What diseases can affect both spouses?

Couples may commonly suffer from certain diseases together, including sexually transmitted infections, digestive system disorders, skin conditions, metabolic diseases, and "couple cancers." The details are as follows:

1. Sexually Transmitted Diseases: Sexually transmitted infections such as syphilis, AIDS, genital warts, as well as hepatitis B which can be spread through sexual contact, may transmit between spouses via unprotected sexual activity.

2. Digestive System Diseases: Infection with Helicobacter pylori is a common digestive condition that can spread between partners through behaviors like kissing or sharing eating utensils, potentially leading to gastritis, gastric ulcers, and other gastrointestinal issues.

3. Skin Conditions: Skin diseases such as flat warts, athlete's foot, and fungal nail infections may spread between spouses due to sharing personal items like slippers or foot basins.

4. Metabolic Diseases: Metabolic conditions such as diabetes and hypertension are closely linked to unhealthy lifestyles. If both partners consistently consume high-sugar, high-salt diets and lack physical activity, they may develop these diseases simultaneously.

5. Couple Cancers: Although cancers such as lung cancer, colorectal cancer, and liver cancer are not contagious, couples who live together long-term often share similar dietary habits and living environments, thereby increasing their concurrent risk of developing cancer.

Couples should jointly pay attention to health, undergo regular medical check-ups, and maintain healthy lifestyle habits—such as eating separate meals, frequent handwashing, and good personal hygiene—to reduce the risk of developing diseases together.
