Fuelling Anxiety with progestogens and oestrogens Re: Margaret McCartney: We should stop fuelling anxiety

Fuelling Anxiety with progestogens and oestrogens

I agree with Margaret Mc Cartney that posters in GP surgeries, pharmacies, researchers, charities and health promotions should stop fuelling anxiety.1 However, anxiety is often due to biochemical changes caused by common GP prescriptions.

A dramatic example of anxiety is the premenstrual syndrome (PMS) when some women can suddenly experience severe anxiety.2 Women affected can rush around cleaning everything in sight or become aggressive and argumentative. They are also more likely to have traffic accidents and deaths from violence. Biochemically, levels of the enzyme monoamine oxidase (MAO) increase dramatically from as low 1000 to as high as 20 000 units for a few days only at the end of a normal cycle in the premenstrual phase.3,4 When women are prescribed progesterone dominant hormonal contraceptives, or combined HRT, MOA levels can remain high, especially with modern continuous formulations, increasing the risk of accidental deaths or suicides.3,5,6

Women are more likely to suffer from PMS or exogenous hormone mental effects if they also have abnormal zinc/copper ratios and/or red blood cell (RBC) magnesium deficiencies.7 Magnesium is known as “Nature’s Calmer”. Both men and women can have difficulty correcting cellular magnesium deficiency if it is due to too much exercise or malabsorption problems. GPs and hospitals could have RBC tests available as serum magnesium levels are often in the normal range and not helpful in this context.
