Ive developed thyroid post delivery, are there any chances for it to get cured?

I developed hypothyroidism after my pregnancy and have been struggling with it ever since. I was initially put on medication (Thyroid hormone replacement therapy) for three months and then it was stopped for testing. However, My tests were positive and I had to continue with medication. What has helped keep it in check is Yoga, especially the Ujjayi pranayam). You can see a video here: https://youtu.be/BUJOxuj4MXU Also there are recommended diets and avoidance of certain food as well. I am part of the Thyroid support group in Singapore and there is a lot of useful information on there. https://www.facebook.com/Thyroid-Support-Singapore-823698641043965/
