What Does Type 2 Diabetes Mellitus Mean


Gregor Mendel: Father Of Genetics

What is Diabetes Mellitus?

The idea of particulate inheritance of genes can be attributed to the monk who published his work on pea plants in 1865. However, his work was not widely known and was rediscovered in 1901. It was initially assumed that only accounted for large differences, such as those seen by Mendel in his pea plants; and the idea of additive effect of genes was not realised until ‘s paper, “” Mendel’s overall contribution gave scientists a useful overview that traits were inheritable. His pea plant demonstration became the foundation of the study of Mendelian Traits. These traits can be traced on a single locus.

Can Type 2 Diabetes Turn Into Type 1

If you have type 2 diabetes, you might be wondering if it will ever turn into type 1 diabetes. Its understandable that you would think about this, especially if you take insulin. In short, however, the answer is no.

Type 1 and type 2 diabetes, two of the most common forms of diabetes, are actually two very different conditions. Type 1 diabetes is an autoimmune disease, which means that the body attacks the cells in the pancreas that make insulin. As a result, someone with type 1 needs to inject insulin in order to survive. Researchers believe that genetics or environmental factors are the cause of type 1. For the most part, type 1 diabetes is more common in children, adolescents and young adults but anyone at any age can develop type 1 diabetes.

So, type 2 diabetes does not become type 1 diabetes. But it is possible for someones type of diabetes to be misdiagnosed. In other words, someone may be told they have type 2 diabetes, but they actually have type 1 diabetes. Heres why: diabetes symptoms can be the same in both type 1 and type 2 diabetes. For example, if your blood sugar is high, you may feel tired and thirsty and you might lose some weight. If you go to the doctor because of your symptoms, you may be quickly diagnosed with type 2 and prescribed a diabetes pill to take. This is more likely to happen if youre an adult and if youre overweight or obese .

What Is The Meaning Of Type 2 Diabetes Mellitus

What is the meaning of type 2 diabetes mellitus? Type 2 diabetes is a chronic disease. It is characterized by high levels of sugar in the blood. Type 2 diabetes is also called type 2 diabetes mellitus and adult-onset diabetes. Thats because it used to start almost always in middle- and late-adulthood.

What causes type 2 diabetes mellitus?;Type 2 diabetes is primarily the result of two interrelated problems: Cells in muscle, fat and the liver become resistant to insulin. Because these cells dont interact in a normal way with insulin, they dont take in enough sugar. The pancreas is unable to produce enough insulin to manage blood sugar levels.

What is the difference between Type 1 and Type 2 diabetes mellitus?;The main difference between the two types of diabetes is that type 1 diabetes is a genetic disorder that often shows up early in life, and type 2 is largely diet-related and develops over time. If you have type 1 diabetes, your immune system is attacking and destroying the insulin-producing cells in your pancreas.


What does mellitus mean in diabetes?;Diabetes mellitus is a condition that occurs when the body cant use glucose normally. Glucose is the main source of energy for the bodys cells.

During a test, blood is taken from a vein and sent to a pathology lab. The tests that can be done include:


  • a fasting sugar test fasting is required for at least 8 hours, which may mean not eating or drinking overnight
  • a random glucose test taken at any time during the day
  • an oral glucose tolerance test a patient who has fasted drinks a sugary drink and then has a blood test done 1 and then 2 hours later

Causes Of Type 1 Diabetes

The bodys immune system is responsible for fighting off foreign invaders, such as harmful viruses and bacteria.

In people with type 1 diabetes, the immune system mistakes the bodys own healthy cells for foreign invaders. The immune system attacks and destroys the insulin-producing beta cells in the pancreas. After these beta cells are destroyed, the body is unable to produce insulin.


Researchers dont know why the immune system sometimes attacks the bodys own cells. It may have something to do with genetic and environmental factors, such as exposure to viruses. Research into autoimmune diseases is ongoing.

Receiving A Type 2 Diabetes Diagnosis

Whether or not you have prediabetes, you should see your doctor right away if you have the symptoms of diabetes. Your doctor can get a lot of information from blood work. Diagnostic testing may include the following:

  • Hemoglobin A1C test.This test measures average blood glucose levels for the previous two or three months. You dont need to fast for this test, and your doctor can diagnose you based on the results. Its also called a glycosylated hemoglobin test.
  • Fasting plasma glucose test. This test measures how much glucose is in your plasma. You may need to fast for eight hours before having it.
  • Oral glucose tolerance test. During this test, your blood is drawn three times: before, one hour after, and two hours after you drink a dose of glucose. The test results show how well your body deals with glucose before and after the drink.

If you have diabetes, your doctor will provide you with information about how to manage the disease, including:

  • how to monitor blood glucose levels on your own
  • dietary recommendations
  • physical activity recommendations
  • information about any medications that you need

You may need to see an endocrinologist who specializes in the treatment of diabetes. Youll probably need to visit your doctor more often at first to make sure your treatment plan is working.

If you dont already have an endocrinologist, the Healthline FindCare tool can help you find a physician in your area.

What Types Of Diabetes Require Insulin

What is Diabetes Mellitus?

People with Type 1 diabetes need insulin to live. If you have Type 1 diabetes, your body has attacked your pancreas, destroying the cells that make insulin. If you have Type 2 diabetes, your pancreas makes insulin, but it doesnt work as it should. In some people with Type 2 diabetes, insulin may be needed to help glucose move from your bloodstream to your bodys cells where its needed for energy. You may or may not need insulin if you have gestational diabetes. If you are pregnant or have Type 2 diabetes, your healthcare provider will check your blood glucose level, assess other risk factors and determine a treatment approach which may include a combination of lifestyle changes, oral medications and insulin. Each person is unique and so is your treatment plan.

Yes, its possible for diabetes to cause hair loss. Uncontrolled diabetes can lead to persistently high blood glucose levels. This, in turn, leads to blood vessel damage and restricted flow, and oxygen and nutrients cant get to the cells that need it including hair follicles. Stress can cause hormone level changes that affect hair growth. If you have Type 1 diabetes, your immune system attacks itself and can also cause a hair loss condition called alopecia areata.
