Liver Disease: The liver is the bodys filter for toxins and is the main metabolic engine for creating new proteins.
AST: Aspartate aminotransferase (AST) is an enzyme found in liver, muscle, and heart tissues. Increased levels of AST can be seen with liver diseases (e.g., hepatitis), and injury or disease to the muscles. The AST test is often done to determine liver function in conjunction with other tests, including alanine aminotransferase (ALT) and alkaline phosphatase (ALP).
BILIRUBIN: Bilirubin is a breakdown product from the hemoglobin released from dying red blood cells and is elevated if the liver or gallbladder are too congested to process this waste product.
Heart Failure: The heart cannot pump enough blood to the body; its not hard to understand why fatigue occurs.
B-type natriuretic peptide (BNP): Its produced only in the ventricles of the heart. Increased levels may indicate heart failure. There is strong correlation between the degree of heart failure and the BNP level. Studies suggest that the BNP may have important prognostic significance in people with acute coronary syndrome (ACS). If your BNP is significantly elevated, heart disease may be the cause of your fatigue.
Vitamin Inadequacies: Specific vitamin levels.
Vitamin B12 is important for metabolism, the formation of the red blood cells, and the maintenance of the central nervous system. A deficiency of vitamin B12 may occur as a result of an inability to absorb the vitamin from food. It can also occur in strict vegetarians who do not consume any animal foods. Some individuals who develop a vitamin B12 deficiency have an underlying stomach or intestinal disorder that limits the absorption of vitamin B12.
Vitamin D is essential for enabling the digestive system to absorb calcium and phosphate. It also causes the release of calcium from bone into the bloodstream. Vitamin D is also required for normal development of teeth and bones, and its important for normal immune and cardiovascular functioning. The body acquires and activates vitamin D from particular food sources and exposure to ultraviolet radiation or sunlight.
Bowel Diseases: Chronic bowel problems and parasitic diseases can also rob you of energy and cause fatigue.
Tisue transglutaminase (tTG): Certain antibodies can signal inflammation within the small intestine. tTG is an antibody that indicates gluten (wheat, barley, rye, oat) intolerance, also known as celiac disease. Some people with celiac disease do not absorb important nutrients well and as a result may become chronically fatigued.
Antibodies for gluten (wheat, barley, rye, oat) intolerance.
Stool for ova and parasites.
