Hello there. I can understand your concern. Your question is incomplete because a few more details are required. I would suggest you get a blood workup done to check for your Haemoglobin percentage. Have a high Protein diet and exercise daily to build up muscle mass. Have lots of greens and vegetables and also fruits so that you derive a lot of b vitamins and other required minerals. Also take a cap. Gibkoba-m daily once a day after food. Hit the gym. All the best. Best regards. Dr. Anil Kumar Jain.
