Magnesium is an essential element and mineral in the body. The major benefit of magnesium is muscle functioning and the intake of magnesium is very much required for the normal metabolisms. However, it could be extremely dangerous if the intake of this mineral exceeds the limit. Generally, Kidney plays a vital role in maintaining the Magnesium level in the body. The excess of magnesium gets filtered out. But majorly due to Kidney impairment and excess intake of Magnesium, body suffers from a unique and rare disease. The disease is called Magnesium Overdose. It is often referred as Magnesium Toxicity or Hypermagnesaemia. The overdose of Magnesium may cause several damages to the body like breathing problems, walking problems and others and unawareness of HyperMagnesaemia may even become life threatening.

    I can’t help but noticing reading through some of these articles the grammar and spelling is quite poor. “May become fatal for life”, “People even cannot walk and often falls down while walking” “doctors generally advises”. Etc etc . Other then that very informative.

    I think I may have overdosed on magnesium recently . I take a magnesium & b6 combined supplement the dosage is 400mg of magnesium & I always take it just before bedtime to help me sleep, however I have had a few episodes over the last year where after about an hour after going to bed I wake feeling light headed my breathing is shallow and my hands & feet feel cold & clammy , it is a frightening experience as I feel I can’t breathe properly.On the occasions it has happened I get up, go downstairs get a drink of water & walk about to try & warm up & get my blood pumping as I feel like my blood pressure is low I don’t know if this is correct to do I just do what my body feels like it needs to do after about an hour it usually subsides & I go back to bed. These episodes as I call them always happen an hour or so after going to bed never ever in the day so I questioned myself what I was doing before bed that may be causing this I went through things such as antihistamine sweeteners and even self tan that I had on one time when it happened & finally I looked up magnesium the symptoms of overdose struck a cord with me but even so it was stated that overdose is rare so I went to see my doctor to double check, she didn’t seem convinced it was the magnesium but adviced me to halve my dose & come off the antihistamine so I did but a few months later it happened again, I came off the sweetners, had about 6 weeks no symptoms until yesterday I had the worst one yet. During the day I had eaten lots of whole grains nuts and hummus at lunch, for dinner I had a soup with spinach & chickpeas just before bed I had 2 oatcakes with a good smothering of peanut butter and some almonds all these things are good doses of magnesium & also at bedtime my half dose of magnesium. An hour later I woke short of breath my hands cold & clammy & also this time loose stools I felt restless and this time my heart felt fluttery I felt better sitting up but every time I went to bed I felt I couldn’t breathe my heart was thumping & I couldn’t get warm I seriously considered going to hospital convinced I was having a heart attack I tried once more to sleep & told my partner if it happens again we’re going to A & E thankfully after 4 hours of suffering I eventually fell asleep. I eat healthily I exercise I’ve never smoked don’t drink alcohol much (occasional drink of red wine ) so I’m assuming my heart is fine I am 51 but my blood pressure has always been good when checked by my doctor I can only assume it’s the magnesium so today I have thrown the supplements away & drinking lots of water to flush my system & will rely on food for my magnesium from now on however if it happens again I will go to A&E. I’m telling my story so others can see it is possible to overdose on magnesium if you don’t pay attention to what you’re eating & then taking a supplement it can be easily done I feel this attack was very close in endangering my life be very careful & pay attention to your body.

    I’m having one now! I did not know how it could affect your body. If I continue to feel this bad I will go to my doctor but I am warning people to never do this!
