What is diabetes?

Diabetes is a situation whereby your body doesn’t use insulin properly. Remember, insulin is a hormone that allows sugar to enter the cells in your body. Therefore, if there’s a problem in your body with insulin, then glucose can accumulate in your bloodstream. This will result in high blood sugar. Also, diabetes is a disease that occurs when your blood glucose is too high. Blood glucose is a primary source of energy, and it comes from the food you eat.

What is a cataract?

A cataract is a dense, cloudy area that forms in the lens of the eye. Initially, cataracts begin when proteins in the eye form clumps that prevent the lens from sending clear images to the retina. Remember, the retina works by converting the light that comes through the lens into signals. It sends the call to the optic nerve, which carries them to the brain. Cataracts are common in older people. According to the National Eye Institute, countless people in the US have cataracts. The only means of overcoming this eye problem is to go for cataract surgery. However, you might be wondering how to know if you have a cataract. Below here are the symptoms of cataracts;

  • Blurry vision. This is a situation whereby things start to look dim or blurry. However, if you notice this sign, you don’t need to buy new glasses. You need to see your eye doctor examine you and tell you the next thing to do. Of course, you might need cataract surgery.

What are the connections between diabetes and cataract? 

The only connection between diabetes and cataracts is blood sugar. To better understand this link, it is expedient for you to know how blood sugar can affect the body. If blood sugar is left unchecked, it will slowly damage the blood vessels throughout the body. So, this may include tiny blood vessels in the eyes. Therefore, when diabetes affects these blood vessels, there’s a high risk of cataracts and other eye conditions. Also, if there is a high sugar level in the aqueous humor, it will lead to cataracts. And there’s no how one can come out of it except a cataract surgery is done. Don’t forget that aqueous humor is the space between the eyeballs and the lens of the cornea. Therefore, when there is an increase in blood sugar, the lens will swell, resulting in blurry vision. Furthermore, uncontrolled blood sugar can cause enzymes in the lens to convert glucose to a substance called sorbitol. Of course, if there’s too much sorbitol in the lens, it can lead to cloudy vision.

How can diabetes lead to cataracts?

Therefore, when one cannot control their glucose levels, the sugar level can rise, causing the lens to swell, which can lead to a cataract. Also, it is expedient for you to know that high blood sugar can lead to problems like blurry vision, cataracts, glaucoma, and retinopathy. Research has shown that diabetes is the primary cause of blindness in adults between twenty to seventy-four.  Click here to read about Weight Training Routines.

Some medications might cause you to bleed during the cataract surgery or interfere with the outcome. Before the cataract surgery commences, it is best to let your doctor know what kind of medication you have been using so that he can also attempt to treat other symptoms of severe eye conditions.

Instead, you can wear flat shoes with non-slip treading. You don’t need a clothing item that will make you too heavy or fragile. 

More so, you don’t have to go for cataract surgery without a makeover. Remember, the doctor is going to work on your face, so make it easy for him. Also, you will have to avoid wearing cologne or perfume, aftershave, deodorant, hairspray, and the like to the surgery center. The aim is to keep your eyes clean and dry, ready for surgery.

Aside from eating, it is not ideal for taking any alcoholic beverage such as wine, beer, or liquor before the surgery time.  You need to abstain from anything alcoholic for at least 24 hours before the surgery.
