How Does Diabetes Affect the Body?
When your blood sugar stays too high for too long, it causes inflammation and damages your blood vessels. Over time, this affects the function of major organs and systems.
1. Heart and Blood Vessels
- Increases risk of high blood pressure
- Causes hardening of arteries (atherosclerosis)
- Leads to higher chances of heart attack, stroke, and heart failure
2. Eyes
- Damages small blood vessels in the retina (diabetic retinopathy)
- Can cause blurred vision, floaters, and even blindness
- Increases risk of cataracts and glaucoma
3. Kidneys
- High sugar levels make kidneys work harder
- May lead to chronic kidney disease or kidney failure
- Often requires dialysis or a kidney transplant in severe cases
4. Nerves (Neuropathy)
- Numbness, tingling, or pain—especially in hands and feet
- Can lead to digestive issues, sexual problems, or poor balance
- May result in foot injuries going unnoticed
5. Feet
- Poor circulation and numbness raise risk of foot ulcers
- Slow wound healing can lead to infections
- In severe cases, amputation may be needed
6. Skin
- Prone to fungal infections, dry skin, and diabetic dermopathy
- Sores and cuts may take longer to heal
- Increases risk of yeast infections
7. Brain and Mental Function
- Higher risk of stroke
- May cause memory problems or increase risk of dementia
- Can lead to depression or mood changes
8. Hearing
- Nerve and blood vessel damage may cause hearing loss
9. Mouth and Gums
- Higher risk of gum disease (periodontal disease)
- Slower healing of mouth sores or infections
10. Cholesterol and Blood Fats
- Lowers good cholesterol (HDL)
- Raises bad cholesterol (LDL and triglycerides)
- Increases the risk of atherosclerosis
Common Symptoms of Diabetes-Related Body Changes
- Frequent urination
- Increased thirst
- Weight loss
- Fatigue
- Slow-healing wounds
- Blurred vision
