What is Insulin?

Insulin is a hormone produced by the pancreas that controls blood sugar (glucose) levels in the body. It allows glucose to enter cells, allowing them to function.

People with diabetes, whether type 1 or type 2, do not produce enough insulin or cannot use it properly, leading to high blood sugar levels (hyperglycemia).

Manufactured insulin comes in many forms – injections, pens, pumps, and inhalable – to manage blood sugar levels and prevent diabetes complications. Insulin lowers blood sugar by moving glucose from the bloodstream into the cells, keeping energy levels balanced and overall health.

Insulin management is critical to controlling diabetes, keeping blood sugar within range, and avoiding long-term complications.

What are the Different Types of Insulin for Diabetes Management?

Different types of insulin help manage diabetes. Each works at different durations to help control blood sugar levels.

Rapid-acting insulin

Rapid-acting insulin works quickly, typically starting within 5 to 20 minutes after injection.

This type of insulin is particularly effective in managing blood sugar spikes after meals. It reaches its peak effectiveness around 1 to 2 hours after administration and lasts about 3 to 5 hours.

Typical forms of rapid-acting insulin include insulin glulisine (brand name Apidra), insulin aspart (brand name NovoLog), and insulin lispro (brand name Humalog). Inhaled insulin is also considered a rapid-acting option.

Rapid-acting insulin analogs are usually taken just before meals to help keep blood glucose levels within a healthy range.

This insulin analog reduces the chances of post-meal spikes in blood sugar, making it an essential tool for individuals who need quick insulin coverage during or after eating.

Regular (short-acting) insulin

Regular insulin, or short-acting insulin, starts lowering blood sugar levels about 30 to 45 minutes after injection. It reaches its peak effectiveness around 2 to 4 hours and continues to work for 5 to 8 hours.

Doctors frequently recommend short-acting insulin analogs for those who need precise control of their blood sugar levels during the day, especially to manage post-meal spikes.

People commonly use regular insulin with other types of insulin for more balanced diabetes management.

Examples of regular insulin products include Novolin R and Humulin R. These insulins are designed to help prevent large spikes in blood sugar, offering both short-term control and steady coverage between meals.

Intermediate-acting insulin

Intermediate-acting insulin works more slowly than rapid-acting and regular insulin. It takes effect about 2 hours after injection and peaks between 4 to 12 hours later. This type of insulin provides steady blood sugar control throughout the day and night.

NPH insulin (also known as isophane) is the most well-known intermediate-acting insulin.

It lasts 14 to 24 hours, making it an excellent choice for managing blood sugar levels between meals or overnight. This insulin helps keep blood sugar from rising too much during periods when you are not eating.

Common brands of NPH insulin include Humulin N, Novolin N, and Novolin NPH. These insulins are often taken twice a day and can be combined with faster-acting insulins to provide more complete blood sugar control.

Long-lasting insulin

Long-lasting insulin, such as glargine, maintains steady insulin levels daily.

It begins acting within 1 hour of injection and provides a consistent effect without any peak. This type of insulin lasts up to 24 hours, offering reliable blood sugar control throughout the day.

Insulin glargine (Lantus) is one of the most commonly prescribed long-lasting insulins. It is ideal for individuals needing continuous insulin support to manage their blood glucose levels effectively.

Another widely used long-lasting insulin is Levemir (insulin detemir). Both insulins help keep blood sugar levels stable without fluctuations.

Ultra-long-acting insulin

Ultra-long-acting insulin provides even more extended blood sugar control than long-lasting insulin. It reaches your bloodstream in about six hours and has a steady effect without a peak.

This insulin can last up to 36 hours or more, making it an excellent option for patients who need continuous insulin coverage over a long period.

Insulin degludec, available under Tresiba, is the primary example of ultra-long-acting insulin. It offers a flexible dosing schedule and helps manage blood sugar levels consistently throughout the day and night.

Premixed insulin

Premixed insulin combines two types of insulin, rapid-acting and intermediate-acting, into one vial or pen.

This combination provides the advantage of quick-acting insulin to control blood sugar spikes after meals and longer-lasting insulin for continuous blood sugar management throughout the day. Typically, premixed insulin starts working within 5 to 60 minutes and can last up to 16 hours.

Premixed insulin simplifies diabetes management by reducing the need for multiple injections. It is ideal for individuals needing an easier, more convenient insulin regimen.

Premixed insulin offers flexibility in managing blood glucose levels. It is available in various ratios, such as 25/75, 30/70, 40/60, and 50/50. Faster-acting insulin is usually present in smaller amounts than longer-acting insulin.

Following the prescribed regimen, patients inject the premixed insulin two or three times a day before meals.

Ways to Use Insulin

There are several ways to use insulin: shots, pens, pumps, or inhalation.

Your method depends on your doctor’s advice and your health condition.

Insulin Shots or Pens

Insulin shots are one of the most common ways to administer insulin.

For a more convenient injection, inject insulin directly into the fatty tissue under the skin using a syringe, needle, or pen-like device.

The number of injections you need per day depends on the type of diabetes you have and how your body responds to insulin. In some cases, you may need to inject insulin multiple times a day to maintain stable blood sugar levels. Insulin pens are easy to use and allow for precise dosing.

Insulin Pump

An insulin pump provides a continuous supply throughout the day, helping to mimic the body’s natural insulin release.

The pump is worn outside the body and delivers insulin through a thin tube under the skin. It offers a steady flow of rapid-acting insulin, and you can also give yourself extra doses during meals for better blood sugar control.

The pump can make insulin delivery more convenient and flexible, reducing the need for multiple injections. Various types of insulin pumps are available, and your healthcare provider will help you choose the right one for your lifestyle.

Inhaled Insulin (Afrezza)

Those who prefer not to inject insulin can choose fast-acting inhaled insulin, used in an inhaler at the start of each meal.

This insulin delivery method is effective for managing blood sugar spikes after eating.

However, inhaled insulin is not suitable for everyone, especially people who smoke or have lung conditions such as asthma or chronic obstructive pulmonary disease (COPD).

It is important to consult your doctor first to determine if this method fits you well.

Frequently Asked Questions

Insulin is a hormone that helps regulate blood sugar levels in your body. It allows cells to absorb glucose for energy and helps store excess glucose in the liver. People with diabetes may need to take insulin because their bodies either do not produce enough or cannot use it effectively.

Insulin is needed for people with type 1 diabetes because their bodies do not produce insulin. In type 2 diabetes, your doctor may require insulin if lifestyle changes and other treatments cannot effectively control blood sugar levels.

Insulin can cause mild side effects like redness, swelling, or itching at the injection site. Rarely, more severe allergic reactions may occur, including nausea and vomiting. A common side effect is hypoglycemia (low blood sugar), which can happen if insulin is not balanced with food, exercise, or calorie intake. Symptoms of low blood sugar include fatigue, sweating, confusion, and even seizures. If you experience any side effects, contact your doctor for guidance.

You can inject insulin into the abdomen (belly), the back of the upper arms, the upper buttocks, and the outer thighs.

Not everyone with type 2 diabetes needs insulin. Some people can manage their blood sugar with a healthy diet and exercise. However, others may require insulin or medications if lifestyle changes are insufficient.

Diabetic patients can endure 12 to 24 hours without insulin after their last injection, depending on the duration of the insulin. They may develop diabetic ketoacidosis (DKA) within 24 to 48 hours. DKA is a severe condition in which the body does not have enough insulin, so it starts breaking down fat for energy.

Insulin administration timing depends on the type of insulin and your treatment plan.

  • A rapid-acting insulin is injected before meals to manage blood sugar spikes after eating.
  • Short-acting insulin is usually given about 30 minutes before a meal.
  • Intermediate-acting insulin is typically administered twice daily, in the morning and evening, to cover the time between meals.
  • People generally administer long-acting insulin once daily to maintain steady insulin levels over 24 hours.

When choosing how to inject insulin, consider your lifestyle and follow your doctor’s advice. Your doctor will guide you to the best choice based on your needs and preferences.

The best way to store insulin is to keep unopened insulin in the fridge. Store the insulin you currently use at room temperature in a cool, safe place away from direct heat and sunlight. Insulin kept at room temperature lasts about a month. Avoid freezing insulin, and always check the expiration date before use.
