Menopause01:28

Menopause

158
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

369
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Stress Prevention and Stress Management Techniques VI

32
Adopting a healthier lifestyle often requires overcoming significant challenges, but leveraging psychological, social, and cultural resources can facilitate meaningful change. Effective self-change hinges on understanding and applying key tools such as motivation and goal setting, which help sustain efforts toward long-term health benefits.
Motivation and Self-Determination
Motivation, the driving force behind behavior, plays a pivotal role at every stage of the change process. The research...

Hormonal Control of the Ovarian Cycle01:30

Hormonal Control of the Ovarian Cycle

496
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle.  At puberty, GnRH secretion increases in both frequency and...

The Menstrual Cycle01:19

The Menstrual Cycle

815
The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a...

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

392
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Área de la Ciencia:

  • Salud de las mujeres
  • Endocrinología Reproductiva
  • Salud pública

Sus antecedentes:

  • La menopausia es un evento biológico universal que afecta a casi mil millones de mujeres posmenopáusicas en todo el mundo.
  • Las experiencias individuales de la menopausia son muy variables, influenciadas por los síntomas, los factores psicológicos, sociales y contextuales.
  • Los enfoques actuales a menudo se centran en el tratamiento de los síntomas en lugar de una visión holística de la transición a la menopausia.

Objetivo del estudio:

  • Proponer un modelo novedoso basado en el empoderamiento para apoyar a las mujeres durante la transición a la menopausia.
  • Cambiar la perspectiva de la menopausia como una deficiencia endocrina a una etapa de la vida que requiere un apoyo integral.
  • Abogar por un enfoque centrado en el paciente en el que los individuos sean socios activos en la gestión de su atención.

Principales métodos:

  • Este documento presenta un marco conceptual basado en la definición de empoderamiento de la Organización Mundial de la Salud.
  • Se aboga por un cambio de paradigma en la atención de la menopausia, integrando factores individuales y contextuales.
  • El enfoque hace hincapié en la toma de decisiones compartida y la experiencia del paciente.

Principales resultados:

  • El modelo de empoderamiento propuesto reconoce la naturaleza multifacética de las experiencias de la menopausia.
  • Destaca la importancia de los factores modificables en la configuración de las transiciones de las mujeres.
  • Este modelo posiciona a los trabajadores de la salud como facilitadores que apoyan la autogestión del paciente.
