Menstruation

Menstruation — is a part of the menstrual cycle during which the functional layer of the endometrium is rejected and blood is released from the uterine cavity. This process reflects the cyclical hormonal changes in a woman’s body and is associated with the preparation of the reproductive system for possible conception.

The average duration of the menstrual cycle ranges from 21 to 35 days; however, it can vary among different women.

Phases of the Menstrual Cycle

The menstrual cycle consists of sequential phases, each accompanied by characteristic hormonal and physiological changes:

1. Follicular phase — begins on the first day of menstruation; the production of follicle-stimulating hormone increases in the pituitary gland, follicles mature in the ovaries, and estrogen levels gradually rise;
2. Ovulation — the rupture of the mature follicle occurs, and the egg is released from the ovary; this period is characterized by a peak in luteinizing hormone and is the most favorable for conception;
3. Luteal phase — after ovulation, the corpus luteum forms, which produces progesterone; the hormone prepares the endometrium for possible embryo implantation; if fertilization does not occur, hormone levels decrease, and the next menstruation begins.

Symptoms of Menstruation

During menstruation, various physiological and emotional manifestations may occur. Their intensity depends on individual characteristics of the body and hormonal background:

• Pain or cramps in the lower abdomen;
• Mood changes and irritability;
• Increased sensitivity of the breasts;
• Feelings of fatigue or reduced energy;
• Headaches;
• Abdominal bloating or fluid retention.

Menstrual Cycle and Health Status

The regularity and nature of the menstrual cycle often reflect the overall state of the hormonal system. Stress, significant changes in body weight, intense physical activity, sleep disturbances, as well as various endocrine and gynecological conditions can affect the duration and stability of the cycle.

Changes in cycle duration, absence of menstruation, or pronounced pain may be associated with hormonal disorders, polycystic ovary syndrome, endometriosis, and other conditions; therefore, it is recommended to consult a specialist in case of persistent deviations.

Factors Affecting the Severity of Symptoms

The intensity of menstrual symptoms is largely determined by hormone levels, the state of the nervous system, and the body’s nutrient supply:

• Levels of progesterone and estrogens in the luteal phase;
• Balance of prostaglandins affecting uterine contractions;
• Magnesium, B vitamins, and other nutrient availability;
• Stress levels and sleep quality;
• Overall level of physical activity.

Relief of Symptoms

Some measures can help reduce discomfort during menstruation and maintain a normal cycle:

• Heat on the abdominal area to reduce cramps;
• Moderate physical activity;
• Sufficient fluid intake;
• Balanced nutrition with adequate protein and micronutrients;
• Maintaining a regular sleep schedule.

Conclusion

Menstruation is a natural physiological process and an important indicator of the functioning of the reproductive system.

Monitoring the duration of the cycle, the nature of menstruation, and accompanying symptoms helps to better understand the state of the body and timely notice possible changes.
