When Crystel Clarke-Lezama was diagnosed with hyperthyroidism in 2018, she had a choice to make. She could let the disease run her life or take action by advocating for early intervention.
An educator and mother of two, she wrote Thyro and Thyra—The Thyroid Twins. The interactive storybook follows two lively siblings as they deal with school, sports and doctor visits while finding ways to keep their faith and prioritise their well-being.
It teaches young readers how a small gland in the body can affect how they feel and grow. Thyro demonstrates an overactive thyroid, while Thyra has an underactive one.
“I wanted to make the story relatable,” says the Cumana Village, Toco, native. “It’s targeted towards children from Standard Three to Five, as well as Forms One and Two. It was important to show the characters in everyday settings because that is where little ones learn best. They see that kids facing health hurdles can still be active, energetic, and thrive.”
Crystel’s symptoms included swollen feet and neck, anxiety, stress, lack of sleep, brittle nails, feeling cold when others were hot, and depression. Someone close to her noticed she wasn’t herself and advised her to seek urgent medical attention. That step saved her life.
“I went and did a blood test, and I finally got the answer that I had hyperthyroidism,” she tells We Life and Culture. “After recovering, I still have to monitor my blood every month. Readers should know that if they experience any one of these symptoms, please don’t diagnose themselves—they should get checked out.”
Thyroid education is personal to the Cumana Seventh-day Adventist teacher, but she also believes the health issue isn’t spoken about nearly enough here at home.
“Without medical support and a change in diet, it can get out of hand and even become life-threatening. I do not want any child or parent to go through what I did, so I want people not to wait to seek care.”
Because thyroid disorders can run in families, Crystel, 34, has been open about the condition with her own children, aged four years and five months. She teaches them to listen to their bodies, manage emotional tension and speak up when something feels unusual.
Studies indicate that up to 60 per cent of those living with thyroid conditions remain undiagnosed. Treating the disorder as an invisible illness, she focuses on proper nutrition and physical activity.
Since the book, which took her about five years to write, was published, the Bates Memorial High and University of the Southern Caribbean graduate says parents, teachers, young people and even strangers have been reaching out to share their own journeys.
“I am also receiving many requests to bring Thyro and Thyra to schools for readings. Many people ask what I did to manage it. I tell them that I overhauled my lifestyle, kept my medical appointments, and trusted in God.”
Copies of Thyro and Thyra—The Thyroid Twins are available at select bookstores and directly from Crystel. Her next plan is to host an official book launch with local screenings in January and maintain momentum by visiting communities and health facilities to highlight the importance of early detection and how food impacts overall health.
“It was really through my sickness that I decided I should write this book,” she says. “I said that if God can bring me through this, He certainly can for anyone else. My goal is to keep the conversation going so people can be informed before it’s too late.”
Sidebar: Understanding thyroid health
What is the thyroid gland? The thyroid is a small, butterfly-shaped organ located at the base of the neck that produces hormones controlling metabolism, heart rate, body temperature and overall growth.
Hyperthyroidism vs hypothyroidism:
Hyperthyroidism (represented by Thyro): An overactive thyroid gland that produces excessive hormone levels, accelerating the body’s metabolism.
Hypothyroidism (represented by Thyra): An underactive thyroid gland that produces insufficient hormone levels, slowing normal body functions.
Key facts:
Women are five to eight times more likely than men to develop a thyroid condition during their lifetime.
A routine TSH (thyroid-stimulating hormone) blood test is a primary diagnostic tool used to assess how well the gland is functioning.
