Causes of changes in menstrual cycle. These changes can indicate underlying conditions like PCOS, thyroid problems, uterine fibroids, perimenopause, or specific medications and infections, but they can also be brought on by common life events like stress, weight fluctuations, exercise, pregnancy, breastfeeding, and hormonal birth control. Changes are frequent, particularly in the first few years of periods or as you approach menopause, because hormonal fluctuations, lifestyle variables, and health issues all play a key role in regulating the cycle.
CAUSES OF CHANGES IN MENSTRUAL CYCLE
Changes in the menstrual cycle can be brought on by a number of things, from underlying medical issues to stress and lifestyle modifications. It’s crucial to speak with a healthcare professional if you observe notable or ongoing changes in your menstrual cycle in order to rule out any serious problems and to talk about how to manage or resolve these changes. You can take proactive measures to preserve your reproductive health by being aware of the elements that affect your cycle.
1. Stress;

CAUSES OF CHANGES IN MENSTRUAL CYCLE
Stress is one of the most common reasons for changes in the menstrual cycle. High levels of stress can disrupt the balance of hormones like cortisol and adrenaline, which can, in turn, affect the hormones that regulate the menstrual cycle. This can lead to delayed or skipped periods.

CAUSES OF CHANGES IN MENSTRUAL CYCLE
Significant changes in body weight, whether weight gain or loss, can impact menstrual cycles. Body fat plays a role in estrogen production, and too much or too little body fat can lead to irregular periods. Extreme dieting or eating disorders can also cause menstruation to stop altogether, a condition known as amenorrhea.
3. Exercise;
Intense physical activity, especially when combined with low body fat, can disrupt the menstrual cycle. Athletes, particularly those in endurance sports, may experience irregular periods or amenorrhea due to the strain on the body and changes in hormone levels.
4. Hormonal Birth Control;

CAUSES OF CHANGES IN MENSTRUAL CYCLE
Hormonal contraceptives, such as birth control pills, patches, or intrauterine devices (IUDs), can alter the menstrual cycle. These methods work by changing the natural hormone levels in the body to prevent ovulation, which can lead to lighter, less frequent, or even absent periods.
5. Polycystic Ovary Syndrome;

PCOS is a hormonal disorder that affects many women of reproductive age. It causes irregular menstrual cycles, often due to higher levels of androgens (male hormones) and insulin resistance. Women with PCOS may experience infrequent periods, prolonged periods, or even the absence of menstruation.
6. Thyroid Issues
The thyroid gland plays a crucial role in regulating metabolism and hormone production. Both hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid) can lead to changes in the menstrual cycle, such as irregular periods or heavier bleeding.
7. Perimenopause;

As women approach menopause, typically in their late 40s to early 50s, their menstrual cycles often become irregular. This transitional phase, known as perimenopause, is marked by fluctuating hormone levels, leading to changes in cycle length, flow, and symptoms.
Summary
Hormones control the intricate menstrual cycle, which varies greatly from woman to woman. Although the average cycle lasts about 28 days, its duration and regularity can vary depending on a number of factors. Changes in the menstrual cycle can be caused by the following important factors above.
