Getting thinner and thinner?


Hello Dr.
Huang: I am 168 cm tall and my weight was 58 kg a year ago, but now it has dropped to only 47 kg.
My weight has gradually decreased over the past year.
My diet is normal and my portion sizes are adequate, but I feel more fatigued.
Could this be due to the excessive stress from studying architecture last year, or could there be other reasons? If so, what are some ways to improve this? (I have seen a traditional Chinese medicine practitioner who mentioned that my liver function is not optimal.)

Jie, 20~29 year old female. Ask Date: 2000/11/15

Hello, Jie! If you have experienced a nearly 20% weight loss over the past year without intentional dieting, it is recommended that you visit a qualified medical institution, such as a Metabolism or Family Medicine department, for endocrine evaluations or related health checks.
Poor liver function requires objective and accurate data for confirmation.
It is important to pay attention to your health, especially while managing your academic workload.
Take care and maintain your weight!

More Info


Unintentional weight loss can be concerning, especially when it occurs over a relatively short period, as in your case where you have lost 11 kilograms in a year without any significant changes in your diet or lifestyle. Given your height of 168 cm and current weight of 47 kg, your Body Mass Index (BMI) is approximately 16.6, which classifies you as underweight. This can lead to various health issues, including fatigue, weakened immune function, and potential nutrient deficiencies.

There are several potential causes for unintentional weight loss, and it’s important to consider both physical and psychological factors. Here are some common causes:
1. Metabolic Disorders: Conditions such as hyperthyroidism (overactive thyroid) can increase metabolism, leading to weight loss despite normal or increased food intake. Other metabolic disorders could also play a role.

2. Gastrointestinal Issues: Problems such as malabsorption syndromes (e.g., celiac disease, Crohn's disease) can prevent your body from absorbing nutrients effectively, leading to weight loss. If you are experiencing gastrointestinal symptoms like bloating, diarrhea, or changes in bowel habits, it would be wise to consult a gastroenterologist.

3. Chronic Illness: Conditions such as diabetes, cancer, or chronic infections can lead to weight loss. These conditions often come with other symptoms, such as fatigue, fever, or changes in appetite.

4. Mental Health Factors: Stress, anxiety, and depression can significantly affect appetite and eating habits. If you have been under considerable stress, such as the demands of your architecture studies, this could contribute to your weight loss.

5. Nutritional Deficiencies: Even if you feel you are eating enough, the quality of your diet matters. A diet lacking in essential nutrients can lead to fatigue and weight loss. It’s important to ensure you are consuming a balanced diet rich in proteins, healthy fats, and carbohydrates, along with vitamins and minerals.

6. Liver Function: You mentioned that a traditional Chinese medicine practitioner indicated that your liver function is not optimal. The liver plays a crucial role in metabolism and detoxification. Impaired liver function can lead to various symptoms, including fatigue and weight loss.


Solutions and Recommendations:
1. Medical Evaluation: It is crucial to undergo a comprehensive medical evaluation. This should include blood tests to check for thyroid function, liver function, and other metabolic markers. A thorough physical examination can help identify any underlying health issues.

2. Nutritional Assessment: Consider consulting a registered dietitian who can evaluate your dietary intake and suggest modifications to ensure you are meeting your nutritional needs. They can help you create a meal plan that is calorically dense yet nutritious.

3. Stress Management: If stress is a contributing factor, exploring stress management techniques such as mindfulness, meditation, or counseling could be beneficial. Engaging in regular physical activity, even light exercise, can also help improve mood and overall well-being.

4. Regular Monitoring: Keep track of your weight and any associated symptoms. Regular follow-ups with your healthcare provider can help monitor your condition and make necessary adjustments to your treatment plan.

5. Lifestyle Adjustments: Ensure you are getting enough rest and managing your workload effectively. Sometimes, academic pressures can lead to neglecting self-care, which can exacerbate fatigue and weight loss.

In conclusion, unintentional weight loss is a multifaceted issue that requires careful evaluation and management. It is essential to address both the physical and psychological aspects of your health to achieve a balanced and healthy weight. Seeking professional medical advice is the best course of action to identify the underlying causes and develop an appropriate treatment plan.
