Qué es la perimenopausia y cómo reconocerla
Duermes peor, la regla es menos predecible, tu ánimo sube y baja, y los análisis salen «bien». ¿Te suena? Muy a menudo detrás de todo esto está la perimenopausia: los años de transición antes de la última regla. No es una enfermedad, sino una etapa por la que pasa cada mujer. Pero apenas se habla de ella, y por eso muchas mujeres pasan años sin entender qué les ocurre.
Qué pasa en el cuerpo
En la transición, las hormonas no cambian de forma suave ni todas a la vez.
La progesterona baja primero, y de forma constante. Después de los 40, cada vez más ciclos ocurren sin ovulación, y esto es una parte normal de la transición. La progesterona alimenta el «calmante» natural del cerebro, por eso su descenso suele notarse como dificultad para conciliar el sueño.
El estrógeno, mientras tanto, no baja: oscila. Unas veces baja, otras sube por encima de lo habitual, y solo después desciende de forma definitiva. Lo que más altera cómo te sientes en estos años es la amplitud de esas oscilaciones, no el nivel en sí. De ahí la sensación de que «nada tiene sentido»: una semana va bien y la siguiente es difícil.
Cómo reconocerla
La perimenopausia se reconoce por un cuadro que se va formando con el tiempo, no por un solo análisis. Señales típicas:
- El ciclo cambia. Entre los 35 y los 50, la regla a menudo se vuelve más abundante, más larga o más irregular.
- El sueño. Cuesta más dormirse, te despiertas más por la noche, la mente «no se apaga».
- El ánimo. Altibajos, irritabilidad; los días antes de la regla se notan más que antes.
- Pecho y líquidos. Pecho hinchado y sensible, hinchazón.
- La cabeza. Migrañas, «niebla mental», peor concentración.
- Sofocos y sudores nocturnos. Pueden empezar ya en estos años.
No hace falta tenerlo todo a la vez. Importa más el patrón: qué se repite y cómo se relaciona con el ciclo.
Qué hacer primero
Empieza a registrar. El primer día de la regla, el sueño, los sofocos, el ánimo: cada día, brevemente. En unas semanas verás relaciones que la memoria no retiene. Ese es el mejor «análisis» de la transición.
Pon un ancla al sueño. Levántate a la misma hora los siete días de la semana, fines de semana incluidos, y toma 10–15 minutos de luz natural en la primera hora tras levantarte. Es la palanca de conducta más fuerte para el sueño, más que cualquier suplemento.
Quita lo que altera la noche. Café y té fuerte, antes de las 14:00; por la noche, sin alcohol: da sueño, pero corta la segunda mitad de la noche.
Revisa el hierro si tus reglas son abundantes. Las reglas abundantes son la causa más frecuente de falta de hierro en las mujeres, y sus reservas bajan antes de que cambien los análisis de sangre habituales. Cansancio, falta de aire al subir escaleras, caída del pelo: motivo para pedir a tu médico un análisis de ferritina. El hierro, según el análisis, no a ciegas.
Cuándo ir al médico sin esperar
- Tienes que cambiar la compresa o el tampón cada hora durante varias horas seguidas.
- La regla dura más de 8 días.
- Sangrado entre reglas.
- Sangrado junto con mucho cansancio o mareo.
No es «solo la transición»: estas señales hay que enseñárselas al ginecólogo.
Qué probar esta semana
- Anotar en VIA-L el primer día de la regla y el sueño.
- Levantarte a la misma hora los siete días.
- Café antes de las 14:00, noche sin alcohol.
