Insulin and How It Works

Before jumping into insulin and how it works, kindly read full article on Insulin. well, It is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).

Insulin then attaches to and signals cells to absorb sugar from the bloodstream. Insulin is often described as a “key,” which unlocks the cell to allow sugar to enter the cell and be used for energy. kindly read more about Diabetes.

The importance of insulin

Insulin is a hormone made in your pancreas, a gland located behind your stomach. It allows your body to use glucose for energy. Glucose is a type of sugar found in many carbohydrates.

After a meal or snack, the digestive tract breaks down carbohydrates and changes them into glucose. Glucose is then absorbed into your bloodstream through the lining in your small intestine. Once glucose is in your bloodstream, insulin causes cells throughout your body to absorb the sugar and use it for energy.

Insulin also helps balance your blood glucose levels. When there’s too much glucose in your bloodstream, insulin signals your body to store the excess in your liver. The stored glucose isn’t released until your blood glucose levels decrease, such as between meals or when your body is stressed or needs an extra boost of energy.

Insulin as treatment for diabetes

To learn more on insulin and How It Works your actually need read about Injections of insulin can help treat both types of diabetes. The injected insulin acts as a replacement for or supplement to your body’s insulin. People with type 1 diabetes can’t make insulin, so they must inject insulin to control their blood glucose levels.

Many people with type 2 diabetes can manage their blood glucose levels with lifestyle changes and oral medication. However, if these treatments don’t help to control glucose levels, people with the condition may also need insulin to help control their blood glucose levels.

Types of insulin treatments

All types of insulin produce the same effect. They mimic the natural increases and decreases of insulin levels in the body during the day. The makeup of different types of insulin affects how fast and for how long they work.
  • Rapid-acting insulin: This type of insulin begins working approximately 15 minutes after injection. Its effects can last between three and four hours. It’s often used before a meal.
  • Short-acting insulin: You inject this insulin before a meal. It starts working 30 to 60 minutes after you inject it and lasts five to eight hours.
  • Intermediate-acting insulin: This type of insulin starts working in one to two hours after injection, and its effects may last 14 to 16 hours.
  • Long-acting insulin: This insulin may not start working until about two hours after you inject it. Its effects can last up to 24 hours or longer.

Administration and dosage

You can’t take insulin by mouth. You must inject it with a syringe, insulin pen, or insulin pump. The type of insulin injection you use will be based on your personal preference, health needs, and insurance coverage.

Your doctor or diabetes educator will show you how to give yourself the injections. You can inject the insulin under the skin in many different parts of your body, such as:

  • Thighs
  • Buttocks
  • Upper arms
  • Abdomen
Don’t inject insulin within two inches of your belly button because your body won’t absorb it as well. You should vary the location of injections to prevent the thickening of your skin from constant insulin exposure.

Insulin use varies by person according to their blood glucose levels and diabetes management goals. Your doctor may instruct you to give yourself insulin 60 minutes before a meal or just before eating. The amount of insulin you’ll need on a daily basis depends on factors such as your diet, level of physical activity, and severity of your diabetes.

Some people only need one insulin shot per day. Others need three or four. Your doctor may also have you use both rapid-acting insulin and long-acting insulin.

Insulin reactions

Hypoglycemia, or blood glucose levels that are too low, can sometimes happen when you take insulin. This is called an insulin reaction. If you exercise too much or don’t eat enough, your glucose level can drop too low and trigger an insulin reaction. You need to balance the insulin that you give yourself with food or calories. Symptoms of insulin reactions include:

  • tiredness
  • inability to speak
  • sweating
  • confusion
  • loss of consciousness
  • seizures
  • muscle twitching
  • pale skin

Treatment of Insulin and How It Works

To stop the effects of an insulin reaction, carry at least 15 grams of a fast-acting carbohydrate with you at all times. That’s about equal to any of the following:

  • 1/2 cup of non-diet soda
  • 1/2 cup of fruit juice
  • 5 Lifesaver candies
  • 2 tablespoons of raisins

Also, ask your doctor about a special pen called a glucagon pen. It can help resolve an insulin reaction.

Used appropriately, insulin helps keep your blood glucose level within a healthy range. Healthy blood glucose levels help reduce the risk of diabetes complications, such as blindness and the loss of limbs. It’s important to monitor your blood glucose level regularly if you have diabetes.

You should also make lifestyle changes to prevent your blood glucose level from getting too high. And talk to your doctor about ways to make your treatment with insulin as effective as possible.
