Weight loss can lead to hormonal imbalances?
Dear Dr.
Tseng,
At the end of last year, I started to lose weight gradually because I was dissatisfied with my body.
I adopted a method of eating less and exercising more, and over several months, I lost about five kilograms.
Although I did not diet, my menstrual cycle became very irregular; sometimes it was very short and light, and other times it didn't come at all.
Now that I have returned to a normal diet, my menstrual cycle is back to normal in terms of timing, but the flow is still less than before.
Additionally, I noticed that for more than a month now, my hair has been falling out rapidly.
Whether I am brushing or washing my hair, the amount of hair loss, although within the normal range of 100-200 strands, is about three times what it used to be, and there is a noticeable reduction in hair density.
I am really worried that I will have too little hair and it won't look good.
I would like to ask you: should I see a doctor, or will it improve naturally after some time? Also, are there any specific dietary considerations I should be aware of? I would greatly appreciate your guidance!

Hello, Xiao Bing: Even when dieting, it's important to meet your basic caloric needs and ensure a balanced intake of various nutrients.
If you continue to experience low menstrual flow or if the situation does not improve, please make sure to consult an endocrinologist.

More Info
Weight loss can be a challenging journey, especially when it comes to maintaining hormonal balance and overall health. Based on your experience of losing weight through a combination of reduced food intake and increased physical activity, it’s important to recognize that significant changes in diet and exercise can impact your hormonal health, menstrual cycle, and even hair health.
Firstly, it’s commendable that you have managed to lose about five kilograms over several months. This gradual approach is often more sustainable than rapid weight loss, which can lead to various health issues. However, the irregularities in your menstrual cycle and the increase in hair shedding you’ve described are concerning and warrant further investigation.
Hormonal Imbalance and Menstrual Irregularities
The menstrual cycle is regulated by a complex interplay of hormones, including estrogen and progesterone. Weight loss, especially if it is accompanied by a significant caloric deficit, can lead to hormonal imbalances. This is particularly true if your body perceives the weight loss as a form of stress, which can trigger the hypothalamus to reduce the production of hormones that regulate menstruation.
Irregular periods, such as having shorter cycles or missed periods, can be a sign of conditions like hypothalamic amenorrhea, which occurs when the body is under stress due to low energy availability. It’s crucial to ensure that your caloric intake is sufficient to support your body’s needs, especially if you are physically active.
Hair Loss Concerns
Increased hair shedding can also be linked to hormonal changes, nutritional deficiencies, or stress. When the body is under stress or not receiving adequate nutrition, it may prioritize essential functions over hair growth, leading to increased hair loss. The fact that you are experiencing hair loss at a rate that feels excessive to you is a valid concern and should be addressed.
When to Seek Medical Advice
Given the changes in your menstrual cycle and the increase in hair loss, it would be prudent to consult with a healthcare professional. A doctor can perform a thorough evaluation, which may include blood tests to check hormone levels, thyroid function, and nutritional status. They can also assess whether your weight loss strategy is appropriate for your body and health goals.
Nutritional Considerations
In terms of diet, it’s essential to focus on a balanced intake that includes adequate calories, protein, healthy fats, and carbohydrates. Consider incorporating nutrient-dense foods that support hormonal health, such as:
- Healthy Fats: Avocados, nuts, seeds, and olive oil can help support hormone production.
- Lean Proteins: Chicken, fish, legumes, and tofu can provide the necessary building blocks for hormone synthesis.
- Whole Grains: Foods like quinoa, brown rice, and oats can provide sustained energy and fiber.
- Fruits and Vegetables: These are vital for providing essential vitamins and minerals that support overall health.
Conclusion
In summary, while your approach to weight loss has been gradual and mindful, the changes in your menstrual cycle and hair health indicate that it may be time to seek medical advice. A healthcare professional can help you understand the underlying causes of these changes and guide you in making adjustments to your diet and lifestyle that promote hormonal balance and overall well-being. Remember, your health is paramount, and addressing these concerns early can lead to better outcomes in your weight loss journey and overall health.
