Studi kaitkan obat GLP-1 dengan risiko kerontokan rambut ringan

Analisis baru terhadap catatan pasien menunjukkan bahwa orang dewasa dengan diabetes tipe 2 yang mengonsumsi agonis reseptor GLP-1 menghadapi tingkat alopecia yang lebih tinggi dibandingkan mereka yang menggunakan obat diabetes umum lainnya.

Studi yang diterbitkan pada 22 Juli 2026 di The BMJ ini memeriksa catatan kesehatan elektronik dari Penn Medicine yang mencakup pasien yang dirawat dari Januari 2019 hingga September 2024.

Setelah penyesuaian untuk usia, jenis kelamin, indeks massa tubuh, dan faktor lainnya, pengguna GLP-1 menunjukkan risiko alopecia 37 persen lebih tinggi dibandingkan pengguna penghambat SGLT-2 dan risiko 68 persen lebih tinggi dibandingkan pengguna penghambat DPP-4.

Peningkatan risiko ini terbatas pada alopecia non-sikatrikal, suatu bentuk yang memungkinkan rambut untuk tumbuh kembali. Tingkat absolut tetap rendah, yaitu sekitar 6 hingga 7 kasus per 1.000 tahun-orang.

Para peneliti mencatat bahwa penurunan berat badan yang cepat terkait dengan obat-obatan tersebut dapat berkontribusi pada efek tersebut melalui kekurangan nutrisi atau perubahan hormon, meskipun studi tersebut tidak dapat memastikan hubungan sebab akibat.

A large review of cardiovascular outcome trials found that people taking GLP-1 receptor agonists—drugs that include semaglutide (sold as Ozempic)—had a lower risk of major heart-related events than those given placebo. The analysis pooled results from 11 trials involving more than 90,000 participants, with an average follow-up of nearly three years, and reported benefits across patient subgroups including those with and without diabetes.

A new experimental oral medication called elecoglipron improved blood sugar control and promoted weight loss in adults with type 2 diabetes during a phase 2b trial. Results from the SOLSTICE study were presented at the American Diabetes Association's Scientific Sessions and published in The Lancet.

A year-long observational study in Japan suggests that people with type 2 diabetes who tend to overeat in response to tempting food cues such as sight and smell may see greater weight loss—and possibly better blood-sugar improvement—after starting GLP-1 receptor agonists, while those with primarily emotional eating patterns show less consistent links to long-term outcomes.

Researchers say genetic variants in the PAM gene may help explain why some people with Type 2 diabetes get less blood-sugar benefit from GLP-1 receptor agonist drugs such as Ozempic, a phenomenon they describe as “GLP-1 resistance.”

A study from Rutgers University reports that adults currently using GLP-1 receptor agonist medications—including semaglutide brands Ozempic and Wegovy—showed a substantially weaker association between impulsivity and self-reported violent behavior than former users. The research, published June 17, 2026 in the journal Criminology, was based on a 2025 U.S. survey and does not establish cause and effect.

Stanford Medicine researchers say they have identified a naturally occurring 12–amino-acid peptide, BRP, that suppressed appetite and reduced body weight in animal studies. The team used a computational tool dubbed “Peptide Predictor” to identify the molecule, and reported that BRP produced anti-obesity effects in mice and minipigs without signs of nausea- or aversion-like responses seen with some GLP-1–based drugs.
