How long can I not eat before physical examination? If I have a physical examination in the morning, I can't eat breakfast, but what should I do in the afternoon? No breakfast or lunch?

If there is a blood and liver function test in the physical examination, you should eat light food the night before the physical examination and it is not easy to drink. You can't have breakfast if you have a B-ultrasound examination of your liver and gallbladder.

If you have a physical examination in the afternoon: If you can't insist on not eating, it is not recommended for people with hypoglycemia not to eat. Then I suggest eating early in the morning and eating something light. For example, just have some porridge.

Of course, if it is not an important physical examination but a normal physical examination, I think it is ok to eat something light in the afternoon.
