yuuichi Posted February 12, 2019 Not literally of course, but I am diagnosed to have a kidney yin deficiency. For all my life, I have always: Woken up each morning thirsty or with a dry mouth, Sleep late or have trouble sleeping, I have a lot of trouble gaining weight (I am tall and thin), My tongue has always been red. Â However, these are also the symptoms of hyperthyroidism (overactive thyroid). Â I had my thyroid tested 2 years ago, and 2 years before that, because thyroid problems run in the family. But my thyroid has always been fine. But I display all the symptoms of an overactive thyroid so a lot of people always ask me to get my thyroid checked. 1 Share this post Link to post Share on other sites
