What is the effect of eating breakfast on physical examination

I believe that before the physical examination, the doctor will advise everyone to go for the examination on an empty stomach, because this will not affect the results of the examination. However, since not eating in the morning will make a person feel very uncomfortable, some people can't help but eat breakfast. After eating breakfast, some substances in it will remain in the human blood and affect physical examination indicators. So let me introduce to you what impact eating breakfast will have on physical examination indicators.

1. The impact of eating breakfast on physical examination

A person's blood pressure and other laboratory test indicators will change throughout the day with activity and dietary factors. For example, blood sugar will rise and the gallbladder will contract within 2 hours after a meal; intestinal gas will increase after activity and affect the development of the pancreas and kidneys. These factors will affect the results of the physical examination, so the physical examination must be performed in the morning and on an empty stomach.

2. Things to note when taking a physical examination

1. Please make an appointment for the physical examination in advance; avoid drinking alcohol the day before the physical examination, limit high-fat and high-protein diet, and avoid using drugs that may affect liver and kidney function.

2. Three to five days before the examination, you should eat a light diet and avoid bloody foods such as pig liver and pig blood. After midnight on the night before the examination, please fast completely (including drinking water).

3. Blood drawing and B-ultrasound of liver and gallbladder must be performed on an empty stomach. When doing B-ultrasound of bladder, prostate, uterus and appendages, please do not urinate. If you cannot urinate, you need to drink water until your bladder is full.

4. When undergoing X-ray examination, it is advisable to wear cotton underwear and avoid wearing clothes or bras with metal buttons; please remove necklaces, mobile phones, pens, keys and other metal objects. Pregnant or potentially pregnant female examinees should inform the health checkup service personnel in advance and be cautious when undergoing X-ray examinations.

5. Women should not undergo gynecological examinations and urine tests during their menstrual period; the bladder should be emptied before a gynecological examination; and the best time to do a far-infrared breast examination is within one week after the menstrual period. Unmarried women should not undergo gynecological examinations. Those with special needs must sign a relevant agreement (notice) before they can undergo the corresponding examinations.
