It is a term used to describe hardening and narrowing of the arteries due to plaques (buildup of cholesterol, fats, or other unnecessary substances in the artery walls – as noted before). It is a specific kind of arteriosclerosis!
These hardening and narrowing of arteries is the key point for other complications of high cholesterol to occur. Both mild and severe atherosclerosis will restrict blood flow, making your heart work harder. As a result, you’re likely to get tired more easily.

Over time, untreated atherosclerosis will lead to more serious complications such as coronary heart disease, heart attack, stroke, and peripheral artery disease – and feeling exhausted is quite common at early and latter stages of all those conditions.
It seems that high cholesterol indirectly contribute to lead to fatigue in several ways. But remember, if you have feeling exhausted, this doesn’t definitely mean that you have high cholesterol!
Tiredness can be attributed by many factors, which can be classified into the following main categories:
- Physical causes. Not just the well-recognized ones such as heart problems, anemia, or thyroid disease – but also more ailments like sleep apnea (sleeping disorder) and food intolerance. Even being underweight or overweight may contribute to cause fatigue, too.
- Psychological causes. The worries and strains of your daily life can drain your energy a lot, leading to fatigue. Even positive events (such as getting married) can also be exhausting. In fact, tiredness due to psychological events is far more common than physical tiredness.
- Lifestyle causes. Bad diet, sedentary lifestyle, and abusing alcohol – for examples, are some of lifestyle factors that can contribute to cause fatigue.
