Overview:
Around 537 million people are living with diabetes across the globe. This number is predicted to rise to 643 million by 2030.
Diabetes is a complicated condition in which your blood sugar level is too high.
There are several types of diabetes. The three main types of diabetes are type 1 diabetes, type 2 diabetes, and gestational diabetes. Apart from these three main types of diabetes, there are also other types of diabetes.
Understanding the differences between these types of diabetes is crucial for effective management, as each type demands a unique combination of treatments, lifestyle adjustments, and monitoring.

Main Types Of Diabetes:
The three main types of diabetes include:
Type 1 Diabetes:
In type 1 diabetes, your body loses the ability to produce the insulin hormone that drives sugar from your bloodstream into your cells.
It is caused by an autoimmune process, in which your immune system mistakenly attacks and destroys the beta cells in your pancreas that produce insulin.
This damage is permanent and your body will not make any insulin. 5 to 10% of people with diabetes have type 1 diabetes.
However, your body still breaks down the carbohydrates from your food and drink and turns them into glucose(sugar).
But when glucose enters your bloodstream in the absence of insulin, your body will not be able to drive glucose into your cells, resulting in the build-up of glucose in the bloodstream.
Causes of type 1 diabetes:
- Autoimmune responses
- Genetic factors
- Certain infections
- Environmental factors
Symptoms of type 1 diabetes:
- Increased thirst
- Frequent urination
- Extreme hunger
- Unintended weight loss
- Blurred vision
- Frequent infections
- Slow-healing sores
Type 2 Diabetes:
In type 2 diabetes, your body becomes resistant to insulin or can’t produce enough insulin to maintain normal sugar(glucose) levels.
It means, your body’s cells don’t respond to insulin efficiently. So your body produces more insulin to overcome resistance which can damage your pancreas and your body may not produce enough insulin, causing an accumulation of sugar(glucose) in your bloodstream. 90 to 95% of people with diabetes have type 2 diabetes.
Causes of type 2 diabetes:
- Insulin Resistance
- Genetics
- Obesity
- Age
- Ethnicity
- Unhealthy diet
- Physical inactivity
- Certain medical conditions
Symptoms of type 2 diabetes:
- Excessive thirst
- Fatigue
- Constant hunger
- A lack of energy
- Frequent urination
- Weight loss without trying
- Dark rashes around your neck or armpits
- Numbness or tingling in the hands or feet
Gestational Diabetes:
Gestational diabetes only develops during pregnancy. It generally goes away after giving birth. About 50% of people with gestational diabetes are at higher risk of getting type 2 diabetes.
Causes of gestational diabetes:
- Hormonal change during pregnancy
- Insulin resistance
- Genetic factors
- Multiple pregnancies
- Excess weight
- Stress
Symptoms of gestational diabetes:
- Increased thirst
- Frequent urination
- Fatigue
- Blurred vision
- Unusual hunger
- Dry mouth
- Nausea and vomiting
- Frequent infections (e.g., urinary tract infections, yeast infections)
- Sugar in urine (often detected during routine prenatal visits)
It’s important to note that many women with gestational diabetes may not experience noticeable symptoms, and the condition is often detected through routine screening during
pregnancy.
Other Types Of Diabetes:
Apart from the three main types of diabetes, there are some other types of diabetes that constitute around 1 to 2% of diabetes patients. These other types of diabetes include:
Type 3c Diabetes:
People develop type 3c diabetes when their pancreas is damaged due to some diseases such as pancreatic cancer, pancreatitis, cystic fibrosis, or hemochromatosis.
Steroid-Induced Diabetes:
Some people who take steroids can develop this diabetes. Steroids increase the sugar levels in the blood. Some people can get relief from this diabetes after they stop taking steroids, while in some people, it can continue even after not taking steroids.
Cystic Fibrosis Diabetes:
It is the most common type of diabetes in people with cystic fibrosis. This diabetes has the features of both type 1 and type 2 diabetes.
Monogenic Diabetes:
Monogenic diabetes is a rare condition, that is caused by a mutation in a single gene. If a parent has this mutation, their children have a 50% chance of inheriting it.
There are two types of monogenic diabetes:
- Neonatal Diabetes
- Maturity onset diabetes of the young (MODY)
Potential Complications:
If diabetes is not managed properly, it can lead to life-threatening serious complications including:
- Nerve damage (neuropathy)
- Kidney damage (nephropathy)
- Eye damage, retinal damage (retinopathy)
- Cardiovascular diseases like heart attack, heart stroke, and high blood pressure.
How different types of diabetes are treated?
Diabetes treatment varies depending on the type of diabetes a person has. However, in every treatment, the main goal is to keep your sugar levels within a healthy range. Here’s an overview of how each type of diabetes is managed:
Type 1 Diabetes:
- Insulin Therapy: Since in type 1 diabetes, the body doesn’t produce insulin, individuals need to take insulin through injections or an insulin pump. There are different types of insulin (rapid-acting, long-acting, etc.), and a treatment plan usually includes a combination of these.
- Diet and Exercise: Taking a healthy diet and regular physical activity helps manage blood sugar levels and overall health. Carbohydrate counting is often used to manage the intake of carbs, which impact blood glucose.
- Blood Sugar Monitoring: Regular monitoring of blood glucose levels is essential to manage type 1 diabetes. This helps in adjusting insulin doses and managing diet and exercise.
- Continuous Glucose Monitoring (CGM): CGMs can provide real-time blood sugar readings, helping in more precise insulin dosing.
Type 2 Diabetes:
- Lifestyle Changes: Lifestyle changes play a crucial role in managing your type 2 diabetes. Incorporating a healthy diet(Such as whole grains, fruits, and vegetables), exercise, and weight loss helps you manage type 2 diabetes.
- Oral Medications: In some cases, if you are not able to maintain your sugar level through lifestyle changes, you need medications.
- Insulin Therapy: In some cases, people with type 2 diabetes may require insulin, particularly if lifestyle changes and other medications are not sufficient to control blood sugar levels.
- Blood Sugar Monitoring: Regular monitoring helps in adjusting medications, diet, and activity levels.
Gestational Diabetes:
- Diet and Exercise: A healthy diet and regular physical activity are the first steps in managing gestational diabetes. The goal is to keep blood sugar levels within a target range.
- Blood Sugar Monitoring: Regular monitoring is important to ensure that blood sugar levels remain stable.
- Insulin Therapy: Insulin therapy may be needed if diet and exercise aren’t enough to manage blood sugar. Only a small number of women with gestational diabetes need insulin. Some oral medications are also used, but insulin is the most common treatment.
Prevention:
Type 1 Diabetes:
Currently, there is no known prevention for type 1 diabetes, it can only be managed.
Type 2 Diabetes:
Adopting a healthy lifestyle can reduce your chances of developing type 2 diabetes. These healthy lifestyles include:
- Healthy diet: Eating healthy and nutritious foods that are rich in fiber, minerals, vitamins, and healthy fats and carbs helps you prevent type 2 diabetes.
- Physical Activity: Exercise for at least 30 minutes a day can help you prevent type 2 diabetes.
- Weight loss: If you are overweight, losing just 5 to 7% of your body weight can lower or prevent your risk of getting type 2 diabetes.
Gestational Diabetes:
Adopting above mentioned healthy lifestyles is also helpful in preventing gestational diabetes.
The Bottom Line:
Diabetes is a complex and multifaceted condition with different types, each requiring specific approaches to treatment and management.
Since type 1 diabetes has no cure till now, so it can only be managed. It requires lifelong insulin therapy due to the body’s inability to produce insulin. However, with a healthy lifestyle, one could prevent severe complications of type 1 diabetes.
Type 2 diabetes can be prevented and managed successfully by adopting a healthy lifestyle that includes a healthy diet, exercise, and weight loss.
Gestational diabetes that develops during pregnancy usually goes away after giving birth. But, it requires careful monitoring and management to protect both mother and child.
By recognizing the specific needs of each type, individuals with diabetes can work closely with healthcare providers to develop a personalized plan that promotes optimal health and minimizes the risk of complications.
FAQs:
1. What are the main types of diabetes?
There are three main types of diabetes:
- Type 1 Diabetes: An autoimmune condition where the body attacks insulin-producing cells in the pancreas.
