Researchers are discovering more ways that obesity can damage the body. These include altering a person's ability to smell, disrupting sleep and sexual function, and accelerating cancerous tumor growth.
"Obesity is a complex condition," "Many, many things change in the body."
Fat produces numerous hormones, inflammatory molecules and other chemicals that can act directly on nearby organs or travel to wreak havoc in other areas of the body. Better understanding how this works might eventually open new avenues for treatment of obesity and linked conditions, experts say.
