Overview

Atherosclerosis is a disease in which fatty deposits, made up of cholesterol, fats, and other substances, build up on the inside walls of arteries. These deposits build up over time and form plaques that narrow and harden the arteries, making it harder for blood to flow smoothly. This process can take years, and at first, it may not cause any problems that are easy to see. But as the narrowing worsens, it can cut off blood flow to vital organs such as the heart, brain, and limbs. This can cause serious problems if left untreated.

Symptoms
Atherosclerosis usually doesn't cause symptoms early on. As the disease progresses, symptoms depend on which arteries are affected. If it affects the heart, a person might experience chest pain during physical activity. If it affects the legs, you might feel pain or cramps while walking. In more serious cases, a sudden blockage can happen, which can cause a heart attack or stroke. The condition can go unnoticed for a long time because symptoms often don't show up until later.

Causes
Long-term damage to the inner walls of arteries leads to atherosclerosis. High cholesterol, high blood pressure, smoking, and diabetes are some of the things that can hurt this. A diet that isn't good for you, not getting enough exercise, and long-term stress can also make things worse. Age and family history raise the risk, which means that some people are more likely to get the disease as time goes on. These things let fat build up and slowly narrow the arteries.

Diagnosis
Risk factors and symptoms are usually the first things doctors consider when making a diagnosis. Blood tests are routinely conducted to assess cholesterol and blood sugar levels, two of the most significant indicators of cardiovascular risk. Imaging investigations such as ultrasound may also be performed to evaluate blood flow and identify any underlying abnormalities. In cases where further clarity is required, advanced scans or angiography may be recommended to precisely locate arterial blockages and determine their severity. Regular health check-ups play a vital role in the early detection of these conditions, often identifying risk factors well before symptoms develop, when intervention is most effective.

Treatment
The goal of treatment is to slow or stop the buildup of plaque and prevent complications. Making lifestyle changes is very important. Eating well, exercising regularly, quitting smoking, and keeping your weight in check are all important parts of this. Doctors may give you medicine to lower your cholesterol, keep your blood pressure in check, and lower your risk of blood clots. In more serious cases, surgery or angioplasty may be necessary to restore blood flow. Many people can manage the condition and lower their risk of serious events with regular care.
