Alcoholic myopathy is a disease that causes increased muscle weakness and changes in muscle structure, making muscles smaller and less functional. It is caused by long-term alcohol abuse, which impairs muscle recovery and causes inflammation, leading to soreness. Binge drinking can also lead to muscle soreness due to the release of toxins into the bloodstream, which can disrupt immune system functioning. Alcohol also reduces the absorption of insulin, which is necessary for muscle growth, and causes dehydration, which is associated with muscle cramping. In addition, chronic alcohol use can lead to changes in metabolism that cause a buildup of lactic acid, resulting in muscle soreness.

What You'll Learn
Alcoholic myopathy
Acute alcoholic myopathy typically occurs after binge drinking, which involves consuming 4 to 5 alcoholic drinks that result in a blood alcohol level of 0.08 grams per deciliter or higher. This form of myopathy can lead to a potentially life-threatening condition called rhabdomyolysis, where alcohol causes a breakdown of muscle tissue and the release of muscle fibre content, or myoglobin, into the blood. Rhabdomyolysis can cause severe kidney damage and even failure, requiring dialysis treatment. Other symptoms of acute alcoholic myopathy include muscle tenderness, weakness, swelling in affected muscles, dark urine, abnormal walking, and muscle cramps. Acute alcoholic myopathy usually resolves within 1 to 2 weeks of abstinence.
Chronic alcoholic myopathy, on the other hand, is linked to long-term, heavy alcohol consumption. It is associated with cumulative lifetime consumption of alcohol and typically affects individuals between the ages of 40 and 60. This form of myopathy causes progressive proximal muscle weakness over weeks to months and can lead to atrophy, or a decrease in muscle mass. Chronic alcoholic myopathy has a higher incidence in patients with signs of other alcohol-related organ dysfunction, such as cardiomyopathy and liver cirrhosis. It can take longer to recover from chronic alcoholic myopathy, but it is reversible. About 85% of individuals recover within 2 to 12 months of quitting alcohol, and full recovery is typically achieved within 5 years of sobriety.
The exact mechanisms contributing to alcoholic myopathy are multifaceted. Alcohol interferes with the body's ability to build and repair muscle, disrupting protein synthesis and impairing muscle development and recovery. It also causes oxidative stress by generating excessive free radicals that damage tissues and deplete natural protective compounds. Additionally, alcohol consumption leads to deficiencies in various nutrients, including B vitamins, iron, zinc, potassium, and vitamin D, which are crucial for muscle health. These deficiencies further contribute to challenges in converting protein into muscle and repairing muscle fibres.
The treatment for alcoholic myopathy primarily involves abstaining from alcohol. However, due to the challenges associated with alcohol use disorder, a rehab treatment program may be necessary to address cravings and withdrawal symptoms. In some cases, ghrelin injections have been suggested as a potential therapeutic option to help maintain lean muscle mass.

Dehydration and inflammation
Alcohol consumption can lead to dehydration and inflammation in the body, which can cause muscle soreness. Alcohol is a diuretic, which means it increases urine production in the kidneys, leading to a rapid loss of fluids from the body. This can result in dehydration, especially if adequate water is not consumed alongside alcohol. Dehydration can cause headaches, dry mouth, dry skin, and other symptoms that indicate a disruption in the body's hydration levels.
The body prioritizes removing alcohol from the system, treating it as a toxin. This means that when alcohol is consumed, the body focuses on eliminating it instead of breaking down lactic acid, which is a chemical that builds up in the muscles during exercise and causes soreness. Additionally, alcohol inhibits the absorption of insulin, which is necessary for muscle growth and recovery. As a result, alcohol consumption can lead to impaired muscle recovery and increased muscle soreness.
Chronic alcohol use can lead to a condition called alcoholic myopathy, which is characterized by muscle weakness and changes in muscle structure. Alcoholic myopathy can affect the heart muscle, resulting in cardiomyopathy, and can cause breathing problems, stroke, heart attack, heart failure, irregular heartbeat, and severe damage to the heart muscle. Approximately one-third to half of all alcoholics will develop some form of alcoholic myopathy.
Alcoholic myopathy can occur suddenly after a single episode of binge drinking or develop over time due to chronic alcohol use. Acute alcoholic myopathy is typically associated with binge drinking and can be life-threatening. It can lead to rhabdomyolysis, where muscle tissue breaks down and releases toxic proteins into the bloodstream, causing severe damage to the kidneys. Chronic alcoholic myopathy, on the other hand, is related to long-term alcohol use and may take longer to resolve once alcohol consumption is stopped.
In addition to dehydration, alcohol consumption can also cause inflammation in the body. Excessive drinking can lead to inflamed joints, resulting in arthritis and making movement painful. Alcohol abuse can also cause long-term skin issues, such as skin dehydration, redness, and a poor complexion. Inflammation can also occur in the liver, leading to conditions such as cirrhosis, which is a combination of inflammation and scarring that can be fatal if not managed properly.

Lactic acid buildup
Lactic acid is a chemical produced by the body when its cells break down carbohydrates to generate energy. The harder the body works, the more oxygen it requires, and the more lactic acid is produced. Lactic acid is not only produced during exercise; any activity that makes the body use more oxygen than usual can cause a temporary increase in lactic acid.
Lactic acid is cleared out of the body well before muscle soreness sets in. The soreness that follows intense exercise is due to microtears in the muscle fibres and the inflammatory processes required to heal them. This is called delayed onset muscle soreness, or DOMS. DOMS typically occurs 24 to 72 hours after a workout.
Although lactic acid does not cause delayed onset muscle soreness, the burn felt during intense exercise is due to the buildup of hydrogen ions that occurs when lactate is produced. This is not dangerous and is usually symptomless. The body has a natural process for clearing lactate that relies on proper kidney and liver function and oxygen.
Chronic alcohol use can lead to changes in metabolism that cause a buildup of lactic acid. This can lead to muscle soreness that feels similar to post-workout soreness. However, this soreness is not due to microtears in the muscles, as in the case of DOMS.

Impaired muscle recovery
Alcohol has a significant effect on how the body breaks down and builds up muscle. This leads to an imbalance that inhibits muscle growth and makes it harder for muscles to recover. This impaired muscle recovery is crucial to consider for those who work out, as exercise strengthens muscles by causing microscopic damage that heals back stronger. Impaired healing will make it take longer to recover after working out and make exercise less effective.
Drinking alcohol disrupts the signaling pathways that tell the body to build muscle and can contribute to muscle breakdown. Alcohol reduces insulin production, which is a stimulator that allows the body to absorb carbohydrates into the muscles and is necessary for muscle growth. When alcohol is consumed, it limits the absorption ability, impairing muscle development and recovery.
Alcohol also causes oxidative stress and interferes with glycogen and lipid storage, leading to decreased energy and weakness. This improper energy storage can cause problems with muscle contractions, leading to weakness. Additionally, alcohol is a diuretic, which means it can easily contribute to dehydration, causing the body to feel weak. Dehydration is also associated with muscle cramping.
Chronic alcohol use can lead to changes in metabolism that cause a buildup of lactic acid, a chemical that also builds up naturally in the muscles during exercise and causes soreness. When alcohol use causes this buildup, it can lead to muscle soreness similar to that experienced after working out, even though no physical exertion has occurred.
Alcoholic myopathy, a common condition resulting from heavy alcohol use, can also cause impaired muscle recovery. It is characterized by muscle weakness and loss of muscle due to abnormal breakdown of muscle tissue, leading to muscle dysfunction. Acute alcoholic myopathy can occur after a single episode of binge drinking, while chronic alcoholic myopathy results from long-term heavy drinking.

Rhabdomyolysis
Alcoholic myopathy is a disease that causes increased muscle weakness and changes in muscle structure, making muscles smaller and less functional. About half of all alcoholics will develop some form of alcoholic myopathy. This condition can also affect the heart muscle, which is known as cardiomyopathy.
Acute alcoholic myopathy occurs after a single episode of binge drinking and can lead to a life-threatening condition called rhabdomyolysis. Rhabdomyolysis is the breakdown of skeletal muscle tissue, causing the release of myoglobin into the bloodstream. This toxic protein can cause severe damage to the kidneys, potentially leading to kidney failure and the need for kidney dialysis.
Chronic alcoholic myopathy, on the other hand, is related to long-term alcohol abuse and frequent drinking. It develops more slowly than acute alcoholic myopathy but takes longer to resolve once alcohol consumption is stopped. It may persist for several weeks or even up to 12 months after ceasing alcohol consumption.
Alcoholic myopathy can lead to muscle soreness and body aches. Alcohol affects how the body breaks down and builds up muscle, inhibiting muscle growth and impairing muscle recovery. It disrupts the signalling pathways involved in muscle development and reduces insulin production, which is necessary for muscle growth. Alcohol consumption also contributes to dehydration, causing the body to feel weak.
In addition to muscle pain and weakness, symptoms of alcoholic myopathy include fatigue, lightheadedness, muscle twitching, muscle tightness, sensitivity to heat, and a decrease in muscle mass. Treatment for alcoholic myopathy involves stopping alcohol consumption, which typically leads to resolution of the condition. However, in cases of chronic alcoholic myopathy, recovery may take longer, and some heart damage may be irreversible.
