my husband has low levels of hemoglobin and low calcium, but had an iron induction just last week.  He had gastric bypass surgery 8 years ago and has maintained weight of 220 lbs. at 5ft. 9ins. age 66.  He has some arterial blockage being monitored and bp undercontrol with meds.  Should we be concerned
Hi, Low hemoglobin levels, will increase pressure on heart, to pump more for the oxygen to be delivered. If it is below 6-8, it is critical that it should be increased. Iron therapy if iron deficiency is found is ideal. Due to gastric bypass, impaired absorption is going to be present, and he might require injectables. Also, It B12 and folic acid might need to be taken. Low calcium could lead to bone resorption and increased risk of fracture. It D and calcium supplements are necessary to reduce the risk. Some amount of resistance exercise and fall prevention measures also needs to be taken. Any further queries, happy to help again.
