Age factor and our Thyroid

Thursday Nov 10, 2011 | Dr. Said | Comments Off on Age factor and our Thyroid

Thyroid gland  is one of the largest endocrine glands. The thyroid gland is found in the neck, below Adam’s Apple’).  The thyroid gland controls how quickly the body uses energy, makes proteins, and controls how sensitive the body should be to other hormones. It participates in these processes by producing thyroid hormones, the principal ones being triiodothyronine  (T3) and thyroxine (T4). These hormones regulate the rate of metabolism and affect the growth and rate of function of many other systems in the body. produces calcitonin, which plays a role in calcium homeostasis.

Thyroid disease is more common than diabetes or heart disease. Thyroid disease is a fact of life for as many as 27 million Americans – and more than half of those people remain undiagnosed. Women are five times more likely than men to suffer from hypothyroidism (when the gland is not producing enough thyroid hormone),also aging is just one other risk factor for hypothyroidism. Because there are varying degree of hypothyroidism and other thyroid problems, the proper dosage of synthroid will vary from person to person. The recommended dose will be based on factors such as your age, other medical conditions you have, and the result of certain blood tests. As people age their requirement for thyroid hormone replacement might decrease because there is a natural reduction of thyroid hormone production, Growth hormone (GH), secretion, and other hormones, and  degradation with the years. People taking levothyroxine and synthroid, therefore, may require periodic dose reductions under there doctor supervision.




This is important because overtreatment with levothyroxine can have adverse effects such as increased heart rate and an increase in the risk for atrial fibrillation.
Also, hyperthyroidism itself is known to be associated with decreased bone quality and bone mineral density.

To prevent overtreatment and its potention risk have a TSH test at least once per year and be watchful for the signs and symptoms of hyperthyroidism (increased heart rate, heat intolerance, weight loss, irritability, fatigue and difficulty sleeping).

Unless otherwise ordered by your physician it is usually best to take your thyroid replacement in the morning at least 30 minutes before breakfast for the best absorption. It is equally important to be consistent whenever you take it.
