Introduction
‘Maheshu Uccha Madhu Ev Madhuram Mehati’ which means that one which is superior to all other Meha and is categorized by passage of urine as sweet as honey i.e., Madhumeha.[1] ‘Mahatyaya’[2] is the term given to Madhumeha in classical Samhitas which means Mahavyapattikara (causing severe complication).
It shows complex disease process involving all three Dosha’s (Vata, Pitta, Kapha) and most of the body components i.e., Dushyas (Rasa, Asrika, Mamsa, Meda, Majja, Shukra, Ambu, Vasa, Lasika, Ojas and Sweda).[3] Moreover, the involvement of Asthi cannot be ignored
as growth of Kesha and Nakha which is described in Purvarupa.[4]
Nidana of Madhumeha
Avyayma[5] (lack of exercise), Atapasevana[6] (exposure to sunlight), Agni Santapa (Proximity to fire), Ajirna Bhojana (indigestion), Anashana (fasting),Vega Dharana (controlling natural urges), Abhighata (Injury), Divaswapna (day sleep), Alasya (lazy), Krodha (anger), Shoka (sad), Atiyoga of Vamana, Virechana, Asthapana Nasya.[7]
Dietary factors: Overindulgence in yoghurt, fish, milk, new grains, sugar-containing foods and beverages, and jaggery (raw cane sugar) foods that are cold, sweet, difficult to digest, and slimy in nature.[8]
Lifestyle factors: A sedentary way of life, excessive sitting, sleeping too much, napping during the day, indolence, and lack of exercise.[9]
Psychological factors: Mental illness brought on by psychological extremes like bipolar disorder and Vishada (depression).
Samprapti (Etiological factors)
The person intaking food substances which are having Guru, Snigdha quality, Amla and Lavana Rasa, Navannapana, in large quantity and indulge in excessive sleep, avoiding exercises, sitting in a same place for longer duration, abstinence of mental activity and also not performing the Shodhana process in a proper time are prone to get Prameha. According to Acharya Sushruta, if Prameha is left untreated, it gets converted into Madhumeha and becomes incurable.
Acharya Vagbhatta says that the urine of Madhumehi will be similar to that of Madhu. Prakupita Vata plays an important role in Samprapti of Madhumeha. Vata Prakopa occurs mainly due to two causes - Dhatu Kshaya and Marga Avarodha.
Madhumeha Samprapti can be can be broadly classified into 2 types - Avaranjanya and another is Kshayatmaka. Avarnajanya is by Pitta and Kapha and Kshyatmaka is due to Vata. Chala Guna of Vata declines by Avarana of Kapha and pitta and hindering normal nerve impulse conduction and worsening of myelin sheath.
The fatty white matter that surrounds nerve cells' axons to form the electrically insulating layer is known as the myelin sheath of neurons. Proteins make up 15-30% of myelin, lipids make up 70-85% of the dry mass, and water makes up about 40%.
On later stage of disease due to Vata-Prakopa occurs which causes Dhatukshaya and eventually leads to Ojakshaya.
As Ojas is the essence of Sapta Dhatus. Oja is of two type Para and Apara Ojas, Pramana of Apara Oja is Ardha Anjali Pramana and is Sleshmika in nature, and this Apara Oja losses through urine in this Vata Prakopa stage of Madhumeha. In both stages, Avaranjanya and Kshyajanya proper functioning of Vyana Vayu doesn’t occur which leading to signs and symptoms of diabetic neuropathy. Long-term exposure to the same Nidana causes ongoing vitiation of Dosha, Dhatu and Mala. As a result, the disease advances to the point of complications that can lead to a number of different diseases collectively referred to as Upadrava.
