What type of specialist primarily focuses on issues related to the large intestine?

A gastroenterologist is a medical specialist who primarily focuses on the diagnosis and treatment of conditions affecting the gastrointestinal tract, which includes the large intestine, also known as the colon. This specialist deals with a variety of issues such as inflammatory bowel disease, irritable bowel syndrome, colorectal cancer, and other disorders related to digestion and nutrient absorption.

In contrast, a cardiologist specializes in the heart and circulatory system, focusing on conditions such as heart disease and hypertension. A neurologist is concerned with the nervous system and issues such as epilepsy or migraines, while a dermatologist focuses on skin disorders. Each of these specialists has a distinct area of expertise, but only the gastroenterologist directly addresses concerns related to the large intestine, making this option the most appropriate choice.
