What is Diabetes?

Diabetes is a condition developed due to a rise in glucose or blood sugar. Glucose or blood sugar acts as the primary source of energy for the function of our cells, which comes from the food we eat. Insulin is a type of hormone that gets secreted by the pancreas of our body. 

This hormone will help the glucose in food to get into the cells and make them carry out their work. But once they don’t make enough or any insulin. As a result, glucose remains in the blood and stops reaching the cells. High glucose in the blood causes various types of health issues and primarily diabetes conditions.

What are Different Types of Diabetes?

There are many different types of diabetes, but the most seen ones are type 1 and type 2 diabetes. There is also one more diabetes that has become recently common is gestational diabetes.

What is Type 1 diabetes? 

One of the reasons that we are alive today is our powerful immune system that fights with all foreign invaders such as harmful bacteria and viruses.

People who are suffering from type 1 diabetes don’t make insulin. Their immune system suspects their body’s pancreas beta cells that get attacked and destroyed, as a result, it stops the production of insulin. So that people with type 1 diabetes can’t stay alive without a daily dose of insulin injection.

Most are seen in newborn babies and teenagers due to genes.

What is Type 2 Diabetes?

Type-2 diabetes is a disease or a condition due to which your body will not be able to use insulin fruitfully, also called insulin resistance in the body. 

If you develop type-2 diabetes, the pancreas in compensation produces more insulin. As your body is unable to use insulin effectively, your body accumulates more glucose in the bloodstream.

What is Insulin Injection?

As we already know, insulin is a hormone that reduces glucose in the body. Doctors use insulin to inject into diabetic patients to reduce the glucose in their bodies. These are called insulin injections.

What are the Types of Insulin Injection?

There are five types of insulin injections:

  • rapid-acting insulin
  • short-acting insulin
  • intermediate-acting insulin
  • mixed insulin
  • long-acting insulin

In brief,

Rapid-acting insulin, as its name indicates its starts working rapidly by somewhere between 3 to 20 minutes. This injection can last up to five hours. The best time to inject into the body is quickly after our meal, which is like our natural insulin. It will reduce the low glucose risk in the blood.

Short-acting insulin takes longer to start working than rapid-acting insulin. It has its maximum effect two to five hours after injection and lasts for six to eight hours. 

Intermediate-acting insulins begin to work about 60 to 90 minutes after injection, peak between 4 to 12 hours, and last for between 16 to 24 hours. 

Long-acting insulin, or basal insulin, is insulin that is advised to take in the morning due to its long and steady release of insulin that can last up to mid-day meals and overnight. It will last up to 12 hours and peak for 5-6 hours.

Mixed-insulin is a combination that contains very rapid-acting short-acting insulin along with intermediate-acting insulin.

Which type of diabetes requires insulin?

Type-1 diabetes:

Type-1 diabetes is also called insulin-dependent diabetes. People who are suffering from type-1 diabetes must take insulin injections four to five every day. Secretion of insulin hormone will become seized in patients who are suffering from type-1 diabetes.

Moving of glucose from the bloodstream to body cells will also become seized, and as a result, energy production will stop to carry out regular work.

Type-2 diabetes:

If you have type-2 diabetes or non-insulin-dependent diabetes, then the common question is whether to use insulin or not. Finding an answer to such questions is a little bit tricky as it depends on person to person. So, the answer will be yes and no.

The reason for such a mixed answer is because of situation dependency. People with type-2 diabetes do not always have to use insulin mandatorily.

People suffering from low blood sugar values need to make changes in their daily routine and diet. Even an increase in physical activity and some oral medication are also required to bring back the blood sugar levels to normal.

When to take Insulin for Type-2 Diabetes?

Patients suffering from type-2 diabetes blood sugar should become controlled with oral medication along with routine changes advised. If the patient’s blood sugar doesn’t come under control, it is preferred to use insulin to get blood sugar under control.

There are few reasons for type-2 diabetes to use insulin which may bring blood sugar under control. They are:

  1. It will bring down blood sugar levels rapidly down to the healthier range. If a type-2 diabetes patient is diagnosed with high blood sugar levels, then insulin will help in reducing blood sugar to healthy levels rather than focusing on the dietary changes that will take longer.
  2. It has fewer side effects than other medications.
  3. It will cost lesser than taking other medications.

A person with type-1 diabetes should necessarily take insulin. Nowadays, insulin is being recommended as initial therapy for the recovery of type-2 diabetes patients.

For people who are suffering from constantly above 250mg/dl fasting glucose, insulin is a better choice to keep patients’ blood sugar in control.

Insulin will appreciably help in bringing their blood sugar levels back to normal keep the patient healthy. For patients who observe regular fluctuations in their blood sugar levels, it is mandatory to take proper doctor’s consultation and guidance before deciding to do anything.

In which site does insulin need to be injected?

If you’re a who inject insulin regularly, you should keep changing injection sites constantly to ensure insulin is getting absorbed into the body.

For injecting insulin, ideal places would be in the sites where there will be a decent amount of fat layers and regular physical activity.

 The Common places for injecting insulin are the belly, upper arm, thighs, and buttocks. Even in the absorption belly part quickly absorbs insulin whereas, the buttocks slowly absorb.

It is mandatory to ‘rotate’ injection sites regularly to avoid stiffy skin or lumpy skin by injecting in that same area too long. Injecting in the same place will also decrease the absorption of insulin in that site.

Therefore, it is important to rotate injection sites regularly.

What is the Treatment for Diabetes Without Insulin Injection?

Currently, there is no other alternative to type-1 diabetes other than injections. Type-2 diabetes patients must take insulin therapy regularly along with healthy routine changes.

What are the Pros and Cons of Using Insulin Injection?

Pros of using insulin therapy are:

1.It will control elevated blood sugar rapidly when taken first thing in the morning.

2. Dose of insulin can be adjusted in precise to control the blood sugar.

3. They are very cheap comparing to other oral medications.

Cons of using insulin are:

  1.  It carries a high risk of causing low blood sugar if too much insulin is used.
  2. It will make you gain weight in some situations.


Insulins injections with the precise dosage are safe. Type-1 diabetes patients should necessarily take insulin regularly. Type-2 diabetes patients can either treat by following a healthy routine and some oral medication. Type-2 diabetes patients suffering from elevated blood sugar must use insulins to bring back blood sugar to control.
