The thyroid may be small, but it plays a major role in keeping our bodies running smoothly. Located at the base of the neck, this gland controls many vital functions.

So when it starts misfiring, our bodies often give us clues—some louder than others. Paying attention to even the smallest changes can help us catch thyroid disorders early and get the right treatment.

This article outlines the symptoms of thyroid disease and how age, gender, and diet can influence its development.

Hyperthyroidism

This condition occurs when the thyroid produces too many hormones, causing the body to operate in overdrive.

Common signs include:

1. Irregular or lighter periods – Thyroid issues can disrupt menstrual cycles and affect fertility.
2. Heart palpitations – An increased heart rate is often tied to excess thyroid hormones.
3. Mood changes – Hyperthyroidism may bring anxiety or irritability, often accompanied by other symptoms like weight loss and palpitations.
4. Increased appetite – Metabolism speeds up, making people feel hungrier than usual.
5. Eye problems – These may include dry, red, or bulging eyes, light sensitivity, and blurred vision.
6. Excessive sweating – Moist skin and constant warmth can point to an overactive thyroid.

Age and Gender

In older adults, symptoms like fatigue, weight loss, or an irregular heartbeat may be more subtle. Women over 60 are at higher risk. In teens, hyperthyroidism can lead to rapid growth or early puberty due to hormone overproduction.

Diet Tips

People with an overactive thyroid may benefit from low-iodine foods such as fresh fruits and veggies, egg whites, and foods rich in selenium and iron. It’s best to avoid iodine-rich foods like fish, kelp, dairy, soy, and caffeine.

Hypothyroidism

When the thyroid fails to produce enough hormones, it slows the body down. Symptoms may not be immediately obvious but can still affect various areas.
