Thyroid Disorders

The thyroid is a small, butterfly-shaped gland in the front of your neck that produces hormones that help regulate metabolism, energy, heart rate, temperature, and weight. When thyroid hormone levels are too high or too low, it can affect many body systems and cause symptoms like fatigue, weight changes, mood changes, and irregular heartbeat.

A thyroid disorder happens when the thyroid produces too much hormone (hyperthyroidism), too little hormone (hypothyroidism), or develops structural changes like thyroid nodules, goiter, inflammation (thyroiditis), or, less commonly, thyroid cancer. A thyroid specialist can confirm the cause with labs and imaging and guide treatment.

Hypothyroidism (underactive thyroid) can cause: Fatigue or low energy; Weight gain or difficulty losing weight; Feeling cold easily; Dry skin or hair thinning; Constipation; Slower heart rate or 'sluggish' feeling. Symptoms can be subtle at first, so testing is the best way to confirm what's going on.

Hyperthyroidism (overactive thyroid) may cause: Fast heartbeat or palpitations; Anxiety, irritability, or shakiness; Unexplained weight loss; Heat intolerance and sweating; Trouble sleeping; Frequent bowel movements. One common cause is Graves' disease, which is treatable with medical care.

Common causes include autoimmune conditions such as Hashimoto's thyroiditis (a leading cause of hypothyroidism) and Graves' disease (a leading cause of hyperthyroidism). Thyroid issues can also be linked to thyroiditis, iodine imbalance, certain medications, nodules, or family history. Identifying the cause matters because it helps determine the safest treatment plan.

Thyroid testing usually starts with bloodwork, including TSH and Free T4 (and sometimes T3 and thyroid antibodies). If there's a lump, swelling, or concern for nodules, your provider may recommend a thyroid ultrasound and, if needed, a biopsy (FNA). Testing helps clarify whether symptoms are thyroid-related and guides treatment.

Treatment depends on the diagnosis: Hypothyroidism is typically treated with thyroid hormone replacement (commonly levothyroxine); Hyperthyroidism may require medication, monitoring, and sometimes additional therapies; Nodules/goiter are managed with ultrasound monitoring and biopsy when indicated; Thyroiditis treatment is based on cause and symptom control. Your plan should be personalized based on labs, symptoms, and overall health.

Consider seeing a thyroid specialist if you have persistent symptoms (fatigue, weight changes, palpitations), abnormal thyroid labs, a thyroid nodule/goiter, or a history of autoimmune disease.
