Adrenocorticotrophic hormone or ACTH is the hormone produced by the pituitary to stimulate the production of cortisol at the adrenal glands and other tissues in the body.

The hypothalamus is an area in the central nervous system or brain that produces pre-pituitary hormones to stimulate the production of hormones at the pituitary.

The thyroid gland is the master gland (located in the front of the neck) that is involved in tissue organisation and function from conception and throughout life. Whilst many facets of medicine tend to compartmentalise disease processes, the thyroid gland can be associated with many areas of body function which include:

  • Fertility

  • Hormones in general

  • Blood sugar regulation and diabetes

  • High cholesterol, high blood pressure and heart disease

  • Sleep biology

  • Weight loss and gain

  • Neurological disorders

  • Menstrual irregularities

  • Depression and anxiety

The thyroid gland is influenced by many factors such as nutrition, environmental pollutants and stress.


Thyroid stimulating hormone

TSH is a hormone that is produced by the pituitary gland in response to low thyroid hormone production. TSH is considered the gold standard for assessing thyroid function in clinical practice but some inconsistencies may cause the value to be a poor reflection of thyroid hormone status. Low carb, calorie and fads such as eating clean can impact thyroid hormone levels, as can chronic stressors and environmental pollutants, such as those found from fossil fuel combustion, air fresheners, cleaning products and plastics can suppress thyroid hormone feedback and production.





Estrogen (oestrogen UK) is a well known hormone that influences tissue growth amongst other factors. Whilst estrogen is often cited as a primary reason for menopausal symptoms in women, an excess of estrogen, from either internal or external sources have been found to be significant drivers of diseases such as cancer. It’s primary function is tissue proliferation and the increased and often unchecked growth process, through increased levels can play a significant role in lowering thyroid hormone and the anabolic and protective hormones such as progesterone and testosterone. Estrogen plays a significant role in premenstrual syndrome/tension, lowering blood sugar levels and increasing oedema and water retention. There’s no doubting that estrogen is an essential hormone but more often than not is often elevated despite blood tests showing normal concentrations.

Progesterone is a hormone that regulates tissue organisation, blood sugar regulation and helps oxygenate tissue. It’s intimately linked in maintaining gestation during pregnancy and has shown to be useful for resolving morning sickness/toxemia of pregnancy, post natal depression and traumatic brain injury among others. Progesterone can be suppressed during stress and low food intake.
