Symptoms Of Clogged Arteries
Clogged arteries are caused by atherosclerosis, which develops over time as plaques formed from fats, minerals, cholesterol, and more build up inside the walls of your arteries. These buildups cause the inner tunnels, called lumens, of the arteries to become smaller and narrower.
As a result, the heart has to use more pressure to pump blood through smaller vessels. This increases blood pressure and puts strain on the pumping ability of the heart.
You may also notice that different parts of your body begin to suffer from a reduced supply of oxygenated blood, especially if the artery becomes completely clogged. Your symptoms depend on where the blockage occurs and what part of your body receives a reduced blood supply.
Symptoms of blocked or clogged arteries can include:
- Weakness, especially on one side of the body
- Loss of consciousness
Mechanisms Of Vascular Complications In Diabetes And The Impact Of Hypertension
A number of interacting mechanisms are in play as summarized in the following sections .
Putative mechanisms whereby diabetes and hypertension cause vascular disease. Immune cell activation and inflammation are mediated through oxidative stress. AGEs, advanced glycation end products RAAS, renin-angiotensin-aldosterone system RAGE, receptor AGE.
What Are The Symptoms Of High Blood Pressure
Often, people with high blood pressure do not have noticeable symptoms. If the blood pressure is greatly elevated, a person may experience the following. However, each individual may experience symptoms differently. Symptoms may include:
The symptoms of high blood pressure may resemble other medical conditions or problems. Always consult your doctor for a diagnosis.

Severe Low Blood Sugar
As your low blood sugar gets worse, you may experience more serious symptoms, including:
- Having difficulty walking or seeing clearly.
- Acting strange or feeling confused.
- Having seizures.
Severe low blood sugar is below 54 mg/dL. Blood sugar this low may make you faint . Often, youll need someone to help you treat severe low blood sugar.
People with diabetes may experience low blood sugar as often as once or twice a week, even when managing their blood sugar closely. Knowing how to identify and treat it is important for your health. Learn how to treat low blood sugar.
What Is Low Blood Pressure
Blood pressure is recorded as a top number and a bottom number . The top number is the systolic pressure when the ventricles of your heart push the blood out against the walls of the arteries as the blood courses through your body, and the lower number is the diastolic pressure, which is the pressure between your heart beats , when the blood travels through your hearts coronary blood vessels. Normal blood pressure is less than 120 mmHg over less than 80 mmHg. Low blood pressure, which is given the medical term hypotension, is technically a top number of less than 90 mmHg or a bottom number of less than 60 mmHg.

Digestive Endocrine And Circulatory Systems
After you eat, your digestive system breaks down carbohydrates and turns them into glucose. Essentially, glucose is your bodys fuel source.
As your sugar levels rise, your pancreas releases a hormone called insulin, which helps glucose get taken up and used by cells throughout your body. If you have insulin-dependent diabetes, you must take the right about of insulin to get the job done.
Any excess glucose goes to your liver for storage.
When you go a few hours without eating, blood sugar levels go down. If you have a healthy pancreas, it releases a hormone called glucagon to make up for the absence of food. This hormone tells your liver to process the stored sugars and release them into your bloodstream.
If everything works as it should, your blood sugar levels should remain in the normal range until your next meal.
Insufficient blood sugar levels can cause a rapid heartbeat and heart palpitations. However, even if you have diabetes, you may not always have obvious symptoms of low blood sugar. This is a potentially dangerous condition called hypoglycemia unawareness. It happens when you experience low blood sugar so often that it changes your bodys response to it.
Normally, low blood sugar causes your body to release stress hormones, such as epinephrine. Epinephrine is responsible for those early warning signs, like hunger and shakiness.
What Is Hyperglycemia And What Causes Hyperglycemia
Hyperglycemia is defined as high blood glucose levels. This develops when the body has far too much sugar in the blood and hence does not produce enough insulin to disperse the necessary quantity of glucose in the blood.
Many diabetics suffer from hyperglycemia. It happens when a person with diabetes of type 1 is unable to create enough insulin via the pancreas. Because the body may be resistant to insulin, a person with type 2 diabetes isnt producing enough natural insulin to maintain a normal glucose level. This is one of the contributing factors for diabetes dizziness.
If left untreated, hyperglycemia can lead to a variety of complications. Among the potential complications are:
- Blood vessel damage

Causes Of Low Blood Glucose
Low blood glucose is common for people with type 1 diabetes and can occur in people with type 2 diabetes taking insulin or certain medications. The average person with type 1 diabetes may experience up to two episodes of mild low blood glucose each week, and thats only counting episodes with symptoms. If you add in lows without symptoms and the ones that happen overnight, the number would likely be higher.

Hypoglycemia As A Potential Risk Factor For Sudden Death In Diabetes
Cumulating clinical and experimental evidence has shown that hypoglycemia can cause abnormal electrical activity in the heart and has strengthened the premise that hypoglycemia can provoke sudden death. High-resolution electrocardiography, which measures the QT interval precisely, in conjunction with hypoglycemic clamps to control the depth of hypoglycemia, has demonstrated lengthening of the QT interval both in diabetic and nondiabetic individuals . Clinical episodes of hypoglycemia have been shown to cause QT lengthening, measured using ambulatory ECG monitoring and simultaneous measurement of blood glucose .
Activation of the sympathoadrenal system probably drives these changes. Epinephrine infusion increases QT intervals , and -blocking drugs attenuate QT lengthening during experimental hypoglycemia . However, hypoglycemia induces a fall in serum potassium via sympathoadrenal activation and a direct effect of insulin, and hypoglycemia per se may have an effect by directly inhibiting cardiac ion channels that are responsible for potassium efflux during cardiac repolarization .

What Puts People With Diabetes At A Higher Risk Of Bouts Of Low Blood Pressure
Diabetes and age-related changes can result in damage to your nerves involved in monitoring blood pressure as well as your reflexes that help constrict blood vessels and increase heart rate to compensate for standing up or eating a meal. Your nerve sensors in your arteries that monitor blood pressure may not work as effectively if you have diabetes especially if you have poor blood sugar control making them more prone to a drastic drop in blood pressure.

Early Signs And Symptoms Of Type 2 Diabetes
Type 2 diabetes is a disease in which your body doesnât make enough of a hormone called insulin or doesnât use insulin the way it should. Insulin helps carry glucose to your cells. So when thereâs a problem with the insulin, glucose builds up in your blood. Youâve probably heard this called high blood sugar.
About 90% of people who have diabetes have type 2. The other two main ones are type 1, in which your body stops making insulin, and gestational, which happens in pregnant women.
You can usually control type 2 diabetes with lifestyle changes. Some people also need medication.
You might not know that you have type 2 diabetes until it affects your health. About 1 in 4 people with the condition donât know that they have it.
Symptoms can come on slowly. They may include:
What Is A Pulmonary Hypertension
Abnormally elevated pressure in the pulmonary circulation is referred to as pulmonary hypertension. This condition affects the arteries in the lungs and the right side of the heart.
Pulmonary Hypertension Causes
Pulmonary hypertension is caused by changes in the cells that line the pulmonary arteries. These changes cause the walls of the arteries to become stiff and thick, extra tissue may also form. This can reduce or block blood flow through the blood vessels. Increased blood pressure is then caused because it is harder for blood to flow. Pulmonary hypertension can be an associated condition with scleroderma, sarcoidosis, pulmonary embolism, and dermatomyositis.
Pulmonary Hypertension Symptoms
Symptoms of pulmonary hypertension may not present themselves for months or years. Later on, symptoms become worse. Symptoms of pulmonary hypertension may include:

Diabetes Vasoprotection And Potential New Therapies
Data from landmark clinical trials in T2D including UKPDS, ADVANCE, and Action to Control Cardiovascular Risk in Diabetes demonstrate that treating comorbidities including hypertension and hypercholesterolemia is a more effective strategy for reducing cardiovascular complications than targeting blood glucose levels with conventional agents.109 Antihypertensive drugs such as angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, mineralocorticoid-receptor blockers, and calcium-channel blockers may have direct vasoprotective effects, and their use may contribute, at least in part, to reduced vascular complications in patients with diabetes and concomitant hypertension.110 Tight control of BP has been shown to reduce cardiovascular risk in T2D: most recent US and Canadian guidelines recommend a target of < 130/80 mm Hg.111, 112 Statin drugs and clopidrogel are also vasoprotective and may have extra benefit in patients with diabetes. Some of the beneficial effects of these drugs have been attributed to their antioxidant and anti-inflammatory properties.

What Are The Symptoms Of Hyperglycemia
Its especially important to know the early signs of hyperglycemia if you have type 1 diabetes. If hyperglycemia is left untreated in people with type 1 diabetes, it can develop into ketoacidosis, where ketones, which are toxic acids, build up in the blood. This condition is an emergency situation that can lead to coma or death.
Early symptoms of hyperglycemia include:
- High blood sugar.
- Unusual fruity smell on the breath.
- Deep labored breathing or hyperventilation.
- Rapid heartbeat.

Nighttime Low Blood Sugar
While low blood sugar can happen at any time during the day, some people may experience low blood sugar while they sleep. Reasons this may happen include:
- Having an active day.
- Being physically active close to bedtime.
- Taking too much insulin.
- Drinking alcohol at night.
Eating regular meals and not skipping them can help you avoid nighttime low blood sugar. Eating when you drink alcohol can also help. If you think youre at risk for low blood sugar overnight, have a snack before bed.
You may wake up when you have low blood sugar, but you shouldnt rely on that. A continuous glucose monitor can alert you with an alarm if your blood sugar gets low while youre sleeping.
What Are The Symptoms Of Low Blood Pressure
Low blood pressure often has no symptoms, but can sometimes mean that not enough blood is flowing to your brain or organs. This can cause symptoms such as:
- feeling dizzy, faint or light-headed
- feeling unsteady
- suddenly noticing your heartbeat
If you have these symptoms, stop what youre doing and sit down or lie down in case you fall, and drink some water.
Speak to your doctor or nurse if you experience these symptoms. As well as being unpleasant, they could mean youre at risk of having a fall. They could also be a sign of another health problem.

What Not To Do If You Have A Nosebleed
Stopping a nosebleed isnt fun, but it also isnt that difficult. There are, however, certain things you should avoid if you have a nosebleed. Some actions can make the bleeding worse or lead to complications.
You should avoid the following mistakes:
- Dont stop applying pressure for at least 10 minutes. Its tempting to check to see if the bleeding has ended, but each time you release pressure, you could be allowing the blood to start flowing again.
- Dont lay down on your back. Staying upright will reduce the pressure in your nose and will help it to stop bleeding so freely.
- Dont pack your nose with tissues or other items. You can use a tissue to catch the blood. But, picking your nose can cause further damage to your blood vessels and make the bleeding worse.

Causes And Risk Factors Of High Blood Pressure
For most people, theres no single cause of high blood pressure. But we know some things can make you more at risk. These are called risk factors, and one of these is having diabetes.
High levels of sugar in your blood can lead to something called atherosclerosis. This is when theres a build-up of fatty material inside your blood vessels, narrowing them. The narrower the blood vessels, the more the pressure builds up.
The more stress your blood vessels are under, the harder it is to push blood around the important areas of your body. This means your feet, eyes and heart are seriously at risk.
There are other risk factors you cant do much about:
- a family history of high blood pressure
- if your ethnic background is African-Caribbean or Black African
And there are risk factors you do have control over:
- too much salt in your diet
- being overweight
