Signs & Symptoms of a Low Thyroid
The thyroid is a small gland located in the neck and is responsible for producing hormones that regulate the rate at which our cells utilize the fuel that we take in from our diet. These thyroid hormones can have a major impact on how we feel on a daily basis. A dysfunction in this gland can lead to a wide array of negative signs and symptoms.
The following are a few signs & symptoms of low thyroid production (hypothyroidism):
* weight gain
* puffy face
* decreased sexual interest
* cold intolerance
* cold hands and feet
* brittle nails
* swollen legs, feet, hands or abdomen
* rough dry skin
* menstrual irregularities
Thyroid hormones can have a major impact on how we feel on a daily basis.
Free T4 and Free T3 – These are 2 separate tests, but we will discuss both together.
Ideal range for Free T4 is in the middle of the reference range and up, (.27-4.5 mIU/L. ) and the ideal range for Free T3 is within the upper 75th percentile of the reference range.
This is Part 3 of our discussion on Blood Testing For Thyroid MetabolismReverse T3 – This thyroid hormone needs to be analyzed along with Free T3. (Free T3 is discussed in more detail in Part 2 1 of Blood Testing For Thyroid Metabolism)Reverse T3 is a blocking hormone that is produced from T4 and actually slows down the metabolism.I tell my patients that T3 is like the body’s gas pedal and reverse T3 is like the brake pedal.We need to have a proper balance between these two hormones in order for our metabolism to function optimally.
There are many factors that can contribute to elevated reverse T3,nutrient deficienciesincreased levels of stress hormoneschemical toxinsheavy metalscertain medicationsinflammation.
Ideal range for reverse T3 is to look at the ratio between free T3 and reverse T3. The reference range that most labs give for reverse T3 is 8-25 ng/dl and 2.3-4.2 pg/ml for free T3.
Thyroid Antibodies (thyroid peroxidase and thyroglobulin antibodies) – This is the last of the thyroid tests that I typically recommend AND concludes our 4-Part Series on Blood Testing For Thyroid Metabolism.
