Complications:

Alcohol depresses your central nervous system. In some people, the initial reaction may be stimulation. But as you continue to drink, you become sedated.

Too much alcohol affects your speech, muscle coordination and vital centers of your brain. A heavy drinking binge may even cause a life-threatening coma or death. This is of particular concern when you’re taking certain medications that also depress the brain’s function

Impacts on your safety:

Excessive drinking can reduce your judgment skills and lower inhibitions, leading to poor choices and dangerous situations or behaviors, including:

• Motor vehicle accidents and other types of accidental injury, such as drowning
• Relationship problems
• Poor performance at work or school
• Increased likelihood of committing violent crimes or being the victim of a crime
• Legal problems or problems with employment or finances
• Problems with other substance use
• Engaging in risky, unprotected sex, or becoming the victim of sexual abuse or date rape
• Increased risk of attempted or completed suicide

Drinking too much alcohol on a single occasion or over time impacts health problems:

• Liver disease. Heavy drinking can cause increased fat in the liver (hepatic steatosis), inflammation of the liver (alcoholic hepatitis), and over time, irreversible destruction and scarring of liver tissue (cirrhosis).
• Digestive problems. Heavy drinking can result in inflammation of the stomach lining (gastritis), as well as stomach and esophageal ulcers. It also can interfere with absorption of B vitamins and other nutrients. Heavy drinking can damage your pancreas or lead to inflammation of the pancreas (pancreatitis).
• Heart problems. Excessive drinking can lead to high blood pressure and increases your risk of an enlarged heart, heart failure or stroke. Even a single binge can cause a serious heart arrhythmia called atrial fibrillation.
• Diabetes complications. Alcohol interferes with the release of glucose from your liver and can increase the risk of low blood sugar (hypoglycemia). This is dangerous if you have diabetes and are already taking insulin to lower your blood sugar level.
• Sexual function and menstruation issues. Excessive drinking can cause erectile dysfunction in men. In women, it can interrupt menstruation.
• Eye problems. Over time, heavy drinking can cause involuntary rapid eye movement (nystagmus) as well as weakness and paralysis of your eye muscles due to a deficiency of vitamin B-1 (thiamine). A thiamine deficiency also can be associated with other brain changes, such as irreversible dementia, if not promptly treated.
• Birth defects. Alcohol use during pregnancy may cause miscarriage. It also may cause fetal alcohol syndrome, resulting in giving birth to a child who has physical and developmental problems that last a lifetime.
• Bone damage. Alcohol may interfere with the production of new bone. This bone loss can lead to thinning bones (osteoporosis) and an increased risk of fractures. Alcohol can also damage bone marrow, which makes blood cells. This can cause a low platelet count, which may result in bruising and bleeding.
• Neurological complications. Excessive drinking can affect your nervous system, causing numbness and pain in your hands and feet, disordered thinking, dementia, and short-term memory loss.
• Weakened immune system. Excessive alcohol use can make it harder for your body to resist disease, increasing your risk of various illnesses, especially pneumonia.
• Increased risk of cancer. Long-term excessive alcohol use has been linked to a higher risk of many cancers, including mouth, throat, liver, colon and breast cancer. Even moderate drinking can increase the risk of breast cancer.
• Medication and alcohol interactions. Some medications interact with alcohol, increasing its toxic effects. Drinking while taking these medications can either increase or decrease their effectiveness, or make them dangerous.What to expect to report to your doctor.Before your appointment, make a list of: Consider your drinking habits, taking an honest look at how often and how much you drink.

Alcohol can damages our cells and this can stop cells repairing damage.  Alcohol effects chemical signals which can make cells more likely to divide this in turn increases the chance of cancer to develop.  Alcohol makes it easier for cell in our mouth and throat to absorb cancer causing chemicals.

There are many ways that alcohol can cause cancer. Some of the main ways are:

• Damage to cells. When we drink alcohol, our bodies turn it into a chemical, called acetaldehyde. Acetaldehyde can damage our cells and can also stop cells from repairing this damage.
• Changes to hormones. Alcohol can increase the levels of some hormones in our bodies such as oestrogen and insulin. Hormones are chemical messengers, and higher levels of oestrogen and insulin can make cells divide more often. This increases the chance that cancer will develop.
• Changes to cells in the mouth and throat. Alcohol can make it easier for cells in the mouth and throat to absorb harmful chemicals that cause damage.

Remember, it’s the alcohol itself that damages your body, even small amounts. It doesn’t matter whether you drink beer, wine or spirits. All types of alcohol can cause cancer.

There’s plenty of tricks that people claim ‘cure’ hangovers. But even if they work for your hangover, they don’t reverse the damage caused from drinking alcohol.

Treatments for alcoholism disorder may include:

• First know treatment for alcohol use disorder can vary, depending on your needs. Treatment may involve a brief intervention, individual or group counseling, an outpatient program, or a residential inpatient stay.

Treatment may begin with a program of detoxification or detox — withdrawal that’s medically managed — which generally takes two to seven days. You may need to take sedating medications to prevent withdrawal symptoms. Detox is usually done at an inpatient treatment center or a hospital.  Learning skills and establishing a treatment plan.

You may benefit from couples or family therapy — family support can be an important part of the recovery process.
• Oral medications. A drug called disulfiram (Antabuse) may help to prevent you from drinking, although it won’t cure alcohol use disorder or remove the compulsion to drink. If you drink alcohol, the drug produces a physical reaction that may include flushing, nausea, vomiting and headaches. Naltrexone (Revia), a drug that blocks the good feelings alcohol causes, may prevent heavy drinking and reduce the urge to drink. Acamprosate (Campral) may help you combat alcohol cravings once you stop drinking. Unlike disulfiram, naltrexone and acamprosate don’t make you feel sick after taking a drink.
• Injected medication. Vivitrol, a version of the drug naltrexone, is injected once a month by a health care professional. Although similar medication can be taken in pill form, the injectable version of the drug may be easier for people recovering from alcohol use disorder to use consistently.
