My dad has hashimotos disease. He's been on thyroxin for over 20 years now. Thyroxine is no longer working at a safe level. The Drs won't raise the dosage because of the impact it's having on his heart. My dad has recently retired and has become very poorly again, like before he was on thyroxin.
Are there any other options? Any foods, natural products that can help him as at the moment he's just asleep all the time and in pain 😞. He's only 66 and pretty fit.
