Nurse here also... I have to seriously disagree with the previous poster. Yes, there is definitely such a thing as having too low cholesterol! It is far, far too long that the medical community made blanket statements like "...no such thing as cholesterol being too low"! This statement is totally incorrect and lacks logical reasoning. Low cholesterol can lead to Depression, Mental Fatigue, Brain "Fog", Heart Disease, and a whole host of other VERY serious symptoms. While I don't necessarily think 124 is TOO low, it is on the low range and should be monitored periodically. The human brain is largely made of cholesterol, low cholesterol in brain cells has harmful effects on memory, concentration and mood. Twenty-five percent of all cholesterol found within the body is found in brain cells, if your levels dip too low, it can seriously impair your brain function, which in turn affects every other organ in your body. Research is being conducted now that shows that doctors using cholesterol suppressing drugs may be seriously impacting the quality and value (as well as length) of their patients lives by trying to get them close to the 100 range, which is NOT healthy for any part of your body. According to research studies, patients on cholesterol lowering drugs (statins) have only a very slight reduction (<0.7% - that's less than 7 out of 1000 people) in death rate (these studies were funded by the manufacturers themselves which is a huge conflict of interest). Other studies recently published have shown NO reduction in death rate by taking statins, in fact, more studies have shown a higher incidence of heart disease by those individuals taking statins.
