What can cause a woman to miss her menstrual cycle other than pregnancy?

1. Stress

Stress can affect the hypothalamus, which is a part of the brain that controls the pituitary gland. The pituitary gland then releases hormones that control the ovaries, which are responsible for the menstrual cycle. When a woman is under stress, her hypothalamus can release too much or too little of these hormones, which can lead to irregular periods or missed periods.

2. Weight gain or loss

Significant weight gain or loss can also affect the menstrual cycle. When a woman gains or loses a lot of weight, her body may not produce enough of the hormones that control the menstrual cycle. This can lead to irregular periods or missed periods.

3. Thyroid problems

The thyroid gland is a gland located in the neck that produces hormones that control metabolism. When the thyroid gland is not functioning properly, it can lead to a number of health problems, including irregular periods or missed periods.

4. Polycystic ovary syndrome (PCOS)

PCOS is a hormonal disorder that affects women of childbearing age. PCOS can cause a number of symptoms, including irregular periods, acne, weight gain, and infertility.

5. Endometriosis

Endometriosis is a condition in which tissue from the lining of the uterus (the endometrium) grows outside of the uterus. Endometriosis can cause a number of symptoms, including pain, irregular periods, and missed periods.

6. Perimenopause

Perimenopause is the time in a woman's life when she is transitioning from being able to have children to not being able to have children. Perimenopause can cause a number of symptoms, including irregular periods, hot flashes, and night sweats.

7. Certain medications

Some medications, such as birth control pills, chemotherapy, and antidepressants, can cause irregular periods or missed periods.
