Diabetes and Glaucoma: A New Perspective
A study at the University of Michigan found people with diabetes have a 35% higher chance of having Glaucoma than people who do not. The study went on to say the reason for the higher rates of glaucoma in diabetics is “unknown.” My purpose for writing this article is to explain the nutritional reasons that diabetes and glaucoma often go hand in hand.
Before going further, let me state this very clearly: The purpose of this article is to provide education. Both diabetes and glaucoma are serious conditions requiring medical intervention. All eye conditions must be diagnosed and treated by an ophthalmologist. It is imperative that everyone with diabetes have an eye exam including a retinal exam and a glaucoma screening once yearly at a minimum. Never change your medication dosage without consulting your MD and/or ophthalmologist. If you wish to reduce the amount of glaucoma medication you take, consult with your ophthalmologist. Ask him or her to check your ocular pressure every three months, adjusting your dosage as needed. Failure to work with your ophthalmologist could result in blindness. Please do not take matters into your own hands. None of these statements were evaluated by the FDA and none are intended to diagnose, cure, prevent or treat any health condition.
I was diagnosed with glaucoma in April of 2000. I reversed my glaucoma in less than six months using simple lifestyle changes and it has never returned. (I know it has not returned because I continue receiving ophthalmologic care on a yearly basis.) As someone who has had diabetes for over 45 years, I have dedicated my life to researching the biochemical effects of diabetes and to helping those who have it avoid complications. My research led me to draw distinct conclusions about why diabetics are more likely to have glaucoma.
In the simplest terms, glaucoma is an increase in the internal pressure of the eye. (This is known as the prettyeye 300x225 Diabetes and Glaucoma: A New Perspective“intraocular pressure.”) In the most common form of Glaucoma, Open Angle Glaucoma, the increase in intraocular pressure often occurs because the eye’s drainage system, the trabecular meshwork, fails to drain excess fluid from the eye. This creates increased pressure within the eye. Left untreated, the increased pressure harms the ocular nerve, causing loss of peripheral vision in the early stages and blindness as the disease advances. Glaucoma typically has no symptoms. Those who have it rarely notice its effects until it progresses to the point it harms vision.
Why do diabetics have such high rates of glaucoma? Some suspect it’s due to peripheral nerve and vessel damage caused by high glucose levels. This may be true, but if we dig into the chemistry of diabetes – and insulin – a much simpler cause comes to light. Glucose has a very similar molecular structure to Vitamin C. When cells become resistant to and stop absorbing insulin, they therefore also may stop absorbing vitamin C. (Insulin resistance occurs in Type 2 Diabetes due to excess insulin produced by the body; and in Type 1 Diabetes due to the need to inject high amounts of insulin.) What is one of the first effects of a Vitamin C deficiency? Increased interocular pressure. (For more information on insulin, read: Surprising Facts About Insulin.)
Other deficiencies known to contribute to increased intraocular pressure include deficiencies in vitamin B12, magnesium, zinc, iron and others. All of these deficiencies are very common in people with diabetes. The fact that nutritional deficiencies contribute to or may cause glaucoma cannot be denied. Scientists in Russia have known this for years and very successfully treat glaucoma using a much different protocol than what is used in the US. Quite frankly, the US is one of few countries where glaucoma is treated purely with prescription medications. Other countries combine prescription medications with nutritional support.
Multiple studies showed taking oral Vitamin C reduces interocular pressure by as much as 30% within half an hour. In spite of this being a known fact, very few ophthalmologists tell their patients to take a Vitamin C supplement. For many patients, taking 500 – 2000 mg of Vitamin C on a daily basis reduces their interocular pressure to the point they no longer need prescription medication. One study found Vitamin C was very effective at reducing eye pressure even for patients who did not respond to prescription medication.
So can we reduce ocular pressure simply by taking Vitamin C? In part, yes; however, additional change must occur to allow the body’s cells to adequately absorb the Vitamin C. A key factor to allowing the body’s cells to absorb Vitamin C is to reduce the amount of insulin needed (or being produced by the body) and to improve the cells’ insulin sensitivity. This is typically accomplished by eating a low-carbohydrate diet, eating high amounts of antioxidant-rich foods on a daily basis, and other lifestyle changes.
I recommend taking oral vitamin C throughout the process of improving insulin sensitivity and reducing insulin levels. Some people use vitamin C eye drops to bypass the digestive tract and get the vitamin C directly to the eye tissues, while others use intravenous vitamin C to deliver it directly to the blood stream. Although all three delivery methods are known to be effective, taking vitamin C orally is certainly the most convenient.
Vitamin C is known to benefit diabetics in a variety of ways. In addition to aiding glaucoma, the antioxidant effects of vitamin C are known to help prevent cataracts by preventing the formation of compounds that can lodge in the lens of the eye. Vitamin C is also known to be beneficial for diabetic retinopathy and other diabetic complications. Vitamin C has also been shown to be effective at helping reduce high blood pressure when used in conjunction with other lifestyle changes. The use of vitamin C for both diabetes and glaucoma is beneficial in most cases.
For me personally, the combination of high doses of oral Vitamin C, a strict low-carbohydrate eating style, and high intake of antioxidants quickly restored my intraocular pressure to normal. Since then, I continue eating limited amounts of carbs and still eat high amounts of vegetables, but reducing the amount of insulin I take on a daily basis seems to have been the key to permanently reducing my intraocular pressure. Reducing the amount of insulin I need on a daily basis allowed my cells to absorb Vitamin C and naturally decreased systemic inflammation. One of the greatest joys of my life is knowing I was able, by God’s grace, to permanently eliminate my need for glaucoma medication.
I’ve had diabetes for over 46 years. I’ve lived on both sides of the “medical fence” and have devoted my life to helping other diabetics and anyone dealing with metabolic disorders. I have helped 100′s of Type 1 and Type 2 diabetics improve their glucose control, reverse their need for medication, lose weight and more. I have higher success rates than other practitioners because I live this on a daily basis. I know I can help you. Please contact me to schedule a consultation.
