissue damage and deficiencies in essential vitamins and minerals such as B vitamins, iron, zinc, potassium, and vitamin D. This causes problems with converting protein into muscle and repairing muscle.
The best way to cure alcoholic myopathy is to stop drinking alcohol. In most cases, the condition resolves within a few days to two weeks after abstaining from alcohol. For chronic alcoholic myopathy, symptoms can take longer to resolve, ranging from two to twelve months. Medical treatment can help improve symptoms more quickly, but the first step is always to address the underlying alcohol use disorder.

Alcoholic neuropathy
The exact cause of alcoholic neuropathy is not fully understood, but it is believed to be multifactorial, resulting from both the direct toxic effects of alcohol on neurons and the malnutrition induced by alcohol abuse. Alcohol inhibits the absorption of key nutrients, such as thiamine (vitamin B1), which is important for neuron development and carbohydrate metabolism. Vitamin B1 deficiency can lead to cell membrane damage and irregular cell growth in the nervous system. Other vitamin deficiencies associated with alcohol abuse include B vitamins, folic acid, and vitamin E.
The symptoms of alcoholic neuropathy are similar to those of peripheral neuropathy and can affect both controlled and involuntary movements, as well as sensations. Patients with alcoholic neuropathy often present with pain, ataxia, and paresthesias in the lower extremities. Additionally, alcoholic neuropathy can cause impotence, diarrhea, constipation, and other symptoms that may respond poorly to treatment.
The only known way to prevent alcoholic neuropathy is to avoid excessive alcohol consumption. Treatment for alcoholic neuropathy focuses on alcohol sobriety and the replacement of key nutrients. Early diagnosis and treatment can increase the chances of full recovery, and support systems and professional services are available to help individuals quit drinking.
While nerve damage caused by alcoholic neuropathy can sometimes be permanent, research suggests that some or all of the damage can be reversed with sobriety. However, symptoms are likely to worsen if alcohol consumption continues, and severe cases may lead to chronic pain, damage to the arms and legs, and impaired quality of life.

Dehydration and physical performance
Dehydration is a condition where the body loses more fluids than it takes in, causing the body to not function normally. It is essential to drink plenty of water to stay hydrated and replace water lost through physical activity. Alcohol is a diuretic, meaning it increases urine output, and can therefore lead to dehydration. However, some sources argue that alcohol does not cause significant dehydration, and that the negative effects associated with it are due to other factors such as poor sleep, gut irritation, and the toxic byproduct acetaldehyde.
Exercising requires normal levels of sugar in the blood to provide energy. Alcohol reduces the body's ability to convert food to energy, lowers blood sugar levels, and increases insulin secretion, leading to hypoglycemia. This negatively affects sporting performance. Alcohol also reduces testosterone levels, which are necessary for muscle development and recovery.
Drinking alcohol before or after exercise can negatively impact performance. Alcohol consumption can lead to dehydration, which can affect multiple parts of the body and impair physical performance. It can also cause an increase in lactic acid, which leads to muscle soreness, discomfort, and fatigue. Additionally, alcohol consumption can negatively impact sleep, causing drowsiness and low energy the next day, which can also affect athletic performance.
To prevent dehydration, it is recommended to drink water throughout the day and avoid diuretics such as alcohol and caffeine. Active individuals should pay close attention to their fluid intake before, during, and after physical activity to maintain proper hydration levels and optimize their physical performance. It is advised to consume fluids with electrolytes, such as sports drinks, to replace lost minerals and maintain nerve and muscle function.
In summary, dehydration caused by alcohol consumption can impact physical performance by affecting the body's fluid balance, energy levels, muscle recovery, and overall health. Therefore, it is important to prioritize proper hydration and limit alcohol intake to maintain optimal physical performance.

Nutritional deficiencies
Alcoholic myopathy is a muscle-wasting condition linked to chronic alcohol use. It affects the core muscles, including those in the shoulders, hips, and thighs. The condition manifests as rhabdomyolysis, which is a breakdown of muscle tissue and the release of muscle-fibre content into the blood. This can lead to kidney failure and kidney dialysis, a treatment that uses machines to filter the blood for the kidneys.
Chronic alcohol consumption can lead to nutritional deficiencies, disrupting nutrient absorption and causing deficiencies in protein, iron, B vitamins, and vitamin D, all of which are vital for muscle health. Binge drinking can also cause acute alcoholic myopathy, which can lead to rhabdomyolysis. Over time, excessive alcohol consumption leads to tissue damage and deficiencies in B vitamins, iron, zinc, potassium, and vitamin D. This causes problems with converting protein into muscle and repairing muscle.
Alcohol inhibits the absorption and usage of vital nutrients such as thiamin (vitamin B1), vitamin B12, folic acid, and zinc. Folic acid is integral to the formation of new cells, and a lack of it can cause a blood disorder called "megaloblastic anemia," which lowers the oxygen-carrying capacity and negatively affects endurance activities. Zinc is essential for energy metabolic processes, and its depletion due to alcohol consumption results in reduced endurance.
Alcohol also disrupts the mitochondria, impairing energy production and muscle strength. It interferes with the production of adenosine triphosphate (ATP), the source of energy for muscle contractions. Additionally, alcohol reduces energy sources by inhibiting gluconeogenesis, a process that forms glucose from non-glucose substances. This loss of ATP results in a lack of energy and endurance.
To address nutritional deficiencies caused by alcoholic myopathy, medications such as B vitamins may be prescribed to promote muscle health. Nutritional therapy is a key strategy in the treatment process, along with alcohol abstinence, physical rehabilitation, and symptom management.

Cardiomyopathy
Alcoholic cardiomyopathy (ACM) is a disease caused by the long-term consumption of alcohol, leading to heart failure. The heart is unable to pump blood efficiently, causing severe problems. ACM is characterised by ventricular dilation and impaired cardiac function, with the left ventricle being particularly affected. It is a leading cause of non-ischemic dilated cardiomyopathy, with the major risk factor being chronic alcohol use.
The exact mechanism by which alcohol causes ACM is not fully understood, but it is believed to be multifactorial, involving genetic, environmental, and lifestyle factors. One key factor is thought to be mitochondrial damage due to oxidative stress injury. Alcohol consumption increases mitochondrial fragmentation and reactive oxygen species (ROS) levels in myocytes, leading to oxidation of lipids, proteins, and DNA, resulting in cardiac dysfunction. Additionally, chronic alcohol consumption can cause vitamin and mineral deficiencies, such as thiamine, magnesium, and selenium, which are crucial for proper heart function. Thiamine deficiency can lead to beriberi, damaging the heart muscle.
The signs and symptoms of ACM can vary depending on its severity. In the early stages, individuals may not experience any noticeable symptoms. However, as ACM progresses, they may develop fatigue, shortness of breath, palpitations, lightheadedness, swelling of the legs and ankles, chest pain, and heart murmurs. In some cases, ACM can lead to arrhythmias or irregular heart rhythms, which can range from mild to severe and may cause lightheadedness or even loss of consciousness.
The treatment for ACM involves lifestyle changes, including complete abstinence from alcohol, a low-sodium diet, and fluid restriction. Medications such as ACE inhibitors, beta-blockers, and diuretics may also be prescribed to reduce strain on the heart. In severe cases, surgical insertion of an ICD or pacemaker may be necessary to improve heart function. It is important to note that the diagnosis of ACM is typically made based on a combination of medical history, physical examination, and diagnostic tests, with the key diagnostic element being the absence of coronary artery disease.
