Diabetes And Its Types

In 2020, according to the International Diabetes Federation (IDF), 463 million people have diabetes in the world and 88 million people in the Southeast Asia region. The most alarming fact is that out of 88 million people, 77 million belong to India. The prevalence of diabetes in the population is 8.9%, according to the IDF. This number is estimated to increase as years go by. Today in this blog i would like to throw some light on what is diabetes, its symtoms and its 3 major types.  

What is diabetes?

In very simple language, diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Let’s go a little into biology as it is critical to set the base before we move to it’s crux. Blood glucose is considered to be the main source of energy for you to function daily. From where does this come? It comes from the food you eat. Now what is insulin? Insulin is a hormone made by the pancreas which helps glucose from food get into your cells to be used as energy. Sometimes your body doesn’t make enough – or any – insulin or doesn’t use insulin well. Glucose then stays in your blood and doesn’t reach your cells. When this happens, you are either lablled type 1 or type 2 daibtes. If this situation continues for a long period of time, it can cause major health crital problems. Although diabetes has no cure, you can take steps to manage your diabetes and stay healthy.

Let’s look at the 3 major types of diabetes: Type 1, Type 2 and Gestational Diabetes in detail.

Type 1 Diabetes:

Type 1 diabetes (also known as T1D), previously known as juvenile diabetes, is a form of diabetes in which very little or no insulin is produced by the pancreas. As mentioned above, Insulin is a hormone needed for the body to convert blood sugar into energy. When you get diagnosed with Type 1 diabetes, you will experience high blood sugar levels in the body. 10% of the total diabetic population falls under the Type 1 diabetes category.

The classic symptoms of Type 1 diabetes:
1. Frequent urination.
2. Increased thirst.
3. Increased hunger.
4. Weight loss.

Additionally, you may also experience blurry vision, tiredness, and poor wound healing. Symptoms typically develop over a short period of time, often a matter of weeks.

The cause of Type 1 diabetes is unknown and hence there is no cure. But it is believed to involve a combination of genetic and environmental factors. If one of your family members are diabetic this is a risk factor. The biological mechanism when you get diagnosed with Type 1 diabetes involves an autoimmune destruction of the insulin-producing beta cells in the pancreas. Simply put, the good cells (Insulin producing beta cells) in your body are mistakenly attacked and killed.

How do I get tested?
Diabetes is diagnosed by testing the level of sugar or glycated hemoglobin (HbA1C) in the blood. Type 1 diabetes can be distinguished from type 2 by testing for the presence of autoantibodies.  Take A Glutamic Acid Decarboxylase Autoantibodies test (GAD antibodies test) to discover if your a Type 1 diabetic.

Treatment for maintaining blood glucose level:

  1. External insulin injections.

Type 2 Diabetes:

Type 2 diabetes (also known as T2D), formerly known as adult-onset diabetes, is a form of diabetes that is characterized by high blood sugar. This is generally due to insulin resistance, and a relative lack of insulin. Out of the total diabetic population, 90% falls under the type 2 category.

Symptoms are very similar to type 1 diabetes, they include:
1. Increased thirst.
2. Frequent urination.
3. Unexplained weight loss.

Symptoms may also include increased hunger, feeling tired, and scares that do not heal quickly. Often symptoms come on slowly. In the long run, if this high blood sugar condition prevails it can cause critical problems like heart disease, strokes, diabetic retinopathy which can result in blindness, kidney failure, and poor blood flow in the limbs which may lead to amputations.

Reason for Type 2 diabetes:
Type 2 diabetes primarily occurs as a result of obesity and lack of exercise. Some people are more genetically at risk than others.

Treatment for maintaining blood glucose level:

  1. Oral tablets.
  2. Controlled Diet.
  3. Regular Excercise.

Gestational Diabetes:

Gestational diabetes is a condition where you experience high blood sugar levels during pregnancy. Under gestational diabetes there are two classes:
Class 1:  Women with class A1 can manage it through diet and exercise.
Class 2: Those who have class A2 need to take insulin or other medications.

Does this problem stay for long?
No, Gestational diabetes goes away after you give birth.

But it can affect your baby’s health, and it raises your risk of getting type 2 diabetes later in life. A well-maintaing blood glucose level will help lower the risks of your baby being diabetic in the future.

Gestational Diabetes Symptoms:
Women with gestational diabetes don’t usually have symptoms or may chalk them up to pregnancy. Most find out that they have it during a routine screening while pregnant.
1. You’re thirstier than usual.2
2. You’re hungrier and eat more than usual.
3. You pee more than usual.

What causes gestational diabetes?
When you eat, your pancreas releases insulin, a hormone that helps move a sugar called glucose from your blood to your cells, which use it as energy.
During pregnancy, your placenta makes hormones that cause glucose to build up in your blood. Usually, your pancreas can send out enough insulin to handle it. But if your body can’t make enough insulin or stops using insulin as it should, your blood sugar levels rise, and you get gestational diabetes.

Gestational Diabetes Risk Factors:
You’re more likely to get gestational diabetes if you:
1. Were overweight before you got pregnant
2. Have blood sugar levels that are higher than they should be but not high enough to be diabetes (this is called prediabetes)
3. Have a family member with diabetes
4. Have had gestational diabetes before 1st baby.

Gestational Diabetes Tests and Diagnosis:
Gestational diabetes usually happens in the second half of your pregnancy. Your hemoglobin A1c (HBA1C) test will tell you your average level of blood sugar over the past 2 to 3 months. Infact, this text is taken to understand how well blood sugar levels are maintained once treatment has begun.

The above 3 types of diabetes have been so far the most prominent types. There are several ways you can lower blood glucose levels naturally. Utilize these ways to maintain blood sugar levels and stay healthy.
