Weakened Immune System
People with a compromised immune system, such as children, the elderly, or HIV patients, are often at a higher risk of developing ulcerative colitis. This is because viral or bacterial infection would occur easily in their digestive tract and trigger immune responses. When the body attempts to fight off foreign invaders, your digestive system, include the intestine will become inflamed, thus causing ulcerative colitis. Fortunately, the issue would go away when the infection is treated. [6]
