What Are 10 Common Diseases of the Digestive System?
Digestive health plays a critical role in overall well-being, yet many people experience gastrointestinal symptoms without understanding their cause. Questions like what are 10 common diseases of the digestive system? often arise when symptoms such as abdominal pain, bloating, acidity, or altered bowel habits begin to affect daily life. The digestive system includes the esophagus, stomach, intestines, liver, pancreas, gallbladder, and rectum, all of which can be affected by disease.
Recognizing common digestive disorders, their symptoms, and when to seek medical care is essential for early diagnosis and effective management.
Understanding the Digestive System
The digestive system is responsible for breaking down food, absorbing nutrients, and eliminating waste. Any disruption in this complex process can lead to discomfort, nutritional deficiencies, or chronic illness. Digestive diseases can range from mild, temporary conditions to long-term disorders requiring continuous care.
What Are 10 Common Diseases of the Digestive System?
Below are ten frequently encountered digestive system diseases seen across different age groups.
