INTRODUCTION TO THE TOPIC

“...obesity is essentially an inflammatory disease”, according to Gökhan Hotamisligil, professor of genetics and metabolism at the Harvard School of Public Health. “Excess calories affect the fat cells in such a way that they mount an immune response. You’re activating the immune system without a legitimate pathogen. You’re constantly activating your immune system at a low level in such a way that it releases chemicals that start contributing to inflammation.” (Quoted in “Fat chance: the biology of obesity” on the web site of the Whitehead Institute for Biomedical Research, June 22, 2005. Original article written by David Cameron in the Spring 2005 issue of the magazine Paradigm)

More than one third of U.S. adults and 16% of U.S. children are obese. Being obese, whether by genetic factors, metabolism, hormonal imbalances or changes (e.g., menopause), body type (most likely endomorph), medical conditions, such as hypothyroidism or Cushing’s disease, side effects of medication, smoking cessation, or poor lifestyle habits, can lead to early mortality. Obesity can contribute to a multitude of health effects, including problems with:

  • the respiratory system and sleep (sleep apnea; asthma; breathlessness)
  • the digestive system (GERD; gallbladder disease & gallstones; eating disorders)
  • the reproductive system (menstrual problems; pregnancy complications; infertility; impotence; birth defects; PCOS-polycystic ovary syndrome)
  • the endocrine system (pancreatitis; fatty pancreas)
  • the cardiovascular system (heart attack; elevated cholesterol/atherosclerosis; abnormal heart rhythms; hypertension; peripheral vascular disease; stroke)
  • mental health (depression)
  • liver (nonalcoholic fatty liver disease-NALD; nonalcoholic steatohepatitis-NASH)
  • kidneys (kidney stones; chronic kidney disease-CKD)
  • the musculoskeletal system (osteoarthritis in the back, hips, knees; gout)
  • the immune system (inflammation; lowered immunity)

Obesity can cause complications in surgery and with anesthesia. It has been implicated in Alzheimer’s. It often leads to metabolic syndrome and type 2 diabetes. It is a factor in cancers, such as ovarian, endometrial, postmenopausal breast cancer, colorectal, prostate, and others. A link has been found between migraine and obesity. And, of course, obesity affects an individual’s general quality of life, self-esteem and self-image.

A person is considered obese if the body mass index, which is based on height and weight, is 30 or greater (40 or greater is morbidly obese; 25-29 signifies overweight).

Waist measurement is a good indicator of abdominal fat. Men with a waist circumference of 40 inches or more and women with 35 inches or more are at increased risk of adverse health effects, such as heart disease. Another indicator of health risks is the waist-to-hip ratio, which indicates if you have an apple or a pear shaped body (those with a pear shape are less prone to health problems):
