What is an insulin injection and how does it work?

An insulin injection is a shot of insulin that you give yourself in order to bring your blood sugar levels back down to normal after they’ve become elevated. This happens most often when you eat food that causes your blood sugar levels to spike, or if you’re having issues with your pancreas and can’t make enough insulin naturally.

Insulin injections are fast-acting, making them effective at bringing down your blood sugar levels quickly, but the effect does not last very long, which means you may need to have additional injections throughout the day in order to maintain the proper levels of glucose in your bloodstream.

How insulin works

All carbohydrates, sugars, and starches are converted into glucose when digested. This leads to a spike in blood sugar levels as well as a release of hormones from our pancreas. Insulin helps move glucose from our bloodstream into our cells. Type 1 diabetes occurs when there’s not enough insulin in your body (insulin deficiency), causing blood sugar levels to become dangerously high.

Types of Insulin

There are four main types of insulin: Rapid Acting (insulin taken before a meal), Short Acting (insulin taken with meals), Intermediate Acting, and Long Acting. When people refer to insulin they’re almost always talking about human insulin or synthetic human insulin analogs like Lantus, Levemir, or Tresiba.

How Long Do Insulin Injections Last?

The effect of insulin injections lasts for about 2 hours, meaning you’ll need to repeat your injections every 2 hours if you wish to sustain proper blood sugar levels. If you have Type 1 diabetes, do not take longer than 8-10 hours without taking another dose.

If you are on oral medications, consult with your physician before adjusting your schedule accordingly. For example, if your next dose is in 4 hours but you haven’t eaten yet – take an extra dose now to cover until food intake.

Why Are Insulin Injections Used?

Insulin injections are used for a variety of medical conditions to control or decrease blood sugar levels. Low blood sugar (also known as hypoglycemia) occurs when your blood glucose, or blood sugar, falls below normal levels.

It’s caused by an imbalance between how much you eat, drink and exercise versus your body’s ability to break down sugars from these foods into energy.

Where Do I Get Insulin Injections From?

Insulin injections can be given either subcutaneously or intramuscularly. The difference between these types of injections relates to where you receive them in your body. Subcutaneous injections are just below your skin, while intramuscular shots are directly into a muscle.

Both types are effective, but one might be better suited for your particular needs than another. Your doctor will determine which type of insulin injection you should use during your treatment regimen based on factors like overall health and diabetes severity.

Why do people choose to take insulin injections rather than oral medications?

Insulin injections are often a last resort for diabetics who have trouble keeping their blood sugar levels under control, because they tend to be more effective than oral medications.

However, there are some disadvantages to injecting insulin as well. Some people find that taking insulin injections less convenient than taking pills, particularly if they are already having problems swallowing pills.

How effective are insulin injections in helping with my condition

Insulin injections can be used by a diabetic person to keep their blood sugar in check, however many diabetics choose not to use them. Insulin injections are a more reliable way of keeping your blood sugar at a safe level but they have some unpleasant side effects which may outweigh their benefits.

Despite being effective most people decide to avoid using them because of how difficult they are to self-administer, and instead opt for medication or an insulin pump.
