High Cholesterol
Overview
High cholesterol is a common condition where there is an excess of cholesterol in your blood. If you have it, it may not cause symptoms, but it is important to take it seriously because it can increase your risk of heart disease and stroke over time.
Cholesterol is a fatty substance that your body needs in small amounts. However, when levels become too high, it can begin to build up in your blood vessels. Over time, this build-up can narrow the arteries and reduce blood flow to important organs such as your heart and brain.
You may feel completely well and still have high cholesterol. Without regular checks, it can go unnoticed. The good news is that it can be detected easily and managed effectively with lifestyle changes and, when needed, medication.
Symptoms
High cholesterol usually does not cause noticeable symptoms.
- You may not feel any different, even when levels are high. In many cases, it is only discovered during routine blood tests or when investigating other conditions.
Because there are no clear warning signs, regular screening is important, especially if you have risk factors.
