how Does Vascular Diseases affect blood circulation

The complex network of blood vessels, known as the vascular system, plays a vital role in keeping life going. This  ensures the continuous delivery of oxygen and nutrients to every cell in the body while removing waste products. However various diseases can affect this system, and can cause several complications.

What is blood circulation and what should you understand?

Blood circulation is a process that occurs continuously throughout the body, where the heart acts as pump, keeps moving the blood through a network of arteries, veins, and capillaries. Arteries carry oxygen-rich blood away from the heart to various organs and tissues. Veins, on the other hand, transport oxygen-depleted blood back to the heart for re-oxygenation. The tiniest blood vessels, called capillaries, help the blood and surrounding tissues exchange waste products, nutrients, and oxygen.

What are the common vascular diseases and how do they affect blood circulation?

There are several types of vascular diseases and they can affect blood circulation significantly. Here are the common vascular diseases:


This is the most common form of vascular disease, characterized by the buildup of plaque within the arterial walls. Plaque formation narrows the arteries, restricting blood flow to vital organs. This can lead to various complications including:

Coronary artery disease:

Plaque build up in the coronary arteries supplying blood to the heart can cause chest pain, heart attack and heart failure. Seek medical care from the best vascular surgery hospitals in Coimbatore to restore the quality of life and help blood circulate smoothly.

Peripheral artery disease:

Reduced blood flow to the legs due to narrowed arteries can cause pain, cramping, and difficulty walking. In severe cases, it can lead to tissue death and gangrene.

Carotid artery disease:

Plaque buildup in the carotid arteries supplying blood to the brain can increase the risk of stroke.

Deep vein thrombosis:

This condition involves the formation of blood clots within deep veins, usually in the legs. These clots can stop blood flow entirely or partially, which can result in:

  • Affected limb may show swelling, pain, and tenderness,
  • Changes in skin color
  • Visible redness
  • Increased risk of pulmonary embolism, which is a life threatening condition where a blood clot ruptures and travels to the lungs and eventually blocks the blood circulation


This is a group of autoimmune disorders characterized by inflammation of blood vessels. The inflammation can damage and weaken the vessel walls, leading to:

  • Narrowing or blockage of blood flow
  • Organ damage depending on the affected vessels.
  • Skin rashes, fatigue, and fever


This a bulge or weakening in the wall of an artery. Aneurysms can rupture, causing life-threatening internal bleeding. Depending on the location, they can also block blood flow and damage surrounding tissues.

Raynauld’s disease:

This condition affects the small arteries in the fingers and toes, causing them to narrow in response to cold temperatures or emotional stress. Although this type of vascular disease is quite rare. It can lead to:

  • Tingling and numbness
  • Pain in the affected toes and fingers
  • Skin color changes to white or blue
  • Visible redness

What are the consequences of insufficient blood circulation?

Blood circulation is an important process, it needs to keep processing 24/7 without a break as it helps the organ functioning. Every single function your body performs requires blood circulation and when such an important function is interrupted or stopped it can lead to several consequences. Few major as follows:

Organ damage:

Reduced blood flow can deprive organs and tissues of essential oxygen and nutrients, leading to damage and dysfunction of the organs. This can affect the heart, brain , kidneys, lungs, and other important organs who perform vital functions to keep the body functioning.

Chronic pain:

Inadequate blood flow can cause pain in the affected area of vascular diseases especially in legs and feet. As the vascular diseases commonly occur in the feet and leg area.

Wound healing problems:

Improper blood circulation can decrease the delivery of oxygen and nutrients needed for wound healing, leading to delayed chronic wounds and they further worsen the condition especially diabetic foot ulcers in case you have high levels of unmanaged blood sugar levels or diabetes. Seeking treatment for vascular disease is important to promote wound healing.

Increased risk of infection:

Reduced blood flow can weaken the immune system’s ability to fight off infections.


In severe cases of vascular diseases with poor blood circulation, tissue death or commonly known as gangrene can occur, which risks the chances of limb loss or amputation.

What are the best tips to manage vascular diseases?

Early diagnosis and management of vascular diseases are important to prevent complications and improve blood circulation. Here are the best strategies:

Lifestyle modifications:

Maintaining a healthy lifestyle through a balanced diet, regular exercise, and stress management can significantly reduce the risk of developing vascular diseases and improve overall circulation.


Depending on the specific condition, medications can help lower cholesterol, control blood pressure, prevent blood clots, and manage inflammation.

Important Takeaway:

Blood circulation is an important function of the body, it needs to be performed round the clock without any interruption or pause. Any pause in the blood circulation can have severe complications and overall quality of health can be affected. Consult a vascular disease specialist in Coimbatore if you are facing any symptoms of vascular diseases.
