Does diabetes affect arteries or veins?

Excess blood sugar decreases the elasticity of blood vessels and causes them to narrow, impeding blood flow. This can lead to a reduced supply of blood and oxygen, increasing the risk of high blood pressure and damage to large and small blood vessels.

Does diabetes affect your arteries?

Over time, high blood sugar can damage blood vessels and the nerves that control your heart. People with diabetes are also more likely to have other conditions that raise the risk for heart disease: High blood pressure increases the force of blood through your arteries and can damage artery walls.

Does diabetes affect the veins?

Uncontrolled Diabetes Makes Varicose Veins Worse

High levels of glucose in the blood has the same effect as it travels through the circulatory system. Uncontrolled levels of blood glucose damage the veins and can delay blood passing through some smaller blood vessels in the legs and feet.

Does diabetes cause arterial or venous insufficiency?

A number of medical conditions are associated with venous disease. Among the more serious of these disorders is diabetes, which can significantly exacerbate the symptoms of varicose veins and other chronic venous insufficiencies.

Does diabetes cause narrowing arteries?

People with diabetes have too much sugar in their blood. This may change blood chemistry and cause blood vessels to narrow. Or, it can damage blood vessels — a process known as atherosclerosis. Atherosclerosis is also called hardening of the arteries.

What problems do the damaged blood vessels in a diabetic cause?

It can cause heart attacks, strokes and prevent oxygen from getting to the legs and feet. When it affects the legs and feet (and sometimes arms) it is called peripheral arterial disease, also known by its initials, PAD. If PAD is not treated, it can lead to gangrene and amputation.

How does diabetes affect the nerve?

Neuropathy is one of the long-term complications of diabetes. Over time, high blood glucose (sugar) levels can damage the small blood vessels that supply the nerves in your body. This stops essential nutrients reaching the nerves. As a result, the nerve fibres can become damaged, and they may disappear.

Why do diabetics have poor veins?

Some people with diabetes develop chronic venous insufficiency (CVI), which increases the risk for varicose veins. In CVI, the tiny one-way valves in the leg veins don’t work properly, which means blood traveling back to the heart from the legs can succumb to gravity and pool in the veins.

Does diabetes thicken blood?

Just like in the heart, the complications here are caused by damaged blood vessels in the kidneys. Over time, high blood sugar harms blood vessels walls and kidney cells, making them thicker and unable to filter your blood.

Can diabetes cause nerve damage?

High blood sugar damages your nerves, and these nerves may stop sending messages to different parts of your body. Nerve damage can cause health problems ranging from mild numbness to pain that makes it hard to do normal activities. Half of all people with diabetes have nerve damage.

Can you reverse diabetic vein damage?

Drugs that were developed to treat Alzheimer’s Disease could be re-purposed to prevent – or even reverse – the damage done to the blood vessels in people who are obese or suffer from type 2 diabetes, according to new research.

Does sugar build plaque in arteries?

As the excess glucose circulates in the blood vessels, it begins to weaken the artery walls, making them leaky and dysfunctional, which can lead to the formation of atherosclerosis.

How does diabetes affect nerves and blood vessels?

Researchers think that over time, uncontrolled high blood sugar damages nerves and interferes with their ability to send signals, leading to diabetic neuropathy. High blood sugar also weakens the walls of the small blood vessels (capillaries) that supply the nerves with oxygen and nutrients.
