E61.3

Clinical Causes: Inadequate dietary intake of manganese-rich foods Malabsorption conditions such as Crohn's disease or celiac disease Chronic alcohol consumption, which can impair absorption Certain medications that interfere with mineral absorption High intake of calcium or iron supplements, which can hinder manganese absorption Premature infants or those fed with specialized formulas lacking sufficient manganese Prolonged use of parenteral nutrition without adequate mineral supplementation

Key Symptoms: Weak and brittle bones, increasing the risk of fractures Impaired growth and development in children Altered blood sugar regulation, potentially leading to issues like hypoglycemia Skin abnormalities such as dermatitis or rashes Reduced fertility or reproductive challenges Poor wound healing Muscle weakness and fatigue Mental changes including irritability or mood disturbances

Diagnosis Path: Diagnosis of manganese deficiency typically involves blood tests measuring manganese levels, alongside assessments of dietary intake and medical history. Since manganese levels are difficult to evaluate precisely, doctors may rely on clinical signs and symptoms, as well as related blood work, to determine deficiency. Imaging or bone density tests might also be used if bone health is a concern.

Treatment Protocols: Treatment focuses on correcting the deficiency through dietary improvements or supplementation. Dietary sources rich in manganese include nuts, seeds, whole grains, legumes, and leafy green vegetables. If necessary, healthcare providers may recommend manganese supplements, especially in cases where absorption is impaired or deficiency is severe. Monitoring manganese levels during treatment ensures safe and effective correction, as excess manganese can be toxic. Addressing underlying causes, such as malabsorption or medication interference, is also crucial for long-term health.
