My clinic experience shows that hypothyroidism has a direct relation with diet.
The first thing I do is to correct the patients diet to allow easier digestion and therefore give a “rest” to their bodies. I also prescribe some supplements and acupuncture, of course.
But I believe that each individual must have his personal diet. Not one that is just best for his metabolism, but also one that fits his routine and pockets. But the basic recommendation is to remove gluten, dairy and all the junk food during the treatment.
The basic supplementation for thyroid is iodine and usually it does all the job.
Another usual problem for hypothyroidism is the lack of Vitamin D. I recommend daily sun baths, but of course, you can use pills. Best with Vitamin K2, never with Calcium.
As for the acu points, I’d use moxa at Ren Mai 4, Stomach 36 and Spleen 3. And needle at Stomach 9 and Ren Mai 22.
