Your thyroid is one of the most essential and often overlooked organs in your body. Located at the base of your neck, the butterfly-shaped thyroid is part of the endocrine system. Thyroid function in the endocrine system is essential for regulating hormones that support various vital bodily functions. It consists of the pituitary gland, thyroid, pancreas, and more.
To gain a deeper understanding of this remarkable organ, it's important to explore thyroid function, how to take care of the thyroid, and common issues that may arise.
What Does The Thyroid Do?
The thyroid gland works by producing hormones throughout the day that affect nearly every cell in the body. These hormones produced in the thyroid regulate the following:
- Metabolism: The thyroid controls how quickly your body converts food into energy. An underactive thyroid slows metabolism, while an overactive thyroid speeds it up.
- Heart Rate: Thyroid hormones help regulate your heartbeat and blood pressure.
- Body Temperature: They help maintain a steady body temperature.
- Menstrual Health: Imbalances in thyroid hormones can lead to irregular periods, heavy flows, or even fertility issues.
- Mood and Brain Function: The thyroid influences cognitive function, mood stability, and mental clarity.1
So, next time you think of who has always been there for you–consider your thyroid. It’s been working with the rest of your body around the clock to keep your daily functions regulated.
Common Thyroid Issues and What to Do About Them
Sometimes our thyroid is not performing optimally. When discussing thyroid disorders, it's essential to understand hypothyroidism vs. hyperthyroidism, as they have opposite effects on metabolism. Here are some early warning signs of thyroid problems and what to do about them.
Hypothyroidism (Underactive Thyroid)
Hypothyroidism occurs when the thyroid doesn’t produce enough hormones, slowing bodily functions. It can be caused by Hashimoto’s thyroiditis, an autoimmune disorder in which the immune system attacks the thyroid.
Symptoms of Hypothyroidism2 :
- Fatigue and sluggishness
- Unexplained weight gain
- Cold intolerance
- Dry skin
- Hair thinning or loss
- Depression
- Constipation
- Irregular or heavy periods
Hypothyroidism is typically managed with thyroid hormone replacement therapy.2
Hyperthyroidism (Overactive Thyroid)
Hyperthyroidism occurs when the thyroid produces too many hormones, speeding up bodily functions. It can be caused by Graves’ disease, another autoimmune condition.
Symptoms of Hyperthyroidism:
- Unexplained weight loss
- Rapid or irregular heartbeat
- Anxiety and irritability
- Excessive sweating and heat intolerance
- Frequent bowel movements
- Tremors (shaking hands or fingers)
- Lighter or infrequent periods3
Options for hyperthyroidism include anti-thyroid medications, radioactive iodine therapy, or, in some cases, thyroid surgery.4
3. Thyroid Cancer
Though less common, thyroid cancer symptoms can include:5
- A lump or swelling in the neck
- Hoarseness or voice changes
- Difficulty swallowing
- Persistent throat or neck pain
A thyroid ultrasound is often used to detect abnormalities and assess potential thyroid cancer risks.6
Prioritizing Thyroid Health
Keeping your thyroid healthy naturally involves a combination of diet, lifestyle choices, and medical awareness—although there is no one-size-fits-all plan. Some women spend decades finding what works best for them, but here are some of our go-to ways to support the thyroid:
1. Eat a Thyroid-Friendly Diet
Your thyroid relies on key nutrients to function properly. Make sure you’re getting enough:
- Iodine: Found in iodized salt, seaweed, fish, and dairy.
- Selenium: Found in Brazil nuts, sunflower seeds, and eggs.7
- Zinc: Found in shellfish, beef, and legumes.8
- Vitamin D: Essential for immune and thyroid health. Get it from sunlight or supplements.9
Some people limit excessive consumption of goitrogens, naturally occurring compounds found in cruciferous vegetables (like broccoli and cabbage) that can stunt the absorption of iodine, as well as soy, pearl millet, and cassava.10
While diet and lifestyle are the foundation of thyroid health, targeted nutritional support can be beneficial. FLO Endocrine Superfood Powder is designed to support hormonal balance with essential vitamins, minerals, and adaptogens that promote optimal endocrine function.* As always, we recommend speaking with your healthcare provider before integrating any new supplements into your routine.
2. Manage Stress
Chronic stress can take a toll on the thyroid. The adrenal glands, which regulate stress hormones, work closely with the thyroid. When you’re stressed for long periods, it can throw both systems out of balance.11
Ways to Reduce Stress:
- Practice meditation, deep breathing, or yoga.
- Get enough sleep.
- Reduce caffeine.
- Engage in regular physical activity.12
3. Get Regular Check-Ups
If you’ve ever wondered, "Do I have thyroid issues?", routine thyroid screenings can help catch any abnormalities early. If you’re experiencing signs of thyroid issues or have a family history of thyroid disease, talk to your doctor about getting a TSH (thyroid-stimulating hormone) test to assess your thyroid function.13
Your thyroid is a key player in your overall health, regulating everything from metabolism to reproductive function. Because thyroid disorders are common—especially among women—it’s important to be aware of the symptoms and take proactive steps to support thyroid health.
By prioritizing a nutrient-rich diet, managing stress, exercising regularly, and getting routine check-ups, you can help keep your thyroid functioning optimally. If you’re experiencing persistent symptoms, consult a healthcare professional for personalized advice and treatment.
