Thyroid Dysfunction & Hypothyroidism Treatment

Tired, Cold and Gaining Weight Even With 'Normal' Thyroid Labs?

The thyroid gland is small, but it controls some of the body’s most important functions—including metabolism, energy, temperature regulation, and mood. When it isn’t working properly, symptoms can ripple through your entire system. At Optimize Integrative Health, we take a root-cause, personalized approach to diagnosing and treating thyroid dysfunction so you can regain balance and long-term vitality.

What Is Thyroid Dysfunction?

Thyroid dysfunction occurs when the thyroid gland, located at the base of the neck, produces either too little hormone (hypothyroidism) or too much hormone (hyperthyroidism).

  • Hypothyroidism slows metabolism, leaving you feeling fatigued, sluggish, and prone to weight gain.
  • Hyperthyroidism speeds metabolism up, often causing weight loss, anxiety, and rapid heart rate.

Both conditions can disrupt energy, mood, sleep, and overall health if left untreated.

What Shapes Your Thyroid Health?

Several factors can contribute to thyroid imbalances, including:

Autoimmune Disorders

Hashimoto’s (underactive thyroid) or Graves’ Disease (overactive thyroid)

Iodine Levels

Both deficiency and excess can trigger dysfunction

Genetics

Family history increases risk

Medications

Lithium, amiodarone, and others may affect thyroid function

Radiation Exposure

Past cancer treatments in the head/neck region

Pregnancy

Postpartum thyroiditis can temporarily or permanently affect function
