Patients with trigeminal neuralgia need to be cautious about their diet. In daily life, try to avoid oily, spicy, and irritating foods, as these types of foods may trigger an attack of trigeminal neuralgia or make the existing attacks more frequent, thereby causing great pain to the patient. It is recommended to choose a light diet in daily life, low in salt and fat, especially for patients with high blood pressure or diabetes, who need to be more cautious. It may be beneficial to appropriately include some fresh vegetables and fruits in the diet, and it is also suggested to supplement with some multivitamin drugs, which might enhance the effects. If trigeminal neuralgia attacks frequently, it is still recommended to visit a local hospital in a timely manner and consider undergoing microvascular decompression surgery for treatment.
