Withdrawal Syndromes

What is Withdrawal Syndromes?

Many people around the world experience withdrawal symptoms when they stop taking drugs or alcohol. How a person responds to withdrawal depends on how long and how much they’ve used a particular substance. It varies widely from person to person regarding how long they’ve been using.

For instance, if someone drinks alcohol consistently for 1 to 3 months, or heavily for about a week to ten days, they can start experiencing withdrawal symptoms within 6 to 24 hours after they stop drinking. These symptoms reduce as soon as the person consumes more alcohol.

What Causes Withdrawal Syndromes?

Your body constantly tries to stay balanced and stable, in a state known as homeostasis. When a substance – such as alcohol, opioids, or benzodiazepines – is removed from your body, it can upset this balance. The body’s automatic reaction to counter these substances is suddenly unopposed, leading to withdrawal symptoms.

Alcohol’s impact and withdrawal are quite complex. These effects are primarily due to alcohol’s interaction with chemicals in the brain called neurotransmitters and neuroreceptors, including gamma-aminobutyric acid (GABA), which reduces activity in the nervous system, and glutamate, which generally increases it. Alcohol changes how these chemicals work, upsetting the brain’s chemical balance and leading to withdrawal symptoms. Long-term use of alcohol suppresses the activity of opioid receptors, which control pain and pleasure responses in the brain. This suppression increases the number of these receptors. These receptors in certain parts of the brain also control the release of dopamine, a ‘feel-good’ brain chemical, when you consume alcohol, contributing to alcohol cravings. Medications that block these receptors can help reduce these cravings.

In the case of addictions to opioids or benzodiazepines, chronic use of these drugs suppresses the body’s natural production of chemicals like neurotransmitters, which transmit signals in the brain, endorphins, which help counteract pain, or GABA. When you stop using the drug, your body isn’t creating enough of these endogenous (from within your body) transmitters to balance out the ones that counter the drug. This leads to withdrawal symptoms. How quickly your body can start producing these neurotransmitters again determines when withdrawal symptoms start.

Risk Factors and Frequency for Withdrawal Syndromes

Withdrawal from drugs and alcohol is a widespread health issue. A large number of adults in emergency rooms might be dealing with an alcohol use disorder, and a significant fraction of those admitted to Intensive Care Units could have alcohol withdrawal symptoms. It is worth noting that only about a quarter of people with an alcohol use disorder have ever received treatment. Alcohol withdrawal can lead to extended hospital stays and even increase the risk of death. This condition is more prevalent in men than women.

Without treatment, the death rate from alcohol withdrawal can be high. Roughly 5% of these patients might develop a severe condition called delirium tremens when they stop using alcohol. The exact number of people addicted to opioids, sedatives, and stimulants is not clear. While withdrawal from benzodiazepines can be a medical emergency due to the potential for seizures, being intoxicated on them is generally less serious. Opiate withdrawal can be highly uncomfortable, but it rarely causes death. Withdrawal from stimulants like cocaine and amphetamines typically results in drowsiness and symptoms similar to a condition called adrenergic blockade, but it’s rarely fatal.

The estimated lifetime occurrence of alcohol use disorder is 12.8%, and 4.8% annually.
About 20% of adults in emergency rooms could be suffering from an alcohol use disorder.
Approximately 4-40% of patients in the ICU may exhibit alcohol withdrawal symptoms.
Only 24% of people with an alcohol use disorder have ever been treated.
Patients with alcohol withdrawal symptoms often have longer hospital stays and a higher risk of death.
Alcohol withdrawal is more common in men.
Untreated alcohol withdrawal can have a high mortality rate.
About 5% of patients undergoing alcohol withdrawal might develop delirium tremens.
Benzodiazepine withdrawal is a medical emergency due to the risk of seizures, but intoxication is less serious.
Opiate withdrawal is rarely fatal but can be very uncomfortable.
Withdrawal from stimulants like cocaine and amphetamines is rarely fatal but usually results in drowsiness.

Signs and Symptoms of Withdrawal Syndromes

Alcohol withdrawal symptoms can vary from minor shakes to severe conditions involving rapid heart and breathing rates, fever, and excessive sweating. Approximately one quarter of patients may experience hallucinations, with some having brief seizures.

Physical signs of withdrawal from alcohol may feature breathing quickly, a fast heartbeat, tremors, high blood pressure, sweating, or a decreased body temperature. Chronic alcohol consumption can result in physical changes like red, spider-like blood vessels on the skin, flushed facial complexion, weakened eye muscles, poor dental health, head or face injuries from falls, and tongue injuries from seizures during alcohol withdrawal. Other signs of long-term alcohol use include abdominal swelling, an enlarged liver or spleen, and black, tarry stools. Patients with an extended history of alcohol consumption might also have thinning hair, red, spider-like blood vessels on the skin, and breast enlargement in men.

Patients undergoing alcohol withdrawal may have other medical or injury-related conditions that can increase the risk of further health complications or death. Risk factors linked to higher death rates include liver damage due to alcohol, experiencing delirium tremens, the presence of chronic diseases aside from liver disease, and the requirement for a breathing tube.

Withdrawal from sedatives like barbiturates and benzodiazepines can also lead to symptoms like those seen in alcohol withdrawal. Symptoms, typically involving disturbances in bodily functions and movement, usually develop 2 to 10 days after stopping the medication. Gamma Hydroxybutyrate (GHB), a common party drug, can cause withdrawal symptoms that are relatively mild, resembling those of sedative withdrawal, but with potential psychotic symptoms. More severe withdrawal symptoms can occur in long-term users, possibly resulting in seizures and destruction of skeletal muscle.

Opiate withdrawal typically results in mild, non-life threatening symptoms similar to the flu, including excessive yawning, sneezing, runny nose, nausea, diarrhea, vomiting, and dilated pupils. Depending on the specific drug, these symptoms may last from three to ten days. Those who inject drugs are also at risk of infections such as infection of the heart valves, bone infection, skin infection, hepatitis, and blood infection. Opioid users may show signs of a cough, coughing up blood, and rapid breathing due to infections caught from HIV and pneumonia. Users who inject drugs may also have scarring and needle marks.

Withdrawal from central nervous system stimulants like cocaine and amphetamines can also cause symptoms, although these are generally mild and not life-threatening. The individual may experience significant depression, sleep a lot, have an increased appetite, experience unhappiness, and greatly reduced physical and mental activity, but all vital functions are preserved. Recovery is usually slow and depression can last several weeks.

Testing for Withdrawal Syndromes

If you’re showing signs of alcohol withdrawal, your doctor might need to order some tests to figure out the severity of your condition. Here’s what these tests involve and why they’re required:

A glucose test is recommended. This is because long-term alcohol consumption can negatively affect your liver, leading to a decrease in glycogen (a type of sugar that gives your body energy). Alcohol can also interfere with gluconeogenesis, the creation of glucose from non-carbohydrate sources. These issues might lead to low levels of glucose in your blood, causing symptoms like anxiety, tremulousness, seizures, and excessive sweating, all of which are signs of alcohol withdrawal.

An arterial blood gas (ABG) test might also be needed. This can help identify if you’re having mixed acid-base disorders, meaning issues with the balance of acids and bases in your blood. These disorders often occur as a result of alcoholic ketoacidosis, alkalosis caused by fluid loss, and respiratory alkalosis.

A complete blood count (CBC) can show if you have fewer blood cells than normal, an issue that’s common in people who have consumed alcohol for a long time. The test can also show if you have megaloblastic anemia, a condition caused by a deficiency of vitamin B-12 and folate, often seen in long-term alcohol users.

A metabolic panel is beneficial to check for issues like acidosis, dehydration, kidney disease, and other problems common in chronic alcoholics. Certain calculations, such as anion and delta gaps, may be helpful in assessing the type of acid-base imbalance. In individuals with alcoholic liver disease, a low BUN (Blood Urea Nitrogen) value is common. This panel could also examine if there’s an elevated lipase level (suggestive of pancreatitis) or a high blood ammonia level (indicating hepatic encephalopathy, a decline in brain function due to severe liver disease).

Urinalysis is performed to check for presence of ketones (substances your body produces when it burns fat for energy) because you may experience alcoholic ketoacidosis. Rhabdomyolysis, a breakdown of muscle tissue that leads to the release of muscle fibers into the blood, can be suspected if there’s blood in your urine.

Cardiac markers are analyzed to see if you’re at risk of a heart attack or if there’s muscle tissue breakdown from alcohol withdrawal or because of prolonged immobility. Your blood clotting ability can be assessed as well through a prothrombin time test because patients with cirrhosis (scarring of the liver) are at risk for coagulation disorders. The Toxicology screening is done to check for presence of any toxic alcohols or other recreational drugs in your blood that can exacerbate acidity in the body.

Imaging tests such as chest radiography, CT scans of your head, and ECG (Electrocardiogram to check your heart’s rhythm and electrical activity) can help evaluate if there are any complications like aspiration pneumonia, cardiomyopathy, chronic heart failure, bleeding in your skull because of brain shrinkage and coagulation issues, or if there are prolonged QTc interval (a heart rhythm condition that can cause serious irregular heart rhythms). Lumbar puncture is done in order to rule out certain brain infections

Blood cultures may be needed if a blood infection or heart inflammation is suspected.

Treatment Options for Withdrawal Syndromes

When stopping alcohol use, individuals could face life-threatening health problems. If the person develops a seizure, there is a debate over whether intravenous glucose should be given, as it could potentially trigger a condition called Wernicke encephalopathy, often associated with chronic alcoholism. This can be combated by also administering the vitamin thiamine. A class of medications known as benzodiazepines can help control seizures. If blood sugar levels are dangerously low, a concentrated glucose solution may be given along with thiamine. Low doses of a medication called clonidine can help manage symptoms such as rapid breathing, fast heart rate, high blood pressure, tremors, and alcohol craving. For those who are very agitated, an antipsychotic medication called haloperidol may be given as an additional treatment, but care must be taken as it can make seizures more likely and also impact heart rhythm.

Those who use opioids regularly and are trying to quit could experience severe withdrawal symptoms. They may be given a type of medication called buprenorphine, which works in a similar way to opioids but with less effect. This is done to gradually reduce the body’s dependency on the drug. The seriousness of withdrawal symptoms can be evaluated using the Clinical Opiate Withdrawal Scale (COWS). This scale is a set of criteria used to identify withdrawal symptoms and monitor how well treatment is working. Other medication such as methadone (which works like an opioid), clonidine (which can help ease symptoms), and long-acting benzodiazepines (which can help manage inability to sleep and muscle cramping) might also be used.

Withdrawal from a class of drugs known as sedative-hypnotics can be helped by replacing them with long-acting drugs such as benzodiazepines or phenobarbital. These are then gradually reduced over 2 to 3 weeks.

Withdrawal from a substance known as GHB can be treated with high doses of benzodiazepines. If that doesn’t work, drugs like pentobarbital, chloral hydrate, and baclofen might be used.

For those withdrawing from stimulants, the recommended treatment is primarily observation.

If you’re experiencing certain symptoms, it could be due to various conditions. Here are some possibilities:

Acute coronary syndromes (conditions that cause sudden, reduced blood flow to the heart)
Acute hypoglycemia (low blood sugar)
Anticholinergic toxicity (poisoning due to certain medications or substances)
Anxiety disorder
CNS disorder (a problem with your brain or nervous system)
Cocaine toxicity (poisoning from cocaine use)
Delirium Tremens (severe alcohol withdrawal symptoms)
Dementia
Depression
Suicide

Remember, if you’re feeling unwell, it’s essential to reach out to a healthcare professional for advice and potential diagnosis.

Withdrawal syndromes are a widespread health issue.

Withdrawal syndromes are treated using various medications depending on the specific substance being withdrawn from. For alcohol withdrawal, benzodiazepines, thiamine, and glucose solutions may be used to manage symptoms such as seizures, rapid breathing, and high blood pressure. Opioid withdrawal can be treated with medications like buprenorphine, methadone, clonidine, and long-acting benzodiazepines to gradually reduce dependency and manage symptoms. Sedative-hypnotic withdrawal can be helped by replacing them with long-acting drugs like benzodiazepines or phenobarbital. GHB withdrawal can be treated with high doses of benzodiazepines, and if that doesn't work, drugs like pentobarbital, chloral hydrate, and baclofen might be used. Stimulant withdrawal primarily requires observation.

Withdrawal syndromes are the symptoms that people experience when they stop taking drugs or alcohol after prolonged use. The severity and duration of these symptoms vary depending on the length and amount of substance use.
