Overactive thyroid (hyperthyroidism).
About hyperthyroidism
Your thyroid is an endocrine gland. This means that it secretes hormones into your bloodstream. Hormones are chemicals produced by your body to help regulate how your cells and organs work. They are sometimes called chemical messengers.

Your thyroid gland makes two hormones: thyroxine (also called T4) and triiodothyronine (also called T3). Together, these hormones regulate your body's growth and metabolism. Your metabolism is how quickly your body burns energy and how quickly reactions in your body happen. Your rate of metabolism affects lots of things, such as how much you weigh and how much you sleep.
The production of your thyroid hormones is controlled by another hormone called thyroid stimulating hormone (TSH). This is made by an endocrine gland in your brain called the pituitary gland.
What is hyperthyroidism?
Hyperthyroidism is when your thyroid gland is overactive and produces excess thyroid hormones. This speeds up your body's metabolism, meaning that organs and processes in your body work faster.
Symptoms of hyperthyroidism
Hyperthyroidism has many different symptoms. In general, the symptoms relate to a speeding up of your body's metabolism. Symptoms include:
feeling nervous, irritable or emotional
tremor (shaking)
sleeping poorly
being intolerant of heat and sweating more than usual
losing weight despite having an increased appetite (although around one in 10 people will gain weight)
feeling tired
muscle weakness
increased heart rate or palpitations
having infrequent periods or problems getting pregnant
having more frequent bowel movements or diarrhoea
shortness of breath, especially when exercising
loss of hair or finer hair than usual
swelling of your thyroid gland (goitre)
swollen/red eyes, or double vision
If you have some, or all, of these symptoms, see your family doctor.
Hyperthyroidism. It is characterized by brittle hair and nails, sensitivity to cold, intolerance to heat, fast heart rate, tremors, heart palpitations, etc. For a complete list of symptoms, see the attached link.
The thyroid is produces a hormone called thyroxine. A hormone that is important in regulating metabolic rate. An under active (too little thyroxine) will slow metabolism leading to weight gain, lack of energy and weight gain. An over active thyroid (too much thyroxine) will lead to weight loss, anxiety & agitation.
Yes, an under-active thyroid gland can eventually become over-active, and vice versa.
A thyroid is a gland. To have one is that is over active simply means that it is producing far more than the average thyroid gland. See a doctor if you have doubts.
help diagnose an underactive thyroid (hypothyroidism), and an overactive thyroid (hyperthyroidism), evaluate thyroid gland activity, monitor response to thyroid therapy
There are different kinds of thyroid disorders. The two most common problems are hyperthyroidism in which the thyroid gland is overactive and hypothyroidism in which the thyroid gland is underactive. Each condition has its distinguished symptoms. However, the two disorders share some similar symptoms such as fatigue, heart problems and menstrual changes.
Hashimoto's causes inflammation of the thyroid gland. It also causes the thyroid gland to become underactive, or hypothyroid
The condition that is associated with the thyroid gland being overactive, which then leads to an increased metabolism, is known as hyperthyroidism. Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormones.
Yes,it means you have a thyroid problem.
The thyroid gland is the most common endocrine gland to produce a disease condition or problem. Conditions such as hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) are frequently seen. Hypothyroidism can result in symptoms like fatigue, weight gain, and depression, while hyperthyroidism can cause symptoms such as weight loss, anxiety, and increased heart rate.
No, actually euthyroid means a normally functioning thyroid gland; it is a state of normal thyroid gland function. The term hyperthyroid means that the thyroid is overactive, and hypothyroid refers to an under active thyroid.
Thyroxine has to do with metabolism. Having an underactive thyroid is a condition called hypothyroidism
overactive thyroid gland
The most common type of thyroiditis is Hashimoto's disease
A diet high in certain types of fats is one factor. Medical problems such as poorly controlled diabetes, an underactive thyroid gland, an overactive pituitary gland, liver disease or kidney failure also may cause high cholesterol levels.
The thyroid gland is essential for human health. It can be overactive or under active in certain people, though this is easily treated medically. It can become cancerous, but it is a very treatable form of cancer (very low mortality rate). The thyroid gland helps to control the speed of human metabolism.
