According to Ayurveda principles its PANDU rog. Not necessarily iron infusions will do it away. Constipation can well be caused by iron intake also. Your modern doctor has reached conclusions after a series of tests and procedures and has treated you as well. You do not seem satisfied. It s not bad to try alternative route. In PANDU, due to vitiation and imbalance of three body humors viz. Vata, Pitta, Kapha various diseases are manifested. Rasa to Shukra - seven elements ( of which one is rakta - the blood) get deteriorated. To replenish rakta, first one i.e. rasa should also be in right balance. Rasa is achieved by proper appetite, digestion, assimilation and metabolism. The function starts right from saliva by salivary amylaze s action on food you take. To abridge rakta can be replenished natural way by deep breathing exercises. To facilitate iron supply, food containing iron like spinach be encouraged. To my own patients I give Punaravadi Mandoor which is safe and side effect less Ayurveda medicine and long term use is harmless. It stimulates blood formation function in the concerned organs. In the process of making this medicine, Trifla decoction is used which is known for constipation removal. How holistic it is you know now. I would give two liquids too Lohasav and Punarnavasav. See all your complaints improved in 4-8 weeks. It s slow because its natural - nothing synthetic. If you need more guidance, you can find any Ayurveda doctor near you or contact through HCM. So deep breathing, iron rich food, some herbal medicine which are safe, will lead you to normalcy without need of procedures and without fear of side effects. Hope it helps you.
