Using incorrect concentrations. If your vitamin C standard solution is too concentrated or your iodine titration solution is too diluted, or your starch indicator solution is not between 0.5 to 1.0%, it may require much more than 50 mL of iodine solution to titrate the standard solution and/or orange juice.
The following summarizes some common causes of fatigue but is not meant to be comprehensive: Metabolic/endocrine: anemia; hypothyroidism; diabetes; electrolyte abnormalities; kidney disease; liver disease; Cushing's disease.
Researchers have noted that exhaustion and fatigue are the single most common symptom of liver damage, and it typically has a significant and damaging impact on the patientâs quality of life. Unfortunately, the specific causes of liver disease-related fatigue and exhaustion are not fully understood. Researchers speculate that the root cause of liver disease-related chronic fatigue may be caused by changes in brain chemistry and hormone levels which result from impaired liver function. In particular, altered levels of corticotropins, serotonin, and noradrenaline may be at the root of depleted energy levels.
