Why Insulin Injections Don’t Draw Blood?

Hey guys , I’m back with a Bang!!! um..more accurately a minor ping!!! cause this time we are gonna talk about Injections. Why this sudden interest in injections ????? Well,  my Grandfather, whom I love a lot suddenly fell ill, a stroke along with diabetes and a broken leg (he literally fell), and is now forced to take insulin every single day. Now listen he is old and his stroke has affected his right hand pretty hard. So I stepped up and became my grandpa’s IAS (Insulin administrative Service Officer!).

In a hurry? No time for my Gibberish? Start reading the last paragraph to get a quick answer.

The first time I made the injection, the experience was magical, and morale boosting…Thanks be to the lord, I haven’t messed up anything yet(other than that one time the needle bent ‘by itself’ while I was drawing Insulin!). Jokes apart. An important thing I noticed while injecting him, there was no BLOOD!!!

If you belong to that one percent who already know the answer, just ignore us simpletons, and sure check out our other articles, that I’m pretty sure will amuse you.

After some quick googling, we found the reason,

  • An injection is a medical procedure, in which an individual is injected by himself or others with medication or other drugs(in case of substance abuse) through a syringe (or other similar equip with a needle) by piercing the skin. This is a rough definition I came up with, if you have a better one let me know in the comments…
  • Injections can be divided into different types in different ways, like medical injections , abuse injections,

Based on the depth upto which the needle enters the body, we get the following types,

  1. Intradermal Injections – The injection needle is really tiny that it barely crosses the skin,
  2. Intramuscular Injections – The name says it all, these Injections are made directly into the muscles. Meds injected this way are absorbed faster due to the high blood supply to the muscles,
  3. Subcutaneous Injections – Here the needle pierces the first two layers of the skin Epidermis, Dermis, and the medication is released into the underlying fatty layer called the subcutaneous tissue layer.

Also there is another called the intravenal, wherein the injection is directly done into the blood supply by puncturing a blood vein (Oh..poor vein…).

Leonardo Dicaprio holding a glass of wine saying your answer.
…Insulin is a subcutaneous injection…

Now back to the question, why insulin injections don’t draw blood? Insulin injections are subcutaneous in nature and not intravenal, We are not injecting into a vein. We merely deposit the preparation into a fat layer under the skin, and let the body absorb the medication from there. But that doesn’t protect the blood vessels there from puncture does it? Yes, in the process of injecting we do damage the blood vessels running there. But again why no blood? Since the blood vessels there are too tiny and the blood they carry is very low and the number of vessels we damage too is less, the blood that gets leaked by the damage won’t even make it to the surface. In parallel our body’s clotting factor quickly seals the wound. And VOILA!!! That’s why there’s no blood shed.

There maybe some exceptions, but this is the reason why there mostly is no blood leakage during insulin and other such injections.

Thanks for reading folks!!!
