Several factors can contribute to oligomenorrhea in adolescents. These include: - Hormonal Imbalances: During puberty, the body undergoes significant hormonal changes, which can lead to irregular menstrual cycles. - Polycystic Ovary Syndrome (PCOS): This is a common endocrine disorder that can cause oligomenorrhea due to an imbalance of reproductive hormones. - Stress and Eating Disorders: High levels of stress or conditions such as anorexia nervosa and bulimia can disrupt the normal menstrual cycle. - Intense Physical Activity: Athletes or those engaged in high levels of physical activity may experience oligomenorrhea due to energy deficits and hormonal changes. - Thyroid Disorders: Both hypothyroidism and hyperthyroidism can affect menstrual regularity.
