Comprehensive Thyroid Evaluation should be considered if you are tired and sluggish, feel cold all over or have cold hands and feet, require excessive amounts of sleep to function properly, have increased weight even on a low calorie diet, gain weight easily, have difficult or infrequent bowel movements, are depressed or lack motivation, experience morning headaches that wear off as the day progresses, notice thinning of the outer 1/3rd of your eyebrows, have dry skin or scalp or are mentally slugggish. Any of these symptoms can be an indication that your thyroid gland is not performing optimally (hypothyroid).

Your thyroid may be overactive (hyperthyroid) if you experience heart palpitations, inward trembling, increased pulse at rest, are nervous or emotional and have trouble sleeping.

A comprehensive thyroid assessment will evaluate for hypothyroidism, autoimmune hypothyroidism (Hashimoto's thyroiditis) and hyperthyroidism.
