What do you think about the process by which such things as hyperactivity and obesity are now seen as medical conditions as opposed to behavioral problems?

Obesity is excess weight, defined as a body mass index (BMI) ≥30 kg/m2. Complications include cardiovascular disorders (especially in people with excess belly fat), diabetes, certain cancers, gallstone disease, fatty liver, cirrhosis, degenerative joint disease, and reproductive disorders. in men and women, psychological distress, and premature death for those with BMI ≥ 35. Diagnosis is based on body mass index. Treatment includes lifestyle changes (eg, in diet, physical activity, and behavior), and, for some patients, medications or weight loss surgery (weight loss).

So it's a disease, not a behavioral problem
