Can High Cholesterol Make You Tired?

Introduction to High Cholesterol and Fatigue

High cholesterol is a well-known risk factor for cardiovascular diseases, but its potential link to fatigue is less commonly discussed. Recent research has begun to explore whether high cholesterol levels can contribute to feelings of tiredness and fatigue, particularly in conditions like multiple sclerosis (MS) and chronic fatigue syndrome (CFS).

High Cholesterol and Fatigue in Multiple Sclerosis

HDL Cholesterol and MS Fatigue

In patients with relapsing-remitting multiple sclerosis (MS), fatigue is a common and debilitating symptom. A study investigated the relationship between cholesterol biomarkers and fatigue in these patients. The findings revealed that higher levels of high-density lipoprotein cholesterol (HDL-C) were associated with lower fatigue severity scores. Conversely, a higher total cholesterol (TC) to HDL-C ratio was linked to increased fatigue. This suggests that maintaining a healthy lipid profile, particularly higher HDL-C levels, might help reduce fatigue in MS patients.

Diet-Based Interventions and Fatigue Reduction

Another study focused on progressive MS patients undergoing a diet-based multimodal intervention, which included dietary changes, exercise, and stress reduction. The results showed significant improvements in fatigue levels, which were associated with increases in HDL-C and decreases in total cholesterol and triglycerides (TG). This further supports the idea that lipid profiles can influence fatigue levels in MS patients.

Chronic Fatigue Syndrome and Lipid Peroxidation

Oxidative Stress and Lipid Peroxidation

Chronic fatigue syndrome (CFS) is another condition where fatigue is a primary symptom. Research has indicated that oxidative stress, particularly lipid peroxidation (LPO), plays a role in CFS. Elevated levels of malondialdehyde (MDA), a marker of LPO, were found in female CFS patients. These high MDA levels were negatively correlated with HDL-C levels and positively correlated with TG levels, suggesting that lipid peroxidation might contribute to fatigue in CFS .

Sleep Disorders, Physical Activity, and Cholesterol

Sleep Duration and Cholesterol Levels

Sleep duration has also been linked to cholesterol levels and fatigue. A study found that short sleep duration in adolescence was associated with higher total cholesterol and lower HDL-C levels in young adulthood. This relationship was particularly significant in females, indicating that insufficient sleep could contribute to hypercholesterolemia and potentially fatigue.

Physical Activity and Sleep Disorders

In patients with high cholesterol, intense physical activity at work was found to be a risk factor for sleep disorders. These sleep disturbances could exacerbate feelings of fatigue, highlighting the complex interplay between physical activity, sleep, and cholesterol levels.

Conclusion

The research suggests a significant link between high cholesterol levels and fatigue, particularly in conditions like multiple sclerosis and chronic fatigue syndrome. Higher HDL-C levels and lower total cholesterol to HDL-C ratios appear to be associated with reduced fatigue. Additionally, factors like sleep duration and physical activity also play crucial roles in managing cholesterol levels and fatigue. Maintaining a healthy lipid profile through diet, exercise, and adequate sleep may help mitigate fatigue associated with high cholesterol.
