Difference Between Type 1 And Type 2 Diabetes (With Table)

Diabetes is of two subtypes. The most prevalent type is Type I. Type I diabetes is most commonly diagnosed in children and teenagers and type 2 is found after a long wait of diagnosis in adulthood. But both types of diabetes are worse. 

For centuries people believed that sugar is the main cause of diabetes and should be avoided at any cost but as people researched and concluded that there are various causes for diabetes and people have to avoid more than sugar.

Type 1 vs Type 2 Diabetes

The difference between type 1 and type 2 diabetes is that type 1 diabetes require a person to be on insulin for the remainder of his life because his body stops making insulin whereas in type 2 diabetes your pancreas generates a lot of insulin but insulin is not recognized by the cells which are used to convert glucose to energy.

Type 1 diabetes is also termed autoimmune diabetes. The triggers for the beginning of this autoimmune condition are still unknown. The most likely cause is genetic characteristics from the patient, which are modified by environmental factors as well. Type I diabetes necessitates the use of insulin for the rest of one’s life. This does not rule out the possibility of them enjoying a long and prosperous life.

Diabetes type 2 is usually discovered later in life. Older folks and obese people are more likely to have this illness. In a few countries like the United States, type 2 diabetes cases have mirrored obesity cases, and most doctors believe there is a clear link between obesity and the development of this disease.

Comparison Table Between Type 1 And Type 2 Diabetes

Parameters of ComparisonType 1 DiabetesType 2 Diabetes
Meaning These types of diabetes are also known as autoimmune conditions that means our body stops producing insulin and attacking our cells.These types of diabetes affect our body by not making enough insulin in or the existing insulin doesn’t work properly. This is also called insulin resistance.
Causes No regulation of blood glucose as the body does not make enough insulin and attack pancreatic beta cells.The body stops producing enough insulin this results in a stoppage of glucose entering the cells.
Appearance of SymptomsAppear more quicklyAppear more slowly
Risk Factors Having a family history of diabetes, being born with genetic factors, infections such as mumps or rubella are some risk factors.Having a family history of diabetes, obesity, smoking, lack of exercise, unhealthy diet, etc are some risk factors. 
Treatment and Prevention Treatments include insulin pumps and other drugs such as pramlintide.Metformin, SGLT2, helps in reducing sugar levels.

What is Type 1 Diabetes?

Type 1 diabetes is a disorder in which the blood sugar or glucose levels are abnormally high. 

Type 1 diabetes happens when the body does not produce insulin at all. 

As a result, persons with type 1 diabetes require more insulin from a source other than their bodies.

The insulin hormone generated by the pancreas regulates blood sugar levels in most people. 

The insulin hormone produced by the pancreas can be disturbed when illness strikes it. 

Insulin binds glucose in the blood and transports it to the cells to be turned into energy when food enters the body and is digested and enters the bloodstream.

The body of diabetes, on the other hand, is unable to convert glucose into energy. Because there is no insulin to transport glucose into the cells. That increases the level of glucose. 

The most frequent kind of diabetes in children is type 1.

Few symptoms or signs of type 1 diabetes:

  • Excessive thirst
  • Hunger has increased (especially after eating)
  • Mouth is parched
  • Vomiting and an upset stomach
  • Urination regularly
  • Weight loss that is unexplained even though you are eating and feeling hungry
  • Fatigue
  • Vision is blurry

What is Type 2 Diabetes?

T2DM (Type 2 Diabetes Mellitus) is a metabolic illness defined by an increase in blood sugar levels caused by a disruption in insulin synthesis and/or insulin activity in the human body.

In a body when blood sugar levels are high, the kidneys have to work extra hard to eliminate excess sugar that isn’t absorbed by the body through urine. People with type 2 diabetes will become thirsty and urinate frequently due to excessive renal work.

The symptoms and signs of type 2 diabetes are the same as type 1 diabetes.

People in their forties and fifties are more likely to develop type 2 diabetes.

However, lifestyle changes have been linked to the beginning of disease as early as adolescence. 

Although there is no specific age at which a person might develop type 2 diabetes, the likelihood of developing the condition increases as one gets older. Men are more probable than women to be diagnosed with type 2 diabetes.

Main Differences Between Type 1 And Type 2 Diabetes

  1. Type 1 diabetes is unavoidable. Type 2 diabetes, on the other hand, can be avoided by following basic healthy lifestyle behaviors such as eating sensibly and exercising daily.
  1. Low blood sugar levels, often known as hypoglycemia, are common in people with type 1 diabetes. In type 2 diabetics unless the person has and is taking diabetes medication, no low blood sugar levels are detected.
  1. Type 1 diabetes is usually found when a person is in childhood or early adolescence. Type 2 diabetics are usually discovered in adulthood.
  1. Our bodies stop producing insulin in type 1 diabetes, while they continue to produce insufficient insulin in type 2 diabetes.
  1. Only 10% of type 1 diabetes patients account for all diabetes cases worldwide, while 90% of type 2 diabetes patients account for all diabetes cases worldwide.


Type 1 diabetes is a genetic disease and gets discovered early in life but type 2 diabetes doesn’t get early detection and develops over time.

As with Type I and Type 2 diabetes, problems do occur. Heart disease, nerve damage, kidney illness, and skin problems can all be avoided if individuals listen to their doctors, educate themselves about their diseases, and take proactive steps to cure them. Diabetic complications are rare and they cannot be cured but can be prevented.
