Bad cholesterol and good mood: exploring the link

It is a well-known fact that high cholesterol increases the risks of heart disease. Hence, physicians actively encourage cholesterol-lowering interventions using medications and lifestyle modifications. However, there is considerable evidence that aggressive lowering of cholesterol is associated with depression, bipolar disorders, violent behaviour, and suicidal ideation. It has been hypothesised that low cholesterol leads to low levels of serotonin, a chemical that is responsible for maintaining mood balance. South Korea and India have highest number of suicides in Asia. It is a significant challenge for physicians to search an alternative that will not only maintain healthy level of cholesterol, but also contribute to psychological well-being of the patient. Generally, the role of diet and physical activity is considered secondary to medications. However, dietary supplements like coenzyme Q10 (CoQ10), omega-3 fatty acids, niacin, and physical activity like Yoga are extremely beneficial for improving lipid profile and symptoms of depression.
