⚖️ 1. What is Diabetes Mellitus?

Diabetes is a chronic metabolic disorder characterized by high blood glucose levels due to defects in insulin secretion, insulin action, or both.

Types of Diabetes:

  • Type 1 Diabetes: Autoimmune destruction of pancreatic beta cells → absolute insulin deficiency

  • Type 2 Diabetes: Insulin resistance + relative insulin deficiency

  • Gestational Diabetes: Hyperglycemia first detected during pregnancy

  • Others: MODY, pancreatic diabetes, drug-induced diabetes

📊 2. Global and Indian Scenario

  • Over 537 million adults globally have diabetes (IDF 2021)

  • India has >77 million diabetics, projected to be 134 million by 2045

  • Known as the "Diabetes Capital of the World"

📊 3. Risk Factors

  • Non-modifiable: Age >45, genetics, ethnicity

  • Modifiable: Obesity, sedentary lifestyle, poor diet, stress, smoking, alcohol

🔎 4. Diagnosis of Diabetes

TestDiagnostic Criteria
Fasting Plasma Glucose (FPG)≥ 126 mg/dL
2-hr OGTT (75g)≥ 200 mg/dL
HbA1c≥ 6.5%
Random Plasma Glucose≥ 200 mg/dL + symptoms

Prediabetes:

  • FPG: 100-125 mg/dL

  • HbA1c: 5.7-6.4%

🚑 5. Clinical Features

  • Polyuria, polydipsia, polyphagia

  • Weight loss (Type 1)

  • Fatigue, blurred vision

  • Recurrent infections, delayed wound healing

  • In Type 2: Often asymptomatic for years

🔬 6. Investigations and Monitoring

  • HbA1c: Glycemic control (3-month average)

  • Lipid profile, renal function, urine microalbumin

  • Fundus exam, foot exam, ECG

🧳 7. Complications

Acute:

  • Diabetic ketoacidosis (DKA)

  • Hyperosmolar hyperglycemic state (HHS)

  • Hypoglycemia

Chronic:

  • Microvascular: Retinopathy, nephropathy, neuropathy

  • Macrovascular: CAD, stroke, PVD

🩺 8. Treatment Overview

Type 1 Diabetes:

  • Requires insulin therapy for life

  • Blood glucose monitoring

  • Diet + exercise + education

Type 2 Diabetes:

  • Lifestyle modification: Diet, weight loss, physical activity

  • Oral hypoglycemics:

    • Metformin: First-line

    • Sulfonylureas, DPP-4 inhibitors, SGLT2 inhibitors, GLP-1 agonists

  • Insulin: In advanced disease or poor control

Gestational Diabetes:

  • Diet, insulin if needed, post-partum follow-up

📌 9. Targets in Diabetes

ParameterTarget
FPG80-130 mg/dL
PPG<180 mg/dL
HbA1c<7% (individualized)
BP<140/90 mmHg (or <130/80)
LDL<100 mg/dL (or <70 in CVD)

🏥 10. Role of Family Physicians

  • Early detection & screening

  • Lifestyle counseling

  • Rational drug prescribing

  • Preventing complications

  • Referral when necessary

🔄 11. Lifestyle and Preventive Strategies

  • 30 mins/day brisk walking

  • Balanced low-calorie diet

  • Avoid sugar-rich & fried foods

  • Quit smoking & alcohol

  • Regular check-ups

🖊️ 12. Conclusion

Diabetes is not just a disease but a lifestyle challenge. It requires multidisciplinary, continuous care. With proper screening, early intervention, lifestyle change, and individualized treatment, we can delay complications and improve quality of life.

“Empowering patients through education is the cornerstone of diabetes care.”

🏥 Insulin Storage: Myths vs. Facts Every Diabetic Should Know

-
By Dr. Sk Sabir Rahaman, MBBS , MD (Pharmacology), DFM(Family Medicine), FCFM, CCEBDM, CCLSD   For millions living with diabetes, insulin is more than a medication — it’s a lifeline . However, widespread misconceptions about insulin storage often lead to avoidable panic, especially during heatwaves, power outages, or while traveling . 🚫 The Myth: "Insulin must always stay refrigerated" Many believe that insulin instantly loses effectiveness once it’s out of the fridge. This is not true — and can cause undue stress, particularly in hot climates like India or during journeys where refrigeration isn’t available. ✅ The Fact: Most insulin types tolerate room temperature According to World Health Organization (WHO) and insulin manufacturer guidelines : 🔹 Opened insulin vials or pens can be safely kept at room temperature (15–25°C / 59–77°F) for up to 28 days. That means: You don’t need to return it to the fridge every time after injection. It's safe fo...

🧴 TREATMENT OF POISONING – A COMPREHENSIVE OVERVIEW

-
By Dr. Sk Sabir Rahaman, MBBS , MD (Pharmacology), DFM(Family Medicine), FCFM, CCEBDM, CCLSD   🧪 Definition & Scope Toxicology : Branch of pharmacology dealing with harmful effects of chemicals on living organisms. Poisoning : Harmful effects caused by ingestion, inhalation, dermal exposure, or injection of toxic substances (drugs, pesticides, household chemicals, industrial agents, venoms). Medico-legal importance : All poisoning cases are medical emergencies. Must be reported to police/authorities (especially suicidal, homicidal, or accidental cases) under Indian law. 🛑 General Principles of Management (ABCDE of Toxicological Emergencies) A – Airway Ensure patency (tongue fall, aspiration common in comatose patients). Place in left lateral position to reduce aspiration. Intubate with cuffed endotracheal tube if airway compromised. Regular suction of secretions. B – Breathing Monitor with pulse oximetry and ABG. Give humidified oxy...

🌿 Rational Use of Medicines (RUM): A Guide for Safer and Smarter Prescribing

-
By Dr. Sk Sabir Rahaman, MBBS , MD (Pharmacology), DFM(Family Medicine), FCFM, CCEBDM, CCLSD   📍 Specialist Family Physician | Consultant Pharmacologist | Lifestyle & Diabetes Expert Medicines save lives, ease suffering, and improve health outcomes. But when they are used irrationally , they can cause more harm than good. The World Health Organization (WHO) emphasizes the importance of the Rational Use of Medicines (RUM) to ensure patient safety, treatment effectiveness, and cost efficiency. In this blog, we’ll explore what RUM means, why it matters, and how healthcare professionals can practice it effectively. 📌 What is Rational Use of Medicines? According to WHO: “Rational use of medicines requires that patients receive medications appropriate to their clinical needs, in doses that meet their individual requirements, for an adequate period of time, and at the lowest cost to them and their community.” In simple words: it’s about prescribing the right medicine, in t...
