What is Diabetes and How Does It Affect Your Health?

Diabetes is a chronic metabolic disorder that occurs when the body either does not produce enough insulin or cannot effectively use the insulin it produces. Insulin is a hormone responsible for regulating blood sugar levels. Without proper insulin function, blood sugar (glucose) builds up in the bloodstream, leading to various health complication

Different Types of Diabetes and Their Descriptions

Diabetes is a complex group of diseases that affect how the body regulates blood sugar (glucose). While type 1 and type 2 diabetes are the most well-known, there are several other types, each with unique causes and characteristics.

1. Type 1 Diabetes

  • Cause: Autoimmune disorder where the immune system attacks insulin-producing beta cells in the pancreas.
  • Onset: Typically develops in childhood or adolescence but can occur at any age.
  • Symptoms: Frequent urination, excessive thirst, unexplained weight loss, fatigue, and high blood sugar levels.
  • Treatment: Requires lifelong insulin therapy and blood sugar monitoring

2. Type 2 Diabetes

  • Cause: The body becomes resistant to insulin or does not produce enough insulin.
  • Onset: Usually develops in adults, but increasing cases are seen in children due to obesity and sedentary lifestyles.
  • Symptoms: Increased thirst, frequent urination, fatigue, slow-healing wounds, and blurred vision.
  • Treatment: Managed with lifestyle changes, oral medications, and sometimes insulin therapy.

3. Gestational Diabetes

  • Cause: Hormonal changes during pregnancy cause insulin resistance.
  • Onset: Develops during pregnancy and usually resolves after childbirth.
  • Symptoms: Often asymptomatic; diagnosed through routine glucose testing.
  • Risks: Can lead to complications for both mother and baby and increases the risk of type 2 diabetes later in life.
  • Treatment: Controlled through diet, exercise, and sometimes insulin.

4. Maturity Onset Diabetes of the Young (MODY)

  • Cause: Genetic mutations affecting insulin production.
  • Onset: Usually diagnosed in adolescence or early adulthood.
  • Symptoms: Similar to type 2 diabetes but occurs in non-obese individuals.
  • Treatment: Varies based on the specific genetic mutation; may include oral medications or insulin.

5. Neonatal Diabetes

  • Cause: Genetic mutation affecting insulin production in newborns.
  • Onset: Occurs in the first six months of life.
  • Symptoms: Failure to thrive, dehydration, and high blood sugar levels.
  • Treatment: Some cases respond to oral medications, while others require insulin therapy.

6. Wolfram Syndrome

  • Cause: A rare genetic disorder affecting insulin production and neurological function.
  • Onset: Childhood or adolescence.
  • Symptoms: Diabetes, vision loss, hearing impairment, and nervous system disorders.
  • Treatment: No cure; management focuses on controlling blood sugar and supportive care for associated symptoms.

.

7. Alström Syndrome

  • Cause: A rare genetic disorder affecting multiple organs, including the pancreas.
  • Onset: Early childhood.
  • Symptoms: Type 2 diabetes, vision and hearing loss, obesity, and heart disease.
  • Treatment: No cure; symptoms are managed with medications, lifestyle changes, and supportive therapies.

 

8. Latent Autoimmune Diabetes in Adults (LADA)

  • Cause: Slow-progressing autoimmune destruction of insulin-producing cells.
  • Onset: Usually diagnosed in adulthood (often misdiagnosed as type 2 diabetes).
  • Symptoms: Gradual increase in blood sugar levels, initially managed with oral medications but eventually requiring insulin.
  • Treatment: Initially managed with oral drugs but later needs insulin therapy.

9. Type 3c Diabetes

  • Cause: Damage to the pancreas due to conditions like pancreatitis, pancreatic surgery, or cystic fibrosis.
  • Onset: Can occur at any age, depending on pancreatic damage.
  • Symptoms: Similar to type 2 diabetes but with additional digestive issues due to enzyme deficiencies.
  • Treatment: Requires insulin therapy and pancreatic enzyme replacement therapy (PERT)

10. Steroid-Induced Diabetes

  • Cause: Long-term use of corticosteroids like prednisone, which increases insulin resistance.
  • Onset: Develops in individuals using steroids for other medical conditions.
  • Symptoms: High blood sugar, frequent urination, increased thirst, and fatigue.
  • Treatment: Blood sugar control through diet, medications, and sometimes insulin.

11. Cystic Fibrosis-Related Diabetes (CFRD)

  • Cause: Scarring and damage to the pancreas due to cystic fibrosis.
  • Onset: Usually develops in adolescence or adulthood in cystic fibrosis patients.
  • Symptoms: Combination of diabetes and digestive issues, including weight loss and malnutrition.
  • Treatment: Insulin therapy, pancreatic enzyme supplements, and a high-calorie diet

Effects of Diabetes on Your Health

If left unmanaged, diabetes can lead to serious health complications, including:

  • Heart Disease & Stroke – High blood sugar damages blood vessels, increasing the risk of heart attacks and strokes.
  • Kidney Damage (Nephropathy) – Diabetes is a leading cause of kidney failure.
  • Nerve Damage (Neuropathy) – Can cause tingling, numbness, and even loss of sensation, particularly in the feet.
  • Eye Problems (Retinopathy) – High blood sugar can lead to vision loss and blindness.
  • Slow Healing & Infections – Wounds, especially on the feet, heal slowly and may lead to severe infections.

Diabetes, together with cardiovascular disease (CVD), cancer and chronic respiratory disease has been targeted in the Political Declaration on the Prevention and Control of Noncommunicable Diseases (NCDs) at the Un High-level Political Meeting in 2011. In 2013, the WHO member states endorsed a global monitoring framework for NCDs, with 9 targets to be reached by 2025. Diabetes and its key risk factors are strongly reflected in the targets and indicators – reduction of exposure to unhealthy diet and physical inactivity, zero rise in the prevalence of diabetes, improved access to treatment, and reduction of premature mortality. As part of the 2030 Agenda for Sustainable Development, Member States have set an ambitious target to reduce premature mortality from NCDs – including diabetes – by one-third; achieve universal health coverage, and provide access to affordable essential medicines – all by 2030 (http://www.un.org/sustainabledevelopment/sustainable-development-goals/).

Managing Diabetes

Managing diabetes involves a combination of a healthy diet, regular exercise, blood sugar monitoring, and, in some cases, medications or insulin therapy. Early detection through regular testing can help prevent complications and improve quality of lifec
