The risk of having a stroke is two to four times higher in people with type 2 diabetes, 90% of whom are over-weight. Stroke occurs either when a blood vessel ruptures or a blood clot blocks an artery to the brain, causing damage to nerve cells.
2. TYPE 2 DIABETES
people with excess body fat – especially in the abdominal area – often become resistant to insulin, a substance that helps the body store glucose. When glucose levels soar, diabetes results. One side effect is damage to blood vessels in the retina, which can lead to blindness.
3. HEART DISEASE
Obese people tend to have elevated cholesterol, which can lead to plaque buildup in the arteries. They are twice as likely to have hypertension.
4. LIVER DISEASE
Many obese people develop deposits of fat inside the liver, a condition that can progress to cirrhosis in about 10% of cases, and occasionally to liver failure.
5. COLON CANCER
Obese people are at greater risk of colon cancer. Abdominal fat appears to increase risk more than fat elsewhere, which may explain why men (who tend to store fat in their abdomens) have higher risk.
Being overweight places additional strain on the spine, hip, and knee joints, causing a loss of cartilage. As the cartilage deteriorates, joint space narrows and bones grinds together.
