Hi Shirley! thx for your response!
i did think about a possible infection, similar to traveler's diarrhea…but those usually resolve in 2 weeks or so and mine had been going on 3 weeks+. also, later i realized that the diarrhea was a hyperthyroid symptom of mine. when i finally got diagnosed and started on PTU, my symptoms would improve but symptoms like palpitations and esp the diarrhea, would come back about 6-7 hours after my last PTU dose. the hyperthyroidism was “breaking through” my PTU dose so my doctor shortened the interval of my dose while also increasing the dose, so instead of twice a day it was changed to 3x/day.
so, those breakthrough symptoms got me thinking about the diarrhea i had after the cruise….I was just thinking that the inadvertent increased iodine consumption during the trip may have caused/allowed my body to make more thyroxine hormone resulting in me becoming more hyperthyroid, resulting in more hyperthyroid symptoms like diarrhea, increased frequency of stool, etc. of course, i could have just developed the diarrhea anyways from the then undiagnosed graves' disease taking it's natural course and it was just coincidental that i went on a cruise when my symptoms got worse. but looking back, i had symptoms for quite some time, 6 months or so, but they got significantly worse or enhanced after the cruise. for example, i had also lost most of my weight in the 2 months after the cruise, when prior to the cruise, i had just lost a little bit over the previous 6 months.
I am seeing an endocrinologist and I'm on propranolol 10mg 3x/day, as well as PTU. i am not one to think that diet alone could change anything. that i know would be dangerous. my doctor did tell me that a low iodine diet would help me; she initiated this info herself; mostly saying to avoid seafood and seaweed. and this recommendation was knowing she was NOT going to order any uptake scan on me (because she didn't feel it was necessary because she didn't feel any nodules in my neck). i know a LID (low iodine diet) is usually recommended especially in the weeks before an uptake scan is done.
it's just that, fish is kind of hard to avoid because my husband is eating it almost every other day to improve his good cholesterol (HDL). i don't want to have a no iodine diet or really even a very low iodine diet….i'm just not sure if having fish 3-4x / week would increase the iodine in my diet way more than i should given that i have graves'….so that's why i was thinking that a low-iodine diet to compensate for the high amount of iodine i was getting in the fish would even things out in any way. i don't want to sabotage my husband's diet and he doesn't want to sabotage mine, so i'm trying to find something that can help the both of us. i'm getting sick of just chicken.
husband is having limited red meat at this time to reduce his cholesterol.
anyways, i did think about us both seeing a dietician together. that's probably the way to go. i'll let everyone know what he/she says. in the meantime, any other suggestions/ideas out there about fishes low in iodine but ample in omega-3 fatty acids?
