Alcoholic myopathy is a muscle condition that can affect people with alcoholism or binge drinkers. It causes muscle weakness and wasting, and can lead to acute or chronic alcoholic myopathy. Alcohol abuse can cause muscle twitching, and in some cases, alcohol withdrawal can lead to muscle spasms and twitching. These involuntary muscle contractions could be indicators of underlying nerve damage or other serious health issues exacerbated by alcohol abuse.

| Alcoholic myopathy | Alcoholic myopathy is a muscle condition that can affect people with alcoholism or binge drinkers. |
| It causes muscle weakness and wasting. | |
| About half of all alcoholics will experience some form of muscle weakness as a result of their alcohol consumption. | |
| Acute alcoholic myopathy occurs after binge drinking 4-5 alcoholic drinks in 2 hours. | |
| Chronic alcoholic myopathy is linked to a lifetime of drinking high amounts of alcohol. | |

What You'll Learn
Alcoholic myopathy
Chronic alcoholic myopathy, on the other hand, is linked to long-term heavy drinking over an individual's lifetime. It is the most common form of alcoholic myopathy and is associated with cumulative lifetime alcohol consumption. This type of myopathy is characterised by progressive proximal muscle weakness that develops over weeks to months. It has a higher incidence in patients with other alcohol-related organ dysfunction, such as cardiomyopathy and liver cirrhosis. Those with chronic alcoholic myopathy may also experience episodes of acute alcoholic skeletal myopathy, resulting in a rapid loss of strength and function in skeletal muscles.
The symptoms of alcoholic myopathy vary between individuals, and not everyone will experience all symptoms. Common symptoms include muscle pain, cramping, twitching, tightness, dark urine, sensitivity to heat, and loss of muscle mass. Additionally, alcoholic myopathy can cause difficulties in performing daily tasks and simple movements, such as standing or walking. The condition can also lead to damage to the heart muscle (cardiomyopathy), making it difficult for the heart to pump blood effectively, which can result in breathing problems, stroke, heart attack, heart failure, and irregular heartbeat.
The underlying mechanisms of alcoholic myopathy involve the adverse effects of alcohol on anabolic and catabolic pathways of muscle-mass maintenance. Alcohol increases pro-inflammatory and oxidative stress in skeletal muscles, impairing muscle growth and regeneration. It also interferes with the absorption of essential nutrients, such as protein, iron, B vitamins, and vitamin D, which are crucial for muscle health. Furthermore, alcohol affects the balance of chemicals in the brain, particularly GABA and glutamate, which can lead to muscle tremors and spasms during alcohol withdrawal.

Alcohol withdrawal syndrome
The syndrome typically presents with symptoms such as mild anxiety, gastrointestinal discomfort, headache, insomnia, and hyperactivity. In more severe cases, AWS can lead to alcohol withdrawal delirium, which is characterised by a global confusional state, perceptual abnormalities, and somatic symptoms. Delirium tremens (DT) is a severe form of withdrawal that can occur 48-72 hours after the last drink and can last for up to two weeks.
AWS can also cause muscle tremors or spasms, which are one of the most common symptoms. These tremors can range from mild hand tremors or muscle twitching to more serious full-body seizures. The tremors usually start within a few hours to six hours after the last drink and can last for several days. It is important to note that the severity of spasms can vary, and it is difficult to predict if a person will experience a seizure or delirium tremens. Therefore, alcohol detox and withdrawal should be managed under medical supervision.
The development of acute symptomatic seizures during alcohol withdrawal significantly increases the mortality rate due to complications of severe AUD. Additionally, withdrawal seizures are often associated with concurrent risk factors such as prior epilepsy, structural brain lesions, or the use of other drugs. AWS poses a significant clinical challenge due to its dynamic and complex nature, and early recognition of symptoms is crucial for timely and effective patient care.

Neurodegeneration
Alcohol misuse can trigger neurodegeneration, or the destruction of multiple brain regions, and prevent new brain cell growth. This neurodegeneration impacts the cerebellum, the part of the brain responsible for movement, balance, and coordination, resulting in an often irreversible tremor.
Chronic alcohol misuse can lead to cerebellar atrophy and other degenerative changes that result in significant functional impairment. This may involve excitotoxicity, dietary factors like thiamine deficiency, oxidative stress, compromised energy production, and cell death. One study found that consuming 150 grams of alcohol daily for 10 years resulted in significant cerebellar atrophy in 30% of participants.
Alcoholic neuropathy is a neurological complication of chronic alcohol use, caused by alcohol's toxic effects on neurons and nutritional deficiencies. It refers to nerve damage resulting from heavy alcohol use, with symptoms such as numbness and tingling in the limbs, muscle weakness, and loss of mobility. Up to 66% of people with chronic alcohol use disorder experience some form of alcoholic neuropathy.
Alcohol-related neurologic diseases refer to a range of conditions caused by alcohol intake that affects the nerves and nervous system. These include fetal alcohol syndrome, dementia, and alcoholic neuropathy. Alcohol misuse can also lead to Wernicke-Korsakoff syndrome, a neurological condition caused by thiamine deficiency associated with chronic alcohol abuse.
Alcohol increases the activity of GABA and decreases glutamate activity, causing sedation and muscle relaxation. During alcohol withdrawal, these effects are reversed, with excessive excitatory messages sent to the muscle tissue, triggering spasms and twitching. Muscle tremors are sustained misfirings of the central nervous system, affecting isolated muscle groups and resulting in involuntary movements.

Nutritional deficiencies
Alcoholic myopathy is a condition that causes loss of function and strength in skeletal muscles in response to long-term or heavy drinking. It can occur suddenly after binge drinking or develop over time with regular alcohol use. Binge drinking is defined as consuming four to five alcoholic drinks within two hours.
Alcoholic myopathy can lead to nutritional deficiencies, which can cause muscle twitching. Alcohol can interfere with the absorption of some nutrients, such as protein, iron, B vitamins, and vitamin D, which may affect how well you build and maintain muscle. Vitamin D deficiency can cause muscle twitches because nerve cells need vitamin D to carry messages from the brain to the muscles. Without enough vitamin D, muscles can start to twitch and feel weak.
Magnesium deficiency can also cause muscle twitching as it plays a significant role in keeping nerves and muscles healthy. It helps transfer calcium across the cell membrane to support nerves and muscles. Magnesium deficiencies are common in people with poor diets, excessive alcohol consumption, or recent diarrhoea.
In addition to nutritional deficiencies, alcohol withdrawal syndrome (AWS) can cause muscle twitching. AWS is a set of symptoms that occur when someone who struggles with alcohol abuse stops drinking suddenly. Muscle tremors are one of the most common symptoms of AWS, usually starting within a few hours of the last drink and lasting up to a few days. AWS can also lead to more severe problems, such as seizures and delirium tremens, which can be deadly. Therefore, it is crucial to seek medical help when experiencing alcohol withdrawal.

Electrolyte imbalances
Alcoholic myopathy is a condition that affects the muscles in response to long-term or heavy drinking. It can be caused by binge drinking or can develop over time with regular alcohol use. Alcoholic myopathy can cause electrolyte imbalances, which can harm the muscles. Electrolytes are substances that carry a natural positive or negative electrical charge when they dissolve in water. They help the body regulate chemical reactions and maintain the balance between fluids inside and outside the cells.
Other causes of electrolyte imbalances include loss of body fluids from vomiting, diarrhea, sweating, or high fever, and malabsorption due to stomach disorders, medications, or diet. Electrolyte imbalances can lead to a range of symptoms depending on which electrolytes are affected, such as muscle spasms, weakness, twitching, convulsions, irregular heartbeat, confusion, irritability, and blood pressure changes.
It is important to note that muscle twitching can also be caused by other factors, such as fatigue, dehydration, caffeine use, or exercise. In some cases, muscle twitching may be a symptom of a more serious neurological or underlying condition. Therefore, it is advisable to consult a healthcare professional if you are experiencing frequent or persistent muscle twitching.
