Bioidentical hormone therapy

Bioidentical hormone therapy (BHT), also known as bioidentical hormone replacement therapy (BHRT), is a term referring to the use of hormones that are identical, on a molecular level, to the hormones produced by the human body. These therapies are often used as an alternative to hormone replacement therapy (HRT) in the treatment of menopausal symptoms.

History

The concept of bioidentical hormone therapy dates back to the 1930s, when it was first introduced as a treatment for menopausal symptoms. The term "bioidentical" was coined to differentiate these hormones from those used in traditional HRT, which are often derived from the urine of pregnant horses and other non-human sources.

Use and effectiveness

Bioidentical hormone therapy is most commonly used in the treatment of symptoms associated with menopause, such as hot flashes, night sweats, mood changes, and vaginal dryness. It may also be used in the treatment of other conditions that are associated with hormone imbalance, such as osteoporosis, depression, and certain forms of cancer.

While some studies have suggested that bioidentical hormone therapy may be more effective than traditional HRT in relieving menopausal symptoms, the overall evidence is inconclusive. The Food and Drug Administration (FDA) has not approved any bioidentical hormones except for one form of progesterone.

Risks and side effects

Like all forms of hormone therapy, bioidentical hormone therapy carries potential risks and side effects. These may include an increased risk of blood clots, stroke, and certain types of cancer. Side effects can include bloating, mood swings, and acne. It is important for individuals considering bioidentical hormone therapy to discuss these risks with their healthcare provider.

Controversies

The use of bioidentical hormone therapy is controversial. Some healthcare providers and organizations, including the American Medical Association and the Endocrine Society, have expressed concerns about the safety and effectiveness of these therapies. They argue that the hormones used in BHT are not regulated by the FDA, and that there is a lack of scientific evidence supporting their use.
