Overview

Insulinoma must be differentiated from other diseases that cause features of hypoglycemia like palpitations, profuse sweating, dizziness, such as [differential dx1], [differential dx2], and [differential dx3].

OR

Insulinoma must be differentiated from the exogenous use of insulin, drugs causing hypoglycemia like sulfonylureas.

Differentiating insulinoma from other Diseases

• [Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
• [Disease name] must be differentiated from [[differential dx1], [differential dx2], and [differential dx3].

• As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].

Preferred Table for differentials for Hypoglycemia
