Your question: How does diabetes damage small blood vessels?

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.

How does diabetes cause narrowing of blood vessels?

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.

How does diabetes affect your veins?

The high glucose levels in your blood that are caused by diabetes tend to weaken and damage your blood vessels over time, which can lead to inflammation and infections.

Why do diabetics have small veins?

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.

How does diabetes affect the heart and blood vessels?

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 circulatory system?

Circulatory system

Diabetes raises your risk of developing high blood pressure, which puts further strain on your heart. When you have high blood glucose levels, this can contribute to the formation of fatty deposits in blood vessel walls.

How does insulin affect arteries?

Insulin enhances the compliance of conduit arteries, relaxes resistance arterioles to increase tissue blood flow and dilates precapillary arterioles to expand muscle microvascular blood volume. These actions are impaired in the insulin resistant states.

Does sugar damage blood vessels?

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.

Is diabetic blood vessel damage reversible?

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.

Can you reverse diabetes damage?

Nerve damage from diabetes can’t be reversed. This is because the body can’t naturally repair nerve tissues that have been damaged.

Does diabetes cause spider veins?

It’s no coincidence that the first place diabetics often notice spider veins, redness or bluish discoloration, varicose veins or other problems is their feet and legs. This is where your blood supply is farthest from your heart, and your circulatory system has to work the hardest to pump blood back up.

What are the diabetic complications?

  • Cardiovascular disease. …
  • Nerve damage (neuropathy). …
  • Kidney damage (nephropathy). …
  • Eye damage (retinopathy). …

  • Alzheimer’s disease.

What organ is damaged when you have diabetes?

Diabetes affects your heart and your whole circulation. That includes small blood vessels in your kidneys, eyes, and nerves, and the big ones that feed your heart and brain and keep you alive. The damage starts with high blood sugar (glucose) and insulin levels.

At what blood sugar level does damage occur?

“Post-meal blood sugars of 140 mg/dl [milligrams per deciliter] and higher, and fasting blood sugars over 100 mg/dl [can] cause permanent organ damage and cause diabetes to progress,” Ruhl writes.
