Hi, It s possible that your son s anxiety and difficulty with eating are related. Anxiety can cause physical symptoms, including nausea and loss of appetite, which may be contributing to his difficulty with eating. It s good that you re working with your son s doctor on this issue. They will be able to help determine the underlying cause of his symptoms and develop a treatment plan. It s important to rule out any medical conditions that could be causing his symptoms, such as gastrointestinal problems or an eating disorder. In the meantime, there are some things you can do to help your son. Encourage him to eat smaller, more frequent meals throughout the day instead of three large meals. This can help him avoid feeling too full or uncomfortable while eating. It may also be helpful to encourage him to eat slowly and to take breaks during meals to help manage his symptoms. Additionally, you may want to explore relaxation techniques with your son to help manage his anxiety. Techniques such as deep breathing, progressive muscle relaxation, and mindfulness meditation can be helpful for reducing anxiety and stress. Remember, it s important to continue working with your son s doctor to determine the underlying cause of his symptoms and develop a comprehensive treatment plan. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Diwashish Biswas, Internal Medicine Specialist
