Irregular menstruation can be a source of significant distress for many individuals, and it can stem from a variety of causes. Given your symptoms—irregular menstrual cycles, changes in the volume of menstrual flow, prolonged bleeding, and discomfort in the lower abdomen—it is essential to consider several potential factors that could be contributing to your situation.

Firstly, your height and weight indicate a body mass index (BMI) that is on the lower end of the spectrum. Low body weight can indeed affect menstrual regularity. The body requires a certain amount of body fat to produce hormones that regulate the menstrual cycle. When body fat is too low, it can lead to hormonal imbalances, which may result in irregular periods or even amenorrhea (the absence of menstruation). This is particularly common in individuals who are underweight or have eating disorders.

Hormonal imbalances are another common cause of irregular menstruation. Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders (both hyperthyroidism and hypothyroidism), and other endocrine issues can lead to irregular cycles. PCOS, in particular, is characterized by irregular periods, excess androgen levels, and polycystic ovaries, which can also lead to symptoms such as increased body hair and acne.

The presence of brown discharge and prolonged menstrual bleeding could indicate other underlying issues, such as endometriosis or uterine fibroids. Endometriosis occurs when tissue similar to the lining of the uterus grows outside of it, leading to pain and irregular bleeding. Fibroids are noncancerous growths in the uterus that can cause heavy bleeding and discomfort.

In addition to these conditions, stress and lifestyle factors can also play a significant role in menstrual irregularities. High levels of stress can disrupt the hypothalamus, which regulates the hormones responsible for menstruation. Changes in physical activity, diet, and sleep patterns can also impact your cycle.

Given your symptoms, it is advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, which may include a physical examination, blood tests to check hormone levels, and possibly imaging studies such as an ultrasound to assess the reproductive organs. This comprehensive approach will help identify any underlying conditions that may be contributing to your irregular menstruation.

In terms of management, treatment will depend on the underlying cause identified by your healthcare provider. If your irregular menstruation is related to low body weight, a nutritionist may recommend a balanced diet to help you reach a healthier weight. Hormonal treatments, such as birth control pills, may be prescribed to regulate your cycle if hormonal imbalances are identified. Additionally, lifestyle modifications, including stress management techniques and regular exercise, can also be beneficial.

In conclusion, while your symptoms may be concerning, they are not uncommon, and many effective treatments are available. It is essential to consult with a healthcare professional who can provide personalized advice and treatment options based on a thorough assessment of your health. Taking this step will not only help address your menstrual irregularities but also improve your overall well-being.
