Why Is Diabetes A Risk Factor For Stroke?

Why Is Diabetes A Risk Factor For Stroke
What is diabetes stroke risk? – Adults with are 1.5 times more likely to have a stroke than people who don’t have diabetes. And they are almost twice as likely to die from heart disease or stroke as people without diabetes. Diabetes prevents your body from processing food properly. Your body can’t make insulin or can’t use insulin correctly, which causes glucose (sugar) to build up in your blood.

Over time, high glucose levels can damage the body’s blood vessels, increasing the chance of stroke.Many adults with diabetes also have other health problems that can lead to stroke:The symptoms of diabetes-related stroke are the same as the symptoms of any stroke:

Any trouble talking. Dizziness, problems with balance or trouble walking. Severe, sudden headache. Sudden confusion. Trouble seeing or double vision. Weakness or numbness on one side of the body (for example, one side of the face, one arm or one leg).

A stroke is a medical emergency. Get medical attention immediately if you experience any of the symptoms. If you may have had a stroke, a healthcare provider will likely:

Check whether you can move your face muscles, arms and legs. Determine whether you are thinking clearly by asking simple questions or asking you to describe a picture or object. Order tests to take pictures of your brain, such as a or, Use other tests to examine your heart () or blood vessels (ultrasound or arteriogram).

If a stroke or stroke risk is identified early, some treatments can help, such as:

Drugs to break up blood clots. Surgery to place a stent in a blood vessel to open it and increase blood flow (). Surgery to remove fat blocking your arteries ().

If you have a stroke and have long-lasting effects from it, may include:

Occupational therapy to relearn how to do important daily tasks, such as writing and getting dressed. Physical therapy to regain strength and function in your arms and legs. Psychological counseling to cope with any mental health issues caused by stroke. Speech therapy to learn how to talk better if stroke affected your speech.

If you have diabetes, certain lifestyle changes can help you lower your chance of stroke:

Check your blood glucose level often and take steps to keep it within a healthy range (less than 140 mg/dL). Check your blood pressure regularly and report problems to your healthcare team. Eat a nutritious, balanced diet to lower and maintain a healthy weight. Exercise regularly. Get enough sleep to maintain health and energy. Keep all of your medical appointments. Limit salt in your diet to help regulate blood pressure. Maintain a weight that’s healthy for you and lose belly fat. and/or using tobacco products. Take all of your medications exactly as prescribed.

The outlook after stroke varies a lot from person to person. Depending on the type of stroke and its effects, recovery can take weeks to years. Some people have minor strokes and don’t experience any effects. Others have major strokes and lifelong disabilities.

Any trouble talking. Dizziness, problems with balance or trouble walking. Severe, sudden headache. Sudden confusion. Trouble seeing or double vision. Weakness or numbness on one side of the body (for example, one side of the face, one arm or one leg).

A note from Cleveland Clinic People with diabetes have a higher chance of stroke, which can cause serious health problems and disabilities. But you can reduce your risk of stroke if you monitor and regulate your blood glucose, blood pressure, cholesterol and weight.

Does diabetes double the risk of stroke?

What you Should Know about Diabetes – Diabetes, also called diabetes mellitus, is a condition that causes blood sugar to rise. A fasting blood glucose (sugar) level of 126 milligrams per deciliter (mg/dL) or higher is dangerous. People who have diabetes are 2 times as likely to have a stroke compared to people who do not have diabetes.

Why is diabetes a risk factor?

Complications – Type 2 diabetes affects many major organs, including your heart, blood vessels, nerves, eyes and kidneys. Also, factors that increase the risk of diabetes are risk factors for other serious chronic diseases. Managing diabetes and controlling your blood sugar can lower your risk for these complications or coexisting conditions (comorbidities).

Heart and blood vessel disease. Diabetes is associated with an increased risk of heart disease, stroke, high blood pressure and narrowing of blood vessels (atherosclerosis). Nerve damage (neuropathy) in limbs. High blood sugar over time can damage or destroy nerves, resulting in tingling, numbness, burning, pain or eventual loss of feeling that usually begins at the tips of the toes or fingers and gradually spreads upward. Other nerve damage. Damage to nerves of the heart can contribute to irregular heart rhythms. Nerve damage in the digestive system can cause problems with nausea, vomiting, diarrhea or constipation. For men, nerve damage may cause erectile dysfunction. Kidney disease. Diabetes may lead to chronic kidney disease or irreversible end-stage kidney disease, which may require dialysis or a kidney transplant. Eye damage. Diabetes increases the risk of serious eye diseases, such as cataracts and glaucoma, and may damage the blood vessels of the retina, potentially leading to blindness. Skin conditions. Diabetes may leave you more susceptible to skin problems, including bacterial and fungal infections. Slow healing. Left untreated, cuts and blisters can become serious infections, which may heal poorly. Severe damage might require toe, foot or leg amputation. Hearing impairment. Hearing problems are more common in people with diabetes. Sleep apnea. Obstructive sleep apnea is common in people living with type 2 diabetes. Obesity may be the main contributing factor to both conditions. It’s not clear whether treating sleep apnea improves blood sugar control. Dementia. Type 2 diabetes seems to increase the risk of Alzheimer’s disease and other disorders that cause dementia. Poor control of blood sugar levels is linked to more-rapid decline in memory and other thinking skills.

How does diabetes affect the risk of heart disease and stroke?

Adults with diabetes are twice as likely to have heart disease or a stroke as people who do not have diabetes. Over time, high blood sugar from diabetes can damage blood vessels in the heart and block blood vessels leading to the brain, causing a stroke. More than 2 in 3 people with diabetes have high blood pressure.

Risk for stroke is actually higher in the young population with diabetes. According to data from the Greater Cincinnati/Northern Kentucky stroke study, diabetes increases ischemic stroke incidence in all age groups, but this risk is most striking before the age of 55 years in African Americans and before the age of 65 years in Whites.6 Individuals with diabetes are more likely to suffer from hypertension, myocardial infarction (MI) and high cholesterol than individuals without diabetes.

Does diabetes affect the brain?

The Connection Between Diabetes and the Brain – Your brain is your body’s command center. It’s made up of nerve cells that keep your body functioning—even while you sleep. It also controls how you feel, learn, and remember. And in order to do all this work, your brain uses sugar in your blood for energy.

The brain is the most energy-demanding organ—needing half of all the sugar energy in the body to function properly. If your blood sugar levels fall outside of your normal range, it can throw your command center off balance. In the same way that diabetes can cause nerve damage to your eyes, feet, and hands, it can also affect your brain by damaging nerves and blood vessels.

This can lead to problems with memory and learning, mood shifts, weight gain, hormonal changes, and over time, other serious problems like Alzheimer’s disease, Since both high and low blood sugar levels can cause these harms, it’s especially important for people with diabetes to keep their blood sugar at target levels.

What are the three main causes of strokes?

Stroke: Key points –

A stroke happens when blood flow to your brain is stopped. It is an emergency situation. It can be caused by a narrowed blood vessel, bleeding, or a clot that blocks blood flow. Symptoms can happen suddenly. If someone is showing any sign of a stroke, call 911 immediately. You have a better chance of recovering from a stroke if emergency treatment is started right away. How a stroke affects you depends on where the stroke occurs in your brain, and on how much your brain is damaged.

Why Is Diabetes A Risk Factor For Stroke

Research shows that approximately one out of four Americans does not realize that they have diabetes. For this reason, it is often referred to as a “silent” disease. Diabetes increases the level of glucose, or sugar, in the blood to dangerous levels and can occur in one of two forms: Type 1 which is genetic, or Type 2 which is largely due to poor diet and unhealthy eating habits.

If left untreated, diabetes can have a negative impact on blood vessels and circulation and lead to serious conditions like atherosclerosis, PAD (peripheral artery disease), and even stroke or heart attack. How does diabetes affect blood vessels? Higher levels of glucose in the blood can cause plaque to build up in arteries, making it difficult for blood to efficiently pump through the arteries and reach areas like the eyes, legs, feet, and kidneys.

This plaque build-up, or hardening of the arteries, is known as atherosclerosis, When these blockages develop in arteries or blood vessels supporting the legs and feet it is known as PAD. “PAD is extremely common in diabetics,” says CTVS board-certified vascular surgeon Dr.

Nicolas Zea, “Untreated PAD can cause serious ulcers or non-healing wounds on the legs or feet, infection or gangrene, and unfortunately even loss of limbs.” Dr. Zea reassures patients that there are many treatment options to effectively manage glucose levels and diabetic complications like PAD, but it is important to recognize risk factors for the disease first so that you are aware if you have it.

What are risk factors or warning signs of diabetes? Since blood sugar levels (via the HbA1c test) are not routinely administered at regular check-ups, Dr. Zea and our team of vascular specialists recommend getting screened for diabetes if you experience or meet the following criteria:

  1. Excessive thirst, frequent urination, sudden weight loss, or extreme fatigue or irritability
  2. Wounds on the legs or feet that are slow to heal or never heal at all
  3. You are of Native American, African American, or Asian American descent.
  4. You are a smoker

CTVS offers the following therapeutic options to treat diabetic complications such as PAD and prevent limb loss/amputation :

  • Medical therapy: CTVS works with various healthcare providers to coordinate medication management and offer counseling for tobacco cessation and exercise therapy.
  • Arteriogram: a minimally-invasive procedure to restore blood flow to legs and feet performed in our Vascular Interventional Suite, keeping patients out of the hospital.
  • Surgical revascularization: bypass surgery performed in the legs to open up arteries and blood vessels when less invasive options are not feasible.
  • Wound care: CTVS works with podiatrists and other wound care specialists to promote wound healing and preserve tissue.
