Sometimes doctors work for minutes, even for a simple blood draw. Because The vein accessed for this procedure is not an ordinary vein.

Bride, Let’s look at the reasons for this annoying situation.

One of the reasons why it is so difficult to find veins: there is the depth and size of the veins, whether they are dehydrated, and people’s stress levels.

In addition, external factors such as blood collection technique and room temperature can make it difficult or easy to find veins. Temperature is very important because Surface veins are part of the body’s temperature control system.

When we are very hot, all our veins dilate, causing us to lose heat. When we are cold, our body secretes hormones that constrict blood vesselsIt reduces the diameter of the veins and makes them almost impossible to expand.

In addition to external factors, it is also possible that a person’s veins are too small and deep to be easily detected.

Patients with deeper veins under the skin, especially those with high body mass, experience significant problems during blood collection. Some people also have rolling veins. These veins It moves easily when touched and can change position when the needle is inserted.

On the other hand, stress and anxiety levels can make it harder to notice veins, as they are blood vessels in the skin while contracting as part of the ‘fight or flight’ responsethe veins that supply the muscles expand.

Again, if the person is dehydrated, It becomes difficult for doctors to find veins and draw blood. In summary, whether everything goes smoothly during blood donation depends on many variables.
