Menopause hot flashes

The lack of estrogen play the main and the most explained cause for menopause hot flashes , and it is explained by estrogen with drawal theory . Estrogen withdrawal theory , as in normal female body before menopause there is apart normal human brain that part called hypo thalamus, in hypothalamus there is a center called thermo regulation center that is responsible for our body temperature which is always set at our body set point 37 C , that is the thermo state of our normal body , if any thing change that set point to high or low the hypo thalamus start to send message by special neurotransmitter to the body to change its temperature by being low or high , and all that operation called thermo regulation of the body . Menopause hot flashes, the lack of estrogen disturb the normal thermo regulation operation, which result in change the menopause female’s set point in the hypothalamus from 37 to 5 or 6 grades higher, so the body feel cold and hypothalamus starts to send messages to the body to make it’s temperature higher and that message sent by special neurotransmitters , mainly adrenaline and nor adrenaline , also prostaglandin’s and serotonin , that lead to these annoying flashes ,and it’s consequences which is mainly on the heart and skin

Heart start to pump faster, to increase it’s blood out put, and so the heart rate increase , that explain the accompanied tachycardia or increase heart beating, Skin on skin blood vessels , dilatation of them as it is away to cool the body after that stimulation had gone , leave the body red and that explain the flush (redness coloration) occur after the flashes. Second on skin sweat glands, It become hyper stimulated, that lead to increase sweat production, also to cool the body , that also explain the sweats accompanied with hot flashes.

It is a natural biological process, in which there is absence of normal menstrual period for 12 consecutive months, also it is the time in a woman’s life when the function of the ovaries ceases , which lead to decrease in production of estrogen and progesterone and so no production of female egg , and women become infertile.

That is differ from Perimenopause (time around menopause) as it mean the hormonal changes associated with menopause actually begin prior to the last menstrual period , when women experience of menopausal symptoms.

Menopause is divided into two main parts , Natural menopause , and that defined above and surgical menopause , which defined as, menopause induced by the removal of the ovaries. Women who have had surgical menopause often have a sudden and severe onset of the symptoms of menopause.

Physiological basis of menopause

  1. The normal menstrual period occur due to :
  • good functioning hypothalamus in the brain
  • good functioning pituitary glands
  • good functioning ovaries
  • functioning feedbacks between hypothalamus , pituitary and ovaries

With the onset of the puberty,

The hypothalamus start to produce GnRh (gondotropin releasing hormone ) in pulstile manner , that reach the

Anterior pituitary, which become stimulated and release two types of hormones

  • FSH ( follicular stimulating hormone )
  • LH (leutinizing hormone )

These hormones reach the ovaries in two main times, Early in the cycle ( FSH mainly released ), Mid cycle ( LH mainly released )

The ovaries respond by releasing estrogen early and both estrogen and progesterone in mid cycle and that lead to formation and release of the ovum and so pregnancy may occur or normal menses occur if there is no fertilization

The menopause occur due to :

There is aging of ovaries that lead to :

  • No response to the hormones released from the brain ( hypothalamus and pituitary )
  • Decrease or even absence of storing numbers of ova inside ovaries

Which leads to:

  • Maximum decrease of circulating estrogen hormone in female body
  • Increase anterior pituitary and hypothalamic hormones

Thats finally lead to appearance of menopause symptoms and signs .

Menopause symptoms

The symptoms of the two main categories Natural & surgical menopause are the same, but there is difference in the time , severity, duration and the adaptation for these symptoms , and that difference result from , In natural menopause , there are gradual decrease in female estrogen and progesterone and that give the body chance to accommodate to that hormonal reduction , and usually it occur to old female , which psychologically can adapt to these symptoms, with complete difference in surgical menopause as there is sharp cut off of female hormones, and so there is no chances for the body to accommodate and also if it occur to young female in the beginning of her fertile age , it is completely depressive and that of course lead to more wording in body accommodation and make the symptoms more severe.
