Eating spicy and other irritating foods can accumulate heat in the stomach and endogenous heat evil.

2. The diet of cor pulmonale should be light vegetarian. Chinese medicine has always advocated vegetarian health. People often say that "fish makes a fire, meat produces phlegm, and vegetables and radishes keep safe." Patients with cor pulmonale have poor physical strength, little activity and are prone to constipation. Eating meat is not easy to digest because of digestive dysfunction. Therefore, we should eat more nutritious and digestible foods such as vegetables and fruits.

At the same time, due to right heart dysfunction, gastrointestinal congestion affects digestion and absorption, reducing appetite. Therefore, we should provide patients with a nutritious and digestible diet, eat more high-quality protein such as milk and eggs, and supplement protein. Pay attention to eat less and eat more meals to ensure nutrient supply and not increase the burden on the stomach.
