Thyroid hormone is important for all metabolic activity since it speeds up cellular energy and heat production. Low levels of thyroid hormone can cause a variety of common symptoms, such as feeling cold, fatigue, weight gain, hair loss, depression, brain fog, and sleepiness. From a Chinese Medicine perspective the thyroid gland itself is closely related to Lung function, but any organ system can be implicated in a Western diagnosis of hypothyroid. Simply treating low thyroid by supplementing with thyroid hormone often misses the deeper issue. Without examining the unique individual this can cause more problems in the long-term. Treatment for thyroid issues can include diet, acupuncture, herbs, homeopathy, lifestyle and stress management, all geared towards helping the body self-regulate and return to health.
