Depending on the type of thyroid issue, different symptoms and causes can be associated with different thyroid illnesses. Hypothyroidism (an underactive thyroid) and hyperthyroidism (an overactive thyroid) are the two most prevalent thyroid disorders. Here are some typical signs and their corresponding causes:
Hypothyroidism (Underactive Thyroid):
Hypothyroidism happens when the thyroid gland doesn’t make enough thyroid hormone. This condition also is called underactive thyroid. Hypothyroidism may not cause noticeable symptoms in its early stages. Over time, hypothyroidism that isn’t treated can lead to other health problems, such as high cholesterol and heart problems.
- Fatigue and weakness
- Weight gain or difficulty losing weight
- Cold intolerance
- Dry skin and hair
- Depression or mood changes
- Muscle aches and stiffness
- Impaired memory and concentration
- Menstrual irregularities
The most common cause of hypothyroidism is an autoimmune condition called Hashimoto’s thyroiditis, in which the immune system mistakenly attacks the thyroid gland. Other causes can include thyroid surgery, radiation therapy, certain medications, and congenital factors.
Hyperthyroidism (Overactive Thyroid):
- Unintentional weight loss
- Rapid or irregular heartbeat
- Increased sweating
- Heat intolerance
- Tremors or shaking hands
- Nervousness or anxiety
- Difficulty sleeping
- Frequent bowel movements
- Fatigue or muscle weakness
The most common cause of hyperthyroidism is an autoimmune disorder called Graves’ disease, where the immune system produces antibodies that stimulate the thyroid gland to produce excessive hormones. Other causes can include thyroid nodules, thyroid inflammation, and certain medications.
It’s important to note that these symptoms are not exclusive to thyroid disorders, and they can also be caused by various other health conditions.
