Adolescent Health: Understanding Menstruation

Definition: According to the World Health Organization (WHO), menstruation is the regular natural process of shedding blood and tissue from the uterus through the vagina as part of the menstrual cycle.
Menarche: The first occurrence of menstruation, typically beginning between the ages of $9$ and $16$ years, usually $2-3$ years after breast development begins.
Cycle Duration: In teenagers, cycles range from $21$ to $45$ days.
Flow Duration: Menstrual periods generally last between $3$ and $7$ days, with bleeding typically lasting $2$ to $7$ days.

1. Menstrual Phase (Day 1-5): Marks Day $1$ of the cycle. The uterine lining (endometrium) is shed because no pregnancy occurred. Hormone levels of oestrogen and progesterone are low.
2. Follicular/Proliferative/Regenerative Phase (Day 1-13): The pituitary gland releases FSH (follicle-stimulating hormone), stimulating ovarian follicles. Typically, one dominant follicle matures into an egg.
3. Ovulation Phase: Triggered by a surge in LH (luteinizing hormone), the mature egg is released from the ovary into the fallopian tube. This is the most fertile window.
4. Luteal Phase/Secretory: The ruptured follicle becomes the corpus luteum, secreting progesterone to maintain the uterine lining. If fertilization does not occur, hormone levels drop and the lining breaks down.

Physical Symptoms: Includes headaches, pelvic pain, fatigue, bloating or gassy feelings, breast soreness, and acne flare-ups.
Emotional Symptoms: Includes irritability, mood swings, insomnia, brain fog, changes in sex drive, appetite fluctuations, and anxiety or crying spells.
