Levothyroxine and Mental Health: How it Affects Mood and Brain Function

Levothyroxine Mental

and Health

Levothyroxine, also known as T4, is a synthetic thyroid hormone used to treat hypothyroidism and other thyroid-related conditions. Recently, evidence has been uncovered linking levothyroxine use with mental health issues and the way the drug affects a person’s mood and brain function. This article looks into levothyroxine’s effect on mental health, brain function, and overall health.

What is Levothyroxine?

Levothyroxine is a hormone that is released by the thyroid gland and is necessary for diverse bodily functions such as metabolism, growth, and development. The hormone is responsible for regulation of hormones, metabolism, cell growth and development, cardiac output, and body temperature, as well as other vital functions. Levothyroxine is often prescribed in cases of an underactive thyroid gland or hypothyroidism in order to supplement the body’s natural production of the hormone and restore hormonal balance in the body.

Mood and Emotional Side Effects of Levothyroxine

Common side effects of levothyroxine use include tiredness, headaches, irritability and, in some cases, depression. Studies suggest that there is a link between levothyroxine and mental health, particularly depression, anxiety and other mood disorders. Research further indicates a possible link between levothyroxine and bipolar disorder. In addition, some studies point to a link between using levothyroxine during pregnancy and an increased risk of postpartum depression.

Effects of Levothyroxine on Brain Function

Research suggests a connection between levothyroxine and brain function as well, including possible cognitive deficits. Studies have indicated that levothyroxine might have an effect on people’s memory, concentration and focus. Other studies have looked into the relationship between levothyroxine and Alzheimer’s disease, suggesting a potential association, though the extent is yet unknown.

Impact of Levothyroxine on Overall Health

Levothyroxine is known to have an influence on a person’s overall health and wellness. When a person’s thyroid hormones are imbalanced due to hypothyroidism or a thyroid related condition, the body is, in general, not functioning as it should and is likely to experience a lack of energy, resulting in low physical activity. Furthermore, levothyroxine has been linked to weight gain and sleep problems, with some studies even indicating a potential link between levothyroxine and increased risk of death.
