It may be small, but the thyroid plays a crucial role in keeping the body balanced. Sitting at the base of the neck, this gland influences many essential processes.

When it begins malfunctioning, the body often sends signals—some obvious, some easy to miss. Noticing minor shifts early can help detect thyroid issues and get proper care sooner.
This article explains the symptoms of thyroid disorders and how factors like age, gender, and diet can play a part in their development.

Hyperthyroidism
This condition happens when the thyroid releases too much hormone, pushing the body into a heightened state.
Typical symptoms include:
Irregular or lighter periods – Thyroid problems can interfere with menstrual patterns and impact fertility.
Heart palpitations – A rapid heartbeat is often linked to excessive thyroid hormones.
Mood shifts – Anxiety or irritability may appear with hyperthyroidism, often along with weight loss or palpitations.
Increased hunger – A faster metabolism can make you feel hungrier than normal.
Eye issues – These can include redness, dryness, bulging, sensitivity to light, or blurry vision.
Heavy sweating – Warm, moist skin may signal an overactive thyroid.
Age and Gender
For older adults, signs like tiredness, weight loss, or an irregular heartbeat may be less noticeable. Women over 60 face a greater risk. In teenagers, hyperthyroidism can trigger fast growth or early puberty because of excess hormones.
Diet Suggestions
Those with an overactive thyroid might do better with low-iodine foods such as fresh produce, egg whites, and items high in selenium and iron. Iodine-rich foods like seafood, kelp, dairy, soy, and caffeine are best avoided.
Hypothyroidism
When the thyroid doesn’t make enough hormones, the body’s functions begin to slow. Symptoms can be subtle at first, yet they can still affect different systems.
As one Reddit user mentioned, “My eyebrows have been thinning… it’s the ONLY symptom I am having right now.”
Possible indicators include:
Thinning eyebrows – Often starting at the outer ends, but treatable once hormone levels are corrected.
Dry, fragile nails – Nails may become brittle, ridged, or lift from the nail bed.
Forgetfulness – Low hormone levels can cause mental fog and memory lapses.
Cold hands and feet – A slower metabolism may lead to cold extremities and cracked skin.

Diet and Age Considerations
Although iodine is necessary, too much—especially from supplements or seaweed—can aggravate autoimmune thyroid issues. Pregnant women require additional iodine but should monitor their intake closely.
Babies with hypothyroidism might not show symptoms right away, but untreated cases can cause developmental problems. Adolescents may experience delayed puberty, limited growth, and slowed cognitive development.
How Stress Plays a Part
Stress can intensify thyroid symptoms or slow healing. Using mindfulness, physical activity, counseling, or yoga can help support overall thyroid function.
Our bodies constantly communicate with us. Paying attention to these signals can lead to earlier diagnosis and better health outcomes.
