Understanding Endocrine and Metabolic Conditions

Learn about a wide range of hormonal, adrenal, thyroid, and metabolic conditions. Each article provides clear, concise information to help you better understand the causes, symptoms, and potential health impacts of these disorders.

Type 1 Diabetes Mellitus (T1DM)

Overview

Type 1 diabetes mellitus (T1DM) is a chronic autoimmune condition in which the body’s immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. Without insulin, the body cannot effectively regulate blood glucose levels, leading to high blood sugar (hyperglycemia). Type 1 diabetes typically develops in childhood or adolescence, but it can occur at any age.


Causes and Risk Factors

The exact cause of T1DM is not fully understood, but it is believed to result from a combination of genetic predisposition and environmental triggers, such as viral infections. It is not caused by diet or lifestyle. Key risk factors include:

  • Family history of type 1 diabetes
  • Presence of autoantibodies
  • Certain genetic markers (e.g., HLA-DR3 and HLA-DR4)


Symptoms

Symptoms of type 1 diabetes often appear suddenly and can include:

  • Excessive thirst and urination
  • Unexplained weight loss
  • Fatigue
  • Blurred vision
  • Increased hunger
  • Fruity-smelling breath (due to ketones)
  • Nausea and vomiting (if diabetic ketoacidosis develops)


Diagnosis

T1DM is diagnosed through a combination of:

  • Blood glucose tests: Fasting glucose >126 mg/dL or random glucose >200 mg/dL with symptoms
  • HbA1c test: ≥6.5%
  • Autoantibody testing: Identifies autoimmune markers (e.g., GAD65, ICA, IA-2)
  • C-peptide test: Low levels indicate reduced insulin production


Complications

Without proper management, type 1 diabetes can lead to both acute and long-term complications:

  • Acute: Diabetic ketoacidosis (DKA), severe hypoglycemia
  • Chronic: Neuropathy, nephropathy, retinopathy, cardiovascular disease


Treatment

Management of T1DM requires lifelong insulin therapy through injections or an insulin pump, along with careful blood glucose monitoring. Other key components include:

  • Carbohydrate counting
  • Regular physical activity
  • Continuous glucose monitoring (CGM)
  • Diabetes education and support
