What does high TSH thyroid stimulating hormone levels indicate?
What does the test result mean?
NOTE: A standard reference range is not available for this test. Because reference values are dependent on many factors, including patient age, gender, sample population, and test method, numeric test results have different meanings in different labs. Your lab report should include the specific reference range for your test. Lab Tests Online strongly recommends that you discuss your test results with your doctor. For more information on reference ranges, please read Reference Ranges and What They Mean.
A high TSH result often means an underactive thyroid gland that is not responding adequately to the stimulation of TSH due to some type of acute or chronic thyroid dysfunction. Rarely, a high TSH result can indicate a problem with the pituitary gland, such as a tumor producing unregulated levels of TSH. A high TSH value can also occur when patients with a known thyroid disorder (or those who have had their thyroid gland removed) are receiving too little thyroid hormone medication. A low TSH result can indicate an overactive thyroid gland (hyperthyroidism) or excessive amounts of thyroid hormone medication in those who are being treated for an underactive (or removed) thyroid gland. Rarely, a low TSH result may indicate damage to the pituitary gland that prevents it from producing adequate amounts of TSH. Whether high or low, an abnormal TSH indicates an excess or deficiency in the amount of thyroid hormone available to the body, but it does not indicate the reason why. An abnormal TSH test result is usually followed by additional testing to investigate the cause of the increase or decrease. The following table summarizes test results and their potential meaning. TSH T4 T3 Interpretation High Normal Normal Mild (subclinical) hypothyroidism High Low Low or normal Hypothyroidism Low Normal Normal Mild (subclinical) hyperthyroidism Low High or normal High or normal Hyperthyroidism Low Low or normal Low or normal Nonthyroidal illness; Rare pituitary (secondary) hypothyroidism
Is there anything else you should know?
Many medications - including aspirin and thyroid-hormone replacement therapy - may affect thyroid gland function test results, so tell your doctor about any drugs you are taking. When your doctor adjusts your dose of thyroid hormone, it is important to wait at least one to two months before checking your TSH again so that your new dose can have its full effect. Extreme stress and acute illness may also affect TSH test results, and results may be low during the first trimester of pregnancy. What does the test result mean?

How do you take care of your endocrine system?
The Endocrine System by:Dr.A. Leonardo The Endocrine System The endocrine system is an information signaling system much like the nervous system. However, the nervous system uses nerves to conduct information, whereas the endocrine system uses blood vessels as information channels. Glands located in many regions of the body release into the bloodstream specific chemical messengers called hormones, which regulate the many and varied functions of an organism. The typical endocrine organ is a ductless gland that secretes chemical mediators directly into local blood vessels which circulate within the body via the bloodstream. These hormones travel to distant organs to regulate the target organ's function. This is classical endocrine signalling. Other signalling can target the same cell (known as Autocrine signalling) or nearby cells (known as Paracrine signalling). Hormones are also instrumental in regulating mood, growth and development, tissue function, and metabolism, as well as sending messages and acting on them. A number of glands which signal each other in sequence is usually referred to as an axis, for example the Hypothalamic-pituitary-adrenal axis. Typical endocrine glands are the pituitary, thyroid, and adrenal glands. Features of endocrine glands are typically their ductless nature, their vascularity and usually the presence of intracellular vacuoles or granules storing their hormones. In contrast exocrine glands such as salivary glands, sweat glands and glands within the gastrointestinal tract tend to be much less vascular and have ducts or a hollow lumen.
Can you get a headache after an adrenaline rush?
this is not valid this is only guessing but your body produces adrenaline at the right amount at the necessary time but there are ways of artafitially putting it into your system like adrenaline needles which can probably harm or kill you if abused but again i am not one hundred percent sure

What to expect after thyroid surgery?
I had my thyroid removed in December. I was sure to read all the bad news about thyroid removal to prepare myself for the worse! However, i have had some good results. I was out of work a week and a half, gained only 2 pounds in 7 months, and have a small scar about an inch long that continues to improve. I also was fortunate enough to have found the right level of synthroid after 2 doctor visits. So I am very happy with the results! My doctor advised me to not exceed 5 lbs in weight gain or loss in order to maintain the level of synthroid I take now. All is well!
What causes diabetes mellitus?
Type 1 Diabetes is a chronic, autoimmune disorder in which white blood cells attack the insulin-secreting beta cells inside the pancreas. One of the results being the loss of the body to produce enough insulin. Despite being considerable advances in treating diabetes it is always important to keep blood sugar levels under control unless they can bring a host of other complications such as renal (kidney) failure, heart problems, blindness, and some other things.
Do you fast for thyroid blood test?
When having a Total iron-binding capacity (TIBC) or transferrin, than it is necessary to avoid eating or drinking for 8 hours before the blood test. It is not necessary to fast when having a ferritin blood test.
Glands such as thyroid that secrete their product directly in the blood are a part of the endocrine system. The endocrine system includes the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.
What are the components of endocrine system?
This system is made of glands that help reduce and secrete hormones that regulate the bodys growth, metabolism and sexual development and function. Major gland components are the hypothalamus, pituitary gland, thyroid gland, pancreas, pineal and reproductive organs, adrenals, and parathyroids.
How is a diagnosis of diabetes mellitus confirmed?
There are several diagnostic exams to know if you have diabetes mellitus. The most common is the Fasting Blood Sugar test and the Random Blood sugar test. This will determine you Blood Sugar count. There is also the OGTT or the oral Glucose test. If you have already been started with a regimen for diabetes, the doctor usually orders you a HBA1c or glycoselated hemoglobin.
What gland is next to thyroid gland?
The gland that is located in the neck, next to the thyroid gland is the parathyroid. Most people have four parathyroid glands. The parathyroid glands are very small in size, almost the size of a grain of rice, which are located around the surface of the thyroid gland. The parathyroid produces a hormone called the parathyroid hormone. According toparathyroid.com, the major function of the parathyroid glands are to maintain the body's normal balance of calcium levels in the blood as well as the bones. Maintaining a normal range of parathyroid hormones also affects the nervous and muscular systems.
Which hormones secreted by the body controls the contractions of the uterus wall during birth?
Oxytocin stimulates the uterus to contract and prostaglandins soften your cervix. Oxytocin's nickname is the love hormone, it is present during lovemaking, labor, birth, and directly following the birth in the early postpartum hours and also when you nurse your baby.
What describes a feedback mechanism of the endocrine system?
When the level of a certain hormone gets too high, it stimulates the hypothalamus and anterior pituitary gland to release an inhibatory hormone to make the gland that is secreting the hormone stop making more of it so the level goes down.
What does the FSH stimulate in women?
High levels of the hormone oestrogen stimulates the production of FSH hormone in women.
