Study Notes

Menstruation is a physiological process that occurs in women between the ages of menarche and menopause. It is a complex cycle controlled by hormones and glands, and is characterized by the shedding of the uterine lining through the vagina. The menstrual cycle typically lasts between 21 and 35 days, with an average of 28 to 38 days. It consists of four phases: menstruation, the follicular phase, ovulation, and the luteal phase.

Menstruation

Menstruation is the first phase of the menstrual cycle, occurring after the start of puberty. During this phase, the uterine lining, or endometrium, sheds and is expelled from the body through the vagina. The average length of a period is three to seven days, but it can vary greatly from person to person. Common symptoms during menstruation include cramping, bloating, and mood changes.

Follicular Phase

The follicular phase begins on the first day of menstruation and lasts for approximately 13 to 14 days, ending in ovulation. During this phase, the pituitary gland releases a hormone that stimulates the growth of follicles on the surface of the ovary. Typically, only one follicle will mature into an egg, which can happen around day 10 of the cycle. The uterine lining also thickens during this phase in preparation for a potential pregnancy.

Ovulation

Ovulation is the process by which a mature egg is released from the ovary and moves into a fallopian tube on its way to the uterus. This usually occurs around two weeks before the next period. Ovulation can last from 16 to 32 hours, and it is during this period that fertilization can occur if sperm is present.

Luteal Phase

After ovulation, cells in the ovary, known as the corpus luteum, release progesterone and a small amount of estrogen. These hormones cause the uterine lining to thicken in preparation for the potential implantation of a fertilized egg. If a fertilized egg implants in the uterine lining, the corpus luteum continues to produce progesterone, which maintains the thickened lining. If pregnancy does not occur, the corpus luteum dies and the uterine lining sheds, leading to another menstruation cycle.

Common Menstrual Problems

Common menstrual problems include heavy or painful periods, premenstrual syndrome (PMS), and irregular periods. PMS can cause hormonal events before a period, leading to symptoms like fluid retention, headaches, fatigue, and irritability. Treatment options for these problems include exercise, dietary changes, and medication.

In conclusion, menstruation is a normal physiological process that involves the shedding of the uterine lining. It is part of a larger, complex cycle that prepares the body for pregnancy. Understanding the phases of the menstrual cycle and common menstrual problems can help individuals better manage their periods and associated symptoms.
