Patient's Query

Hello doctor,

I am wondering about what might be causing elevated magnesium levels in my blood test results. My laboratory results show that my magnesium levels are high at 1.34 mmol.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Elevated magnesium levels to this high are not considered significant. Changes in serum magnesium can be seen if you are dehydrated if you drink alcohol, some medicines like if you take antacids for stomach issues, and if you have kidney disease. So, be careful about your water intake and stop alcohol if you take it.

Additionally, see if any medicine, supplements, or tablets you take have magnesium in them so that may be the main reason.

Your iron levels are low in the report. Take proper iron supplements, and do not worry about magnesium levels much. I recommend repeating the test after a month after proper water intake and taking care of the rest of the things I mentioned and then you may consult again.

It is important to take care of iron deficiency which is significant in your case; take iron-rich foods and supplements and increase vitamin C intake.

I hope I have answered your question.

Let me know if I can assist you further.

Regards.

Patient's Query

Hi doctor,

Thank you for your reply.

Unfortunately, I realized I forgot to send the first page of the laboratory report, which is also a great concern of mine.

I have had previous laboratory report with a neutrophil count of approximately 1.8, then it increased and returned to a normal level of 2.2 and then it dropped again and now they are at an all-time low of 0.9, along with a low WBC count as well. Can you let me know if this is related to the high magnesium levels?

I have not taken any magnesium supplement or antacid, and I am currently undergoing testing for cortisol levels in the morning and evening to rule out Addison's disease. Is there something you suspect from the labs? What would cause low neutrophils, low ferritin, and high magnesium levels?

Thank you.

Hello,

Welcome back to icliniq.com.

It is significant that your white blood cells (WBCs) are low and you also have neutropenia (low WBC count). But the most important thing is whether you have any symptoms because laboratory reports may vary and go up and down in different life stages, such as infections and bone marrow failures reducing the WBC count. if you do not have repeated infections and your life is healthy without any problems, there is no need to worry much because this can be some familial neutropenia

Some people have cyclical neutropenia and their neutrophils reduce after two to three months and then come back to normal. While some people have severe infections during this time, some may not.

If you do not suffer from any problem, it is fine, and you do not have to worry. However, if problems arise, you have to get the necessary treatment, like G-CSF, which increases white cell count.

Magnesium is not so high that you worry about it. Take a detailed count of your dietary intake and get your renal function tests done, as some diets may cause raised magnesium levels. Additionally, try to get iron supplements

While there is not a direct correlation between magnesium and neutrophils except that when neutrophils destroy bacteria, then magnesium may be released. So it may happen in some infections. You give some time to your body to cover up these and do not take stress if it is causing no such problem to you

Repeat tests after two months and see if it persists. Take iron supplements and improve your diet with exercise to control your weight and cholesterol, and it would solve the majority of the problems.

I hope I have answered your question.
