Q: I am a 67 years old diabetic man having pain around the knees. My blood sugar levels are in control. I have started taking calcium supplements regularly though I drink milk daily. But I came to know that regular intake of calcium supplements might lead to kidney problems. Is it safe to take calcium supplements daily?

A:Please see your doctor to identify the cause of knee pain first. I hope the supplementation with calcium has started only as per prescription by your doctor. It is true that higher than normal levels of calcium may cause kidney trouble. Blood tests may be done once every 6 months to determine serum calcium levels. Your knee pain may be related to injury or even overweight. Please consult with your doctor to rule these out before you start taking calcium. Since you mention that you take milk regularly, it is doubtful that low calcium levels are a cause of your knee pain.
