abnormally low cholosterol?

In the past two years, my total cholesterol has fallen from 131 to 101 even though I've gained 25 to 30 pounds and eaten a diet that includes meat.  I'm a 51 year old woman, with blood pressure averaging around 100 over 70.  I've been experiencing fatigue, but no other symptoms.  Should I be worried about my cholesterol?  And should I consider my HDL of 37 poor because it's under 50 or good because it represents such a high percentage of the total number?  Thanks.

Your HDL should be higher (37 is low for females).  Have you tried eating dark chocolate (sugarless)?  Do you eat any salmon, which has the omega 3?  Salmon, dark chocolate, tea have been shown to raise HDL levels.  LDL should be under 100, HDL in the 50's, and triglyercides under 150.  My LDL is 79, HDL is 52 and triglycerides are 35.  We have heart disease in the family, so I am monitoring my cholesterol levels carefully every year.  If you are feeling tired, make sure that you are drinking enough water, eating healthy, getting enough vitamin D, vitamin B's in your diet and if not take a supplement.  If you are doing all these and still feeling tired, you should see your doctor about having an echocardiogram to check your heart valves.  The main symptom of heart valve problems is tiredness.  Watch your fat intake.  Fat can really make a person tired after eating it.
