Understanding the Importance of Insulin

For individuals diagnosed with type 1 diabetes, insulin is not merely a treatment; it is a vital hormone that can be life-saving. A recent incident reported by an internal medicine expert has underscored the dire consequences of discontinuing insulin. A 26-year-old man tragically passed away from diabetic ketoacidosis (DKA) after he opted to replace his prescribed insulin injections with oral diabetes medications. This incident serves as a crucial reminder that type 1 diabetes cannot be managed solely with pills, and even a brief interruption in insulin therapy can lead to a life-threatening situation.


The Incident Involving the Young Man

What happened to the young man?

As shared by Dr. Priyam Bordoloi, an internal medicine specialist, the young man had been managing type 1 diabetes since his teenage years. Frustrated with the daily routine of insulin injections, he decided to stop using insulin altogether and began taking oral diabetes medications that he had borrowed from a family member. Unfortunately, by the time he arrived at the hospital, his health had significantly declined. His blood sugar level soared above 600 mg/dL; he was unconscious, exhibiting rapid and deep breathing, and his breath had a fruity odor—classic indicators of diabetic ketoacidosis (DKA).


The Necessity of Insulin in Type 1 Diabetes

Why is insulin essential in type 1 diabetes?

In contrast to Type 2 diabetes, where the body still produces some insulin, Type 1 diabetes is an autoimmune disorder that results in little to no insulin production by the pancreas. The absence of insulin leads to several critical issues:

  • Glucose cannot enter the cells for energy.
  • Blood sugar levels rise rapidly.
  • The body begins to break down fat for energy.
  • This process generates acidic compounds known as ketones.

Excessive ketones can dangerously acidify the blood, resulting in diabetic ketoacidosis. If not treated promptly, DKA can lead to severe dehydration, shock, coma, organ failure, and even death.


Why Oral Medications Cannot Replace Insulin

Why can't a diabetes pill replace insulin?

Many oral diabetes medications are formulated for Type 2 diabetes, where they enhance the body's ability to utilize its own insulin or stimulate insulin production. However, in Type 1 diabetes, there is virtually no insulin available to leverage. One of the most alarming aspects of DKA is its rapid progression; it can develop within hours to a couple of days, particularly if insulin doses are missed, during infections, dehydration, or pump failures. Individuals with Type 1 diabetes must never overlook persistent high blood sugar levels or delay ketone testing when glucose levels remain elevated.


Recognizing the Warning Signs of DKA

Warning signs of diabetic ketoacidosis

Immediate medical attention is crucial if someone with Type 1 diabetes exhibits any of the following symptoms:

  • Blood sugar exceeding 250 mg/dL
  • Intense thirst
  • Frequent urination
  • Nausea or vomiting
  • Severe abdominal pain
  • Rapid, deep breathing (Kussmaul breathing)
  • Fruity or nail polish-like breath odor
  • Extreme fatigue
  • Positive blood or urine ketones
  • Confusion, drowsiness, or loss of consciousness


Managing Treatment Fatigue Effectively

How to manage treatment fatigue safely?

Living with the demands of lifelong insulin therapy can be both physically and emotionally taxing. However, experts emphasize that discontinuing insulin is never a safe option. Modern diabetes care provides various tools to simplify treatment, including:
  • Insulin pens
  • Continuous glucose monitors (CGMs)
  • Insulin pumps
  • Hybrid closed-loop systems
  • Once-weekly basal insulin (for eligible patients, in conjunction with mealtime insulin)

Patients experiencing treatment fatigue should consult their diabetes care team instead of ceasing medication independently.
