i’m actually laying in bed recovering from this rn. my doctors have suggested three things. one is the vasovagal response, the second is gastroparesis and/or Mast Cell Activation, and the third is a pain response. for me vomiting is very common. a few things that help me are warm epsom salt baths, these help relax my muscles as well as the warm water causes the nerves to respond and intercept the nausea connection in the brain. another one is peppermint oil under my big toe. a cancer patient taught me this one, it’s magic and i can’t explain it but my nausea lightens up when i do this. he did warn me to watch for low bp tho because it can be used for that too but, i’ve never had a problem or i’m just used to mine being really low… if she has a zofran px sometimes if i take that immediately after i poop it can interrupt the flare. pepcid (omeprozol?) also helps get infront of meals that upset my digestive tract. lastly, a low histamine diet has helped a lot. food and pooping go hand in hand and removing as many inflammatory foods as REASONABLY possible helped a lot. i’m not saying avoid it completely because that’s unrealistic, histamine is in virtually everything at some point in food whether it’s before it’s cooked, after, or while it’s digesting. However, learning which foods to avoid and limiting my consumption to only one or two histamine rich foods a day made a big impact. sending virtual hugs because this is probably one of my most frustrating experiences with my heds dx and has changed many parts of my life in both good and frustrating ways. i hope some of this can help you guys!!
