What is Diabetes?
Diabetes is a chronic condition where the body cannot regulate blood sugar (glucose) properly. This condition may be either due to the inability to make insulin or use it effectively.
Millions live with diabetes, but not all diabetes is the same. Here’s a simple comparison to understand Type 1 and Type 2— their causes, symptoms, and treatments.
Type 1 Diabetes
Type 1 Diabetes occurs as a result of an autoimmune reaction that attacks the beta cells of the pancreatic islet. In other words, the pancreas cannot make insulin. Mostly occurring at early ages, later occurrences are also possible
Summary
Cause: Autoimmune reaction destroys insulin-producing beta cells in the pancreas.
Onset: Often childhood or adolescence, but can occur at any age.
Insulin: Required for life, since the body produces no insulin.
Cause not linked to lifestyle.
Type 2 Diabetes
In a normal scenario, an increase in blood sugar would occur after your hunger is satisfied by eating. For homeostatic balance in the body, the blood sugar increase has to be decreased. Insulin is the hormone that does this job.
In Type 2 diabetes, although the beta cells of the pancreatic islet may make insulin, but they do not seem to respond normally to an increase in blood glucose, such that the beta cells do not release insulin (They are not able to properly detect the elevated blood glucose levels). Hence, blood sugar levels remain elevated. This form of diabetes tends to be more prevalent than Type 1.
Summary
Cause: The body becomes insulin resistant or doesn’t produce enough insulin.
Onset: More common in adults over 40, but rising in teens due to obesity & inactivity.
Insulin: May not be needed at first. Managed with lifestyle, oral meds, or insulin later.
Strong link to lifestyle factors (diet, exercise, weight).
Key Differences:
Features | Type 1 | Type 2 |
Causes | Autoimmune | Insulin resistance |
Insulin production | None | Reduced/ineffective |
Onset age | Childhood/teen | Adulthood (but changing) |
Treatment | Require insulin for life | Lifestyle, medication |
Reversible ? | No | Sometimes (with lifestyle) |
Key Similarities:
Symptoms (Type 1 and 2):
Excessive thirst
Frequent urination
Extreme fatigue
Blurry vision
Slow healing
Unexplained weight loss (more common in Type 1)
Treatment Goals (Type 1 and 2):
Maintain healthy blood sugar levels
Prevent complications (heart, kidney, nerve issues)
Support overall well-being through diet, movement, and monitoring
Key Takeaway:
Type 1 and Type 2 may share a name, but they’re very different conditions. Understanding the difference is key to managing, preventing, or supporting someone with diabetes.
