I let these symptoms (hair loss, weight gain, premature graying hair, loss of lower 1/3 of eyebrow hairs, sensitivity to
cold and depression, irritability, memory loss) go unchecked for 2 years. I was then diagnosed with hashimotos thyroiditis and have spent the last year getting regulated with just t4. I still did not feel like myself a month before finally being regulated so i was put on anti-depressants and had blood drawn to test for anything else that might be wrong with me.
