Different types of diabetes | Discover the symptoms and complications of each type!

types of diabetes

According to global statistics, 1 out of every 5 people over the age of 65 suffers from diabetes, and this disease percentage is increasing over time.

Types of diabetes are controversial topics. In this article, we will summarize the agreed types of diabetes, their symptoms, and the causes of each type.

Knowing the symptoms and types of diabetes is very important for early diagnosis and prevention of the disease.


The different types of diabetes

Diabetes is defined as a group of diseases in which the body does not produce enough insulin, does not produce insulin properly, or does not use the insulin that is produced properly.

When any of the above happens, the body can’t get sugar into the cells, which leads to high blood sugar levels.

One of the main sources of energy in the human body is glucose (the sugar found in the blood). Insulin deficiency or insulin resistance leads to an accumulation of sugar in the blood, which leads to many health problems.

The main types of diabetes (there are other divisions, but this one is the most popular) are:

  • Diabetes Mellitus type 1 
  • Diabetes Mellitus type 2 
  • Pregnancy diabetes


Causes of diabetes for each type

The causes of diabetes vary among its types, each type has a specific cause that ultimately leads to this chronic disease.

Causes of type 1 Diabetes

Type 1 diabetes is an autoimmune condition in which your immune system mistakenly attacks the beta cells in your pancreas.

The function of beta cells is to produce insulin in the human body. When attacked, it destroys them and thus hinders the production of insulin in the body.

Until now, the reasons and motives for the immune system attacking beta cells are not clear to scientists, there may be genetic and environmental reasons for this.

Causes of type 2 diabetes

Type 2 diabetes begins as insulin resistance, meaning the body cannot use insulin efficiently. This stimulates the pancreas. It produces more insulin until it can no longer keep up with what the body needs.

The body fails to lower the blood sugar level by increasing insulin, so insulin production decreases, which leads to high blood sugar.

Causes of gestational diabetes

Gestational diabetes is caused by the anti-insulin hormones secreted during pregnancy. This type of diabetes occurs only during pregnancy.


Symptoms of each type of diabetes

General symptoms of diabetes

– Excessive thirst and hunger.

– Frequent urination.

– Fatigue and tiredness.

– Skin dryness and itching.

– Blurred vision.

– Slow wound healing.


DM Type II symptoms (Special symptoms)

Type 2 diabetes can cause dark spots to appear in the folds of the skin in the armpits and neck.

It takes longer to diagnose.


DM Type I symptoms

Type 1 diabetes often develops more rapidly and can cause symptoms such as weight loss or a condition called diabetic ketoacidosis.

Diabetic ketoacidosis occurs when you have very high blood sugar but have little or no insulin in your body.


The age at which symptoms appear for each type of diabetes

Symptoms of both types of diabetes (Type 1 and 2) can appear at any age, but type 1 generally occurs in children and young adults, while type 2 occurs in people over 45 years of age.


What are the possible complications of each type of diabetes?

Over time and with poor control of blood sugar levels, diabetes can lead to life-threatening complications, including:

– Vascular diseases that may lead to heart attacks or strokes.

– retinopathy

– Infection or skin disease.

– Nerve damage (neuropathy)

– Kidney damage (nephropathy)

– Amputation due to neuropathy or vascular disease.


Type 2 diabetes may increase your risk of Alzheimer’s disease, especially if your blood sugar isn’t well controlled.


Complications of diabetes during pregnancy

High blood sugar levels during pregnancy can harm both the mother and the baby, increasing the risks of:

  • High blood pressure.
  • Eclampsia.
  • Miscarriage or stillbirth.
  • Congenital malformations and defects.
