Gut, stress, sleep & the myths

The gut-thyroid link is real, but the concrete, evidence-based version isn't a 'leaky gut protocol' — it's finding and treating an actual condition. Screen once for celiac; test and treat H. pylori or SIBO if you have symptoms. Probiotics and fibre help gut comfort and quality of life but don't move your thyroid numbers — worth it for symptoms, not as thyroid treatment. Evidence ●●●○○ (celiac screening ●●●●●)

Chronic stress genuinely modulates autoimmunity, and stress reduction (mindfulness, yoga, breathwork) reliably improves symptoms and quality of life — do it. But 'adrenal fatigue' is not a recognised diagnosis, and its saliva-cortisol panels and adrenal supplements aren't validated (they can even mask the real cause — under-treated thyroid, sleep apnoea, depression). And fix sleep: hypothyroidism and poor sleep feed each other, so if you snore or stay exhausted despite a normal TSH, get screened for sleep apnoea. Evidence ●●●○○

A curiosity: smoking oddly associates with lower Hashimoto's risk — but it harms you overall and worsens the related Graves' disease, so still quit (just get your thyroid checked afterward, as risk briefly rises). And a hard truth about weight: hypothyroidism causes only modest gain (much of it water), and treatment doesn't melt it off — never push your dose into the hyperthyroid range to lose weight (it risks your heart and bones and doesn't work). The real levers are the ordinary ones. Evidence ●●●○○
