Prolonged menstrual issues, such as experiencing a period that lasts for three weeks, can be concerning and may stem from various underlying causes. In your case, the symptoms you've described—prolonged menstruation with light bleeding, fatigue, dizziness upon standing, and recent weight loss due to dietary changes and increased physical activity—warrant a thorough evaluation.

Firstly, it is essential to understand that menstrual cycles can be influenced by numerous factors, including hormonal imbalances, stress, changes in body weight, and underlying medical conditions. Given that you have recently lost weight and increased your physical activity, these lifestyle changes could be contributing to your irregular menstrual cycle. Significant weight loss can lead to hormonal fluctuations, particularly affecting estrogen levels, which can disrupt the normal menstrual cycle and lead to prolonged bleeding.

Another potential cause of prolonged menstruation is a condition known as dysfunctional uterine bleeding (DUB), which is often related to hormonal imbalances. Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or even uterine fibroids can also lead to irregular bleeding patterns. Since you mentioned that you have not experienced any pain during your period, this may help rule out certain conditions like endometriosis, which typically presents with painful menstruation.

The dizziness and fatigue you are experiencing could be related to several factors. If your menstrual bleeding is prolonged, even if the blood loss is minimal, it can still lead to a decrease in your iron levels, potentially resulting in anemia. Anemia can cause symptoms such as fatigue, weakness, and dizziness, especially when standing up quickly. It is crucial to monitor these symptoms closely, as they can indicate a need for further medical evaluation.

To address your prolonged menstrual issues, it is advisable to consult with a healthcare provider, preferably a gynecologist. They may recommend several diagnostic tests, including blood tests to check hormone levels, a complete blood count to assess for anemia, and possibly imaging studies like an ultrasound to evaluate the uterus and ovaries for any abnormalities.

In the meantime, consider the following steps to help manage your symptoms:
1. Maintain a Balanced Diet: Ensure you are consuming enough nutrients, particularly iron-rich foods (like leafy greens, beans, and lean meats) to help prevent anemia. A balanced diet can also support hormonal balance.

2. Stay Hydrated: Drink plenty of fluids, especially if you are experiencing fatigue and dizziness. Dehydration can exacerbate these symptoms.

3. Monitor Your Symptoms: Keep a detailed record of your menstrual cycle, including the duration, flow, and any accompanying symptoms. This information can be invaluable for your healthcare provider in diagnosing the issue.

4. Rest and Manage Stress: Ensure you are getting adequate rest and managing stress, as both can impact hormonal balance and overall health.

5. Avoid Excessive Exercise: While regular exercise is beneficial, excessive physical activity, especially with inadequate caloric intake, can disrupt your menstrual cycle. Consider moderating your exercise routine if you suspect it may be contributing to your symptoms.

In conclusion, while there are several potential causes for your prolonged menstrual symptoms, a thorough evaluation by a healthcare professional is essential to determine the underlying issue and appropriate treatment. Addressing lifestyle factors, monitoring your symptoms, and seeking medical advice will be crucial steps in managing your health effectively.
