Hypothyroidism can develop for several reasons, including:

• Hashimoto’s thyroiditis – the most common cause, an autoimmune condition where the immune system attacks the thyroid gland.

• Thyroid surgery – partial or complete removal of the thyroid can reduce hormone production.

• Radiation therapy – treatment for thyroid cancer or other neck conditions can damage the thyroid.

• Iodine deficiency or excess – although rare in the U.S., imbalanced iodine levels can disrupt thyroid function.

• Certain medications – such as lithium or amiodarone.

Hypothyroidism is more common in women, especially those over age 60, but it can affect people of all ages.

Symptoms of hypothyroidism often develop slowly and can vary widely between individuals. Common signs include:

• Fatigue or low energy

• Unexplained weight gain

• Cold intolerance

• Dry skin and brittle hair

• Depression or mood changes

• Slowed heart rate

• Constipation

• Puffy face

• Hoarseness

• Memory problems or difficulty concentrating (“brain fog”)

• Menstrual irregularities or fertility issues

• Enlarged thyroid gland (goiter)

Because these symptoms can overlap with other conditions, proper diagnosis and testing are essential.

Hypothyroidism is typically a lifelong condition, but with the right treatment, it can be well-managed. North Texas Diabetes & Endocrinology offers individualized care, including:

• Thyroid Hormone Replacement Therapy: The most common and effective treatment involves taking a daily dose of synthetic thyroid hormone (levothyroxine) to restore normal hormone levels.

• Regular Monitoring and Dose Adjustments: We closely monitor your TSH (thyroid-stimulating hormone) levels to ensure your medication dosage is appropriate and make adjustments as needed for optimal health.

• Ongoing Support: Managing hypothyroidism is not just about medication. We also address related concerns such as fatigue, weight management, and mood changes with a holistic approach.
