đš Obesity isnât a weakness â itâs a disease. And scientists may have found a hormone that can help treat it.
Here's what to know about PYY.
Obesity is increasingly recognized by medical experts as a chronic disease, not a matter of willpower or personal failure.
Among the most promising areas of research into obesity treatments is the study of hormones that regulate hunger and fullness.
One such hormone, Peptide YY (PYY), is gaining attention for its powerful role in appetite control. Produced in the gut after eating, PYY signals the brain that the body is full, helping to reduce food intake and support energy balance.
Recent studies have found that administering PYY can suppress appetite in both obese and non-obese individuals, suggesting it could be an effective tool in treating obesity. Researchers are now exploring new therapies based on PYY, including synthetic analogues and hormone combination treatments. While the results so far are encouraging, scientists caution that more research is needed to ensure the long-term safety and effectiveness of these therapies. Still, PYY represents a hopeful step toward treating obesity not with blame, but with science.
