I started having symptoms of diabetes in 2004. Had been on steroids because of a wasp sting and anaphylactic shock for some time and when I was on these I put on quite a bit of weight as you do. Then I stopped them. Then I started losing, and losing …, had the tiredness, blurred vision, thirst etc but nobody picked it up! I went from 14 stones to 5 1/2 very rapidly and looked like someone coming from a concentration camp! I was breathless, my legs were heavy etc. (Now I know I was full of ketones!)
I had to go into hospital for severe, and I mean severe stomach pains - which turned out to be due to a tumour on my pancreas which thankfully was benign but was pressing on the bottom of my stomach and pushing it up through a hole in my diaphragm. They also found another on my pancreas - which thinking back I had known about for years but had not given it much thought. Pre-diabetes I had had exceptionally low blood sugars and in England they would not investigate so I went home to Latvia (then still under communism and the hospitals were dire) and was found to have this benign tumour and “enlarged spleen”.
Well, I had pioneering surgery on my spleen tumour - I was the first in the world to be treated in the way that I was - first time without anaesthetic which was extremely painful. Second time they put me out. It was a success and though it took some weeks to recover in hospital, it was wonderful to be pain free for a while! They could not reach the pancreas tumour because it is situated behind my liver and they would have had to go through that - causing possible fatal bleeding.
I was restless sometimes while in hospital (total 8 weeks) and would go for a walk. It was at 3 am one morning that they asked me if I needed help for my “problem”. I asked what problem and they said your drink problem. Whaat??? I had just had abdominal surgery, the nearest shop that would sell alcohol was 1 1/2 miles away, I was on a drip, it was 3 am and the only person I saw was a porter taking a body to the morgue - where was I going to get alcohol from? And why?
I remained in the hospital as I said for 8 weeks - totally missed Easter and spring that year! They were about to let me out when they decided to do another blood test (one of hundreds!). The next day they came to me and said that I was Type 2 diabetic (WROOOONG!!) and I swore (which I do not usually do!) as I am totally phobic about needles and the thought of sticking needles in myself was (still is) abhorrent. I was kept in another 2 weeks and then sent home with tablets.
My general doctor was sympathetic but has never discussed diabetes with me. She sees me coming into the surgery and says “I am not discussing diabetes. I hope there is something else wrong!”
I had two cases of DKA ending in hospital (again with accusations of having had too much to drink! - interesting that, my poison of choice would have been vodka which has no smell!). On the second of those occassions the doctors in the hospital asked me why I had not been taking my insulin? Er, because it has not been prescribed and I am Type 2. He said that I was definitely type 1 and should be using insulin. They gave me insulin on a drip and left me - and I went hypo!! First indication that human insulin does not cut it with me!
Looking at your description - about the loss of taste etc, perhaps yours was triggered by a cold or virus.
