Obesity: Cause, Consequences and Implications

There are many causes and health implications of obesity. Many people are in illusion about the quantitative parameters of obesity. The obesity can be defined in terms of Weight/Height (^W/_H) ratio or index: where weight is in kilograms (kg) and height is in meters (m). This index should be 25 to 30 normally. If your weight is 47 kg and your height is 1.60 m (160 cm); your ^W/_H index will be 29.375. An ideal weight of an individual with reference to sex, age, height and body build has already been documented somewhere else. The cause of obesity may be genetic, metabolic, physiological, lifestyle or pathological (as in cases of hypothyroidism). Take your weight on the same scale daily for a week. If you are overweight or your ^W/_H index is considerably more than 30, then plan to loose your weight through dieting and exercise. Never starve yourself. You can eat as desired from the unrestricted food items' list but remain within limits on restricted food items' list and keep away from prohibited food items' list:

Unrestricted Food Items' List
Unrestricted food items for the obese are fresh fruits, fresh vegetables, chicken, fish, poached eggs, boiled eggs (do not eat yellows), tea, coffee, skimmed milk and products made from skimmed milk.

Restricted Food Items' List
Restricted food items for the obese are all cereals and products made from cereals. Obese person should avoid eating more than 100 gm cereal products in a day. Fat consumption should not be more than 15 gm in 24 hours.

Prohibited Food Items' List
Prohibited food items for the obese are jams, honey, ice cream, dry fruits, nuts, cold drinks, alcohol, sugar and products containing sugar.


Obesity is associated with hyperlipidemia (elevated level of cholesterol and triglyrerides in blood), hypertension (high blood pressure), non-insulin dependent diabetes mellitus (NIDDM) and high prevalence of some cancers. Other serious implications of obesity are coronary heart disease and renal disease. Abdominal fat has been documented as major risk factor for coronary heart disease. The risk of NIDDM is more in overweight men aged between 25-50 years of age. The patient is said to have severe obesity if his ^W/_H index is more than 40. Natural history and consequences of obesity in children are not well understood till date. Strict dietary control and weight reduction would definitely help patients with severe obesity to overcome its serious implications like - NIDDM, hyperlipidemia, hypertension and coronary heart disease.

All Diabetics are not Alike!

All diabetics are not alike, so never take medicines for diabetes on the advice of fellow patients. The term diabetes means inordinate and persistent excretion of excessive volume of urine. Diabetes is a disease of carbohydrate metabolism with a variety of causes. Pancreas is directly associated with carbohydrate metabolism and biobalance of blood sugar (glucose) level. All carbohydrates (starches, polysaccharides, disaccharides and monosaccharides) are converted into glucose in our stomach and small intestine, absorbed in blood and taken to liver for storage in liver cells as glycogen for future use. Glycogen is also stored into muscle cells and utilized for muscle function. Insulin produced by the beta-cells in the pancreas helps in the penetration of glucose into liver and muscle cells and further storage as glycogen. Glucagon produced by alpha-cells of the pancreas regulates the conversion of glycogen in glucose through glycogenolysis, when ever glucose level in the blood falls below normal.

Defective metabolism of carbohydrates may lead to alimentary diabetes. The term diabetes insipidus pertains to a condition characterized by excessive intake of water with excessive urination but without any glycosuria (excretion of glucose in urine). Diabetes insipidus due to congenital failure of renal tubules to respond to anti-diuretic hormone (ADH) is termed as diabetes insipidus nephrogenic. Diabetes mellitus (DM) is a condition characterized by an elevated level of sugar (glucose) in blood and urine. Diabetes mellitus may affect both younger (juvenile diabetes) and older people (maturity onset diabetes). Subclinical diabetes refers to a condition where glucose tolerance test is abnormal but clinical signs of diabetes like polyuria (excessive urination with increased frequency of micturition), hunger, thirst and weight loss are absent. Obesity may be associated with diabetes but all obese people could never be diabetics. Fat metabolism is also impaired in diabetes which may lead to hypercholesterolemia and hypertension (high blood pressure) in diabetics. There is a strict need of controlling hypertension and hypercholesterolemia with customized diet, regular exercise and sometimes with medicines. It is advisable never to copy your fellow patient's treatment. Diabetes need your round the clock commitment and if taken care it would reduce your risk of serious complications like renal disease.

Important Tip: Never copy your fellow patient's treatment.
