Insulin is a common issue in the medical field, and many seek to search for information related to it. In this article from  health beauty website , we will learn about the hormone insulin, its types, damages, its source, and how insulin works, in addition to identifying the symptoms of excess insulin.


Definition of Insulin:

What is insulin? Before talking about the types of insulin hormone, its harm, its source, how the insulin hormone works and the symptoms of its excess, let us first get to know the definition of insulin:

  • Insulin is a hormone that helps the body to use glucose (the energy into which the food a person eats) in order to obtain energy.
  • The beta cells in the pancreas are responsible for producing insulin.
  • Insulin introduces the sugar that is in the blood into the cells.
  • Glucose is secreted into the blood and then the cells of the body take it up and burn it; In order to give it the energy required to perform its vital processes, the cells need the hormone insulin to do the above.


Types of insulin

After we know what is insulin? Before talking about its source and how the hormone insulin works, let’s get acquainted with the types of insulin:

Short-acting or fast-acting insulin:

  • It starts working from ten minutes to half an hour.
  • It takes about four to five hours to work.
  • Prevents high blood sugar after meals.

Long-acting insulin:

  • It begins to work in the body between an hour and an hour and a half.
  • Part of this type expires after 18 hours, and another part expires after 24 hours.
  • Maintains the normal level of sugar in the blood.


Insulin side effects:

After we know what is insulin? And before talking about its source, how insulin works, and the symptoms of excess insulin in the body, let’s get acquainted with some of the damages of insulin:

Nausea and excessive sweating:

  • In the first period of its use, side effects begin to appear, the most famous of which is a decrease in the level of sugar in the blood.
  • This results in confusion, nausea, and excessive sweating.

blurry vision

  • In some cases, it may lead to a diabetic coma, and blurry vision may also occur.
  • As a result of the osmotic imbalance between the lens and the eye fluids.

skin Sensitivity:

  • At the beginning of the treatment with insulin, it is possible that the skin sensitivity will occur and appear in the form of redness and swelling.
  • However, it goes away after a short time when the body gets used to the insulin.

lip atrophy:

  • After a period of treatment, insulin may cause lipodystrophy if it is injected into the same place.
  • That’s why doctors always recommend injecting insulin into different parts of the body.

Vomiting and nausea:

  • The period of beginning treatment is difficult for people with diabetes .
  • Because insulin causes constant vomiting and nausea.


  • Insulin has side effects on the blood, including an increase in plasma viscosity, a decrease in its number, and an increase in blood platelets.
  • In some cases, it leads to anemia if it is used in large doses.

Kidney problems:

  • When taking a large dose of it, it reduces the level of sugar in the blood.
  • This may lead to some problems in the kidneys.

low weight:

  • Sometimes it may cause some metabolic problems.
  • Which affects the growth of the body and causes a significant decrease in weight.


Insulin source:

After talking about what is insulin? And its types and harms, let us now learn about the source of insulin:

  • Insulin, usually given by injection, is extracted from the pig’s pancreas.
  • Due to the quality of the insulin secreted by the pig’s pancreas and being close in structure to the insulin secreted in the human pancreas.


What are the symptoms of increased insulin?

After talking about what is insulin? And from its source, we will learn about the symptoms of excess insulin: There are many symptoms that appear when insulin is high in the body, such as:

  • Weight gain and a craving for sugar.
  • Constant feeling of hunger.
  • As well as feeling tired, exhausted and anxious.
  • In addition to suffering from a lack of focus.


How does the hormone insulin work?

After talking about what is insulin? Let’s get acquainted with the mechanism of action of insulin:

  • After a meal, the digestive system breaks down the food.
  • The carbohydrates in this food are broken down into simple sugar.
  • When sugar is absorbed from the digestive system into the blood, the blood sugar level rises, and your circulatory system transports glucose to muscle cells.
  • This is where energy is generated and the introduction of glucose into muscle cells requires insulin.
  • Whenever the glucose in the blood rises, the pancreas becomes sensitive and then stimulates the manufacture of insulin and its secretion in the blood.
  • Secreted insulin plays a role in the blood sugar balance process.
  • Insulin binds to the cellular membrane proteins of liver cells, muscle cells, and fat cells.
  • This binding stimulates the cell membrane and causes it to bind to phosphorous, on the inner scale a phosphorylation process occurs.
  • A series of chemical reactions occur with specific proteins in the cell.
  • As a result of these interactions, the glucose entry protein moves toward the cell surface.
  • When this vesicle fuses with the cell membrane, the glucose gates on the cell membrane increase, and thus the level of glucose in the blood decreases.
  • Now the sugar is inside the cell and is used for metabolic processes that convert ATP, the energy compound, to all the cells of the body.

Insulin resistance disease:

Insulin resistance can occur as a result of multiple causes, and there are a number of tests that explain how to measure insulin and what measure is dangerous to human life:

Causes of insulin resistance disease:

After we know what insulin is, let’s know the causes of insulin resistance in the body:

  • Excess weight can cause the accumulation of fats and carbohydrates, which puts pressure on the pancreas and leads to insulin resistance.
  • Fatty liver disease caused by excessive alcohol consumption.
  • Polycystic ovary syndrome in women.
  • Insulin resistance can also decrease with age and begin to appear after 47 years.
  • Insulin resistance can also be caused by genetic factors.
  • Some diseases Cushing’s syndrome.
  • Sleep apnea diseases.
  • The use of some medications in psychological treatments and psychosis.
  • Chemical drugs used in the treatment of AIDS, so you can learn about the herbal treatment of AIDS .
  • Hepatitis C virus , the most common of which is the hepatitis B virus .


Symptoms of insulin resistance:

After we know what insulin is and the most important causes of insulin resistance, let us know the important symptoms that indicate insulin resistance, which are:

  • Acanthosis nigricans, which is dark spots on the skin.
  • When measured, the pressure is about 130/80.
  • Triglyceride levels rise during fasting, exceeding 100 ml/dL in men and 150 in women.
  • HDL cholesterol levels drop below 50 ml/dL in women and 40 in men.
  • Waist circumference increased significantly, exceeding 35 inches in women and 40 inches in men.


How can insulin resistance be checked?

After we know what insulin is in today’s article and how insulin resistance occurs in the body, let’s learn together how to test the insulin resistance test:

Hemoglobin A1c test:

  • The blood sugar level in the past three months is obtained in this test.
  • Diabetes can be detected early with this test.

Fasting plasma glucose test:

  • Blood sugar is measured after fasting for at least 10 hours.
  • This test clearly shows the level of sugar in the blood.
  • The oral glucose tolerance test is also checked immediately after the fasting test by consuming a sugary drink and measuring the sugar level afterwards.


At the end of an article what is insulin?

In an article, we learned what insulin is to insulin, how it can be obtained, when it is used, and what are the most important symptoms of increased insulin in the blood, in addition to learning about insulin resistance and various insulin tests.
