The Differences Between Hypothyroidism and Hyperthyroidism Hypothyroidism causes symptoms like slowed metabolism, tiredness, and weight gain. Having an underactive thyroid can decrease or slow down your bodily functions. With hyperthyroidism, you may find yourself with more energy, as opposed to less.

The difference between an underactive and an overactive thyroid is: An underactive thyroid can be easily treated with hormone replacement (thyroxine) with no side effects. An overactive thyroid is a potentially fatal health condition if left undiagnosed and untreated.

Hypothyroidism is a problem with your thyroid gland; Hashimoto's is a problem with your immune system.

Higher levels suggest hypothyroidism, or an underactive thyroid, while lower levels indicate hyperthyroidism, or an overactive thyroid. When TSH and thyroid hormones are out of balance, this can cause a range of issues relating to the muscles, breathing, body temperature, and more.

Taking too much thyroid hormone can cause heart rhythm problems, and may even damage your bones over time. With a diagnosis of hyperthyroidism, your doctor may prescribe anti-thyroid or beta-blocker medicines to reduce your symptoms.

Hypothyroidism may be due to a number of factors, including: Autoimmune disease. The most common cause of hypothyroidism is an autoimmune disorder known as Hashimoto's thyroiditis. Autoimmune disorders occur when your immune system produces antibodies that attack your own tissues.

In People Without Known Thyroid Disease While often associated with hyperthyroidism, a low TSH could also be a sign of central hypothyroidism. Central hypothyroidism: Less commonly, a lack of TSH produced by the pituitary gland (due to its dysfunction) can lead to low thyroid levels in the blood.

Hyperthyroidism causes mild decreases in total white blood cell count, neutropenia, thrombocytopenia and increases, normal or mild decreases in total white blood cell count. Generally it seems that hypothyroidism causes hypoplasia in all myeloid cell lineages and hyperthyroidism result in hyperplasia.

Overview. Hyperthyroidism (overactive thyroid) occurs when your thyroid gland produces too much of the hormone thyroxine. Hyperthyroidism can accelerate your body's metabolism, causing unintentional weight loss and a rapid or irregular heartbeat.

Because it doesn't cause any symptoms, subclinical hypothyroidism isn't noticeable. The TSH (thyroid-stimulating hormone) value is too high, but the thyroid is still producing enough hormones. This hormone is produced in the pituitary gland and acts as a trigger for the thyroid to start producing the thyroid hormones.

It can be primary or secondary: Primary hyperthyroidism is the term used when the pathology is within the thyroid gland. Secondary hyperthyroidism is the term used when the thyroid gland is stimulated by excessive thyroid-stimulating hormone (TSH) in the circulation.

The causes of subclinical hypothyroidism are the same as those of (overt) hypothyroidism and include chronic lymphocytic (Hashimoto's) thyroiditis, partial thyroidectomy, radioactive iodine therapy, and damage to the thyroid from radiation treatment.

High TSH levels can mean your thyroid is not making enough thyroid hormones, a condition called hypothyroidism. Low TSH levels can mean your thyroid is making too much of the hormones, a condition called hyperthyroidism. A TSH test does not explain why TSH levels are too high or too low.

Both hypothyroidism and hyperthyroidism cause respiratory muscle weakness and decrease pulmonary function. Hypothyroidism reduces respiratory drive and can cause obstructive sleep apnea or pleural effusion, while hyperthyroidism increases respiratory drive and can cause dyspnea on exertion.

Some of the major symptoms of hyperthyroidism are hot flashes, irritability and heart palpitations. Often patients lose weight without trying or gain weight due to excess hunger. When too little of the thyroid hormone is produced, it causes hypothyroidism, or underactive thyroid.

Low TSH levels indicate hyperthyroidism. This is also known as an overactive thyroid. If the thyroid gland is secreting levels of hormones that are too high, the pituitary gland produces less TSH. Symptoms of hyperthyroidism include: an irregular or rapid heartbeat.

The Bottom Line Hypothyroidism, or low thyroid, is a common disorder. It can cause a variety of symptoms, such as fatigue, weight gain and feeling cold. It can also result in problems with your hair, skin, muscles, memory or mood. Importantly, none of these problems are unique to hypothyroidism.
