Findings from a recent study published in the European Journal of Pharmacology may explain why Raynaud’s is more common in women of childbearing age. The study examined the relationship between palm blood flow and estrogen in mice. According to researchers, “estrogen may contribute to the development of Raynaud’s phenomenon in women”.
Estrogen is a one of two main sex hormones that women have. It is responsible for female physical features and reproduction. Estrogen creates the changes common in puberty, such as growth of the breasts, hair in the pubic area and under the arms and the beginning of menstruation. The hormone helps control the menstrual cycle, protect bone health and keep cholesterol in control. Below is a helpful infographic Hormone Health Network to help you understand what estrogen is.

Raynaud’s phenomenon is a condition in which there is an exaggerated blood vessel tightening in response to cold or emotional stress, restricting blood flow to certain areas of the body – most often the fingers, but sometimes the toes, ears, or the end of the nose.
The exaggerated vascular response (tightening) in Raynaud’s phenomenon is called vasospasm, which often occur in response to cold or emotional stress. With vasospasm, the fingers turn white and cold then blue with dilated veins followed by relaxation of the vessel and normal blood flow causing a red ‘flushing’
According to a recent article published in The New England Journal of Medicine, Raynaud’s affects approximately 3 to 5 percent of the population – women are more often affected than men. Raynaud’s phenomenon occurs in two forms – primary and secondary. Primary is the most common and has no underlying cause. Secondary is when Raynaud’s phenomenon occurs in combination with another autoimmune disease like scleroderma, rheumatoid arthritis, Sjogren’s syndrome or systemic lupus erythematous. The article also states that people who work with certain chemicals, like vinyl chloride, or vibrating tools like a jackhammer are also susceptible to secondary Raynaud’s. Continue reading
