Can hyperthyroidism cause mental illness?
After being diagnosed with hyperthyroidism, I have been feeling emotionally unstable. I would like to ask, can hyperthyroidism cause mental illness?

Hyperthyroidism refers to an overactive thyroid gland. Under normal circumstances, hyperthyroidism may cause psychiatric disorders.
Hyperthyroidism is a condition caused by excessive production of thyroid hormones by the thyroid gland, leading to a variety of clinical symptoms. Common symptoms include palpitations, hand tremors, and anxiety. To some extent, these symptoms may affect the patient's psychological state, triggering or worsening emotional problems such as anxiety and depression. If left untreated or poorly controlled over a long period, these symptoms may progress to psychiatric symptoms such as hallucinations and auditory hallucinations, which fall under the category of organic mental disorders.
In addition, during hyperthyroidism, the body's metabolic rate significantly increases, potentially leading to excessive energy consumption that can impair normal brain function, causing symptoms such as difficulty concentrating and memory loss. At the same time, patients often experience insomnia or decreased sleep quality, and prolonged sleep deprivation can further exacerbate emotional problems and even trigger psychiatric disorders.
It is recommended to maintain healthy lifestyle habits in daily life, such as regular作息 (作息 should be replaced with appropriate English term like "sleep patterns" or "daily routines") and avoiding staying up late, which can also help control the condition and prevent the occurrence of psychiatric disorders.
