@CeeBee1807 Forgive the brevity of this post CeeBee as I cannot write a lengthier reply just now, but I have just read your post and wanted to say I think you are onto something.  Do mention to your GP that you already have a relative with coeliac disease. Do also take a look at the Coeliac UK website before you see the doctor, they have a whole section on  how to get diagnosed in the UK.  

Hi, @Eldene, Make sure you're getting sufficient Omega Three fats which will help with satiety.  Omega Threes vegetarian sources are Chia seeds, flaxseed, and walnuts.   What are the ingredients in your protein smoothie? What do you normally include in your "plant-based healthy meals, with enough protein"?

I might suggest taking a bullet list with you to your next appointment with concisely worded symptoms and test requests. That would cut to the chase and economize the time you do have with the doc.

Thank you, I will have a read through through this.    No not insulted at all, you are completely correct.  It has always been this way to an extent with regards to reluctance in ordering further tests, but with current pressures it seems more difficult than ever. There are not enough GP appointments and I’m aware they are seeing more patients than ever. It’s difficult to explain all symptoms and go through history in 10 minutes, so I can see why we are where we are but, equally frustrating as I believe delving a little deeper could have possibly helped, a lot sooner.    I really appreciate all the information on which tests I should be asking for, I think it won’t be as easy to brush me off if I’m confident in what I’m asking for. Hopefully I get a positive response. 

Sorry....I realized I did it wrong after hitting submit...and I ressubmitted to Knitty.  Getting used to this interface....but thanks for the followup.  You've built a nice community here.  I've gotten more useful information in 24 hrs for free than I have in the past 12 mos for thousands of dollars. Now I'm hopeful some of it helps me   TV
