OP: My Mum is a recovering alcoholic. Much like your Dad, she was having falls. After a couple of years, her blood levels were through the floor. I think her haemaglobin level was about 5.5 or something. She was thiamin deficient too. She was fobbing my brother, sister and I off with different stories, so my sister rang my Mum's GP. It turned out that my Mum's GP (who is my GP also) was also very worried about my Mum. My Mum at this stage had had a second bad fall.
My Mum got taken to hospital where she partially dried out as the consultant ignored the liver and concentrated on diverticulitis. Mum was discharged and drank again to a lesser extent. She had another fall where she fell down the stairs, banged her head on a radiator and lay there for about 9 hours.
My sister found her and got her taken to hospital again. This time, they took us seriously and listened to us telling them about her drinking. She had a blood transfusion, a saline drip, a calcium drip (to counteract high potassium levels), had the ascites drained off from her abdomen and was put on high vitamin B shots.
She was told that if she didn't stop drinking, she would be dead quite soon. In fact, she was given 6 months to live in March last year. She has had intensive counselling and has carers going in twice a day (set up by the council through the hospital).
We have prepared ourselves for the worst, but hoped for the best. Mum has made it through Christmas, which is better than predicted, but it is one day at a time. She's an adult and as such, has the choice to look after herself or not.
The ripples run wide. At the end of the day, you can only do so much and then your little family comes first before someone else.
