Liver Diabetes

Abnormally high systemic iron levels can lead to cirrhosis of the liver, diabetes mellitus, and heart failure. Although a number of disease processes can lead to iron overload, this chapter focuses on hereditary hemochromatosis, the prototypical disease of iron overload. 

Iron overload may occur as a result of metabolic defects, such as idiopathic hemochromatosis—an inherited disease, or from high intakes of iron. The clinical signs and symptoms of iron overload may include hyperpigmentation of the skin, cirrhosis of the liver, diabetes, and myocardial failure. Dr. John R. K. Robson, M.D., one of the coauthors of this book, has observed excessive intakes of iron, characterized by hemosiderosis and cirrhosis of the liver, in the Bantu tribe of South Africa who cook their food in iron pots and ferment their beer in iron utensils—and who have iron intakes of up to 100 mg, or more, per day. 

DISORDERS WHICH ARE OFTEN AGGRAVATED BY OBESITY. Statistics from the Metropolitan Life Insurance Company show that obese people (those who are more than 20% overweight) have significantly higher death rates than the nonobese from such conditions as appendicitis, cancers of the gallbladder and liver, cirrhosis of the liver, diabetes, gallstones, heart disease, hernia and intestinal obstruction, kidney disease, stroke, and toxemia of pregnancy. 

Most of the herbal drugs that are used medicinally are comprised in these five groups of indications. Relative few are employed in a limited number of other areas occasionally in skm remedies, liver remedies, coronary remedies, blood circulation remedies, and in other groups of medicines. Summarizing, it can be said that the possibilities of treatment with herbal drugs are limited for a number of reasons for a series of illnesses like severe cardiac insufficiency, tumours, infectious diseases, diabetes, etc., herbal drugs arc not adequate remedies, even though, in contravention of the law, such claims are made in many publications. In a series of further cases, they only find use in support of the actual medical treatment they are nevertheless of value. 

Insulin is a peptide hormone, secreted by the pancreas, that regulates glucose metabolism in the body. Insufficient production of insulin or failure of insulin to stimulate target sites in liver, muscle, and adipose tissue leads to the serious metabolic disorder known as diabetes mellitus. Diabetes afflicts millions of people worldwide. Diabetic individuals typically exhibit high levels of glucose in the blood, but insulin injection therapy allows diabetic individuals to maintain normal levels of blood glucose. 

Obesity and hyperglycemia 2. 2-AG levels are elevated in mouse adipocytes and epididymal of mice with DIO. AEA and 2-AG levels are elevated in rat insulinoma p-cells, in pancreas of mice with DIO, and in obese women. Patients with obesity or hyperglycaemia caused by type 2 diabetes exhibit elevated levels of 2-AG or of both endocannabinoids in visceral fat or blood, respectively. AEA levels are elevated in the liver of DIO mice 2. CB1 antagonists... 

Insulin resistance occurs when the normal response to a given amount of insulin is reduced. Resistance of liver to the effects of insulin results in inadequate suppression of hepatic glucose production insulin resistance of skeletal muscle reduces the amount of glucose taken out of the circulation into skeletal muscle for storage and insulin resistance of adipose tissue results in impaired suppression of lipolysis and increased levels of free fatty acids. Therefore, insulin resistance is associated with a cluster of metabolic abnormalities including elevated blood glucose levels, abnormal blood lipid profile (dyslipidemia), hypertension, and increased expression of inflammatory markers (inflammation). Insulin resistance and this cluster of metabolic abnormalities is strongly associated with obesity, predominantly abdominal (visceral) obesity, and physical inactivity and increased risk for type 2 diabetes, cardiovascular and renal disease, as well as some forms of cancer. In addition to obesity, other situations in which insulin resistance occurs includes... 

This drug is contraindicated in individuals who have had previous hypersensitivity reactions to pentamidine isethionate. Pentamidine isethionate is used cautiously in patients with hypertension, hypotension, hyperglycemia, renal impairment, diabetes mellitus, liver impairment, bone marrow depression, pregnancy (Category C), or lactation. 

The gold compounds are used cautiously in patients with a history of hypersensitivity to other drugs, previous kidney or liver disease, diabetes, or hypertension. 

The MAOI antidepressant drag s are contraindicated in patients widi known hypersensitivity to die drug s, liver and kidney disease, cerebrovascular disease, hypertension, or congestive heart failure and in die elderly. These drag s are given cautiously to patients witii impaired liver function, history of seizures, parkinsonian symptoms, diabetes, or hyperthyroidism. 

Loop diuretics are used cautiously in patients with renal dysfunction. The loop diuretics are Pregnancy Category B (ethacrynic acid and torsemide) and C drugp (furosemide and bumetanide) and must be used cautiously during pregnancy and lactation. Furosemide is used in children but should be used cautiously. The loop diuretics are used cautiously in patients with liver disease, diabetes, lupus erythematosus (may exacerbate or activate the disease), or diarrhea. Patients with... 

Fatty acids are synthesized by an extramitochondrial system, which is responsible for the complete synthesis of palmitate from acetyl-CoA in the cytosol. In the rat, the pathway is well represented in adipose tissue and liver, whereas in humans adipose tissue may not be an important site, and liver has only low activity. In birds, lipogenesis is confined to the liver, where it is particularly important in providing lipids for egg formation. In most mammals, glucose is the primary substrate for lipogenesis, but in ruminants it is acetate, the main fuel molecule produced by the diet. Critical diseases of the pathway have not been reported in humans. However, inhibition of lipogenesis occurs in type 1 (insulin-de-pendent) diabetes mellitus, and variations in its activity may affect the nature and extent of obesity.
