What is Neonatal Diabetes — Detailed?

Neonatal diabetes mellitus is a rare monogenic disorder diagnosed in infants under 6 months of age. It includes permanent neonatal diabetes (PNDM) and transient neonatal diabetes (TNDM) subtypes.

The most common causes are KCNJ11 and ABCC8 mutations affecting the K-ATP channel, leading to defective insulin secretion. 6q24 abnormalities are typical for TNDM. Wolcott-Rallison syndrome (EIF2AK3) and IPEX may present with neonatal diabetes.

Genetic diagnosis is essential because most KCNJ11/ABCC8 cases respond dramatically to high-dose oral sulfonylureas, allowing transition off insulin. Early diagnosis prevents diabetic ketoacidosis and improves long-term outcomes.

Symptoms

Hyperglycemia in the first 6 months
Failure to thrive
Polyuria with severe dehydration
Diabetic ketoacidosis at presentation
Low birth weight (especially TNDM)
Developmental delay (DEND syndrome)
Hypotonia in some KCNJ11 cases

Risk Factors

Onset under 6 months of age
Consanguinity (autosomal recessive forms)
Family history of diabetes
Intrauterine growth restriction
6q24 imprinting abnormalities
Pancreatic dysgenesis
Severe insulin resistance syndrome

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Hyperglycemia in infancy
  • Failure to thrive with polyuria
  • Diabetic ketoacidosis under 6 months
  • Low birth weight infant with hyperglycemia
  • Recurrent dehydration episodes
  • Need for genetic testing

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
