WHAT IS THE RELATIONSHIP BETWEEN THYROID AND WEIGHT?
There is a complex relationship between the thyroid, body weight and metabolism. The thyroid regulates metabolism and directly influence an individuals weight. It releases hormones that control metabolism—the way your body uses energy.
The thyroid is part of the endocrine system, which is made up of glands that produce, store, and release hormones into the bloodstream. The thyroid gland uses iodine from the foods you eat to make two main hormones Triiodothyronine (T3) and Thyroxine (T4).
It is important that T3 and T4 levels are neither too high nor too low.
In hypothyroidism levels of thyroid hormone are to low and will cause a slow metabolism. Typical symptoms of low thyroid include
Difficulty losing weight / Slow Metabolism
Sensitivity to cold temperature
Metabolism is determined by measuring the amount of oxygen used by the body over a specific amount of time. If the measurement is made at rest, it is known as the basal metabolic rate (BMR). Patients whose thyroid glands were not working were found to have low BMRs, and those with overactive thyroid glands had high BMRs. Later studies linked these observations with measurements of thyroid hormone levels and showed that low thyroid hormone levels were associated with low BMRs and high thyroid hormone levels were associated with BMRs.
If you have difficulty losing weight consider asking your doctor to check a full complete thyroid panel.
