Overview
Combined hyperlipidemia, also known as familial combined hyperlipidemia (FCH or FCHL) or mixed hyperlipidemia, is a condition where the blood contains too much of more than one type of fat (lipid). Specifically, people with this condition have high levels of cholesterol, triglycerides, or both circulating in their bloodstream. The term 'combined' refers to this mix of elevated fats. It is worth noting that this Orphanet entry is marked as 'obsolete,' meaning it has been reorganized into more specific diagnostic categories in current medical classification systems. This condition affects the way the body processes and clears fats after they are absorbed from food or made by the liver. Over time, these excess fats can build up inside blood vessel walls, making them narrower and harder. This raises the risk of serious heart and blood vessel problems, including heart attack and stroke. Common symptoms can be subtle at first. Many people feel no symptoms at all until a complication occurs. Some people develop fatty deposits under the skin or around the eyes (called xanthomas or xanthelasmas). The most important long-term risks are cardiovascular disease, including coronary artery disease. Treatment focuses on lifestyle changes such as a heart-healthy diet and regular exercise, combined with cholesterol-lowering medications when needed.
