HI, thanks for using healthcare magic
There are a number of hormones that are elevated in pregnancy
and also other changes that could impact on the severity of ulcerative colitis
In terms of HCG
specifically, there are not enough medical research studies to determine the effect of this diet on your condition.
It would be best to speak to both your doctor and a nutritionist to determine if it is likely to aggravate the ulcerative colitis.
I hope this helps
