No: Lab ranges are set so that a few percent of healthies arbitrarily fall outside on either end. Be glad, as long as you feel well.

Perhaps slightly: Most doctors think cholesterol is just something that clogs arteries but most chol. is made by our bodies as an essential component of cell membranes and building block for steroid hormones. Evidence suggests that low chol. is associated with increased risk of heart disease, heart failure, stroke and cancer. But Drs. know more about lowering chol. than raising it.

It's complicated because some people don't produce enough cholesterol because they're in failing health, so the increased risk of disease may not be directly caused by low chol. but by the reasons it's low. Chol. is also determined by genetics and those with genetically low chol. may not be at increased risk; more research is needed but there is a correlation between low chol. and increased risks.
