Expert Care for Atypical & Rare Forms of Diabetes – Bronxville & Westchester, NY

Not all diabetes is Type 1, Type 2, or gestational. At Sequoia Medical 360, we specialize in identifying and managing atypical, rare, and misclassified forms of diabetes that often go unrecognized in standard care. These patients may be misdiagnosed, placed on the wrong medications, or left without the right tools to control their disease.

Our concierge model, led by Dr. Tony Mathews — quadruple board-certified in Endocrinology, Diabetes & Metabolism, Obesity Medicine, Internal Medicine, and Clinical Lipidology — ensures precision diagnosis and tailored therapy for even the most complex cases.

Why Accurate Diagnosis Matters

Misclassification of diabetes can have lifelong consequences. Patients with certain forms may respond poorly to standard Type 2 medications, or they may need early insulin — but not recognize it until years later. Genetic or secondary forms of diabetes also carry unique risks for complications and demand a different approach to nutrition, medication, and long-term monitoring.
At Sequoia, we leverage advanced diagnostics, genetic testing, and careful endocrine profiling to get the diagnosis right — and build a care plan that fits your biology.

Forms of Diabetes We Manage

Latent Autoimmune Diabetes in Adults (LADA, or “Type 1.5”)

What it is: A slow-progressing autoimmune form of diabetes that develops in adulthood, often misdiagnosed as Type 2.
Clues: Patients may initially respond to oral medications but eventually require insulin as pancreatic beta-cell function declines.
Our approach: Autoantibody and C-peptide testing to distinguish LADA from Type 2; personalized transition planning for insulin therapy when needed.
Monogenic Diabetes (MODY)
What it is: Caused by single-gene mutations affecting insulin secretion
Clues: Strong family history, early onset (adolescence or young adulthood), often mistaken for Type 1 or 2.
Our approach: Genetic testing when indicated; some MODY subtypes can be managed with oral agents instead of insulin, dramatically simplifying care.
Type 3c Diabetes (Pancreatogenic Diabetes)
What it is: Diabetes secondary to pancreatic disease (chronic pancreatitis, surgery, trauma, pancreatic cancer).
Clues: Patients may have both insulin deficiency and digestive enzyme deficiency.
Our approach: Dual management of glucose and pancreatic exocrine function, including enzyme replacement and nutritional support.
Ketosis-Prone Diabetes (KPD)
What it is: A form of diabetes that presents with diabetic ketoacidosis (DKA), but without classic autoimmune destruction of beta cells.
Clues: Common in adults of African, Hispanic, or Asian descent; patients may initially need insulin but can sometimes transition to oral therapy.
Our approach: Careful classification with antibody and insulin reserve testing; individualized plans that balance safety with the possibility of insulin withdrawal if appropriate.
Steroid-Induced Diabetes
What it is: Hyperglycemia that develops in the setting of chronic or high-dose glucocorticoid use.
Clues: Blood sugars rise during steroid therapy; often resolves when steroids are discontinued.
Our approach: Anticipatory monitoring, insulin or non-insulin adjustments during steroid use, and strategies to minimize long-term risks.
Secondary & Syndromic Diabetes
Causes: Hormonal disorders (Cushing’s, acromegaly, pheochromocytoma), medications (antipsychotics, immunosuppressants), or genetic syndromes (e.g., Wolfram syndrome, mitochondrial diabetes).
Our approach: Address the underlying driver in parallel with diabetes management, collaborating closely with other specialists.

Our Diagnostic Toolkit

To differentiate these forms of diabetes, we use:

C-peptide and autoantibody panels → to distinguish Type 1, LADA, and KPD.
Genetic testing → when MODY or syndromic diabetes is suspected.
Pancreatic imaging → for suspected Type 3c.
Medication review → to identify steroid- or drug-induced diabetes.
Advanced labs → full metabolic, lipid, and cardiovascular profiling to guide therapy.

Tailored Treatment Strategies

MODY: Oral therapy instead of insulin when possible.
Type 3c: Insulin + pancreatic enzyme support.
KPD: Early insulin, with reassessment for transition off insulin if safe.
Steroid-induced: Time-limited insulin or non-insulin agents matched to steroid dosing.
LADA: Early planning for insulin, combined with cardiometabolic prevention.
Secondary forms: Root-cause management plus individualized glucose control.

The Sequoia Medical 360 Advantage

Rare expertise: Advanced endocrinology care for conditions most physicians rarely see.
Direct Physician Counsel: Ample, scheduled exam time and streamlined communication to review results with the depth your physiology requires.

Collaboration: Seamless coordination with gastroenterology, oncology, pulmonology, or genetics when needed.

If Your Diabetes Doesn’t “Fit the Box”

If you’ve been told your diabetes is “unusual,” or if standard treatments aren’t working as expected, you may have a form of diabetes that requires deeper evaluation. At Sequoia Medical 360, we specialize in finding answers that others miss.
