How Diabetes Affects the Body?

Diabetes is a long-lasting health condition that affects how your body turns food into energy. Your body breaks down most of the food you eat into sugar (glucose) and releases it into your bloodstream.

When your blood sugar increases, it signals your pancreas to release insulin. Insulin is key to letting the blood sugar into your body’s cells for use as energy. With diabetes, your body doesn’t make enough insulin or can’t use it as well as it should.

Too much blood sugar stays in your bloodstream when there isn’t enough insulin or cells stop responding to insulin. Over time, that can cause serious health problems like heart disease, vision loss, and kidney disease.

Potential Risks from Diabetes

This disease affects millions of people in the United States and is a major cause of heart disease, kidney failure, blindness, and amputations. Diabetes can profoundly impact various parts of the body, including the eyes, feet, nerves, skin, heart, and kidneys.

Let’s look closely at how diabetes affects the body and what you can do to help manage the disease.

1.    Eyes:

People with diabetes are at a higher risk of developing eye problems, including diabetic retinopathy, cataracts, and glaucoma. Diabetic retinopathy is a condition that damages the blood vessels in the retina, which can lead to vision loss or blindness.

Cataracts are cloudy areas in the eye’s lens that can cause blurred vision. Glaucoma is a condition that increases pressure in the eye and can damage the optic nerve, leading to vision loss or blindness.

2.    Feet:

Diabetes can also affect the feet, causing various problems, including diabetic neuropathy and nerve damage that can cause numbness, pain, and tingling.

It can make it difficult for people with diabetes to feel cuts, blisters, or other foot injuries, leading to infections and other complications. In severe cases, amputations may be necessary.

Potential Risks from Diabetes

3.    Nerves:

Diabetes can also cause diabetic neuropathy, which affects the nerves and can lead to pain, tingling, and loss of sensation. It can also affect the autonomic nerves that control the heart, bladder, and digestive system, leading to problems such as heart disease, incontinence, and digestive issues.

4.    Skin:

People with diabetes are more prone to skin problems, such as infections and skin conditions. High blood sugar levels can also cause the skin to become dry, itchy, and prone to infections.

5.    Heart:

People with diabetes are at a higher risk of developing heart disease, a leading cause of death among people with diabetes. High blood sugar levels can damage blood vessels and make it more difficult for the heart to pump blood throughout the body. It can increase the risk of heart attacks and stroke.

6.    Kidneys:

Diabetes can also affect the kidneys, leading to diabetic nephropathy, which is damage to the blood vessels in the kidneys. It can lead to a decrease in kidney function and, in severe cases, kidney failure.
