Do you need to see a gastroenterologist? You may have stomach symptoms—and might not be sure which type of doctor to call. Take a look at the top gastrointestinal (GI) issues that could require treatment from a specialist.

Unexplained Bleeding

Rectal bleeding is a symptom you should never ignore. This surprising—or sometimes even shocking—symptom may have a few different potential causes. Some causes of rectal bleeding, such as hemorrhoids or an anal cut/fissure, aren't typically serious. But rectal bleeding could also signal a more significant issue, such as diverticulitis, an anal abscess, inflammatory bowel disease, polyps, or cancer.

Before you jump to the worst conclusion, consult with a gastrointestinal (or GI) specialist. The doctor will need to take a full health/symptom history, examine the area, and order tests (such as a fecal occult blood test or a colonoscopy) before diagnosing a colorectal condition. 

Bloat That Won't Go Away

The full, tight feeling that comes along with a bulging belly isn't always a cause for alarm. Bloating is a common sign of gas—and won't always require help from a GI specialist. But if bloating doesn't resolve with conservative or at-home treatment or persists, you may need to see a gastroenterologist. Chronic bloating could signal an inflammatory bowel disease, gastroparesis, or bacterial infection. 

Bowel Habit Changes

Some degree of irregularity is normal. You can't expect to have a bowel movement on schedule every day of your life. Stress, physical activity (or lack of physical activity), some medications, your diet, and hydration/dehydration can affect bowel movement regularity. A temporary viral or bacterial infection can also cause a noticeable change in bowel habits.

Bowel habit changes could include more than just more or fewer movements than usual. These types of changes could also include dry stools, hard stools, loose or watery stools, mucus during a bowel movement, or a change in color. 

Colorectal conditions such as celiac disease, irritable bowel syndrome, Crohn's disease, and ulcerative colitis require a consultation with a GI specialist. If bowel changes persist, you have abdominal pain, you can't pass gas, you can't pass stool for several days, you have unexplained weight loss, you see pus, mucus, or blood in your stool, or you have other concerns, contact a GI doctor or gastroenterology surgeon for an exam and consultation. 

Abdominal Pain

Everyone has had some degree of belly pain. A stomachache from overeating, a GI virus, or even muscle strain can cause abdominal discomfort. If you have pain that doesn't resolve on its own or respond to at-home treatments, pain with other worrisome symptoms, or severe pain, see a gastroenterologist for a diagnosis and treatment.
