The Hidden Impact: Heart and Digestive Complications

One of the most dangerous aspects of Chagas disease is its ability to silently damage vital organs over time. After an initial acute phase—which often presents with mild or no symptoms—the disease can enter a chronic stage that lasts for decades.

During this period, the parasite remains in the body and can progressively damage the heart. Approximately 20–30% of infected individuals will develop chronic Chagas cardiomyopathy, which can lead to:

• Irregular heart rhythms (arrhythmias)

• Enlarged heart (cardiomegaly)

• Heart failure

• Sudden cardiac death

In some cases, Chagas disease also affects the digestive system, causing enlargement of the esophagus or colon, leading to difficulty swallowing or severe constipation.

Because symptoms often appear late, many people are diagnosed only after irreversible damage has occurred. Early detection through blood testing is the most effective way to prevent severe complications. Increased awareness among healthcare providers in both the U.S. and Latin America is essential to improving outcomes.
