Scientists found that gut microbes play a key role in protecting against heart disease caused by sleep apnea. They studied mice and discovered that removing a specific receptor helped reduce plaque buildup in arteries.

Millions of people worldwide suffer from obstructive sleep apnea, a condition that interrupts breathing during sleep. New research suggests that gut microbes may help protect against some serious consequences, including heart disease. The study was presented at ASM Microbe 2026 and found that microbially modified bile acids can regulate the development of cardiovascular disease during sleep apnea-like conditions.

The researchers studied two groups of mice: one prone to heart disease and another with a specific receptor missing. Both groups were exposed to normal sleeping conditions or conditions mimicking sleep apnea. The team analyzed fecal samples to track changes in gut microbes and metabolites, and examined plaque buildup in the animals' arteries.

The results showed that removing the receptor significantly reduced plaque buildup in some areas and minimized disruptions to the gut microbiome. Mice without the receptor developed less plaque in the aorta and aortic arch, although some remained in the pulmonary artery.

Why It Matters

This study is important for Indian students because it highlights the connection between gut health and heart disease. Maintaining a healthy diet and lifestyle can help prevent sleep apnea and its complications.
