Understanding the Symptoms of Hyper-Hypo-Thyroidism
What Is A Thyroid?
"The thyroid is a butterfly-shaped gland located in the neck in the front of the windpipe. In healthy people, the thyroid makes just the right amounts of two hormones, T4 and T3, which perform important actions throughout the body. These hormones regulate many aspects of our metabolism, affecting everything from our temperature, mood, muscle strength and appetite to heart rate." (Source: John Hopkins University)
When Should A Thyroid Be Tested?
"Like routine screenings for high blood pressure and breast cancer, screening for an underactive thyroid gland should be part of periodic examinations for people over age 35, especially women, a Johns Hopkins-led study suggests.
The findings contradict current recommendations by most physician groups that such thyroid screenings are unnecessary in the general population
"Routine thyroid screenings may prevent a mild problem from becoming severe" (source -John Hopkins University)".
Symtoms Of Hypothyrodism
"Symptoms may become evident over the course of a few weeks, or they may gradually emerge over several months or years.
Some people may begin to notice that they are unable to tolerate cooler temperatures that feel perfectly comfortable to others around them. This symptom is called cold intolerance.
Some peopele may experience a substantial amount of weight gain due to changes in rates of energy consumption and metabolism.
Some peope may feel tired and lethargic much of the time, sleeping for long periods without feeling energized or refreshed.
Changes in behavior may be noticed." (Source-John Hopkins University)
"Hyper" Thyroidism? Is Much More Complicated
"Most of these symptoms are related to exposure to excess amounts of thyroid hormone.
Physical signs that may become apparent in patients who develop thyrotoxicosis reflect exposure to excess amounts of thyroid hormone.
People who develop thyrotoxicosis may be noted to have an accelerated heart rate as a result of increased stimulation of the cardiovascular system.
If measurement of the pulse reveals that a person's heart is beating at a rate faster than 100 beats per minute, this acceleration is called tachycardia.
Increased stimulation of the cardiovascular system may also lead to the development of abnormal heart rhythms called arrhythmias.
In most situations when an irregular pulse is detected, an electrocardiogram must be performed to determine if an underlying arrhythmia is present.
thyrotoxicosis may reveal warm moist skin that is very smooth in texture.
Characteristic skin changes may be related to increased blood flow in the tissues supporting the skin and increased stimulation of the sweat glands.
Testing of the reflexes may reveal sharp forceful contraction of muscles when tendons in the arms, knees, and ankles are tapped with a reflex hammer.
Further testing may reveal evidence of a fine tremor when a patient is asked to hold a hand out to keep it steady.
Muscle strength may be noted to be decreased when a patient is asked to push or pull against fixed resistance.
Increased contraction of the muscles that open the upper eyelids may be associated with a finding called retraction.
A toxic multinodular goiter is a disorder that may develop when there is enlargement of the thyroid gland caused by the growth of multiple thyroid nodules that produce and secrete excess amounts of thyroid hormone.
"Iodine-induced hyperthyroidism is a condition that may develop when a susceptible patient is exposed to an excessive amount of iodine." (source- John Hopkins University)
