Many people consider addiction to be a problem of personal weakness, initiated for self-gratification and continued because of an unwillingness or lack of sufficient willpower to stop. However, within the medical and scientific communities, the notion that pleasure-seeking exclusively drives addiction has fallen by the wayside.

People typically engage in psychoactive experiences to feel good and to feel better. The roots of addiction reside in activities associated with sensation seeking and self-medication.
A new medication for the treatment of obesity has been approved by the FDA, and it received significant media attention in the months leading up to its approval.

Older Americans are keeping their teeth longer, but the prevalence of tooth loss is higher among people with chronic disease or overall worse health. However, loss of a tooth can also result from tooth decay, periodontal infection, or accidental trauma.

Several companies promote at-home genetic testing to uncover a range of potential health problems (and, in some cases, ancestry traits). Just how useful is this and how do such tests differ from genetic testing a doctor may recommend for medical reasons?
Some air pollution levels have inched up in recent years, and accumulating evidence suggests that higher levels of particulates in the air are linked with increased levels of hospitalization for many serious health problems. But we can make choices to help both the environment and our health.
Aortic stenosis is the narrowing of the aortic valve in the heart, which can lead to heart failure if the problem is not identified and treated. Unfortunately, research shows that inequities exist in access to proper diagnosis and care for this condition. Understanding how stenosis is identified and treated can help you receive good care.
Though recently discovered, the endocannabinoid system regulates and controls many of our critical bodily functions. Researchers are investigating the ECS’s role in learning and memory and in hunger, hoping that these avenues of research may lead to new drug discoveries.
