"unable to eat without vomiting, left for 8 weeks with little treatment and no cause"

So my partner and I found out we were expecting a baby, we couldn't really celebrate the exciting news because my partner had been unwell for few days and still was unwell, everything he ate, he brought back up within 20mins, fruit, fish, meat and I'm a chef myself so I arranged his diet, was a good healthy diet, so it got on top of him one night and we went to a&e.

They took some blood, and he was diagnosed with diabetes, still unsure which one it is though, so we went to speak to a diet expert, and they assumed that his sugar levels and keytone levels were the cause of the vomiting! He was send home with some medication and told to keep testing his levels, 2 weeks after, still unable to eat a thing back in a&e were they did a liver scan to find he had fatty liver disease.

He was admitted to hospital to be placed on a drip as he was very unwell and had no energy, they suspected gallstones but maybe a stomach ulcer, a scope was arranged - being told he would be sedated before he didn't panic, but when it came to the scope they didn't intend to sedate him and he panicked, so they were unable to do the scope and three days later there was talk about a different kind of test, a stool sample, but he couldn't as he had diarrhoea , he was in a total of 9 days and nothing productive was done!

He was then discharged with more tablets and to wait for 8 weeks and come off the tablets for a stool sample - he is still unable to eat without vomiting and the doctors say more test but we are due our baby in 5 month so we feel that the hospital have done nothing but hope for the best and now we have a baby due and he had no energy, sleeps most of the day and the doctor attitude is well we can't force him to eat!

We will be going to the southern general hospital in the hope they can be more help full that the royal Alexander hospital in paisley! !
