Weight Loss: When to Seek Medical Advice for Anxiety-Related Changes - Internal Medicine

Weight loss


Before graduating from junior high school, my weight was around 57 kilograms.
By high school and college, I gradually gained weight, fluctuating between 65 and 66 kilograms.
On January 20, I weighed approximately 66.2 kilograms.
In the following two to three weeks, due to anxiety, my appetite decreased, and my weight dropped to about 64.4 kilograms.
After school started, I slowly returned to normal eating habits and mood, and today, February 26, I weigh about 64.2 kilograms.
I would like to ask the doctor if I need to see a physician.
I am concerned that my anxiety might start again.
Additionally, since I have a tendency to be underweight (I'm not sure if my activity level at school has increased), could it be possible that I am fluctuating around 64 kilograms due to anxiety after losing weight?

Hello, whether this weight change is normal depends on food intake and exercise levels.
If the food intake is normal but weight decreases by more than 10%, it is advisable to consider a detailed examination at a family medicine clinic.
Thank you for your question.

When it comes to weight loss associated with anxiety, it is essential to understand the underlying factors that contribute to these changes and when it might be necessary to seek medical advice. In your case, you have experienced a decrease in weight from approximately 66.2 kg to around 64.2 kg due to anxiety, which has also affected your appetite. This situation raises several important considerations.

Firstly, it is crucial to recognize that anxiety can significantly impact both appetite and weight. Many individuals experience a loss of appetite when they are anxious, leading to unintentional weight loss. In your case, a drop of about 1.8 kg over a few weeks is notable but may not be alarming if it is a temporary response to stress. However, if this weight loss continues or if you experience additional symptoms such as fatigue, persistent sadness, or changes in sleep patterns, it would be wise to consult a healthcare professional.

The general guideline for seeking medical advice regarding weight loss is if you lose more than 5% of your body weight in a month without trying. In your situation, the weight loss is approximately 2.7% of your body weight, which is below this threshold. However, the context of your anxiety and its impact on your eating habits is critical. If you find that your anxiety is recurring or worsening, it may be beneficial to speak with a healthcare provider. They can help assess whether your anxiety is becoming a more significant issue that requires intervention, such as therapy or medication.

Moreover, it is essential to consider your overall health and well-being. If you have a history of being a "naturally thin" person, fluctuations in weight may be more common for you. However, if you notice that your weight is consistently below what you consider healthy or if you feel that your anxiety is affecting your daily life, it is advisable to seek help. A healthcare provider can perform a thorough evaluation, including a physical examination and possibly lab tests, to rule out any underlying medical conditions that might be contributing to your weight loss.

In addition to seeking medical advice, there are several self-care strategies you can implement to help manage anxiety and maintain a healthy weight. These include:
1. Regular Eating Schedule: Try to establish a routine for meals and snacks, even if you do not feel particularly hungry. Eating small, nutritious meals throughout the day can help maintain your energy levels and prevent further weight loss.

2. Mindfulness and Relaxation Techniques: Practices such as meditation, yoga, or deep-breathing exercises can help reduce anxiety and improve your overall mental health.

3. Physical Activity: Engaging in regular physical activity can help alleviate anxiety and improve your mood. It can also stimulate appetite, which may help you regain any lost weight.

4. Social Support: Connecting with friends, family, or support groups can provide emotional support and help you feel less isolated in your experiences.

5. Professional Help: If your anxiety persists or worsens, consider seeking help from a mental health professional. Therapy can provide you with coping strategies and tools to manage anxiety effectively.

In conclusion, while your current weight loss may not necessitate immediate medical attention, it is essential to monitor your mental health and seek help if your anxiety continues to impact your appetite or overall well-being. Taking proactive steps to manage your anxiety and maintain a healthy lifestyle can significantly improve your quality of life. If you have any concerns or if your situation changes, do not hesitate to reach out to a healthcare provider for guidance and support.
