Low cholesterol is caused primarily by an inherited condition. If it runs in the family, then it is most likely normal for the individual involved. It can be secondarily caused by medical conditions such as hypolipidemia, which is marked by extremely low cholesterol, hyperthyroidism, which is a disease of the thyroid gland, and liver disease. Malnutrition, chronic infections, depression, anxiety, stroke and birth defects are all causes of low cholesterol. Manganese deficiency, any condition that suppresses the appetite, such as cancers of the digestive tract or stomach, lung diseases, or liver disease can all create low cholesterol due to the lowered food intake.
Addictions and Deficiencies
The body cannot survive without cholesterol, so when it is too low the entire body suffers from the deficiency. Addictions to alcohol, cigarettes or drugs can radically lower cholesterol levels as can undiagnosed cancers and emotional disorders. A deficiency in Manganese also causes hypocholesterolemia. When the digestive tract is functioning insufficiently, and is not absorbing nutrients properly, the result is usually low cholesterol.
Damage to Cells and Organs
When these cholesterol-lowering conditions come into play, many different problems can result, including diseases of the brain and neural system and the breaking down of the cellular structures of every part of the body, including the internal organs. When cells are damaged cancers can result. Cancer is a cause of low cholesterol in the first place, but low cholesterol damage in the cells can go on to create more cancerous tumors. The immune system becomes damaged due to the lowered cholesterol levels, which causes many more harmful conditions to develop.
