anxiety can increase bad cholesterol

My doctor said my bad cholesterol was high. It seems impossible because I eat very well and avoid foods high in cholesterol. The only thing it could be is that my anxiety has been high over the last year. Can anxiety increase bad cholesterol?

Yes, anxiety can increase bad cholesterol.

Anxiety activates the stress response. The stress response secretes stress hormones into the bloodstream, where they bring about specific physiological, psychological, and emotional changes that prepare the body for immediate action.[1][2]

You can read more about the many changes caused by the stress response in our “Stress Response” article.

Since stress responses push the body beyond its balance point (equilibrium), stress responses stress the body. As such, anxiety stresses the body.

Regarding your question, research shows stress can increase bad cholesterol (low-density lipoprotein - LDL).[3][4][5][6][7][8]

Consequently, the more anxious you are, the more likely your bad cholesterol will rise.

You can reduce bad cholesterol by continuing to eat a healthy diet, reducing stress, increasing rest, regular deep relaxation, regular exercise, getting good sleep, and dealing with your anxiety issues.

In fact, research shows that regular exercise, regular deep relaxation, and getting good sleep are natural and practical strategies that can go a long way to reducing bad cholesterol.[9][10][11]

As well, dealing with your anxiety issues can also greatly help reduce bad cholesterol.

Working with an experienced anxiety disorder therapist is the most effective way to overcome issues with anxiety.

The combination of good self-help information and working with an experienced anxiety disorder therapist, coach, or counselor is the most effective way to address anxiety and its many symptoms. Until the core causes of anxiety are addressed – which we call the underlying factors of anxiety – a struggle with anxiety unwellness can return again and again. Dealing with the underlying factors of anxiety is the best way to address problematic anxiety.
