1. Fatigue:
Fatigue is a common symptom of an underactive thyroid (hypothyroidism). It occurs because the body's metabolism slows down, leading to reduced energy levels.
2. Weight changes:
Thyroid dysfunction can cause unexplained weight gain or weight loss due to its impact on the body's metabolism.
3. Hair loss:
Thinning hair and hair loss can be associated with both hyperthyroidism and hypothyroidism, as thyroid hormones affect hair follicles.
4. Irregular menstrual cycles:
Thyroid disorders may lead to irregular or heavy menstrual periods, which can affect fertility in women.
5. Cold intolerance:
Feeling unusually cold, even in warm temperatures, is a common symptom of hypothyroidism, as it reduces the body's ability to regulate temperature.
6. Muscle weakness:
Weakness in the muscles, often accompanied by aches and pains, can result from thyroid imbalances.
7. Mood swings:
Thyroid dysfunction can lead to mood swings, depression, anxiety, and irritability, as it influences brain chemistry.
8. Dry skin:
Dry, itchy skin can be a symptom of hypothyroidism, as the thyroid's hormonal imbalance affects skin moisture.
9. Constipation:
Sluggish digestion and constipation are frequently reported by individuals with hypothyroidism due to reduced bowel motility.
10. Difficulty concentrating:
Thyroid issues can impair cognitive function, making it challenging to focus and concentrate.
