I had a gastric sleeve and had no problems with the surgery.
During the liquid/mushy stage, I developed a dislike of liquids because everything tasted so sweet and water left a disgusting taste in my mouth so I became a little dehydrated. After speaking to the bariatric nurse, who thought I might have oral thrush, I got some medication from my GP. It took a few weeks but the symptoms improved and the 'incredibly sweet' taste eased off.
I then developed a problem with dairy. Milk, cheese and eggs were a problem for me and still are.
I also started vomiting after food and regurged a lot as well. I had to have two barium swallow tests and also two endoscopys and it was discovered that I had a tight sleeve, a narrowing of the food pipe and also a clockwise twist of the food pipe.
As time went on, the sickness and regurging drastically improved and I can now eat a little more than before.
There are a lot of foods that I can only tolerate in very small doses or not at all like bread, rice, dry meat, chips and bacon.
I am experiencing very nasty stomach aches at the moment and I'm waiting for further tests. It could be my food pipe or gall stones which I know I have because I was diagnosed with them in March, but I think it's down to me eating too much without letting the previous food digest (head hunger problem).
Having said all this, I wouldn't change my sleeve for anything and don't regret it for a minute. I'm currently a size 16 top and a 14/16 bottom. The last time I was a size 14 was 29 years ago!
My weight loss has now completely removed the threat of diabetes (had a blood test to confirm this). I can also walk a lot faster than before and for a much greater distance. I can also run and I'm thinking of taking up jogging. I've lost muscle tone, especially in my arms and bottom so I will have to work on that but generally, I feel a lot healthier.
