MANILA -- Michelle Madrigal is on a journey of "healing naturally" after she was recently diagnosed with Hashimoto's disease, the former Kapamilya actress revealed Thursday.

On Instagram, the 29-year-old actress explained to her followers the illness she has to battle, "along with other millions of young and older women who suffer from it."

She wrote: "It is an autoimmune disorder that can cause hypothyroidism, or underactive thyroid. It means that my immune system makes antibodies that attack the thyroid gland. The thyroid becomes damaged and can't make enough thyroid hormones."

Madrigal also shared that she has developed goiter or an enlarged thyroid, noting that thyroid hormones "control how our body uses energy, so they affect nearly every organ in your body."

The fitness enthusiast, however, appears to be optimistic about her case as she detailed how she systematically plans to overcome her illness, "in a holistic way."

Pointing out she has yet to be prescribed any medication, Madrigal said she has been looking into AIP or autoimmune diet, as well as paleo diet. "I started cutting sugar and gluten into my diet and it is amazing that I am not really craving sweets lately," she added.

Madrigal, a first-time mom who gave birth just last October, did not discount other challenges that may come up along the way, saying that aside from healing, there are also "daily stress and emotional flare ups" to deal with.

"I really am on a huge 'transition phase' of my life this year. So here's to healing naturally and being healthy from the inside out!" she concluded, with hashtag a that reflect her goal and minset -- #healthyfromtheinsideout.
