What you will learn

• Alcohol myopathy refers to a condition in which muscle tissue is damaged due to the use of alcohol.
• Alcohol myopathy can be acute or chronic.
• If you experience muscle pain, dark urine, or unexpected weakness or fatigue, it is possible that you may have rhabdomyolysis, and you should seek medical attention immediately.
• Alcohol myopathy recovery is possible, and recovery time depends on whether the condition is acute or chronic.

If you’ve noticed new muscle weakness, cramping, or any problems walking, you might not have connected it to your alcohol use.

But the truth is these changes can be linked to heavy alcohol use.

This guide is for anyone dealing with these changes and for the loved ones who are worried about them. We’ll explain how alcohol can affect the muscles and nerves, what the signs look like, and how treatment and recovery work.

What is Alcohol Myopathy?

Alcoholic myopathy is a type of muscle dysfunction caused by alcohol consumption that affects skeletal muscles that manage movement, posture, and daily body functions.[1]

There are two main patterns:

• Acute alcoholic myopathy is muscle tissue injury that can happen after a binge drinking episode or in the first days of alcohol withdrawal.[2]
• Chronic alcoholic myopathy develops gradually and causes muscle weakness, wasting, and gait problems after long-term alcohol use.[3]

Other alcohol-related muscle problems can also develop, such as electrolyte-associated myopathy and damage to the heart muscle.[4] Because many diseases share these symptoms, anyone suspected of having alcoholic myopathy should see a licensed medical professional.

How Alcohol Use Affects Muscles

Alcohol use can impair muscle repair and long-term maintenance, since both acute and chronic use can reduce muscle protein synthesis, increase muscle protein degradation, and interfere with mitochondrial function and tissue remodeling.[5]

The degree of muscle damage caused by alcohol consumption varies based on the pattern and frequency of alcohol consumption. Acute alcohol-induced muscle injury may occur after one binge drinking episode, while long-term and heavy alcohol consumption may cause chronic muscle damage associated with alcohol myopathy.

The symptoms associated with acute muscle damage typically subside within one to two weeks once drinking stops. However, the recovery time varies based on the extent of the muscle damage and if there are any complications.[6]

Risk factors may include:

• Chronic heavy drinking
• Binge drinking
• Malnutrition
• Inactivity
• Chronic infection
• Prolonged illness.
• Existing muscle weakness from other conditions

Recognizing Alcohol Myopathy Symptoms

Symptoms of alcohol myopathy vary based on whether the injury is acute or chronic and can range from subtle changes in strength to severe muscle breakdown.

Common chronic myopathy symptoms may include:

• Painless muscle weakness
• Reduced muscle mass
• Difficulty standing after sitting or climbing stairs
• Difficulty lifting objects overhead
• An unsteady or altered gait
• Muscle cramps or localized pain
• Gradually declining physical endurance

Chronic alcoholic myopathy may also cause weakness and atrophy of the proximal muscles in the hips and shoulders that take weeks or months to develop and may cause serious loss of muscle mass.[7]

These changes call for an evaluation rather than trying to find the cause from symptoms alone.

Alcohol-related muscle injury can range from a temporary increase in creatine kinase, sometimes without clear symptoms, to rhabdomyolysis with myoglobin in the urine, and the severity can vary.[8] A clinician may need to assess the symptoms, alcohol use, physical exam, and appropriate medical tests.

Acute Alcoholic Myopathy and Emergency Signs

Acute alcoholic myopathy symptoms overlap with those of rhabdomyolysis, a rapid breakdown of muscle tissue. The contents of the damaged muscle cells can enter the bloodstream and contribute to acute kidney injury, abnormal electrolyte levels, and blood clotting problems.[9]

Warning signs can include:

• Sudden or severe muscle pain
• Marked muscle weakness
• Swelling or tenderness
• Dark, reddish-brown, or tea-colored urine
• Feeling unusually weak or tired
• Reduced urine output
• An irregular heartbeat, confusion, or other symptoms that get worse quickly

Call 911 or seek emergency medical care for dark urine with muscle pain or weakness, severely reduced urine output, confusion, collapse, or other serious symptoms. Rhabdomyolysis can lead to kidney failure and requires prompt medical assessment.

Don’t wait until all the classic signs are present. The combination of muscle pain, weakness, and reddish-brown urine shows up in fewer than 10% of people with rhabdomyolysis, and missing one sign does not rule it out. [10]

Acute alcoholic myopathy can also occur during alcohol withdrawal. Severe alcohol withdrawal can include agitation, hallucinations, disorientation, fever, sweating, high blood pressure, and a fast heart rate, with the most severe symptoms usually developing three to eight days after stopping alcohol.[11] People concerned about physical dependence on alcohol should speak with a licensed professional before stopping abruptly, and those with severe alcohol withdrawal symptoms should seek emergency care.

Chronic Alcohol-Related Muscle Effects

The chronic form usually progresses more subtly. Muscle weakness or wasting may appear in the muscles around the shoulders and hips. It typically does not cause intense pain, but the muscle weakness also affects balance and the ability to perform routine tasks.

Alcoholic myopathy may affect 40% to 60% of people who drink heavily, and alcohol-related muscle disease has also been reported more often than liver cirrhosis among people with alcohol use disorder.[12] These figures describe studied populations and cannot determine any one person’s risk.

Alcoholic Myopathy vs. Alcoholic Neuropathy

Both alcoholic neuropathy and alcoholic myopathy can cause weakness and difficulty walking, but they are two different disorders and the way they affect the body is completely different.

Alcoholic neuropathy affects the peripheral nervous system, while alcoholic myopathy is characterized by muscle problems.[13]

Symptoms such as numbness, tingling, burning sensations, changes in reflexes, or problems with balance can help the health professional determine the appropriate evaluations.

Not all walking problems are caused by muscle weakness, and a medical provider might determine whether the problems are a result of alcoholic neuropathy, alcoholic myopathy, an electrolyte problem, or another condition.

Alcohol Use Disorder and Alcoholic Myopathy Treatment

The cornerstone of treatment for alcoholic myopathy is to stop drinking and adjust nutrition to address vitamin and electrolyte deficiencies, which is associated with greater improvement in muscle health.[14] A clinician can advise whether a balanced diet, B vitamins, or other nutritional measures are appropriate on a case-by-case basis.

Treatment can also include:

• Emergency or inpatient care for complications like rhabdomyolysis or kidney problems
• Ongoing clinical monitoring of muscle and organ function
• Individualized nutrition guidance from a qualified professional
• Physical therapy if a licensed medical provider recommends it
• Alcohol use disorder treatment to help people stop drinking

Acute rhabdomyolysis with myoglobinuria requires urgent inpatient treatment, including monitoring kidney function and correcting dangerous potassium abnormalities. Intravenous fluids may reduce the likelihood of kidney failure and the need for dialysis.

Alcohol use disorder can be treated with behavioral treatment, medication, or both.

What to Expect From Alcohol Myopathy Recovery

It is possible for muscles to recover from alcoholic myopathy, though the recovery time varies and depends on whether the myopathy is acute or chronic, the degree of muscle damage, and any other existing health problems.

Acute alcoholic myopathy can reverse after a few days to several weeks of abstaining from alcohol; however, recovery from chronic myopathy can be a slow process lasting 2 to 12 months.[15]

Recovery from alcoholic myopathy is possible if you stop drinking alcohol, eat a balanced diet, treat any nutrient deficiencies, and slowly build up physical activity with a healthcare provider’s guidance. Do not exercise hard if it causes too much pain, if you are too weak, or if you notice dark urine. If your symptoms change suddenly or get worse, get medical care.
