Diabetes is a persistent health issue impacting the body's ability to convert food into energy. In diabetic conditions, the body either produces insufficient insulin or fails to utilize the insulin it generates efficiently.
Insulin is a hormone in your pancreas that allows cells to use glucose from carbohydrates for energy. Insufficient insulin production or diminished cellular response to insulin results in elevated levels of blood sugar remaining in the bloodstream. This prolonged condition can contribute to severe health complications over time.
There are two main types of diabetes: type 1 and type 2. While both involve insulin problems and high blood sugar, there are important distinctions between them.

What is Type 1 Diabetes?
With type 1 diabetes, your body simply stops producing enough insulin. It typically develops in children and young adults. Type 1 diabetes only accounts for about 5-10% of people who have diabetes.
In Type 1 diabetes, the immune system gradually targets and eradicates the pancreas's insulin-producing cells. Consequently, the pancreas loses its ability to produce insulin altogether. The causes are still unclear, but genetics and environmental factors appear to play a role in its development.
There's no way to prevent type 1 diabetes. The disease progresses quickly, and the symptoms can appear suddenly. The symptoms may include:
- Frequent urination
- Intense thirst and hunger
- Unintended weight loss
- Mood changes
- Fatigue
- Headaches and blurred vision
People with type 1 diabetes need to take daily insulin via injections or an insulin pump. Taking insulin is necessary for survival because their bodies don't produce it independently. Along with insulin therapy, following a balanced meal plan focused on carb counting and healthy lifestyle habits can help manage this type of diabetes.
What is Type 2 Diabetes?
Type 2 diabetes develops over many years and affects how well your cells can use insulin. With type 2, your pancreas still produces insulin. However, your cells become resistant, meaning the insulin can't trigger them to remove sufficient glucose from the bloodstream. So, too much glucose accumulates in the blood over time, leading to high blood sugar levels. Often, people don't realize they have type 2 diabetes until they develop complications or get a routine blood test at the doctor's office.
The exact causes of type 2 diabetes are complex. Genetics, excess weight, age over 45, lack of exercise, family history, and race can increase your risk. You can reduce your risk through lifestyle steps like losing a modest amount of weight, increasing physical activity, and eating a balanced diet focused on whole grains, vegetables, and lean proteins. If diet and exercise aren't enough to control it, your doctor may prescribe medications like metformin to help lower blood sugar levels.
Metformin works by reducing glucose production in the liver and improving insulin sensitivity in muscle tissues. Like all medications, though, it does come with potential side effects. Metformin side effects may include diarrhea, nausea, or abdominal discomfort, especially when first starting the medication.
Type 2 diabetes is the most common form of diabetes, accounting for 90-95% of cases. Many Americans have prediabetes (higher than normal blood sugar levels) but not full-blown diabetes. Paying attention to prediabetes risk factors is important, as many cases can be delayed or prevented through lifestyle improvements.
Comparing Type 1 vs Type 2 Symptoms and Treatment Approaches
While both involve the hormone insulin and problems regulating blood sugar levels, there are important differences in symptoms and treatment between type 1 and type 2 diabetes:
Onset – Type 1 typically develops quickly in children/young adults, versus type 2, which slowly progresses over many years in adults over 45 years old. However, more young people are now developing type 2 diabetes, coinciding with rising childhood obesity rates.
Cause – Type 1 stems from the autoimmune destruction of insulin-producing cells in the pancreas, while type 2 relates more excess weight/lifestyle factors and genetics interfering with insulin effectiveness.
Insulin dependence – People with type 1 diabetes are insulin-dependent for survival and receive insulin via injections or pumps. Many people with type 2 can manage through oral medication, lifestyle and diet changes. Over time, some type 2 patients may eventually need insulin therapy if their bodies stop producing enough on their own.
Reversibility - Type 1 requires lifelong insulin treatment. Early treatment of prediabetes and type 2 diabetes can reverse high blood sugar levels or put the diseases in remission through substantial lifestyle improvements focused on nutrition, activity levels, sleep, and stress reduction. That’s why education on diabetes prevention through lifestyle is so important.
See your doctor promptly if you notice potential diabetes symptoms like:
- Increased thirst/appetite.
- Frequent urination.
- Weight changes.
- Fatigue.
Pay attention to risk factors, especially for type 2, since early changes can be subtle. Getting evaluated quickly for diabetes or prediabetes allows early treatment to prevent complications.
Understanding the differences between type 1 and type 2 diabetes leads to better conversations with your doctor about symptoms, treatments, and lifestyle recommendations tailored to your type. Individuals can take proactive steps to maintain their health and well-being by recognizing the unique symptoms, causes, and treatment approaches for each type.
Engaging in open conversations with healthcare providers empowers individuals to make informed decisions and adopt lifestyle changes tailored to their diabetes type, ultimately leading to better outcomes and improved quality of life.
