5 Easy-to-Miss Signs of a Thyroid Problem

The thyroid gland secretes hormones that affect many bodily functions, including heart rate, breathing, and digestion. However, many people suffer from thyroid imbalances without realizing it.
Unfortunately, without treatment, these imbalances can cause long-term health complications ranging from fatigue and weight gain to blood clots, heart failure, and stroke.
Our Jacksonville ENT Surgery specialists work closely with endocrinologists and other providers to diagnose and treat thyroid disorders with medical interventions that range from medication to surgery.
Here are some easy-to-miss signs that could indicate a thyroid problem:
1. Unexplained fatigue
Feeling exhausted, even after a full night's sleep? Thyroid disorders, particularly hypothyroidism, can leave you feeling sluggish and drained.
2. Sudden weight changes
Watching your diet closely and exercising regularly but struggling to lose weight? Or have you noticed unexpected weight loss?
An underactive thyroid (hypothyroidism) can slow metabolism, causing weight gain, while an overactive thyroid (hyperthyroidism) can lead to rapid weight loss.
3. Mood swings and depression
Your thyroid affects brain function and mood. Hypothyroidism is often linked to depression and brain fog, while hyperthyroidism can cause anxiety, restlessness, and irritability.
4. Dry skin and hair thinning
If your skin has become excessively dry or your hair is thinning, it could be a sign of thyroid dysfunction.
Hypothyroidism often leads to brittle hair and nails, while hyperthyroidism can cause hair thinning all over the scalp.
5. Sensitivity to temperature
Do you always feel cold, even when others are comfortable? Or do you find yourself sweating excessively?
Thyroid issues can affect temperature regulation: Hypothyroidism makes you more sensitive to cold, while hyperthyroidism causes excessive heat intolerance.
The rest of the story
Because thyroid disease can cause a multitude of symptoms, we think it’s pertinent to include a few more signs and symptoms that may indicate a problem:
Digestive troubles
Frequent constipation or diarrhea might be more than just a dietary issue. An underactive thyroid slows digestion, leading to constipation, while an overactive thyroid speeds it up, causing frequent bowel movements or diarrhea.
Puffy face and swelling
Unexplained swelling, especially in the face, hands, or feet, can be a sign of hypothyroidism. This is due to fluid retention caused by a sluggish metabolism.
Muscle weakness and joint pain
Experiencing unexplained muscle weakness or joint pain? Hypothyroidism can lead to muscle stiffness and aches, while hyperthyroidism can cause muscle weakness, particularly in the thighs and upper arms.
Hoarseness or a swollen neck
A noticeable swelling in the neck or a persistent hoarse voice can indicate an enlarged thyroid gland (goiter). This could be due to iodine deficiency, inflammation, or thyroid nodules.
Irregular menstrual cycles
For women, changes in menstrual cycles — such as heavier or lighter periods, irregular timing, or even missed periods — can be linked to thyroid dysfunction. Hypothyroidism often causes heavy periods, while hyperthyroidism may lead to lighter or absent ones.
What’s next?
Early detection and treatment can help manage symptoms and prevent complications of thyroid problems. Blood tests and imaging studies, such as ultrasounds, can help identify thyroid issues that require further care.
