Does your blood flow feel constricted? Let's talk about Arterial Insufficiency!

Do you sometimes feel pain in your legs when you walk? Or do you feel dizzy or numb in some places? Don't think that these are just random things. Maybe this is a sign that the blood circulation in your body is a little weak. Today we are going to talk about an equally important topic. That is the decrease in blood circulation in the arteries, or as doctors call it, `(Arterial Insufficiency)`.

What is arterial insufficiency?

Simply put, this is when the amount of blood flowing through one or more arteries in our body decreases. Arteries are like a system of tubes that carry oxygen-rich blood throughout our body from the heart to all other organs and tissues. So, what happens if these tubes become blocked or narrowed? That's when blood flow decreases. The main reason for this is the buildup of fat in the artery walls, a condition called ``Atherosclerosis''.

Every part of our body needs oxygen-rich blood to function. So if the arteries are not able to send blood properly, our organs and tissues will not be able to function properly. This can lead to serious complications .

This condition (Arterial Insufficiency) can affect you in two main ways:

1. Acute arterial insufficiency: This is when blood flow is suddenly reduced or completely stopped due to some reason (often a blood clot). This is a condition that requires emergency medical treatment.

2. Chronic arterial insufficiency: This is a condition where blood flow gradually decreases due to an underlying medical condition (often the aforementioned atherosclerosis). Over time, symptoms gradually worsen, and the risk of complications increases.

The most important thing is that if this condition is recognized early and treated properly, the risk of serious complications can be greatly reduced.

How does this situation affect our bodies?

Reduced blood flow in the arteries reduces blood supply to various parts of our body, especially the major organs and limbs. The way this affects the body depends on which artery is narrowed or blocked .

Think about it this way:

• If the arteries in your neck (carotid or vertebral arteries) become narrowed, for example in a condition called carotid artery disease, it affects your brain .
• A problem with the aorta , such as an abdominal aortic aneurysm, can affect your chest, back, and abdomen .
• If there is a blockage in the coronary arteries that supply blood to the heart , a condition called coronary artery disease, it directly affects your heart .
• If there is a problem with the artery that supplies blood to the small intestine (the ``Superior mesenteric artery``) , a condition like ``Mesenteric artery stenosis``, it can affect the function of your small intestine .
• If there is a problem with the arteries that supply blood to the kidneys (renal arteries) , a condition called renal artery disease, it will affect your kidneys .
• Blockages in the arteries in your legs , such as peripheral artery disease (PAD), can affect your legs and feet .
• A condition called pulmonary embolism, which is a blood clot that blocks the arteries in your lungs , can affect your lungs .

But it's also important to remember that reduced blood flow through the arteries actually affects every part of the body indirectly. You may notice symptoms in the part of the body closest to the most blocked artery. However, the same things that cause the narrowing of the arteries there (such as atherosclerosis) can also happen in arteries elsewhere in the body. For example, if you have chronic reduced blood flow due to atherosclerosis in an artery in your leg, you are at risk for the same thing in your heart.

Every part of our body needs oxygen to survive. If an organ or tissue suddenly loses oxygen, that organ can fail within hours, in a case of `Acute arterial insufficiency`. This can lead to life-threatening emergencies caused by reduced blood flow in the arteries:

• Critical limb ischemia: Blockage of blood flow to the arms , legs, or feet.
• Heart attack: Blockage of blood flow to the heart.
• Pulmonary embolism: Blockage of blood flow to the lungs.
• Stroke: Blockage of blood flow to the brain.

This condition can be fatal if not treated properly, which is why it's so important to be aware of its symptoms and talk to your doctor about your risks.

What is the difference between arterial blood loss and venous blood loss?

Both of these are issues related to blood circulation, but there is a slight difference.

Arterial insufficiency is a problem with blood flow in the arteries. Venous insufficiency is a problem with blood flow in the veins (the vessels that carry impure blood back to the heart).

Simply put:

• Arteries are what carry clean, oxygen-rich blood from the heart throughout the body.
• Veins are what bring oxygen-depleted, impure blood back to the heart.

The causes of both conditions are different. The main cause of reduced blood flow in the arteries is the buildup of fat in the artery walls (atherosclerosis). Reduced blood flow in the veins is mainly caused by damage to the veins in the legs.

Arterial insufficiency can occur in an artery anywhere in the body, but a condition called venous insufficiency mainly affects the legs.

Both of these conditions can cause pain and discomfort in the legs. If your legs are constantly aching, feel heavy, swollen, or tired, be sure to see a doctor to discuss these symptoms.

What are the symptoms of this?

Some people may not have any symptoms until the condition becomes severe or an emergency occurs. However, some people may experience symptoms such as:

• Dizziness: A feeling of losing balance.
• Intermittent claudication: Leg pain that occurs when you walk and subsides when you rest. This is when you experience pain in your leg while doing some activity, especially walking, and the pain goes away after a short rest.
• Pain in the feet or toes: A burning, aching sensation in the feet or toes, even when at rest.
• Changes in skin color and texture: Scaly skin on the legs and feet, itching, and changes in skin color.
• Stomach pain: A stomach ache that starts 15-20 minutes after eating, lasts for a few hours, and then goes away.
• Ulcers: Non-healing sores on the legs and feet (especially the ankles). These are a sign of poor blood circulation.
• Weight loss: Sudden, unplanned weight loss.

You may have narrowed or blocked arteries in more than one place in your body. For example, people with peripheral artery disease (PAD) in the legs are more likely to develop coronary artery disease (CAD). So, you may have a combination of symptoms related to each problem. That's why it's important to tell your doctor as soon as you notice even the slightest symptom.

Symptoms of an emergency - don't ignore these!

If you have any of the following symptoms, call 911 (1990 in Sri Lanka) or go to the nearest hospital immediately. These may be signs of a medical emergency:

• Chest pain or tightness.
• Feeling like you are seeing in two or losing your vision.
• Fainting.
• Tissue death (`Gangrene`) (blackening of the skin, bad smell).
• Pale skin, cold sweats, or blue skin.
• Sudden increase in pulse rate.
• Slurred speech.
• Sudden, severe pain in the chest, arm, shoulder, neck, or jaw.
• Sudden difficulty breathing for no reason.
• Sudden pain or discomfort in the shoulders, neck, stomach, and/or back for no apparent reason.

With some symptoms, you may not even be able to make a call. Therefore, if possible, keep a `medical alert device` (like a necklace) with you at all times. Also, tell your family and friends about these symptoms. So that they can call 1990 for you as soon as they notice them.

Why is this happening? What are the reasons?

The two main reasons for decreased blood flow in the arteries are:

• Atherosclerosis: Fatty deposits in the artery walls (atherosclerosis): Fatty deposits, such as cholesterol, build up inside the artery, narrowing or completely blocking it.
• Thrombosis: A blood clot forms inside an artery, blocking blood flow.

How do you diagnose this?

Doctors diagnose this condition by asking you about your symptoms, taking your medical history, and doing a physical exam. Your doctor will ask you a lot of questions to learn as much as possible about your condition. For example:

• What are your symptoms?
• How long have these symptoms been present?
• Where do you feel the pain?
• Do the symptoms come and go? If so, when do they come?
• What can you do to reduce symptoms?

The doctor will also talk to you about:

• Your previous medical history.
• Diseases that run in your family (genetically related).
• Other medical conditions you currently have.
• The medications you use.

During the physical examination, the doctor may do the following:

• They tell you to smile to see if one side of your face droops.
• Pulses are checked at several points on the body (such as the chest, wrist, and ankle).
• A blood sample is taken to check for various levels that may be related to arterial disease.
• Your eyes and vision will be checked.
• See if there are any changes in your skin color or texture.
• Check for skin ulcers.
• Blood pressure is measured in both arms.

This exam can tell your doctor a lot. However, they may also do some special tests to learn more about your arteries.

Further tests

Here are some tests that can help detect reduced blood flow in arteries in various parts of the body:

• Ankle-brachial index (ABI): This compares the blood pressure in the lower legs with the blood pressure in the arm. This can show how well the blood is flowing in the arteries in the legs.
• CT Angiogram (`Computed tomography angiogram - CTA`): Takes 3D pictures of the arteries that supply blood to the heart (coronary arteries), arms, legs, or intestines to help find blockages.
• Echocardiogram (`Echocardiogram - echo`): Uses sound waves to check the function of the heart.
• E.C.G. (`Electrocardiogram - ECG/EKG`): Records the electrical activity of the heart. Can detect problems with blood flow and irregular heartbeat.
• Pulse volume recording: Measures changes in blood volume in the legs. Can detect blockages.
• Vascular ultrasound: Uses sound waves to take pictures of your arteries (including those in your neck) to look for blockages.

What are the treatments?

Treatment depends on the cause and severity of the condition. Talk to your doctor about the best treatment for you. Some treatment options include:

• Atherectomy (surgery to remove plaque from arteries).
• Surgery to remove blockages in the arteries of the neck (`Carotid endarterectomy`).
• Coronary artery bypass grafting (`Coronary angioplasty`).
• Coronary artery bypass grafting (CABG).
• Lifestyle changes: exercising, eating healthy.
• Medications: Control blood pressure, cholesterol, and blood sugar levels.
• Medicines that reduce the risk of blood clots (Anticoagulants).
• Small mesh tubes (`Stents`) used to keep arteries open.

Who is at higher risk of developing this? (Risk Factors)

Anyone can develop `Arterial insufficiency`. But some people are at higher risk. If you have any of these conditions, you are also at higher risk:

• Irregular heartbeat (`Atrial fibrillation`).
• Diabetes (`Diabetes Mellitus`).
• High cholesterol in the blood (`Hyperlipidemia`).
• High blood pressure (Hypertension).
• Protein C deficiency.
• Protein S deficiency.
• Conditions that cause blood to clot too quickly (`Thrombophilia`).
• Cancer-related blood clots (`Trousseau syndrome`).

Other risk factors:

• Over 60 years of age.
• Pregnancy.
• Smoking and tobacco use.
• Use of birth control pills containing estrogen.

How to protect yourself from this? (Prevention)

Making lifestyle changes can go a long way in reducing this risk. Here are some things you can do:

• Exercise daily. Try to walk for at least 30 minutes a day, five days a week. Be sure to talk to your doctor before starting a new exercise routine.
• Quit smoking and tobacco use completely. This includes vaping and chewing tobacco.
• Follow a heart-healthy diet.
• Limit your alcohol consumption. For men, no more than two drinks a day. For women, no more than one drink a day.
• Control your weight. Ask your doctor what a healthy weight is for you.
• Take the prescribed medication on time.
• Get a medical checkup at least once a year.

How to live with this situation?

When living with arterial insufficiency, keep these things in mind:

• Make an exercise plan. Not everyone is the same. Choose an exercise that you enjoy. It can be anything from dancing, ice skating, to walking in the park. Also, find ways to add a few more steps to your daily routine. Always ask your doctor what exercises are safe for you.
• Look into healthy eating options. Look into things like the Mediterranean diet and the DASH diet.
• Keep your skin clean. This is especially important if you have PAD, diabetes-related neuropathy, or other peripheral neuropathy. Wash your feet and legs daily and apply moisturizer. Check for skin discoloration, cracks, or sores.
• Stop smoking and using tobacco. Ask your doctor for help.
• Wear comfortable shoes. Shoes should be supportive and fit well.

Finally, things to remember

Keep all your doctor appointments and follow-ups. Your doctor will tell you how often you should come back.

Also, if you notice any new symptoms or changes in your symptoms, call your doctor right away. It can also be helpful to print out a list of your symptoms and keep them with you. It's easy to miss a symptom in the hustle and bustle of everyday life, or to wonder "what's this?" So, be aware of the things you need to watch out for. Share this information with your loved ones.

When you find out you have `Arterial insufficiency`, you may wonder, "How am I going to fix this?" That's the first thing we think about when we're sick. You may wish you could turn back time and do things differently. But this is not a time to look back, but to look forward.

Focus on what you have now. What changes can you make right away? What are the most important ones? Get guidance from your doctor about lifestyle changes and treatments. Most importantly, you don't have to go through this journey alone. Your doctor and your entire healthcare team are here to help you improve your artery health.
