Alcoholic myopathy is a disease that causes muscle weakness and changes in muscle structure, and it affects around half of all alcoholics. Alcohol is a toxin that affects how the body breaks down and builds up muscle, inhibiting muscle growth and impairing muscle recovery. This can lead to muscle soreness and body aches. Binge drinking can lead to acute alcoholic myopathy, which causes pain, weakness, and muscle cramps. Chronic alcohol use can also lead to changes in metabolism that cause a buildup of lactic acid, resulting in muscle soreness. Additionally, alcohol increases inflammation throughout the body, which can cause pain in the bones and joints.

What You'll Learn

Alcoholic myopathy
There are two types of alcoholic myopathy: acute and chronic. Acute alcoholic myopathy happens after binge drinking four to five alcoholic drinks, causing a blood alcohol level of 0.08 grams per decilitre or more. It can lead to a potentially life-threatening condition called rhabdomyolysis, where muscle tissue breaks down and releases into the blood. Rhabdomyolysis can cause kidney failure, requiring dialysis. Chronic alcoholic myopathy, on the other hand, is linked to a lifetime of consuming high amounts of alcohol. Over time, excessive alcohol leads to tissue damage and deficiencies in vitamins and minerals, causing problems with converting protein into muscle and repairing muscle.
Symptoms of alcoholic myopathy include muscle pain, weakness, dark urine, cramping, twitching, muscle tightness, sensitivity to heat, and a decrease in muscle mass. It often affects the muscles of the pelvis and shoulders, causing difficulty with daily tasks like standing or walking. Alcoholic myopathy can also lead to heart damage, known as cardiomyopathy, making it difficult for the heart to pump blood effectively.
The best way to treat alcoholic myopathy is to stop consuming alcohol. The condition usually resolves within a few days to two weeks after abstinence. However, for individuals with alcohol use disorder, this can be challenging due to cravings and withdrawal symptoms. In some cases, heart damage from chronic alcoholic myopathy may be irreversible.

Dehydration and inflammation
Alcohol consumption can lead to dehydration, which is associated with muscle cramping and soreness. Alcohol is a diuretic, which means that it increases urine production, and can therefore easily contribute to dehydration. When the body is dehydrated, it causes the body to feel weak.
Drinking alcohol can also increase inflammation throughout the body. This can lead to pain in the bones and joints, and feelings of malaise, which can make it seem like your body is achy and uncomfortable. Alcohol-induced inflammation can also lead to arthritis, which is the result of inflamed joints. Arthritis can make movement painful and is more prominent in those that participate in heavy drinking.
Binge drinking releases toxins into the bloodstream, which can disrupt immune system functioning and lead to soreness after drinking. Even one night of binge drinking can cause this effect. If you engage in regular physical activity, soreness after drinking can be a result of slowed muscle recovery. Alcohol reduces levels of human growth hormone, which plays an important role in muscle recovery. With reduced levels of growth hormone, you’re likely to experience body aches after drinking, especially if you’ve worked your muscles recently through training or exercise.
Chronic alcohol use has been found to cause rhabdomyolysis, which is the breakdown of muscles. A study found that 67% of rhabdomyolysis cases involved alcohol use. Rhabdomyolysis causes muscle tissue to break down and releases myoglobin into the bloodstream. This toxic protein can cause severe damage to the kidneys.
The best way to prevent muscle soreness and other consequences from drinking is to drink in moderation or to stop drinking altogether.

Lactic acid buildup
Lactic acid is produced and metabolized in all cells of the body except red blood cells. When the body breaks down carbohydrates and oxygen levels are low, lactic acid begins to form. It can also build up during intense exercise, severe infection, or chronic alcoholism.
Chronic alcohol use can lead to a condition called alcoholic ketoacidosis, which is a form of metabolic acidosis caused by malnutrition and low blood sugar. Alcohol inhibits the body's ability to produce glucose, leading to a significant production of ketones, which are acidic chemicals. This can result in severe lactic acidosis, which is a rare subtype of lactic acidosis called alcohol-associated lactic acidosis (AALA).
Alcohol-associated lactic acidosis is typically seen in critically ill patients with high blood lactate levels and can be caused by excessive alcohol intake or coexisting conditions such as acute GI bleeding and liver disease. A study found that the survival rate of patients with AALA was not associated with peak blood lactate concentration, although survivors had a better lactate clearance rate.
Lactic acidosis can also occur during extreme exercise, severe dehydration, severe burns, or infection of muscles and tissues. Additionally, drinking alcohol 24 hours before training or competing increases lactic acid levels, which can lead to muscle cramps and a longer recovery period.
Overall, chronic alcoholism and acute alcohol intoxication can contribute to lactic acid buildup and lactic acidosis, a serious medical condition.

Rhabdomyolysis
Alcoholic myopathy is a disease that causes muscle weakness and changes in muscle structure, making muscles smaller and less functional. It can affect both chronic alcoholics and binge drinkers. About one-third of alcoholics will develop alcoholic myopathy.
Chronic alcohol use has been found to cause rhabdomyolysis, a condition where muscle tissue breaks down and releases myoglobin into the bloodstream. This toxic protein can cause severe kidney damage, including acute kidney injury and renal failure. A study found that 67% of rhabdomyolysis cases involved alcohol use.
The classic symptoms of rhabdomyolysis include myalgia, transient muscle weakness, and pigmenturia (dark urine). However, these symptoms are only observed in a small percentage of patients. Other symptoms include diffuse muscle pain that increases with exertion, fatigue, lightheadedness, muscle tightness, and muscle cramps.
Treatment for rhabdomyolysis typically involves aggressive fluid repletion to prevent kidney injury and reduce toxic intracellular content accumulation. In some cases, high-dose corticosteroids have been used successfully to treat the condition.

B vitamin deficiencies
Alcoholic myopathy is a common issue in people who struggle with alcohol use disorder. It is a skeletal muscle dysfunction characterised by muscle weakness, loss of muscle, and pain. Alcoholic myopathy can happen suddenly after binge drinking or develop over time with regular alcohol use. It is caused by abnormal breakdown of muscle tissue and can lead to kidney failure and deficiencies in various vitamins and minerals.
Vitamin B is important for the proper functioning of the body, including muscle health. Deficiencies in vitamin B can lead to a range of symptoms, including muscle weakness, fatigue, and decreased muscle mass. B vitamins are also important for energy production, and their deficiency can result in decreased energy levels and weakness.
Nutritional optimisation, including correcting vitamin and electrolyte deficiencies, is crucial for improving muscle health in individuals with alcoholic myopathy. A balanced diet that includes foods rich in vitamin B, such as beans, poultry, fish, and soy, can help address these deficiencies. Additionally, consulting a doctor about supplementing the diet with vitamin B complexes or other supplements can aid in restoring vitamin levels and improving muscle function.
It is important to note that the best way to cure alcoholic myopathy and prevent further damage is to stop drinking alcohol. Abstinence from alcohol allows for the reversal of symptoms and improvement in muscle strength. In some cases, reducing alcohol consumption can also lead to improvements in muscle health over time.

Frequently asked questions
Yes, alcohol can cause muscle soreness. Alcohol is a toxin that affects the body's muscular system and nervous system, leading to muscle weakness and atrophy.
Alcohol interferes with the body's ability to absorb carbohydrates into the muscles, impairing muscle development and recovery. It also causes dehydration, electrolyte imbalances, and increased inflammation, all of which contribute to muscle soreness.
The only guaranteed way to prevent muscle soreness caused by alcohol is to drink in moderation or abstain from drinking altogether. Staying hydrated, replenishing lost fluids, and getting plenty of rest may also help alleviate muscle soreness after drinking.
