I'm sorry to hear you're experiencing night bruxism and a loss of appetite. Night bruxism, which is teeth grinding during sleep, can be caused by various factors including stress, anxiety, sleep disorders, or certain medications. A slight loss of appetite can also have many causes, ranging from infections to digestive issues or stress.

Regarding intestinal worms, they can sometimes cause symptoms like abdominal discomfort, nausea, or changes in appetite, but night bruxism is not typically associated with parasitic infections. If you suspect intestinal worms, a healthcare provider can perform stool tests to confirm the diagnosis.

There is a medication called Albendazole, which is used to treat various parasitic worm infections. However, it should only be taken after proper diagnosis and prescription by a doctor.

Recommendations:

• Consult a general physician or a gastroenterologist to evaluate your symptoms thoroughly.
• They may recommend stool tests or other investigations to rule out parasitic infections.
• If bruxism persists, a dentist or a sleep specialist might help manage it.

Please seek professional medical advice to get an accurate diagnosis and appropriate treatment. If symptoms worsen or you experience additional issues, do not hesitate to contact a doctor promptly.To narrow down potential causes, we will need some more information.I understand that you have been experiencing night teeth grinding and reduced appetite for the last two weeks.
