Hi,
How are you? Are there other symptoms present? Trembling, fatigue and headaches after meals may be caused by postprandial hypoglycemia or reactive hypoglycemia. To verify this diagnosis, you need to check your blood sugar level ( a blood glucose level that falls below 70mg/dL). This condition usually occurs in individuals who do not have diabetes. Associated symptoms include sweating, dizziness, anxiety, confusion, weakness and difficulty with speech. Small frequent meals, a healthy weight, less of sugary carbohydrates but more of fruits and vegetables may help. If it persists, check with your doctor for proper evaluation., Take care and best regards.
