As requested.
Every time your liver has to filter alcohol, some liver cells die. Most people are aware that the liver is regenerative but that is only to a certain extent and certainly not in the context of prolonged alcohol excess (over the recommended units per week for a significant length of time).
Eventually your liver becomes damaged and scarred - causing cirrhosis and associated complications. Liver disease and cirrhosis often don’t show signs or symptoms until very late stage - definitely too late to reverse any damage already done.
Complications of liver disease include oesophageal varices - effectively varicose veins in the gullet. The liver is responsible for producing many of your blood clotting factors. These varices can go undetected for a long period of time and then suddenly rupture. Your blood then does not clot correctly due to the liver damage and I have watched patients bleed to death in a matter of minutes due to enormous variceal haemorrhage.
Other complications of liver disease include ascites - the build up of fluid in the abdomen. People end up looking 9 months pregnant due to the sheer volume of fluid in their abdomens. This is painful and compresses the other organs, causing breathing difficulties and mobility issues. This symptom is often recurrent and people require repeated abdominal drains. This fluid often gets infected (spontaneous bacterial peritonitis) and people die from this or from infections caused by repeated drains.
Toxins can build up in the brain due to liver damage causing a condition called encephalopathy - extremely sudden onset acute confusion. I have seen patients violently attack their families due to this confusion and cared for patients who are comatose due to this build up of toxins - it can cause death if not responsive to treatment.
I have cared for people who were admitted with sudden onset alcoholic hepatitis after a drinking episode that was more than their ‘usual’. People who had no signs of liver disease beforehand - suddenly acutely unwell and needing a lifesaving liver transplant which they ultimately never receive because as someone who drinks excessively, they are the bottom of the transplant list and almost always die before a new liver is found. Most transplant lists require a 6 month period alcohol abstinence before you can even be listed for a transplant.
I have watched people in their late 40s admitted with sudden onset symptoms who are so acutely unwell that they die a couple of weeks later in hospital with their children and spouses in such emotional distress because they did not think that their family members drinking was a concern.
Posters saying that OP should just ‘carry on if they enjoy it’ are absolutely deluded to think that this level of drinking can be maintained indefinitely with no consequences.
