Overactive Thyroid Symptoms

Overactive Thyroid: Symptoms, Causes, and Treatment

What is an Overactive Thyroid?

An overactive thyroid, also known as hyperthyroidism, occurs when the thyroid gland produces excessive amounts of thyroid hormones. These hormones regulate various bodily functions, including metabolism, growth, and development. An overactive thyroid can lead to a range of symptoms, including:

Symptoms of an Overactive Thyroid

• Increased heart rate and palpitations
• Weight loss despite increased appetite
• Sweating, heat intolerance, and warm, moist skin

Other common symptoms include:

• Anxiety, nervousness, and irritability
• Muscle weakness and fatigue
• Frequent bowel movements and diarrhea

In severe cases, an overactive thyroid can lead to:

• Heart failure
• Thyroid storm (a medical emergency characterized by severe symptoms)
• Eye problems, such as bulging eyes and double vision

Causes of an Overactive Thyroid

The most common cause of an overactive thyroid is Graves' disease, an autoimmune disorder in which the body produces antibodies that stimulate the thyroid gland to produce excessive hormones. Other causes include:

• Thyroid nodules (non-cancerous growths on the thyroid)
• Thyroiditis (inflammation of the thyroid)
• Certain medications, such as lithium and amiodarone

Treatment for an Overactive Thyroid

The treatment for an overactive thyroid depends on the underlying cause and severity of symptoms. Options include:

• Anti-thyroid medications to reduce hormone production
• Radioactive iodine to destroy thyroid cells and reduce hormone production
• Surgery to remove part or all of the thyroid gland

It's important to manage an overactive thyroid as untreated it can lead to serious health complications. If you experience any symptoms of an overactive thyroid, consult a healthcare professional promptly.
