How long after the physical examination can I eat normally

After the physical examination, normal diet can generally be resumed immediately, and the specific time depends on the examination items. The ability to eat immediately after a physical examination mainly depends on the type of examination. If there is no symptom of hypoglycemia or needle fainting after blood sampling, you can usually eat in 5-10 minutes. It is recommended to give priority to foods that are easy to digest, such as bread and Congee. After undergoing gastroscopy, fasting for 2-4 hours is required. After the anesthetic effect subsides, warm water can be consumed first, and there should be no coughing reaction before gradually transitioning to a liquid diet. After non-invasive examinations such as X-rays and B-ultrasound are completed, normal eating can be carried out directly, but overeating should be avoided. Some special examinations, such as glucose tolerance tests, require fasting for 4-6 hours and complete the entire blood collection process before eating. Individuals with chronic diseases who require regular medication should adjust the interval between medication and meals under the guidance of a doctor. After the physical examination, it is important to choose light and nutritious foods to avoid a high-fat and high sugar diet that can increase the burden on the gastrointestinal tract. High quality protein such as eggs and fish can be supplemented in moderation, paired with fresh vegetables and fruits to promote metabolism. postoperative patients or special subjects should strictly follow the dietary plan formulated by the doctor's advice. If you experience dizziness, nausea, or other discomfort after eating, you should immediately stop eating and contact medical staff at the examination institution.
