How Is Diabetes Mellitus Diagnosed?

Diagnosis usually includes a medical history, symptom review, blood sugar testing, A1C testing, medication review, and evaluation for complications when symptoms suggest nerve, stomach, bowel, liver, or digestive involvement.

Diagnostic Tools May Include

Blood Sugar and A1C Testing

A1C, fasting glucose, random glucose, or oral glucose testing may be used to confirm diabetes and understand blood sugar patterns.

Digestive Symptom Review

The care team reviews nausea, fullness, vomiting, bloating, reflux, constipation, diarrhea, weight change, appetite changes, and medication side effects.

GI Testing When Needed

Endoscopy, colonoscopy, imaging, stool testing, breath testing, or gastric emptying studies may be considered when digestive symptoms persist.

Why a GI Review May Be Helpful

Diabetes-related digestive symptoms may overlap with reflux, ulcers, IBS, constipation, gallbladder problems, celiac disease, inflammatory bowel disease, or gastroparesis. Testing helps separate possible causes.
