A Conceptual Study of Madhumeha in Relation to Diabetic Neuropathy: An Integrative Review of Ayurvedic and Modern Perspectives

Madhumeha, a subtype of Prameha described in classical Ayurvedic literature, is a chronic metabolic disorder characterized by excessive urination with sweet urine and progressive tissue depletion. It is primarily considered a Vataja Prameha, with Kapha predominance in the early stages, eventually leading to Dhatu kshaya and Ojakshaya. The vitiation of Tridosha especially Vata and Kapha along with disturbances in Meda, Mamsa, and Kleda, results in systemic metabolic dysfunction. In advanced stages, Madhumeha presents with various complications (Upadravas), including neurological manifestations such as Suptata (numbness), Daha (burning sensation), and Sparsha-hani (loss of sensation), which resemble peripheral neuropathy. Etiological factors include Santarpanajanya Nidana, such as excessive intake of sweet foods, sedentary lifestyle, physical inactivity, and psychological stress, highlighting its multifactorial nature. In modern medicine, Madhumeha is closely correlated with Diabetes Mellitus, a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency or resistance. One of its most common complications is diabetic neuropathy, affecting nearly 50% of patients. Its pathogenesis involves oxidative stress, polyol pathway activation, advanced glycation end-product accumulation, microvascular damage, and nerve ischemia, leading to progressive nerve dysfunction. This integrative review analyzes classical Ayurvedic and modern biomedical literature to establish a correlation between Madhumeha and diabetic neuropathy. It reveals parallels between Ayurvedic concepts such as Dhatukshaya and Vata vitiation and modern mechanisms of neuronal damage. Ayurveda advocates a holistic management approach including Nidana Parivarjana, Shodhana, Shamana, and Rasayana. An integrative approach may enhance prevention and management, emphasizing the need for evidence-based interdisciplinary research.
