Sleep Apnea Risk

Excess neck fat can constrict the airway, leading to breathing difficulties during sleep.

High Blood Pressure Cause

Extra body fat requires more blood flow, increasing pressure on artery walls.

Fatty Liver Disease

A liver condition resulting from excess fat accumulation in the liver.

Gallstones in Obesity

Obesity can increase the risk of gallstones due to higher cholesterol levels in bile or inefficient gallbladder function.

Obesity and Insulin Resistance

Excess body fat can make the body's cells resistant to insulin, a hormone that moves sugar from the blood to cells for energy. This resistance prevents sugar from entering cells, leading to high blood sugar.

Study Notes

Overweight and Obesity

  • Obesity is a condition where a person has a harmful amount of body fat or an unhealthy fat distribution
  • It increases the risk of serious health problems
  • Excess body fat puts strain on bones and organs, causing hormonal and metabolic changes, leading to inflammation
  • People with obesity have a BMI of 30 or higher

Body Mass Index (BMI)

  • BMI is a measure of body composition, calculated by dividing weight (kg) by height (m) squared (kg/m²)
  • It helps determine if a person's weight is healthy
  • A BMI of 25-29.9 is considered overweight, while a BMI of 30 or above is considered obese
  • BMI ranges for adults: 18.5 to 24.9 is healthy, >25 is classified as overweight, >30 is obese

BMI Accuracy

  • BMI considers variations in body shape
  • Healthcare professionals may consider other factors
  • Muscle-dense individuals may have a higher BMI but be within a healthy weight range
  • Ethnic background may also affect risks of health conditions, for example South Asians may develop diabetes or other health complications at a lower BMI
  • Type 2 diabetes: High blood sugar levels, increasing risk of heart disease, nerve damage, stroke, kidney disease, and vision problems
  • Heart disease: Fatty deposits accumulate in arteries leading to high blood pressure, low-density lipoproteins (LDL) cholesterol, triglycerides, and blood sugar problems. Narrowed arteries can lead to heart attacks and strokes
  • Stroke: Blood supply to the brain is cut off, leading to brain damage and disabilities such as speech, language impairment, weakened muscles, and thinking/reasoning problems
  • Sleep apnea: Momentary breathing stops during sleep, a risk higher for overweight and obese people.
  • High blood pressure: Extra fat requires more blood causing higher pressure on artery walls
  • Liver Disease: Fatty liver disease, or nonalcoholic steatohepatitis (NASH), excess fat in the liver, can lead to liver damage (scar tissue - cirrhosis) and liver failure
  • Gallbladder disease: Gallbladder stores bile and passes it to the small intestine for fat digestion. Gallstones can form due to bile build up or large gallbladder size leading to pain and surgery
  • Certain cancers: Increased risk of cancers like breast, colon, gallbladder, pancreatic, kidney, prostate, uterus, cervix, endometrium, and ovaries
  • Pregnancy complications: Risks of insulin resistance, high blood sugar, and high blood pressure. Complications during pregnancy and delivery are higher.
  • Depression: Body size discrimination can lead to sadness and lack of self-worth, linked to obesity

How to Lower Obesity Risk

  • Losing 5% of body weight can reduce risk of health complications, including diabetes and heart disease
  • A combination of diet and consistent exercise can help reduce weight over time
  • Moderate exercise of 150 minutes per week (or increasing to 300) can be beneficial along with strengthening exercises
  • Healthier eating habits include filling half your plate with vegetables, replacing refined grains with whole grains, eating proteins like lean meats, seafood, beans, and soy, and avoiding fried, fatty, and sugary foods and drinks.
