Hi – so glad you’re here with us too! Ok, there’s a lot to unpack here as there can be many possible contributing factors, but I will do my best to offer some guidance and clarifying questions to hopefully give you some direction.
Dark circles under the eyes could point to food sensitivities/allergies (here is the handout in Resources, especially since you’ve struggle with that symptom since childhood. Have you tried an elimination diet before? Dairy and gluten are very often culprit foods so you can look at the dairy and gluten elimination handouts for more details on all the types to remove initially.
Dark circles could also point to issues with liver detoxification or kidney dysfunction. Have you seen a doctor to run some tests?
There is a possibility that your thyroid medication may be contributing to your loose stools. TSH alone is not enough to indicate whether or not there is optimal thyroid function. If your stools are more loose, your medication may need to be adjusted. Loose stool however, could also be due to dysbiosis or some form of gut overgrowth. The Gut Health Masterclass will help troubleshoot with this, if that’s a contributing factor.
You mention not feeling good. What symptoms are you referring to exactly?
