Hi, What I feel is there will be changes in the overall metabolism after the hysterectomy and many people have similar complaints. What we advice is to take the oral supplement of Potassium and calcium. Sometimes Vitamin D as well. Because of hormonal changes happening within the body there might be a need of additional supplement. Put yourself to aerobic/general exercise to improve the absorption and also try doing exercises for stabilizing the core and pelvic floor. Rest assured you should do well. My mother herself went same surgery and had similar symptoms. but now all good as it was monitored carefully the post surgical management with oral supplements and exercise. Hope I have answered your query. Let me know if I can assist you further. Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist
