Uncommon forms of diabetes.

Area of Science:

• Endocrinology
• Internal Medicine
• Clinical Diagnostics

Background:

• Diabetes mellitus is a prevalent condition encountered by all clinicians.
• Type 2 and type 1 diabetes are the most common forms.
• Atypical diabetes presentations require consideration for proper diagnosis and management.

Purpose of the Study:

• To review key features, investigations, and treatments of less common diabetes mellitus types.
• To inform clinicians about differential diagnoses for atypical diabetes.
• To emphasize the impact of specific diabetes forms on clinical practice.

Main Methods:

• Literature review focusing on specific atypical diabetes types.
• Summarization of clinical features, diagnostic approaches, and therapeutic strategies.
• Inclusion of MODY, LADA, ketosis-prone diabetes, and secondary diabetes.

Main Results:

• Maturity Onset Diabetes of the Young (MODY) presents unique genetic and clinical characteristics.
• Latent Autoimmune Diabetes in Adults (LADA) shares features of type 1 and type 2 diabetes.
• Secondary diabetes, linked to conditions like pancreatic cancer and hemochromatosis, necessitates distinct management pathways.

Conclusions:

• Recognizing atypical diabetes forms is essential for appropriate clinical management.
• Early and accurate diagnosis of MODY, LADA, and secondary diabetes improves patient outcomes.
• Clinicians must be aware of the diverse etiological factors and presentations of diabetes mellitus.
