The hypothalamus is a small but important area in the center of the brain. It plays an important role in hormone production and helps to stimulate many important processes in the body and is located in the brain, between the pituitary gland and thalamus.
When the hypothalamus is not working properly, it can cause problems in the body that lead to a wide range of rare disorders. Maintaining hypothalamic health is vital because of this.
Hypothalamic dysfunction is a problem with part of the brain called the hypothalamus. The hypothalamus helps control the pituitary gland and regulates many body functions.
The thyroid gland produces two related hormones, thyroxine (T4) and triiodothyronine (T3), which play a critical role in thermogenic and metabolic homeostasis. T4 and T3 are normally synthesized and released in response to a combined hypothalamic pituitary signal mediated by thyroid stimulating hormone (TSH) from the anterior pituitary and thyrotropin releasing hormone (TRH) from the hypothalamus. There is a negative feedback from thyroid hormone concentration, primarily T3, to TSH production, causing total T4, total T3, free T4, and free T3 concentrations to move in opposition to TSH concentration.
Hypothyroidism is a condition in which the thyroid gland is functionally inadequate. Causes of hypothyroidism include autoimmune disorders, such as Hashimoto?s thyroiditis, atrophic thyroiditis, and postpartum thyroiditis; iodine deficiency, the most common cause of hypothyroidism in underdeveloped areas; congenital defects; medications or treatments that can result in hypothyroidism; central hypothyroidism in which the thyroid is not stimulated by the pituitary or hypothalamus; and infiltrative processes that may damage thyroid, pituitary, or hypothalamus. These different causes of hypothyroidism are often interrelated. Usually, the exact cause of the hypothyroidism cannot be definitively differentiated.
Heart rhythm problems (heart arrhythmias) occur when the electrical impulses that coordinate your heartbeats don't work properly, causing your heart to beat too fast, too slow or irregularly.
Heart arrhythmias (uh-RITH-me-uhs) may feel like a fluttering or racing heart and may be harmless. However, some heart arrhythmias may cause bothersome ? sometimes even life-threatening ? signs and symptoms.
Heart arrhythmia treatment can often control or eliminate fast, slow or irregular heartbeats. In addition, because troublesome heart arrhythmias are often made worse ? or are even caused ? by a weak or damaged heart, you may be able to reduce your arrhythmia risk by adopting a heart-healthy lifestyle.
Doctors classify arrhythmias not only by where they originate (atria or ventricles) but also by the speed of heart rate they cause:
Fibromyalgia (fi·bro·my·al·gi·a) is a condition that causes torment everywhere throughout the body (likewise alluded to as across the board torment), rest issues, weariness, and frequently enthusiastic and mental trouble. Individuals with fibromyalgia might be more touchy to torment than individuals without fibromyalgia. This is called strange torment recognition handling. Fibromyalgia influences around 4 million US grownups, about 2% of the grownup populace. The reason for fibromyalgia isn't known, however it very well may be viably rewarded and overseen.
Specific phobias are an overwhelming and unreasonable fear of objects or situations that pose little real danger but provoke anxiety and avoidance. Unlike the brief anxiety you may feel when giving a speech or taking a test, specific phobias are long lasting, cause intense physical and psychological reactions, and can affect your ability to function normally at work, at school or in social settings.
Specific phobias are among the most common anxiety disorders, and not all phobias need treatment. But if a specific phobia affects your daily life, several therapies are available that can help you work through and overcome your fears ? often permanently.
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.
Several treatments are available for hyperthyroidism. Doctors use anti-thyroid medications and radioactive iodine to slow the production of thyroid hormones. Sometimes, hyperthyroidism treatment involves surgery to remove all or part of your thyroid gland.
Although hyperthyroidism can be serious if you ignore it, most people respond well once hyperthyroidism is diagnosed and treated.
