Insulin is a hormone that is produced by the pancreas and is required for maintaining sugar levels in the body,  people with type 1 diabetes the pancreas does not produce insulin. And in type 2 diabetes insulin does not work as it  nornally should . The amount of insulin produced by the pancreas may also be less.

How is Insulin obtained ?

Earlier, insulin was sourced from slaughter houses. That is from the pancreas of dead animals. Now, Insulin can be synthesised in the laboratories by sophisticated technologies ( recombinant DNA) .

Who needs Insulin?

In type 1 diabetes , Insulin is a must for living.  In type 2 diabetes, doctors advice Insulin in certain situations like pregnancy, during and after surgery, severe infection and when patients are not able to eat. When tablets do not work, one needs insulin for diabetic control.

Is Insulin the best option for people with type 2 diabetes  ?

There are several advantages of insulin. Recent research indicates that use of insulin from the beginning or at least for some time at the beginning, it not only helps in controlling diabetes better, but also maintains  pancreatic function in the long run.

How many times a day do one need to take insulin ?

This depends on the insulin regimen your doctor advises. There are several regimens doctors use. The best regimen is to use three short acting insulin before main meals and a longer acting insulin at bed time to take you through the night. The problem of this regimen is that you need to take four  injections a day. Now, we have insulin available in  a mixed form which can be injected two times a day. , before breakfast and before dinner. If one is on a combination of insulin and tablets , one can manage with one injection a day. In that case the best time to take insulin is before dinner, not before breakfast. Longer acting insulin is available which works for 24 hours.

What is the best time to take Insulin?

The best time to take ordinary insulin is 30 minutes before food, so the level of insulin and sugar in the blood after food intake matches . But in case you have eaten already, it is better to take the injection immediately after, rather than not taking.

A new but costly insulin is available ( Aspart,Lispro ), which can be injected immediately before food, i.e if you do not need a time span as it works faster than ordinary insulin.

Should I go to a doctor or a nurse to inject insulin?

You can inject it yourself. There is always a fear initially , but everybody manages well once they learn.

Insulin injection is less painful when you inject yourself rather than a doctor or a nurse doing it.

Are there any side effects of Insulin?
Insulin is a natural hormone, so side effects are not expected. Sometimes there will be some skin allergy with animal insulin, but this is rare.
There is a chance of little gain in weight, mostly due to better control. ( You lose weight when sugar is uncontrolled and you gain your  lost weight back when your control improves).

Low sugar ( Hypo) can occur and that is mainly due to mismatch or miscalculation of diet and insulin.

Can I take insulin in some form other than Injection?

The world  is still waiting for the day when insulin can be given without an injection. It is encouraging that plenty of research is on the pipeline to find out if an insulin delivery system without injection will be available. But for now, it is only injections.

Which insulin is better, animal or human?

Two types of animal insulins are available, one is bovine and the other is porcine. They have slight structural difference with human insulin. So far as the efficacy is concerned , there is little difference. Allergy to human insulin is very rare,  but can happen with animal insulin. Animal insulin is cheaper in comparison to human insulin.

What happens if I miss an insulin injection?

Try as best as you can, not to forget your dose, because it alters your control very much which is in fact not very good. If you have an access to check sugar either in lab or by pricking your finger, please do, so that you know where you  actually stand and take appropriate step in consultation with your doctor.

Apart from the Insulin treatment for diabetes which is a chronic disease resisting cure, there are many new treatments which have gone a long way in diabetes management.  A few of them are given below.
  1. Byetta( Exenatide)
  2. Liraglutide
  3. Januvia(Sitagliptin) and Galvus(Vildagliptin)
  4. Buccal sprays(Oral Recosulin)
  5. Insulin pumps

Why do we need Insulin?

When you eat a meal, the carbohydrate (starch, sugar or glucose) is absorbed from your intestines. Sugar enters the blood stream and is delivered to your liver. Normally, the pancreas simultaneously secretes insulin which is also delivered to your liver.

Insulin acts like a key to the gas cap of a car. It opens the cap to most of the cells in your body and allows the glucose to enter, to be stored and to be used as energy. In your liver insulin allows the storage of glucose as glycogen. Insulin also enters the general blood stream and is delivered to the cells in your body where it allows entry of glucose into the cells in your muscle, skin, and fatty tissues. The presence of glucose into the cells is the fuel for their normal function. When glucose enters the cells, your blood glucose concentration decreases. Therefore, insulin makes your blood sugar lower. Insulin also prevents the release of fat from the fat cells and glucose from the liver cells. If you lack insulin, the absorbed carbohydrate from your meal is not stored in your liver, but rather enters your bloodstream producing an abnormally high blood sugar. The cells and organs in the rest of your body are also unable to allow entry of sugar.

WHAT HAPPENS WHEN I DO NOT TAKE ANY INSULIN OR DO NOT HAVE ENOUGH INSULIN?
Lack of insulin causes your blood sugar to rise or increase. When the blood sugar exceeds (is more than) 180 mg/dl you begin to urinate frequently and get thirsty. Since no sugar (fuel) is entering your cells, you begin to feel run down and tired. If this continues your body turns to fat for fuel. A large amount of ketone bodies can make you sick to your stomach and cause even more urination. Finally you can get so sick that you begin to breathe heavily and lose you r ability to talk and stay awake. At this point diabetic ketoacidosis (DKA) is present and can lead to death if untreated or treated long after its onset.

When did you last have a complete health check up done? If you are above the age of 25 years and have a family history of Diabetes, I recommend you get one done immediately. Remember precaution is always better than cure.
