What Is Diabetes Mellitus?
Diabetes mellitus is a chronic metabolic disorder characterized by elevated blood sugar (glucose) levels. This occurs either because your body doesn't produce enough insulin, doesn't use insulin effectively, or both. Insulin is a hormone produced by the pancreas that allows glucose from food to enter your cells for energy. Without proper insulin function, glucose accumulates in the bloodstream, leading to serious health complications over time.
Global Epidemic
537 million adults worldwide have diabetes
Rising Prevalence
Expected to reach 783 million by 2045
Undiagnosed
50% don't know they have diabetes
Manageable
Proper management prevents complications
Types of Diabetes
Type 1 Diabetes (5-10% of cases)
- Cause: Autoimmune destruction of insulin-producing cells in pancreas
- Onset: Usually childhood or young adulthood, but can occur at any age
- Insulin: Requires lifelong insulin injections
- Risk Factors: Genetic predisposition, autoimmune triggers
- Prevention: Cannot be prevented
Type 2 Diabetes (90-95% of cases)
- Cause: Insulin resistance—body doesn't use insulin properly
- Onset: Usually adults over 45, but increasingly common in younger people
- Insulin: May not initially require insulin; managed with diet, exercise, medications
- Risk Factors: Obesity, physical inactivity, family history, age
- Prevention: Can often be prevented or delayed with lifestyle changes
Gestational Diabetes
- Cause: Hormones during pregnancy cause insulin resistance
- Onset: Develops during pregnancy (usually 2nd or 3rd trimester)
- Resolution: Usually resolves after delivery
- Risk: 50% chance of developing Type 2 diabetes within 10 years
Prediabetes
- Blood sugar higher than normal but not yet diabetes
- 96 million Americans have prediabetes
- 80% don't know they have it
- High risk of progressing to Type 2 diabetes
- Reversible with lifestyle changes!
Symptoms of Diabetes
Classic Symptoms
- Polyuria (Frequent Urination): Especially at night; kidneys work overtime to eliminate excess glucose
- Polydipsia (Excessive Thirst): Constant thirst due to fluid loss from frequent urination
- Polyphagia (Increased Hunger): Always hungry despite eating; cells aren't getting energy
- Unexplained Weight Loss: Despite eating more; body breaks down muscle and fat for energy
- Fatigue: Persistent tiredness; cells aren't getting glucose they need
- Blurred Vision: High blood sugar affects eye lens
- Slow-Healing Wounds: Cuts, sores take weeks to heal
- Frequent Infections: Yeast infections, urinary tract infections, skin infections
- Tingling or Numbness: In hands or feet (early nerve damage)
- Dark Skin Patches: Acanthosis nigricans—dark, velvety skin in armpits, neck
Type 1 vs Type 2 Symptom Onset
Type 1: Symptoms develop suddenly over weeks, often severe
Type 2: Symptoms develop gradually over years; many have no symptoms initially
Risk Factors for Type 2 Diabetes
- Overweight/Obesity: Especially abdominal fat; biggest risk factor
- Physical Inactivity: Sedentary lifestyle
- Age: Risk increases after 45
- Family History: Parent or sibling with diabetes
- Race/Ethnicity: Higher risk in African American, Hispanic, Native American, Asian American, Pacific Islander
- Gestational Diabetes: Had diabetes during pregnancy
- Polycystic Ovary Syndrome (PCOS): Women with PCOS
- Prediabetes: Already have elevated blood sugar
- High Blood Pressure: 140/90 mmHg or higher
- Abnormal Cholesterol: HDL below 35 mg/dL or triglycerides above 250 mg/dL
Diagnosis of Diabetes
Blood Tests
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| Fasting Blood Glucose (8+ hours fasting) |
Less than 100 mg/dL | 100-125 mg/dL | 126 mg/dL or higher |
| HbA1c (Average over 2-3 months) |
Below 5.7% | 5.7-6.4% | 6.5% or higher |
| Random Blood Glucose (Any time of day) |
N/A | N/A | 200 mg/dL or higher (with symptoms) |
| Oral Glucose Tolerance Test (2 hours after 75g glucose) |
Less than 140 mg/dL | 140-199 mg/dL | 200 mg/dL or higher |
Monitoring Diabetes
- HbA1c: Checked every 3-6 months; target typically below 7% (individualized)
- Home Blood Glucose: Self-monitoring with glucometer; frequency varies by treatment
- Continuous Glucose Monitor (CGM): Wearable device providing real-time glucose readings
- Ketone Testing: For Type 1 or during illness (urine or blood)
Complications of Diabetes
Uncontrolled diabetes damages blood vessels and nerves throughout the body, leading to serious complications. The good news: proper management dramatically reduces these risks.
🚨 Acute Complications—Medical Emergencies
Diabetic Ketoacidosis (DKA)
More common in Type 1; life-threatening buildup of acids (ketones) in blood
- Blood sugar usually >250 mg/dL
- Excessive thirst and urination
- Nausea, vomiting, abdominal pain
- Fruity-smelling breath
- Rapid breathing, confusion
- Requires immediate ER care—can be fatal
Hyperosmolar Hyperglycemic State (HHS)
More common in Type 2; extremely high blood sugar without ketones
- Blood sugar >600 mg/dL
- Severe dehydration
- Confusion, drowsiness
- Visual hallucinations
- Seizures or coma
- Requires immediate ER care—50% mortality if untreated
Severe Hypoglycemia
Dangerously low blood sugar (below 70 mg/dL)
- Shakiness, sweating, rapid heartbeat
- Hunger, irritability, anxiety
- Confusion, difficulty concentrating
- Severe: seizures, loss of consciousness
- Treat immediately with fast-acting carbs; call 911 if unconscious
Chronic Complications
Cardiovascular Disease
- Heart disease and stroke are leading causes of death in diabetics
- Risk 2-4 times higher than non-diabetics
- 68% of diabetics over 65 die from heart disease
- High blood pressure, abnormal cholesterol worsen risk
- Prevention: Control blood sugar, blood pressure, cholesterol; don't smoke; exercise regularly
Diabetic Nephropathy (Kidney Disease)
- Diabetes is #1 cause of kidney failure (44% of new cases)
- High blood sugar damages kidney's filtering units
- Early stages: no symptoms; protein appears in urine
- Advanced stages: fluid retention, fatigue, nausea
- End-stage: requires dialysis or kidney transplant
- Screening: Annual urine test for protein, kidney function blood test
- Prevention: Control blood sugar and blood pressure; ACE inhibitors or ARBs protect kidneys
Diabetic Retinopathy (Eye Disease)
- Leading cause of blindness in adults
- High blood sugar damages blood vessels in retina

- Peripheral neuropathy: Numbness, tingling, pain in feet/hands; most common
- Autonomic neuropathy: Affects digestive system, bladder, heart rate, sexual function
- Prevention: Control blood sugar; foot care crucial
- Treatment: Pain medications, physical therapy
Diabetic Foot Complications
Diabetic foot problems are among the most serious complications, combining nerve damage and poor circulation. Diabetes is the leading cause of non-traumatic lower limb amputations—but 85% are preventable with proper care.
Why Diabetes Affects Feet
- Neuropathy: Nerve damage causes numbness—can't feel injuries, pressure, temperature
- Poor Circulation: Damaged blood vessels reduce blood flow—slow healing
- Reduced Immunity: High blood sugar impairs infection-fighting ability
- Foot Deformities: Nerve damage changes foot shape, creating pressure points
Common Diabetic Foot Problems
Ulcers (Open Sores)
- 15% of diabetics develop foot ulcers
- Usually on ball of foot or bottom of big toe
- Often painless due to neuropathy
- Can become infected, lead to amputation
- 6% of ulcers require hospitalization
Infections
- Even minor cuts can become serious infections
- Can spread to bone (osteomyelitis)
- May require IV antibiotics, surgery
- Gangrene develops if blood flow severely reduced
Charcot Foot
- Bones weaken and fracture, leading to deformity
- Foot becomes swollen, red, warm
- Often painless due to neuropathy
- Requires immediate treatment to prevent permanent deformity
Other Problems
- Calluses and corns (thickened skin at pressure points)
- Blisters
- Ingrown toenails
- Fungal infections (athlete's foot)
- Dry, cracked skin
Daily Foot Care for Diabetics
Essential Daily Routine
- Inspect feet daily: Check for cuts, blisters, redness, swelling. Use mirror for bottoms of feet
- Wash feet daily: Use warm (not hot) water and mild soap. Test water with elbow
- Dry thoroughly: Especially between toes (prevent fungal infections)
- Moisturize: Apply lotion to tops and bottoms (not between toes)
- Trim toenails carefully: Cut straight across, file edges. See podiatrist if you can't see well
- Never go barefoot: Even indoors—protect feet from injury
- Wear proper footwear: Well-fitting shoes and socks without tight elastic
- Check shoes before wearing: Feel inside for foreign objects, rough seams
When to See a Doctor Immediately
🚨 Emergency Foot Warning Signs
- Any cut, blister, or sore on foot
- Redness, warmth, or swelling
- Pain in legs or feet (even when resting)
- Ingrown toenail with redness or pus
- Corns or calluses with redness or drainage

- Vascular assessment: Checks circulation
- Therapeutic shoes: Special diabetic shoes if high risk
- Regular podiatry visits: If neuropathy, deformities, or previous ulcers
Diabetic Kidney Disease (Nephropathy)
Diabetic nephropathy is kidney damage caused by diabetes—the leading cause of kidney failure requiring dialysis or transplant. One in three adults with diabetes has chronic kidney disease, but early detection and treatment can prevent progression.
Stages of Diabetic Kidney Disease
| Stage | Description | GFR (mL/min) | Symptoms |
|---|---|---|---|
| Stage 1 | Kidney damage with normal function | 90+ | None; protein in urine |
| Stage 2 | Mild decrease in function | 60-89 | Usually none |
| Stage 3 | Moderate decrease in function | 30-59 | Fatigue, swelling, frequent urination |
| Stage 4 | Severe decrease in function | 15-29 | Swelling, shortness of breath, nausea, poor appetite |
| Stage 5 | Kidney failure | Below 15 | Severe symptoms; requires dialysis or transplant |
Symptoms of Kidney Disease
Early stages often have no symptoms. As disease progresses:
- Swelling in ankles, feet, hands, face
- Foamy or bubbly urine (protein leakage)
- Frequent urination, especially at night
- Difficulty concentrating
- Poor appetite, metallic taste
- Fatigue and weakness
- Nausea and vomiting
- Itchy skin
- Muscle cramps
- High blood pressure that's hard to control
Screening and Diagnosis
- Urine albumin test: Checks for protein in urine; annually for diabetics
- Serum creatinine: Blood test measuring kidney function
- eGFR calculation: Estimates kidney filtration rate
- Kidney ultrasound: If abnormal test results
Treatment and Prevention
Protecting Your Kidneys
- Control blood sugar: HbA1c below 7% (individualized target)
- Control blood pressure: Target below 140/90 (usually below 130/80 for diabetics)
- ACE inhibitors or ARBs: Blood pressure medications that protect kidneys
- SGLT2 inhibitors: Diabetes medications with kidney protection benefits
- Low-protein diet: May slow progression in advanced stages
- Limit salt: Under 2,300 mg daily
- Stay hydrated: Adequate water intake
- Avoid NSAIDs: Ibuprofen, naproxen can harm kidneys
- Don't smoke: Smoking accelerates kidney damage
Dialysis and Transplant
When kidneys fail (Stage 5), two options exist:
Dialysis
- Hemodialysis: Machine filters blood; 3x per week, 3-4 hours per session
- Peritoneal dialysis: Uses abdominal lining to filter blood; done at home daily
- Lifesaving but requires significant lifestyle adjustments
- Strict dietary and fluid restrictions
Kidney Transplant
- Best long-term option
- Can be from living or deceased donor
- Success rate: 90%+ at one year
- Requires lifelong immunosuppressive medications
- Waiting time varies (average 3-5 years for deceased donor)
Management of Diabetes
Blood Sugar Targets
| Measurement | Target for Most Adults | Notes |
|---|---|---|
| Fasting/Before Meals | 80-130 mg/dL | Check in morning before eating |
| 2 Hours After Meals | Less than 180 mg/dL | Peak blood sugar |
| HbA1c | Below 7% | Individualized; some need stricter/looser control |
| Bedtime | 90-150 mg/dL | Prevents overnight hypoglycemia |
Medications for Type 2 Diabetes
Oral Medications
- Metformin: First-line therapy; reduces liver glucose production; minimal hypoglycemia risk; may cause GI upset initially

- SGLT2 inhibitors: Cause kidneys to excrete glucose; weight loss benefit; protect heart and kidneys
- Thiazolidinediones: Improve insulin sensitivity; weight gain, fluid retention
Injectable Medications
- GLP-1 agonists: Slow digestion, increase insulin; weight loss benefit; protect heart; weekly or daily injection
- Insulin: Multiple types (rapid, short, intermediate, long-acting); required for Type 1, sometimes Type 2
Insulin Therapy
Essential for Type 1; needed by some Type 2 diabetics
Types of Insulin
| Type | Onset | Peak | Duration |
|---|---|---|---|
| Rapid-Acting | 10-15 min | 1-2 hours | 3-5 hours |
| Short-Acting | 30 min | 2-3 hours | 6-8 hours |
| Intermediate | 1-2 hours | 4-6 hours | 12-18 hours |
| Long-Acting | 1-2 hours | No peak | 20-24+ hours |
Insulin Delivery

Frequently Asked Questions
In some cases, yes—through remission. Significant weight loss (10-15% of body weight) through diet and exercise can put Type 2 diabetes into remission, meaning blood sugar returns to normal without medications. However, this requires maintaining weight loss and healthy habits. Not all Type 2 diabetics can achieve remission, especially if disease is long-standing.
Yes, occasionally and in moderation. Diabetes doesn't mean never eating sweets again. The key is portion control, planning (work it into your carb budget), and choosing the right time (after a meal, not alone). Consider sugar-free alternatives, share desserts, and always check blood sugar after to see how your body responds.
Diabetic neuropathy causes numbness, so you might not feel injuries. A small cut or blister can quickly become infected and lead to serious complications, even amputation. Daily inspection allows early detection of problems when they're easily treatable. Check for cuts, blisters, redness, swelling, or any changes.
It varies: Type 1 or insulin users: typically 4-10 times daily (before meals, bedtime, sometimes 2 hours after meals, before/after exercise). Type 2 on oral medications: varies widely, often daily fasting check or periodic testing. Your doctor will recommend a schedule based on your treatment plan. Continuous glucose monitors reduce finger-stick needs.
Type 1: Always requires insulin immediately. Type 2: It's progressive—about 50% eventually need insulin as pancreas produces less over time. This doesn't mean you've failed; it's natural disease progression. Starting insulin when needed actually protects remaining pancreas function and prevents complications.
In moderation, usually yes. Limit to 1 drink/day (women) or 2/day (men). Critical rules: never drink on empty stomach (causes hypoglycemia), check blood sugar before/after, carry glucose source, wear medical ID. Avoid sugary mixed drinks. Some medications interact with alcohol—ask your doctor.
Not contagious—you can't catch diabetes. However, genetics play a role: Type 1 risk is 5-10% if parent or sibling has it. Type 2 has stronger genetic link—if one parent has it, 50% chance; both parents, 75% chance. But Type 2 is largely preventable through lifestyle, even with genetic risk.
Type 1: Autoimmune—body destroys insulin-producing cells; produces no insulin; requires insulin injections; usually starts young; cannot be prevented. Type 2: Insulin resistance—body doesn't use insulin properly; may still produce insulin; often manageable with lifestyle/oral medications initially; usually starts later; largely preventable.
Yes, with careful planning and management. Preconception: achieve good blood sugar control (HbA1c <6.5%) before conceiving. During pregnancy: requires frequent monitoring, medication adjustments, regular ultrasounds. Higher risk of complications but majority have healthy pregnancies and babies with proper care. Work closely with maternal-fetal medicine specialist.
Preventing Type 2 Diabetes
If you have prediabetes, you can prevent or delay Type 2 diabetes. Studies show lifestyle changes reduce diabetes risk by 58% (71% in people over 60).
Proven Prevention Strategies
- Lose 5-7% of body weight: For 200-pound person, that's just 10-14 pounds
- Exercise 150 minutes weekly: 30 minutes, 5 days per week
- Eat healthy diet: Whole grains, vegetables, lean protein; limit refined carbs and sugar
- Don't smoke: Smoking increases diabetes risk 30-40%
- Limit alcohol: Excessive drinking increases risk
- Get adequate sleep: Sleep deprivation increases diabetes risk
- Manage stress: Chronic stress affects blood sugar and weight
- Medications: Metformin reduces risk 31% in high-risk individuals
Who Should Be Screened for Diabetes?
- All adults age 45 and older (every 3 years)
- Adults under 45 who are overweight/obese with additional risk factors
- Women with history of gestational diabetes (every 1-3 years)
- Anyone with symptoms of diabetes
- People with prediabetes (annually)
- Anyone diagnosed with heart disease, stroke, PCOS
