| Function | What it does | Why it matters |
|----------|--------------|----------------|
| **Pumping blood** | Contracts (systole) and relaxes (diastole) to move blood through the circulatory system. | Delivers oxygen, nutrients, hormones, and removes waste products to every cell. |
| **Maintaining blood pressure** | Generates enough force to keep blood moving against resistance in arteries and capillaries. | Keeps tissues perfused and prevents blood from pooling or collapsing. |
| **Regulating blood flow** | Adjusts stroke volume and heart rate in response to body demands (exercise, rest, stress). | Matches oxygen delivery to metabolic needs and maintains homeostasis. |

Together, these functions keep the body’s cells supplied, waste‑free, and operating at the right pressure and flow.<|return|>

The two most common types are type 1 and type 2, but there are other forms (gestational, monogenic, etc.). Below is a concise overview of the main symptoms, causes, and some additional context.

## 1. Symptoms

| Symptom | Typical Onset | Why It Happens |
|---------|---------------|----------------|
| **Polyuria** (frequent urination) | Early | Kidneys excrete excess glucose, pulling water out of the body. |
| **Polydipsia** (excessive thirst) | Early | Dehydration from fluid loss triggers thirst. |
| **Polyphagia** (increased hunger) | Early | Cells can’t use glucose, so the body signals for more food. |
| **Weight loss** (especially in type 1) | Early | Body breaks down fat and muscle for energy. |
| **Fatigue / weakness** | Early | Energy isn’t being efficiently used. |
| **Blurred vision** | Early‑mid | High glucose causes fluid shifts in the eye lens. |
| **Slow‑healing cuts or infections** | Mid‑to‑late | Poor circulation and immune function. |
| **Numbness or tingling in hands/feet** | Late | Chronic hyperglycemia damages nerves (diabetic neuropathy). |
| **Red, swollen, or painful gums** | Late | Diabetes worsens gum disease. |
| **Recurrent infections** (urinary, skin, vaginal) | Late | High glucose fuels bacterial growth. |
| **Darkened skin patches (acanthosis nigricans)** | Late | Often seen in insulin resistance. |

> **Note:** Many people with type 2 diabetes are asymptomatic for years; routine screening is essential, especially if risk factors are present.

## 2. Causes

### A. Type 1 Diabetes (T1D)

| Factor | Explanation |
|--------|-------------|
| **Autoimmune destruction of β‑cells** | The immune system mistakenly attacks insulin‑producing cells in the pancreas. |
| **Genetic predisposition** | Certain HLA genes (e.g., HLA‑DR3/DR4) increase risk. |
| **Environmental triggers** | Viral infections (e.g., enteroviruses), early exposure to cow’s milk,
