Thyroid Disorder Q & A


What is a thyroid disorder? 

Your thyroid is a butterfly-shaped gland in your neck that produces hormones controlling functions like your metabolism — how your body uses energy. When your thyroid makes too much hormone (hyperthyroidism), this process speeds up. When it doesn’t make enough (hypothyroidism), everything slows down.

Without proper treatment, thyroid disorders can affect your quality of life and lead to serious complications like heart problems, osteoporosis, or depression.

What causes thyroid problems? 

Several factors can trigger thyroid disorders:

  • Autoimmune conditions like Hashimoto’s disease or Graves’ disease
  • Thyroid nodules or goiter
  • Pregnancy or hormonal changes
  • Certain medications
  • Iodine deficiency or excess
  • Family history of thyroid disease
  • Stress or illness

Sometimes thyroid problems develop gradually, making them easy to miss until symptoms become more obvious.

What are the symptoms of a thyroid disorder? 

The symptoms depend on whether your thyroid is overactive or underactive.

Hypothyroidism symptoms include:

  • Fatigue and weakness
  • Weight gain
  • Feeling cold
  • Dry skin and hair
  • Depression
  • Memory problems
  • Constipation

Hyperthyroidism symptoms include:

  • Rapid heartbeat
  • Weight loss
  • Feeling hot
  • Sweating
  • Anxiety
  • Irritability
  • Trouble sleeping
  • Frequent bowel movements

Many people dismiss these symptoms as typical signs of aging or stress, but they don’t have to be your new normal.

How are thyroid disorders diagnosed? 

At United Family Physicians, your doctor starts with a thorough discussion of your symptoms and medical history. They perform a physical exam, checking your neck for thyroid enlargement or nodules.

Blood tests measure your thyroid hormone levels (TSH, T3, and T4) and can detect autoimmune markers. If necessary, your doctor may recommend imaging studies, such as an ultrasound, for a close review of your thyroid structure.

How are thyroid disorders treated? 

Treatment depends on your specific condition. For hypothyroidism, hormone replacement medication helps restore normal levels. Hyperthyroidism treatment might include medications to slow hormone production, radioactive iodine therapy, or, in some cases, surgery.

Your United Family Physicians doctor monitors your progress, adjusting treatment as needed to help you feel your best. With proper management, most people with thyroid disorders live completely normal, healthy lives.
