New Oral Medications May Help Control Food Cravings

Topic: Health

Scientists have found that some new oral medications can reduce food cravings by affecting a specific part of the brain. The study was conducted on mice and used gene-editing techniques to understand how these medications work.

Popular weight-loss and diabetes medications like semaglutide belong to a group called GLP-1 drugs. A recent study funded by the National Institutes of Health (NIH) has discovered a new way that some oral GLP-1 drugs may affect the brain.

The researchers used gene-editing techniques to modify GLP-1 receptors in mice, making them more similar to those found in humans. They then gave the mice either orforglipron or danuglipron and examined which parts of the brain became active. The study found that these medications affected a region called the central amygdala, which is involved in desire and reward.

This is important because it suggests that oral GLP-1 drugs may influence more than just physical hunger. They may also weaken the pleasurable signals that make certain foods especially tempting. The researchers now want to determine whether these medications can reduce cravings for substances other than food.

Why It Matters

Understanding how these medications work could lead to new treatments for substance use disorder and obesity, which are major health concerns in India.
