Diabetes Overview – Types, Signs, and Symptoms, Causes

What exactly is diabetes?

Diabetes develops when your body’s cells are unable to absorb sugar (glucose) and utilize it for energy. As a result, more sugar accumulates in your system. This blog explains Diabetes Overview – Types, Signs, and Symptoms, Causes.

Diabetes that is not well controlled can have catastrophic effects, including damage to a variety of organs and tissues in your body, including your heart, kidneys, feet, gums, eyes, and nerves.

Types of Diabetes

Type 1, type 2, and gestational diabetes (diabetes while pregnant) are the three basic kinds of diabetes.

Type 1 Diabetes

Type 1 diabetes is mainly caused by an autoimmune disease (in which the body mistakenly fights itself) that prevents the body from producing insulin. Type 1 diabetes affects around 5-10% of people with diabetes. Type 1 diabetes symptoms might appear suddenly. Children, teenagers, and young adults are the most commonly affected. If you have type 1 diabetes, you must take insulin on a daily basis to stay alive. No one knows how to avoid type 1 diabetes right now.

Type 2 Diabetes

Your body can’t keep blood sugar at normal levels if you have type 2 diabetes because it doesn’t use insulin properly. 90% to 95% of diabetics have type 2 diabetes.

It takes many years to develop and is usually diagnosed in adulthood (but more and more in children, teens, and young adults). Because you might not notice any symptoms, it’s crucial to have your blood sugar checked if you’re at risk. Type 2 diabetes can be avoided or delayed by adopting a healthy lifestyle that includes decreasing weight, eating healthy foods, and staying active.

Gestational Diabetes

Gestational diabetes is a type of diabetes that develops for the first time during pregnancy (gestation). Gestational diabetes, like other types of diabetes, changes the way your cells use sugar (glucose). Gestational diabetes causes high blood sugar levels, which can impair your pregnancy and your baby’s health.

Since any pregnancy problem is concerning, there is some good news to report. Pregnant women can help control gestational diabetes by consuming healthy meals, changing lifestyles, exercising, and taking medication if necessary. Controlling your blood sugar helps keep you and your baby healthy and prevent a traumatic birth.

Shortly after birth, blood sugar levels in women with gestational diabetes usually return to normal. You’re more likely to acquire type 2 diabetes if you’ve had gestational diabetes. More regular blood sugar checks will be required.


Prediabetes is described as having a blood glucose level that is greater than it should be but not strong enough in a diagnosis of diabetes by your doctor. Impaired fasting glucose or insufficient glucose tolerance are some names for it.

In people with type 2 diabetes, prediabetes is almost always present. It does, however, create symptoms in a small percentage of cases. Over 84 million people over the age of 20 in the United States have pre-diabetes, and the percentage of prediabetics is rapidly rising in other countries, even though 90% of them are ignorant of their condition.

Pre-diabetes treatment can help you avoid more serious health problems like type 2 diabetes, heart, blood vessels, eye, and kidney problems.


What are some of the signs and symptoms of diabetes?

Diabetic symptoms include:

  • Eyesight problems
  • Increased hunger and exhaustion
  • Increased urination and thirst
  • Numbness or tingling in the feet or hands, as well as persistent sores
  • Weight loss that isn’t explained

Symptoms of type 1 diabetes can arise quickly, in as little as a few weeks. Type 2 diabetes symptoms usually arise over time and are so subtle that you may not even notice them. A huge majority of people with type 2 diabetes exhibit no symptoms. Some people don’t realize they have diabetes until they start experiencing symptoms like blurred vision or heart problems.

Type 1 Diabetes Symptoms

Type 1 diabetes symptoms include nausea, vomiting, and stomach pains. Type 1 diabetes symptoms can occur in a matter of weeks or months, and can be severe. Type 1 diabetes is most commonly diagnosed in childhood, adolescence, or young adulthood, but it can occur at any age or stage.

Type 2 Diabetes Symptoms

Type 2 diabetes symptoms can take years to show or feel. Some individuals are completely oblivious to any signs. Although type 2 diabetes usually affects adults, it is becoming more common among adolescents and teenagers. Since signs of type 2 diabetes can be difficult to identify, it’s critical to recognize the risk factors. Make an appointment with your doctor if you’re having any of these symptoms.

Gestational Diabetes Symptoms

Gestational diabetes (diabetes during pregnancy) often has no symptoms. Between weeks 24 and 28, if you have a kid, your doctor should check you for gestational diabetes. If required, you can make adjustments to protect your baby’s health.

Causes of Diabetes 

The food we eat is broken down into glucose by our digestive system. Beta cells in the pancreas, which produce the hormone insulin, take this glucose into our bloodstream. Diabetes develops when the body is unable to produce or utilize this hormone adequately. The following are some of the reasons why this occurs.

Beta-cell apoptosis due to autoimmunity

Our immune system may mistake insulin-producing beta cells for antigens, causing antibodies to be produced to kill them. Diabetes is frequently identified after the majority of cells have died. In this instance, the patient will require an insulin injection every day to stay alive.

Insufficient physical activity

Type 2 diabetes can be caused by a lack of exercise and obesity. According to several research, just 30 minutes of physical activity reduces your odds of developing diabetes by 30%. As a result, make sure to schedule activities such as walking and cycling into your daily schedule. Here are some diabetes exercise suggestions that may be useful.

Several medications

Certain medications, such aspsychiatric drugs, nicotinic acid,  diuretics, and others, can damage or disturb the beta cells that create insulin.

Illness or injury to the pancreas

Beta cells are found in the pancreas, and any injury or disease, such as cancer, pancreatitis, or other autoimmune diseases, can cause beta cells to stop working, resulting in diabetes.
