Nation-wide awareness about the vast dangers of obesity is at an all-time high.
Shows like “The Biggest Loser” and various health initiatives shine a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.
Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer. Researchers say the link between obesity and deteriorating vision is the "risk factor that no one talks about". Many health professionals found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness:
- Age-related macular degeneration (AMD)
- Diabetic retinopathy
These health research professionals said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the ophthalmic risks of obesity which can help motivate people to shed those extra pounds.
How Obesity Contributes to Eye Disease
Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusions, thyroid-related eye diseases, and stroke-related vision loss.
The connection between obesity and these eye diseases is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.
Your eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they're extremely thin and small — as thin as ½ the width of a human hair!
Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.
A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease
Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.
An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in green leafy and dark orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases.
The Doctors at Advanced Eyecare can Help Keep Your Eyes Healthy
While a healthy diet and regular exercise greatly increase your chances of living a disease-free long life, they alone are not enough to ensure long term healthy eyesight. Regular eye exams can help prevent or detect the onset of ocular disease, and maintain vision that is clear and comfortable.
