50% Weight Loss

Today I discovered sadly that yet again I have lost more weight and that my weight loss has now tipped over to 50% total weight loss since October 2019 (when I first got pregnant).
During the hyperemesis I lost 108lbs in weight (7 stone 10lbs) and went from BMI of Obese (41) to Normal (22).
Since pregnancy ended my vomiting continued and I likely have gastroparesis (still awaiting final diagnosis to confirm). I have daily vomiting but just not to the extent that I did during HG. Now it is mostly related to food unless I’m in a flare up. Its been so hard to keep my weight stable, I tend to lose a little, get prescribed extra supplements and then put on a few pounds again and I yoyo. Normally my weight is 133lbs but can go up or down by about 4lbs. However my symptoms have been particularly bad this month and my weight has steadily gone down and I am now 120lbs which is my lowest ever!
Since pregnancy ended in June 2020 I have lost nearly 10% of my weight to this new sickness condition, which is quite a concern as my doctors are not wanting me to lose anymore. But it does mean that since October 2019 I have lost a total of 50.21% of my original body weight to sickness.

I have a Gastric Emptying Scan later this week which I am hoping will finally confirm my diagnosis, though doctors are 99% certain I have gastroparesis after a gastroscopy showed food debris in my stomach 13 hours after fasting, showing a definite motility problem. Once I have my diagnosis I am hoping there will be a treatment or surgery they can give me to help get this vomiting under control so that I can finally have a normal quality of life and actually keep a meal down.
