" diabetes " is one of the most common chronic diseases in my country. The existing diabetics in my country have reached nearly 120 million .
Currently, diabetes is mainly divided into type 1 and type 2. Among them, 2 diabetes is the most common, accounting for about 90% of all patients. Its disease is mainly related to factors such as genetic susceptibility genes, obesity, acquired bad diet and living habits .
Whether it is type 2 or type 1 diabetes, as long as it is confirmed, it is necessary to control the condition through medication, injecting insulin , etc. This is because the real terrible thing about diabetes is not just the continuous increase in blood sugar, but the damage to multiple target organs and tissues caused by hyperglycemia , including kidney damage, cardiovascular and cerebrovascular disease , etc.!
Data surveys show that the longer a person suffers from diabetes and has unstable blood sugar control, more or less complications will occur after the development reaches a certain stage. Therefore, in order to detect early complications, it is also recommended that people who suffer from sugar diseases all year round should undergo regular physical examinations. For example, ct is a commonly used method.
There is also a very special diagnostic method in ct, that is, "enhanced ct" . The so-called enhanced CT is clinically called enhanced CT4. It refers to the key examination of suspected lesions found on the basis of CT scan, after intravenous injection of contrast agent, thereby improving the diagnostic accuracy of the disease.
Therefore, in order to improve the accuracy of the examination, many diabetics will suggest to their doctors that they want to conduct enhanced CT screening.
So the question is, can diabetic patients undergo enhanced CT examination?
The contrast agent used for enhancement ct is actually a non-ionic contrast agent . Although is less harmful to the kidneys, it also has a small negative impact on . Because after the contrast agent enters the body, it needs to be excreted through the kidneys. Enhanced CT screening in people with poor kidney function may cause burden, resulting in the occurrence of contrast agent nephropathy ;
For many diabetic patients, years of illness and poor blood sugar control will cause damage to kidney function, and thus develop into diabetic nephropathy . If kidney disease occurs, but enhanced CT screening may continue to decline in kidney function and eventually cause fatal damage. Therefore, when diabetics undergoing enhanced ct examination, they need to screen their personal kidney function in detail;
If is found to have good kidney function and no parenchymal lesions appear in the kidney, diabetics can also do enhanced ct screening for . However, there are several issues that need to be noted:
1. Disable the medication
Before performing an enhanced ct scan, diabetics need to stop taking metformin tablets , because after this drug enters the body, needs to metabolize and excrete through the kidneys. Contrast agents that enhance CT will cause burden on the kidneys. If you have taken metformin tablets before, it will cause this type of drug to be stored in the kidneys in large quantities, increasing the risk of lactic acidosis;
2. Fasting
Usually, when performing abdominal enhancement CT scans, diabetics need to fast before examination. This is because the injection of contrast agent may cause side reactions such as nausea, vomiting, and . If you check after eating, the food may enter the trachea and even cause the risk of suffocation . Therefore, before performing an enhanced CT scan, you should strictly follow the doctor's advice!
In addition, if diabetics are accompanied by other problems such as cardiac insufficiency and cardiovascular disease, before doing enhanced CT examination, you should also fully inform the doctor of your details and communicate with the doctor to see if you are suitable for enhanced CT examination according to the doctor's advice, or to avoid affecting the heart during the examination.
